When it comes to alarm panels behaving as Z-Wave Controllers, it should be easy to determine if a device is compatible or not. However, we've found that in some cases, not all Z-Wave devices are equal. Z-Wave locks by Schlage have been known to have compatibility issues with certain panels.

Alarm Grid has often stated in our documentation that we prefer that our customers use the Yale or Kwikset Z-Wave locks. We've seen issues with Schlage locks over the years and we haven't really gotten satisfactory answers as to why. We've had customers tell us that they've worked with Schlage, and we have worked with Resideo and Honeywell Home. Sometimes they will work, but other times the customer winds up changing to a different lock manufacturer, or just not using the locks with their panel.

When you look at the most current Lyric Z-Wave Compatibility Chart, which is dated 05/19, and is an official document produced by Honeywell Home, it shows that Schlage Z-Wave locks are compatible. This information is based on engineering and quality assurance testing. But testing and daily use are two different things. Engineers can never think up every scenario to test, no matter how hard they may try. So, once a customer attempts to use the products together in their own home or business, some unforeseen factors may arise and cause issues.

We recently had a customer attempting to use a Schlage Z-Wave lock with a Lyric Security System. When the lock is paired with the panel, the batteries drain very quickly, within one to two weeks. When the lock is used as a stand-alone device, the batteries appear to have a normal life. So, we asked Resideo Technical Support for their input. They suggested that the Schlage locks not be used with the Lyric, ProSeries, or Tuxedo products at this time. There is some conflicting information, certain locks may work with the ProSeries panels while others do not, but it may be best to avoid Schlage locks with these panels for now unless you can wait to use the panel and lock together until the issues are resolved.

The Lynx Series panels appear to support the Schlage locks when the L5100-ZWAVE is employed, but certain conditions must be met. The lock and the panel must be within 12 inches of one another during the pairing process, and must remain at this distance for a full two (2) minutes before either is moved. This allows the full pairing process to be completed. Also, the handing process must be completed immediately following pairing. Resideo engineers are working with Schlage to resolve any issues with those panels that have them, and they hope to have a resolution some time soon, possibly in early 2022.

If you have any thoughts about Schlage Z-Wave locks and their use with any of the Resideo or Honeywell Home alarm systems, drop a comment in the area below and lets get a conversation started. We offer feedback directly to all our vendors on behalf of our customers. We're honored to be your voice.

Until now, only alarm systems manufactured by Resideo, Honeywell Home, or Honeywell could be used with Total Connect 2.0. That changes with the new LTEM-P Series communicators. Some DSC and Interlogix panels can now be connected to and used with TC2. A supplemental wiring guide is provided.

The LTEM-PA AT&T LTE Communicator, and the LTEM-PV Verizon LTE Communicator available from Resideo can be used to send alarm signals on behalf of all the same VISTA panels that were compatible with the older AlarmNet communicators such as the Honeywell LTE-IA, and the Honeywell LTE-IV. In addition, certain versions of some of these panels can also be used with Total Connect 2.0 Remote Services when one of these communicators is attached to it.

With the release of the LTEM-P Series communicators, DSC PC1616, DSC PC1832, and DSC PC1864 panels can support both reporting through the communicator when it is connected to the panel's keypad bus and integration with Total Connect 2.0. In addition, Interlogix NX8E, NX-4V2, NX-6V2, and NX-8V2 panels can also be used with the LTEM-P Series communicators to both send signals, and integrate with TC2.

With the DSC PC Series panels, this is purely a keypad bus connection. The communicator's RX, TX, and Ground terminals will connect to the DSC panel's Green, Yellow, and Black keypad bus terminals. On the Interlogix NX Series panels that are supported, there is a connection to RX on the communicator from the terminal marked DATA on the panel's keypad bus. COM from the NX Series panel will connect to GND on the Communicator. In addition to this, the LTEM-P Series communicator will require a Resideo PRODCM Dialer Capture Module, which will connect to the panel's Tip and Ring terminals. The PRODCM will be installed inside the communicator. Panel signals are sent via the PRODCM, and Data Bus information for Total Connect 2.0 is sent from the bus.

