Alarms
Video > Tamper Detect > Configure Alarms
The Configure Alarms section enables you to view the current status of the alarm output and
to set a delay for the activation/deactivation of alarm outputs.
Note: In addition to the status indication in this section, alarms can also be read from the
BC840-MC 's internal Management Information Base (MIB) using appropriate software, or
through TKH Security's Open Streaming Architecture (OSA) - that is, the "SPI API". The
BC840-MC includes SNMP support for its image monitor and tamper detect functions. A trap
is sent when bad image quality or camera tampering has been detected and another one
when the situation returns to normal. This support requires a new SNMP MIB, the OPTC-
VCA-MIB, which can be downloaded at www.tkhsecurity.com/support-files.
Item
Description
Min. event duration
Alarm output delay time: the time span that is to elapse before a
continued change in conditions actually activates/deactivates the
alarm output.
Alarm output
True or False. Indication of current status.
Tip: A PTZ camera moving from one preset to the next may trigger an alarm if the scene
change takes too long. Setting an appropriate time for the Min. event duration parameter
can delay the alarm output until the camera has adopted the new position and the alarm
condition has ceased.
