Due to some recent burglaries in the neighborhood I decided it was time to put in some kind of security system. I thought I had found a wireless system that on the surface sounded pretty good. It cited full house coverage with up to 32 or so wireless window/door sensors, plus a motion detector, and lamp flasher. Also stated the built in "siren" was as loud as a full volume stereo system. $200 for the "system"
I installed 11 of the window/door sensors and the motion detector. My house is two story and all the sensors were on the first floor within about 20' of the centrally located main control box. I had trouble with one sensor mounted to a metal door. The door evidently shielded the signal, as well as a sensor that was located on a window behind an LCD TV. Tried moving main box and different orientations. Got things sort of working, but every time I wanted to arm the system when leaving the house, one of the other sensors would develop a "problem" and needed a reset to be able to arm the system, which was a real PIA. After having the system better than a month other sensors began to develop issues. The "siren" that was supposed to be louder than a full volume stereo was actually not as loud as a battery operated smoke alarm, hardly enough to scare off a would be burglar if he could even hear it. I hadn't hooked up the phone dialing system for fear it would be a problem with possible false alarms. The system didn't come close to functioning as the online description purported. This forum suggests modifications of the system to "improve" operability. Having to modify something that should work out of the box doesn't say much for the equipment and not worth the effort.
Everything I subsequently read about the company selling this POS was extremely poor customer service and bad product. Unfortunately I bought on recommendation from someone and didn't do my own research. Lesson learned.
Today I removed the whole system and it hit the trash dumpster. Big waste of $200. I thought about ebaying the stuff to recoup some of the money spent, but I have yet to sell junk on ebay and I won't start now.
I'll finish installing the hardwire alarm system I had started prior to purchasing this.
