Long Distance 2.4GHz Wireless CMOS Camera C-501

A wired camera needs a cable that goes from the camera to a TV, VCR or DVR. The video signal is passed from the camera, through the cable, and to your TV, VCR or DVR which allows you to see the picture. All wired cameras must use RCA/BNC cable to connect the camera to the TV, VCR or DVR. For example, a clock radio hidden camera will plug into the wall just like a normal clock radio. The camera transmitter hidden inside the radio is powered by the clock radio's power supply, which requires plugging the AC cord. Another example, a smoke detector hidden camera will have to have an external power source, so the AC cord needs to be transferred through a wall or ceiling in order to power the smoke detector camera.

A wireless camera does not need an RCA/BNC cable connected from the camera to the TV, VCR or DVR. That is the main advantage, without spending for any extra expensive wiring. The video signal is transmitted through the air to the receiver directly. However, wireless cameras still require power. So, either a power adapter or batteries must be used.

Wireless means there is no video cable running from the wireless camera to your TV, VCR, or DVR. For outside applications, wireless means no wires stretched across your home between the wireless hidden camera and the receiver. All wireless cameras still require a power source regardless of whether it is an indoor camera or an outdoor wireless camera. A wireless receiver must always accompany a wireless camera. Also, a receiver must connect to your TV, VCR or DVR with A/V cables and requires a power source too. Thus, a wireless camera only eliminates any wires stretched across a room or outdoor location to a house.

Yes, you can use a 1.2GHz wireless camera in other countries, but not in the USA and Canada, as it is restricted by the FCC.
