Good Door & Window Sensor
Submitted on 05/14/2020 Alarm Grid

The DSC WS4945 is a wireless door and window contact sensor that operates at 433 MHz. This makes it compatible with systems like the DSC Impassa, the DSC PowerSeries Panels (wireless receiver required), and the 433 MHz Qolsys IQ Panel 2 Plus. This is a fairly nondescript door and window sensor, but it certainly gets the job done. It is easy to use, and it has relatively few downsides and drawbacks. For that reason, we give the DSC WS4945 a 5 Star rating.

There are many things we like about the DSC WS4945. For one, it is easy to install and use. The maximum allowed magnet spacing gap is 5/8 of an inch, which is pretty decent. The sensor has a slim profile that allows it to fit neatly into tight spaces. You can mount the sensor using double-sided foam tape, or you can use traditional mounting hardware. The sensor has a tamper switch, and it will alert the system whenever someone tries to open up or disable the sensor. The device also has a pretty long battery life, as you should only expect to make battery replacements every five (5) to eight (8) years. We also like the fact that the sensor has an auxiliary input for a Normally Closed wired contact.

But there are some downsides to the DSC WS4945 that should also be considered. While the sensor has a slim profile, it is still a somewhat bulky and dated design. Most users will prefer the more compact VERSA-DSC Door and Window Sensor, which is more attractive and will accomplishes the same thing. And although the DSC WS4945 has a long battery lifespan, it uses a lithium CR2 battery, which is somewhat uncommon. But these downsides are relatively minor, and they do not stop us from giving the DSC WS4945 a 5 Star score.

Good: Easy to Use & Install, 5/8" Magnet Spacing, Slim Profile, Multiple Mounting Options, Tamper Switch, Long Battery Life, Auxiliary Input

Bad: Bulky, Dated Design, Uses CR2 Battery

Bottom Line: 5 Stars