There are some programming options that will need to be configured properly, for example the NX panel must be set to report in Contact ID format. In fact, all signals for both panel types will be sent to the monitoring station using Contact ID. The wiring connections should be made while both the panel and communicator are powered down. The alarm panel is powered up first, and all troubles, faults, and alarms must be cleared. Once they are, power up the communicator and it should begin to scan the panel's bus for zone information. This process can take up to ten (10) minutes.

This is not meant to be a step-by-step guide to setting up this feature, it's just an introduction to the feature for those who may not be aware that it is available. We offer an FAQ for using the DSC panels with TC2 here. If you have one of the compatible DSC or Interlogix panels, and you are considering using it with one of the LTEM-P Series communicators, check out the Resideo LTEM-P Series Installation Guide, the Resideo Supplemental Install Guide for Non-VISTA panels, and for those using a compatible Interlogix NX-Series panel, also check out the Resideo PRODCM Install Guide. We have not yet had an opportunity to create our own in depth FAQs for this process on the Non-VISTA panels, but we will get to those in the near future.

Have any thoughts about Resideo and Honeywell Home finally embracing the use of their communicators with competitor's panels? They offered a dialer capture module in the past, but it installed outside the communicator and was somewhat unwieldy. Leave a comment below and tell us what you think. We always look forward to hearing from our readers!

In recent years, consumers have seen more information about IP ratings. Probably the most common example is with regard to cell phones. First came the IP67 rating, and then IP68. Cameras, particularly ones for outdoor use, also have an IP Rating. IP Rating standards are controlled by the IEC.

The IEC is the International Electrotechnical Commission. They are the official body that defines the IP Code. The code is defined in IEC standard 60529. In europe, it is EN 60529. The purpose for the code is to provide specific information about ingress protection, as opposed to the use of terms like waterproof, or water resistant. One company's water resistant, may be another company's waterproof. The IP Code is intended to take the leeway out of these descriptions.

The digits in an IP rating indicate conformity to protection under certain conditions. When you see a 0 in an IP rating it means that no protection is provided for that particular portion of the code. An X means that there is not enough data to determine the amount of protection. IP ratings will never have a - in them, so a product claiming to have a rating of IPX-8 is providing invalid information.

There are four (4) digits possible in an IP Code. For our use, only the first two (2) digits, which are mandatory, will be covered. Digit 1 describes the level of protection that an enclosure provides against access to hazardous parts, and the ingress of solid foreign objects. Digit 2 indicates the level of protection that an enclosure provides against harmful ingress of water. It should be noted that the ratings for water ingress are not cumulative. This means that just because something has a Digit 2 rating of 7, doesn't mean that it also has the Digit 2 rating of 1 - 6. If a device has protection against multiple types of ingress, it will be indicated by multiple ratings separated by a slash, for example, IPX5/IPX6.

Digit 1: Protection Against Solid Objects/Particles

Digit 2: Protection Against Liquid Ingress

There is a Digit 2 rating of 9K, but it is reserved for specialty equipment so most DIYers won't be concerned with it. For that reason, we have omitted it here. So, when you see a product that has an IP66 rating, now you'll know what that means. It means the product is dust tight, and can stand up to powerful water jets without harmful water ingress.

The information for the tables above came from various enclosure manufacturer sites all over the web. I would have liked to have gotten the information directly from the IEC itself, but to download a PDF of this standard you must pay a hefty fee. For that reason, we did not get this information from the horse's mouth, as they say, but we attempted to fact-check it to the best of our ability. Any mistakes are the author's alone.

So, what do you think about the IP ratings system? Are you ready to take your phone out and give it a test? Tell us your thoughts in the comments below. Did you find this information helpful? Is there other information you'd like to see covered? Leave a comment, or shoot an email to support@alarmgrid.com. We'll do our best to be accommodating. As always, stay safe!

From the beginning, ever since place-based services have become a staple of alarm-based remote access, Alarm.com has provided a better experience than their closest competitor, Total Connect 2.0. Recently, they announced they will be rebranding, with a name change from Geo-Services to Places.

