DSC WLS922L-433 - Wireless Acuity Glassbreak Detector Reviews
Submitted on 01/16/2020 Alarm Grid
The DSC WLS922L-433 is a 433 MHz glass break sensor that monitors windows and protective glass casings for glass break events. Sensors like this one are very commonly used in residential locations, as well as businesses like gun shops and jewelry stores. What's great about this sensor is that it can monitor multiple windows and/or protective glass casings using its high-performance microphone. Overall, this is a very nice wireless glass break sensor that we would recommend to anyone with a 433 MHz security system. It gets a 5-Star rating from us.
There are many things we like about the DSC WLS922L-433. For starters, its high-performance microphone works great in listening for glass break events, such as a window being broken or a product display case being smashed. This microphone helps the sensor actively distinguish between true glass break events and potential false alarms. Since the device uses digital signal processing, it can work well with nearly any type of glass. This includes plate glass, float glass, tempered glass, wired glass, and laminated glass. We also like the fact that the sensor has a dip switch that allows the user to choose between high and low sensitivity options. Overall, we have found that the DSC WLS922L-433 reliably responds to glass break events, while also not being set off by similar sounds that could otherwise cause false alarms.
There are not many downsides associated with the DSC WLS922L-433. The biggest problem is that the device needs a direct line of sight to the windows and/or casings that it is monitoring. Needing a direct line of sight is fairly standard for a glass break sensor, but it is still something to keep in mind. Also, since the device is wireless, it will require periodic battery replacements. In most cases, the batteries will need to be replaced every three (3) to five (5) years. But these downsides are relatively minor, and they do not stop us from giving this product 5 Stars.
Good: High-Performance Microphone, Prevents False Alarms, Reliably Responds to Glass Break Events, Digital Signal Processing, Works w/ Most Types of Glass, Dip Switch Sensitivity
Bad: Needs Direct Line of Sight, Battery Replacements Needed
Bottom Line: 5 Stars
