1.2GHz 380 TV Lines 4 LEDs Wireless Camera ES202cwsa

Wireless Cameras come all shapes and sizes and are capable of transmitting to different distances. The transmission range of a Wireless Camera is usually rated by use the Line-of-Sight (LOS). Standard Wireless Video Cameras have a range of about 700 feet LOS. The signal can be transmitted through most solid objects including glass, plastic, wood, fiberglass, and some metals, but the signal is attenuated. So the actual transmission range depends on the number and type of objects you are transmitting through, such as brick walls, concrete walls, trees, etc. An ordinary 700 ft. LOS Covert Camera can typically transmit signal through about 6 interior walls with ranges up to 200 feet and is designed to work comfortably in a building up to 6,000 square foot (home or office).

An ordinary Wireless Camera transmits its A/V data via RCA or COAX cable to a monitor or a recording device (either a VCR or DVR). If you want to view this data remotely, you would need to purchase a special kind of DVR that converts the image data to digital output, and has networking software to broadcast this digital data over a network.
Also called "IP Cameras" or "Ethernet Cameras," a Wireless Network Camera transmits its Audio/Video (A/V) signal via standard computer networking CAT5 cable. It has software built-in on its chip that allows anyone on the network to view the A/V data, just like a computer on a network. There is no special software needed to view the camera. You can view the images in an internet browser by pulling up the IP Address assigned to the camera. To record the video, you can use software such as ReCam - Network Camera Monitoring Software on any computer on the network.

The signal generated by a 1.2GHz Wireless Camera may be (but not always) disrupted by the 1.2GHz cordless phone or other 1.2 GHz devices. If you are not sure whether or not your cordless phone or any other 1.2 GHz system in your home or office interferes the wireless camera (cannot get good video signal), unplug power to your phone etc. to determine if that is the problem.
Your microwave oven might also generate a conflicting signal; your Wireless Video Camera and the microwave oven operate on the same frequency. This will not damage your camera.
