Someone put a spy camera inside my TV and the guests called the cops. By the time I arrived, the cops were already dismantling the TV. When they removed the back panel there was a lot of space enough to put a USB power supply, a tiny transmitter, antenna and a tiny camera poking right above the remote control receiver. The guests saw blinking blue light. In shock -- cops said they will be back and I should not enter that property. The guests then left. Since I couldn't sleep, I looked up ways to prevent it. If the internet company allows you to have your own DHCP server, then buy an expensive router that lets you upload and backup all DHCP logs. Then you can run custom scripts to see if a new device is constantly on your network. Guests typically stay only for a few days. So what is this new device? In my case, the dhcp server is on the modem given to me by the internet company and I cannot configure anything. Cops will have to contact the Internet company and find out if they can tell us when this this supply device first came online. On the 25th of November last year a guest complained that the TV fell off because it was held by one screw. This was obviously a lie because I had four screws on stud and there's no way a lightweight modern TV which probably weighs 15 lb will fall off. I think he took it down. Put the camera in. But could not put it back at the original spot because it was very high up. So he put it up down low and spun up the light to cover his tracks. If he had been able to put it at the original spot he would not have messaged me See less
