Hang it on your bedroom ceiling or in the kitchen, the Smoke Detector Wired Hidden Spy Camera System blends in anywhere you would normally place a smoke detector. It won’t detect smoke, but it will detect what’s going on in your house when you’re not there. So, please be sure you don’t use it to replace your already existing smoke detector, because it only functions as a camera. Like all of our wired cameras, This wired camera connects to a TV, DVR , Camcorder or any VCR for easy viewing and recording. Less than 5 minutes to set up (not including any extra time needed to conceal the cables), this wired camera system is still pretty easy to install. But before you order a hidden camera spy system with wires, just make sure you’ll be able to make the cords completely undetectable. It's perfect for situations where you need a more permanent observation system