Geo-Services, soon to be re-christened Places, allows a user to create a geo-fence around any location, and then create rules for their panel and their other automation devices based on that geo-fence. For example, you could create a rule that tells the system when your iOS or Android device enters the geo-fence, turn on the porch light

Alarm.com users with Master Control, Full Control, and Custom with Notification Settings enabled can configure Places. The feature can be enabled from the customer app by selecting Menu > GeoServices > and setting the feature to enabled:

You'll be prompted to go to your devices Location Settings and choose to Allow Always in order for the Places feature to function correctly even when the Alarm.com app is not in use. Once the feature is enabled on one or more devices, you can then create a geo-fence. One of the changes that is coming in early November is the ability to manage geo-fences from the customer app. Previously, the ability to configure this option was only available through the Alarm.com website.

Since this change hasn't actually been implemented yet, there is a chance that the menu options mentioned and shown above may change. Geo-services is included in every Alarm.com plan, and there is no additional charge to enable it. Geo-services uses the phone and WIFI networks to determine the location of the geo-services enabled device, rather than the built-in GPS. This is because using actual GPS consumes a lot of battery, but for this reason, location accuracy suffers. It can be off by as much as 3km, although that's not something we've experienced personally. Also, there is a tiny amount of cellular data used when WIFI is not available. About 100 bytes of data or less per geo-fence crossed.

Available Rules and Reminders For Geo-Services

This is just a brief overview of this excellent Alarm.com feature that you may have, but may not be using. Be on the lookout for some possible changes to this feature early next month. If there are substantial changes, we'll be sure to keep you in the loop! Leave a comment below and let us know your thoughts about this, or any other alarm features. We look forward to hearing from you.

AlarmNet360 is both a website and an app that can be used to create, edit, and cancel AlarmNet accounts. Access to this website and app is only available for licensed alarm dealers who are affiliated with AlarmNet. As an end-user you will not need to have or create an AlarmNet360 account.

Being a DIYer in the alarm industry can be pretty confusing at times! Nearly all of the documentation provided with alarm systems that have historically been installed only by alarm professionals is intended only for alarm professionals. So, when you buy that new ProSeries or Lyric Alarm System, and you begin reading the installation instructions, one of the first things you are told to do is create an AlarmNet360 account. This is not something that you, as a DIYer will be able to do.

This is where Alarm Grid comes in. Alarm Grid is a DIY friendly company. We sell professional grade alarm systems to anyone who wants to buy them. Sometimes, alarm professionals purchase from us and then they go about configuring the system themselves because they have access to AlarmNet360. Sometimes, customers purchase from us and then hire their own alarm professional to install their system and that alarm professional completes the setup on AlarmNet360 themselves. But usually, when an individual buys a system from us, they then sign up for one of our no-contract monitoring plans, and then we set up their account through AlarmNet360.

The relationship between Alarm Grid and our monitoring customers is a symbiotic one. DIY alarm users choose not to pay a professional to do something that they can do themselves. That being the physical installation of the alarm equipment. With the proliferation of self-contained, all-in-one systems, installation has gotten more and more simple. A child can do it. We have several young customers in their teens who set up systems just because they enjoy doing it, and figuring out new and interesting ways to make things happen.

On the monitoring side of things, that's where restrictions start to come in. There are certain things that have not opened up to DIYers yet, and access to AlarmNet360 is one of those things. You may be thinking, "Forget AlarmNet360, what's AlarmNet?" You can read about AlarmNet here. At present, only alarm dealers can sign up for access to AlarmNet360 in order to be able to add, edit, or cancel AlarmNet accounts. Access to accounts is very tightly controlled. The only accounts that Alarm Grid can see in AlarmNet360 are accounts that are assigned to Alarm Grid, which usually means that Alarm Grid created them in the first place.

Alarm Grid chose the DIY business model in part because we have everything we need to administer accounts on the back end, but we don't have a team of installers to send out and put in systems. DIYers are our installers, and in turn we provide for them the account admin services that they are not allowed to perform for themselves. We sell reasonably priced, professional grade alarm equipment. The same equipment that just about any alarm dealer in the country will sell you, and we handle the administrative side of things, in addition to providing free, world-class technical support to our monitored customers. In exchange for that, we charge a reasonable monitoring fee with no activation fees, no cancellation fees, and no contracts. We also don't care if you buy your system from us or elsewhere. We will monitor any equipment that is within our power to monitor for the same prices we charge to monitor the equipment we sell.

