Wireless versus Wired Camera
While wireless cameras are easy to install and does not require running cables from the camera to the DVR, it is not advisable because:
- reliability - it is subjected to interference and the image may be too snowy to make out the details you need
- security - the image recorded by the camera is not encrypted and anyone, including potential burglars can view what is going on in your house with a similar receiver
If you intend to use a wireless camera, from the point of security, use the camera to monitor the public area rather than within the house |
