At M&J Video we get calls about Covert Cameras, also called Nanny Cameras, all the time. Nanny Cameras are hidden cameras used to watch babysitters and other help that you would hire around your house. Cameras can be hidden in all sorts of items such as smoke detectors, motion detectors, alarm clocks, and stuffed animals. They can also be hard wired or wireless. When using hard wired cameras it is best to use smoke detectors or motion detectors because the cable can be installed in the walls and ceiling, than run to a digital video recorder (DVR) hidden in a bedroom or attic. When using these types of cameras we recommend having the system installed by a trained technician. But when using wireless Nanny Cameras the installation is as esay as plugging in a clock radio. Just place it in the room that you want to view and the wireless transmitter sends a signal to a reciever that is plugged into your DVR. The information is than recorded normally as if the cameras were hard wired. When using multiable cameras you can set each camera to its own channel. These cameras will save lots of money on installation but the main drawback is distance and clear reception. Most wireless video transmitter/receivers made for indoor use have a distance rating of 100′-300′ with direct line of site. That distance is drastically reduced when the signal has to travel through walls or go from the first floor to the second floor, so there may intermittent signal loss or static in the picture. We recently did a Nanny Camera installation for a customer in Simi Valley and used a combination of both. It is working great.
