SNMP Traps
A TC620-PID alarm status change generates a trap which can be caught by any SNMP manager.
The TC620-PID can, for example, send traps on the occurrence of Image Quality and Camera
Tampering events. Variables, which can be read from the TC620-PID's MIB through an SNMP
manager, indicate why the alarm occurred. The OPTC-VCA-MIB required for this can be
downloaded, together with the other TC620-PID MIBs, at www.siqura.com.
