LINKLOCK options are available in Veracity’s high performance HIGHWIRE Powerstar Base 4 and Base 8 Ethernet and POE over coax devices. LINKLOCK™ detects any disconnection/reconnection or tampering with any part of the cabling between the Base unit and the IP camera or other POE device. Any externally mounted IP cameras potentially leave an exposed network connection which could be used by attackers to access the rest of the network - to disable the surveillance system for example. This may also expose the corporate network as this is often bridged to the surveillance network. LINKLOCK prevents such attacks by completely disconnecting power and data for that channel whenever it detects a cable disconnection or reconnection or even any tampering such as “tapping in” to the coax or network cables. LINKLOCK works by constantly monitoring the POE power connection and data transmissions. It can detect even subtle changes or interruptions in the data transmission characteristics which will trigger disconnection and alarm, whilst remaining extremely robust against false alarms. Once triggered and disconnected, the channel can be re-established via the reset pins after suitable action is taken to determine the cause of the alarm (i.e. a possible attacker). LINKLOCK™ is available as an option on Veracity’s HIGHWIRE Powerstar Base 4 and Base 8 models of Ethernet and POE over coax adaptors. The Base unit accepts external power via a POE switch or a DC power supply. It sends power over the coax link to the Camera unit. The camera unit in turn provides POE (Power-overEthernet) to the IP camera. See HIGHWIRE Powerstar Base 4 or Base 8 datasheets for full information on HIGHWIRE.
