We are out of contract with ADT and I'd like to get my alarm monitored and maintained by somebody who actually knows what they are doing. e.g. last maintenance thing it was compaining about a low battery in one of the movement sensors. They replaced the battery. Now its complaining about the other 2 being low. Wouldn't you have thought that as these things all get used together, all went in together etc that when one is low, that the others will be pretty low also. I suspect that they were banking on me paying for another call out and the charge that they put on to it.
