Now I wanted to secure the window. They are with us 16 of them. But since I could read some unhappy customers here, I ordered only used. 4
Conclusion: The first four "window" sensors could install cumbersome after several attempts. After a few days, a sensor gave up the ghost. All attempts to integrate it into the new system, came to nothing. I want to trade him. For a time, was deceptive calm and I ordered the remaining sensors after. But it was not long until the first sensors lost contact with the base station. Every now and then you had to integrate them anew. This really is very annoying, because my life is limited.
Now I list again a complete failure of a sensor. Unfortunately, the return period has expired. Now it only remains the legal guarantee, which engages within the first 6 months. I'll report on how they handled them. Currently showing me to the system that 7 out of 10 sensors "ambiguous" are. I mean, I have to readjust all again !!! One has no more connection! Only the siren, the door sensors and motion detectors to run like clockwork. After 3 months me a door sensor says, however, know that the battery should be replaced. This is a weak running performance.
I'll replace the system by another medium. Then it here some cheap used equipment be on sale.
