When I first had my ADT security cameras installed it worked great, for about 2 weeks. Since then, I have had nothing but camera failure on my front camera. I have had an ADT technician come out to fix my front camera, losing connection issue, for at least 3-4 times. Every time they get it running, 2 weeks later it disconnects from my WiFi. Also, this ADT app is just as bad. I was having problems connecting to the internet, using Siri on my IPhone 12 Pro, using Pandora or anything else when I am outside, or in my car. I deleted the ADT app, then everything worked on my iPhone. Before you ask…….Yes, I checked my internet and it works great. I tried rebooting my router, deleting and reinstalling the ADT app, using the WIFI extender the ADT tech put in, and relocating the extender closer to my router. It would work for at least a week or so, then the front camera stops working. Now, just like the last 4 times, I have to get the ADT tech to come back out and fix it again. The tech replaced the front camera, since it is the one camera that keeps losing connection, the last time he came out. And ADTControl causes internet problems with my iPhone. I am not impressed with ADTControl, nor my front camera.