So, when you crack open that new system, and start reading the instructions, skip the part where it talks about the AlarmNet360 account. Whoever you sign up for monitoring with will take care of that part. Do you have an AlarmNet communicator? Have you been stumped by the mention of AlarmNet360 in your system's documentation? Leave us a comment below and let us know if this information was helpful. We always look forward to hearing from you.

Alarm.com video customers have another great weapon in their defensive arsenal. It's called Perimeter Guard™ and it works like this. Customers with video analytics enabled and using compatible cameras can program those cameras to flash their LEDs and make noise when an intruder is detected.

All that is required in order to enable this feature is an Alarm.com monitoring plan with Video Analytics enabled. Any Alarm Grid customer who subscribes to a monitoring plan that supports video can have this feature enabled. We don't enable Video Analytics by default because we pay more for it, but we don't charge more for it. But if you want to utilize this feature we're happy to enable it for you. Both of our Platinum plans, as well as our stand-alone video plan support this feature.

The list of cameras that can be used with this feature is always growing. Basically, the camera needs to have either a visible LED or a speaker with which to make noise on. Currently, the cameras that support Perimeter Guard™ are (updated 4/23):

• ADC-V724 on firmware version 0.6.1.387+ (supports LED and Audio Alert)
• ADC-V523 on firmware version 0.6.1.387+ (supports LED and Audio Alert)
• ADC-V723 on firmware version 0.6.1.387+ (supports LED only)
• ADC-VC727P all versions (supports LED and Audio Alert)
• ADC-VC827P all versions (supports LED only)
• ADC-VC847PF all versions (supports LED only)
• ADC-VC728PF on firmware version 0.6.3.601+ (supports LED and Audio Alert)
• ADC-VC838PF (supports LED only)
• ADC-VDB770 on firmware version 02199+ (supports LED and Audio Alert)

With Video Analytics enabled and a compatible camera, the only other thing required is to set up a Video Analytics rule for each compatible camera. This is one of those features that you set, then forget. Get the setup correct, and then it'll take care of itself!

To set this feature up through the Alarm.com Customer Website, follow these steps:

1. Log into the website. Go to www.alarm.com/login and using your Alarm.com credentials log in, completing any 2-factor authentication required.
2. Click Video
3. Click Recording Rules
4. Create or Edit Rule. You can either click the pencil icon to add this feature to an existing Video Analytics rule for a compatible camera, or you can Add a new rule. To see how to create a rule using Video Analytics, check out this informative FAQ. Verify that the initial Video Analytics settings are properly configured, then click Next.
5. Choose response. In the Activates section choose the audible and visible response desired:
   
   • Camera LED response. Click to toggle the Camera Status LED to Enabled if you want the LED to respond when activity is detected. There is a Duration drop-down, select how long you want the LED response to last.
   • Camera Audio Alert. This option is only available on cameras using the 2-Way Audio feature. Click the Camera Audio Alert toggle to enable an Audio Alert. There is an Audio Sound dropdown menu. Select the type of sound you want the camera to make.
6. Click Save

To set this feature up through the Alarm.com App, follow these steps:

1. Log into the App. Open the Alarm.com app and using your Alarm.com credentials log in, completing any 2-factor authentication required. Click the Menu icon in the upper left.
2. Tap Video from the available menu. Then tap the Gear icon.
3. Tap Recording Rules
4. Create or Edit Rule. You can either click the pencil icon to add this feature to an existing Video Analytics rule for a compatible camera, or you can Add a new rule. To see how to create a rule using Video Analytics, check out this informative FAQ. Verify that the initial Video Analytics settings are properly configured, then click Next.
5. Choose response. In the Activates section choose the audible and visible response desired:
   
   • Camera LED response. Click to toggle the Camera Status LED to Enabled if you want the LED to respond when activity is detected. There is a Duration drop-down, select how long you want the LED response to last.
   • Camera Audio Alert. This option is only available on cameras using the 2-Way Audio feature. Click the Camera Audio Alert toggle to enable an Audio Alert. There is an Audio Sound dropdown menu. Select the type of sound you want the camera to make.
6. Tap Save

It's that simple! Once you have this configured, using the advanced video analytics available through Alarm.com, the rule will take care of itself. The idea is that the flashing LED and the audible sounder will scare away an intruder before they ever make it to your home. It's a pound of prevention to ward off a ton of regret.

