EV-DW4975 | Vanishing Wireless Door Window Sensor

Who wants something bulky, unsightly and difficult to install?

Most Windows Sensors are hardwired and require either costly professional installations or a frustrating trial-and-error process. Not so with DSC's Vanishing Wireless Door Window Sensor, as its wireless capabilities allow the unit to simply be mounted within your chosen door or window frame using the supplied double strick tape or screws, sending an entirely wireless signal to the receiver of your choice when an intruder attempts to make an unannounced visit.

This is simply the thinnest window sensor on the market today and can be concealed easily within any window or door frame of any size, which means that intruders will not only be easily detected, but they'll never see it coming. The EV-DW4975 uses a replaceable lithium battery and should last 5 years under normal usage.

I installed three of these in my house. They were very easy to enroll in the wireless keypad I have (RFK5501). I have had one error with one of them already (failure to communicate). I am hoping it was just a fluke. If I don't have anymore problems in the near future I am going to be ordering four more.

I've had 9 of these on my system for going on 4 years. Long battery life, strong magnets, easy to install, and quick response. Have had 1 false alarm in 4 years. Can't complain at all.

This is a great wireless contact for any wirless DSC system. The magnet appears to be very strong (rare earth?) and can bridge wider gaps. The battery (CR2032) is also less expensive and easier to find than most other batteries at a variety of stores. The contact is almost unnoticeable.

This contact is not noticeable when installed. However, I have had several false alarms due to this device not registering the zone closing. Maybe I just have a dudd...

I bought one of these to replace a broken older model. It's so much better than the old ones. It is slimmer by far and appears to be interchangeable if you need to put it on a door or window. It takes a 2032 coin type battery which is so much cheaper and easy to find than the 2450 type needed by the others. It is a good step up from the model it replaces.

A great product--would have been 5 out of 5 if they were a little cheaper, but for what you get, it is a good deal. It is amazing how something so small can do what it does, and without any false alarms (so far).

I was very surprised at the size of the sensor and magnet and was thinking theres no way this will work. Oh was I wrong! If your looking for a very small sensor that will be unoticed, then this is it. Very pleased with the product and as usual, the Technical support with programming assistance.

Based on the pictures I was expecting this to be a few inches long - the magnet is about 1 inch and the sensor about 1.5 inches - tiny! Each to setup and install, just be careful, it's so small and thin that it feels somewhat delicate.
