PowerG Curtain Motion Sensors

Just like most standard motion sensors, the PowerG Curtain Motion Sensors use passive infrared (PIR) technology to detect movement. The difference is that curtain motion sensors only send out a thin detection signal, instead of scanning an entire area. While a standard motion sensor will detect movement throughout an entire room, a curtain motion sensor will only respond to movement in a very specific area.

There are many situations that warrant the use of curtain motion sensors instead of regular motion detectors. If there is something else in the room that is likely to cause false alarms, then a curtain motion sensor might be preferred. Remember, ceiling fans, flowing air and strong sunlight can all potentially activate PIR motion sensors. A curtain motion sensor might also be used if a user does not want to restrict the entire room, but only a very small portion of it at the end.

If a user places a curtain motion sensor at a room entryway, they can effectively monitor for anyone entering or exiting the room. They will walk directly past the coverage signal and activate the sensor. But if a pet or person is moving throughout the rest of the room then nothing will happen. In many cases, monitoring a room's entryway is basically just as good as monitoring the room itself. If the room only has one point of access, then a curtain motion sensor may provide a perfectly acceptable solution.

The motion sensors listed on this page are part of the extensive DSC PowerG Sensor lineup. These sensors operate at 915 MHz. They are compatible with systems like the DSC PowerSeries NEO and the Qolsys IQ Panel 2 Plus. The sensors are known for their extended range and their encrypted signals. The encryption is rated at 128-bit AES. This encryption is virtually impossible to break, and it will ensure that no intruder is able to hack or takeover the sensors.

The wireless range of a DSC PowerG Curtain Motion Sensor is rated at 2 kilometers in open air. However, they will only achieve this range when used with a DSC PowerSeries NEO System. A PowerSeries NEO Panel has a larger antenna than the one used with the Qolsys IQ Panel 2 Plus. As a result, a PowerG Sensor will not have as far of a range when used with an IQ Panel 2 Plus.

A PowerG Sensor used with an IQ Panel 2 Plus will only have a maximum signal range of 2,000 feet in open air. This is considerably less than the advertised 2 kilometer range, but it is still very impressive for a wireless sensor. Keep this information in mind when planning your system.