Alarm Grid has obtained an extremely limited supply of the brand new Resideo IPCAM-WOC2 WIFI, outdoor, 1080p camera, compatible with Total Connect 2.0. After the announcement in March, 2021 that the IPCAM-WOC1 was discontinued, Resideo and Honeywell Home were left with no outdoor camera option.

Our blog in March announced that the Honeywell IPCAM-WOC1 would be discontinued. At the time, we didn't know why the camera was being discontinued. There wasn't a lot of information available then about why it was discontinued, or whether there would ever be a replacement. With Alarm.com releasing new variations of their cameras at a fast and furious pace, we were left to wonder what Resideo was thinking.

In July, 2021, we passed on to our readers that either the IPCAM-WOC1 (also sometimes referred to as the Lyric OC1) would make a return, or if not a return, that it would possibly be replaced with something very similar. It came to light that the reason the outdoor camera had been discontinued in the first place was that certain components involved in its production were no longer being produced.

Resideo was unable to source those same components elsewhere, so they are preparing to release the IPCAM-WOC2. This camera is technically not even released yet, so we don't have official documentation, with the exception of a Quick Install Guide, which frankly, contains several errors. For starters, we know for a fact that the image of the camera and its components used in the guide is incorrect. This document, much like the camera itself, will soon be receiving a face lift.

Some of the things that we know are updated in the IPCAM-WOC2, as compared to the IPCAM-WOC1 are: The Bluetooth Antenna is internal on the IPCAM-WOC2. It was external (part of the big wiring bundle) on the IPCAM-WOC1. The WOC2 will support Audio Analytics, with intelligent sound detection. The WOC1 did not support audio. The IPCAM-WOC2 comes with a 16 GB MicroSD card pre-installed, the IPCAM-WOC1 came with a 8 GB card. These are just a few things that we know about, when the full specs are released, we will update our product description with the full gamut of features and specifications.

If you've been waiting to get your hands on an outdoor 1080p camera that's compatible with Total Connect 2.0, now is your chance to pick one up. Given all the supply chain issues revolving around the global chip shortage, this is one of a handful of products that we know is currently in stock. But you had better hurry, because supplies are extremely limited. Once the units we have in stock are gone, we will likely have to wait for the full product release before we can offer any more.

We've actually heard this before. In December of 2020, we reported that Alarm.com would begin phasing out support for Edge Legacy in February of 2021, with support for that browser ending in April. However, apparently, those plans were thwarted and the new deadline is now on the horizon.

So, what is Edge Legacy, anyway? Well, when Windows 10 first launched back in 2015, Edge Legacy, then called Microsoft Edge was a part of that browser package in the same way that Internet Explorer had always been a part of the prior Windows releases. The original Edge was a HTML-based browser that Microsoft hoped would change the game for them, however, it was universally panned. I think I speak for everyone when I say, "Hated it!"

In January, 2020, Microsoft re-launched Microsoft Edge. This new version is built on Chromium, which is an open-source browser platform that was originally launched by Google, and serves as the backbone of Google Chrome as well as Opera, and Vivaldi. Since it's open-source, anyone can take it and make what they want with it.

Now that Microsoft has "embraced" Chromium, all modern browsers use open-source base platforms. Also, the use of Chromium means that the new Edge works with Chrome extensions. One of the big changes with Microsoft Edge is that it gets updated regularly and automatically, as opposed to updates being rolled out bundled with Windows updates. Microsoft stopped supporting Edge Legacy as of March 9, 2021.

So, back to Alarm.com and their announcement. Beginning Monday November 1, 2021, if a user logs into Alarm.com using either the Edge Legacy or the Internet Explorer 11 (IE11) browser, they will receive a pop-up message suggesting that they switch to a more up-to-date browser. They will continue to be able to log in using the current browser for the next two (2) months. After two (2) months, January 1, 2022, Edge Legacy and IE11 will no longer be supported for use with Alarm.com.

It is suggested that users choose Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge (the newest version) when accessing Alarm.com. Any of these compatible browsers on the most current version should provide a good, quality user experience when using Alarm.com. If you're not sure whether you have the Edge Legacy browser, or the Microsoft Edge browser, you can see the difference in the logos below.

