It's Sleek, it Blends and it's Effective.

This Vanishing Wireless Door and Window Sensor is a must if you want to increase your security and stay discreet about it at the same time. It works with most DSC wireless alarm systems.

Just like that, your home security system gets an upgrade. The lithium battery usually lasts 5 years under normal usage and its rare earth magnet keeps the sensor free from failure.

The beauty is, it's so small and compact that even an experienced burglar can't spot it. Increase your security and keep your home beautiful with DSC's Vanishing Wireless Door/Window Sensor.

Really like these transmitters! They were really easy to set up and super responsive. The magnet activates the reed switch from a pretty good distance, so they dont have to be right next to one another. Perfect for people who have trim that forces them to have more distance apart. Will buy more!

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.
