See the attached picture. You may have to really search to find if it's similar. The camera is smaller than a postage stamp. The strip is about 6-7 inches. But, it needs a power source. An outlet or, sneakier still, another electronic device such as a TV or cable box (that's where I found one plugged in.) Forgive my suspicion but I have found something like this on two separate occasions as well as other surveillance devices at other times. It seems there are enough people that are so distrustful of others they keep the market for these hidden devices going.
ELK-BLEDOM Bluetooth device shows up at seemingly random times on my phone as well. I can't "forget devive" either. Factory reset of my phone won't get rid of it. We have no strip lights nor have we ever had strip lights.