So, what do you think about this announcement? Will it affect you or anyone you know? Some users, those that are resistant to change, may run into some issues with this. If you happen to be the technical support friend or relative everyone calls when they have a problem, you may hear about it. Let us know what you think in the comments below. We enjoy a robust dialogue with our customers!

The new ADC-V724 is the first camera from Alarm.com to offer 2-Way Audio in addition to 1080p HDR video, and IR night vision. With the integrated mic and speaker, you could easily have some fun with the neighborhood trick-or treaters while still protecting your property from vandals.

We all know that house in the neighborhood where the owners go all-out for Halloween. In some cases, it's like a haunted house attraction where, instead of having to pay to get in, you get candy if you're brave enough to get to the door. The Alarm.com ADC-V724 could help you make your house the one everybody's talking about this year!

Don't get me wrong, this camera is great all year. It just happens that it's being released at this time of year, which is fortuitous. Because, maybe you're not that house, maybe you're the other house. The one where the inhabitants turn all the lights off and pretend not to be home because they forgot to buy candy. Maybe you're in for some tricks because you don't have any treats. Well, the ADC-V724 has you covered there too. With one of these installed, you can sit inside and watch your property. If anyone shows up to play tricks, you can politely tell them through the camera that they should skip your house.

The ADC-V724 has an improved mount over previous versions of Alarm.com cameras, for better long-term stability. It also has an easier to reach Micro SD card slot, in the event you want to take advantage of the Onboard Recording feature. The minimum capacity for a Micro SD card is 32GB, maximum is 512 GB. No Micro SD card is included with the camera. It also allows you to take advantage of the full suite of Alarm.com Video Analytics, which is a powerful tool for eliminating unwarranted video captures. The ADC-V724 offers High Dynamic Range (HDR) for better light/dark contrast in low-light environments, and can work with either 2.4 GHz or 5 GHz WIFI. With the built-in microphone, audio is included in recorded clips. When it comes to providing evidence to the police, audio is often just as important to them as video evidence, so this is a great added feature.

The speaker and Micro SD card slot can be seen in this image:

What do you think about the Alarm.com ADC-V724? Are you in the market for new indoor/outdoor cameras? Will you be going all-out for Halloween, are you the house with no candy, or somewhere in-between? Leave a comment below and let us know what you think. If there's something you'd like to see us cover in our blog, you can let us know that as well. See you next time, until then as always, stay safe!

Resideo Technologies recently released a technical notification (TN #69) outlining an issue with the CELL-ANT3DB External Antenna kits. It seems that for some time, these kits have included an incorrect mounting bracket. Without the correct mounting bracket, proper mounting is not possible.

Update provided by Resideo!

The Resideo CELL-ANT3DB External Antenna kit is an outdoor rated antenna kit that supports a number of different cellular frequency bands. In addition to simply moving the antenna from the mounting location of the radio to a location outside, the CELL-ANT3DB also provides up to 3dB of signal gain to improve cellular reception for the AlarmNet communicator.

To resolve this issue, Resideo has released the technical notice listed here. All current stock has been called back and reworked to have the incorrect bracket replaced with the correct one. If you are purchasing a new CELL-ANT3DB, you can check the barcode sticker on the box. If there is a Green Dot on this sticker, the product has been through the rework process and has the correct bracket.

Image showing a reworked product with the Green Dot clearly visible:

If you recently purchased a CELL-ANT3DB from Alarm Grid and you believe your product has the incorrect bracket, contact us at support@alarmgrid.com and we will verify whether your product is affected, and will arrange to have the correct bracket shipped to you if it is. The information in the technical notice is lacking a bit, so in addition we've contacted the product manager to see if we can get some more data on either date codes affected, or images that show us what the incorrect bracket looks like, as opposed to the correct bracket. We will update this post with more information when/if it becomes available.

Update September 28, 2021

We heard from Resideo today that this issue affects a very small number of units. This error occurred on only three (3) days of production. Date codes E215, E222, and E223 are the affected production days. You can see the date code in the image above. It shows E256. If you purchase a CELL-ANT3DB Kit with one of the affected date codes, and the box has the green circle sticker mentioned and shown above, then your product is good to go. If you purchase a product with date code E256 or later, whether it has a green dot or not, the product is also good. If you purchase a product with date code E215, E222, or E223, and it does not have the green dot sticker, then you need to request a replacement mounting bracket.
