Alarm settings

NetworKam provides flexible interfaces to cover most surveillance applications. By easy script
programming user can utilize up to four sensors with any signal pattern to monitor the environment. Users
may also use internal motion detection feature to combine with attached sensors to achieve best
surveillance. Once inputs or image variation meet the condition at real-time checking, NetworKam will
not only capture the images continuously but also e-mail or FTP to the preset e-mail address or FTP folder
and/or drive relays according to user-defined patterns. Generally the relays can be used to control alarms,
lights or door locks.
The condition script and motion detection are described in detail in the previous section. When the
condition is matched, the system will keep the intermittent captured images in memory as pre-alarm
snapshots and store the current images to the snapshots of the moment of trigged. Subsequently the
images captured at the next interval will be stored as post-alarm snapshots. The snapshots related to
occurring event will be overwritten when another event occurs. That means NetworKam will keep these
snapshots until another event occurs. Regarding to I/O event mode, it is recommended that programming
digital inputs with '\' or '/' instead of 'H' or 'L' to prevent from frequent triggers.
