Abstract
Video surveillance systems have special requirements with respect to networking and remote access functionality. Conventional communication links do not necessarily meet these requirements. Power line channels, accessible via power line modems, do, in some cases, meet the requirements of video surveillance systems where conventional communication links do not. The present invention provides a flexible and reliable video surveillance system that includes networking and remote access capabilities employing power line communication channels.
Claims15
A surveillance network node comprising:
- (a) a power line modem;
- (b) a second modem;
- (c) a switching means for selecting one of the power line modem and the second modem for a transmission of surveillance information;
- and
- (d) a computer usable medium having computer readable code means embodied therein for signalling the switching means to select one of the power line modem and the second modem for transmission of surveillance information.
A method of operating a surveillance network node comprising:
- (a) measuring a parameter related to one of surveillance source information, channel information and client preferences;
- and
- (b) changing an operating parameter of the surveillance network node based on the measured parameter.
A networked surveillance system comprising:
- (a) a plurality of surveillance network nodes each having a power line modem, a second modem, a switching means for selecting one of the power line modem and the second modem for a transmission of surveillance information and a controller for signalling the switching means to select one of the power line modem and the second modem;
- and
- (b) a client device configured to access surveillance information collected and transmitted by at least one of the surveillance network nodes.
