Introduction
Have you ever wished that your budget friendly day-only cameras
could detect intrusions even in total darkness and make the intruder
clearly visible for video evidence recording? Now it is possible! All
the ACTi cube cameras come with built-in passive infrared
sensor (PIR) and with the terminal block for digital input and
digital output (DI/DO).
The built-in passive infrared sensor detects human movement by
sensing temperature changes over the scene, and works even in the total darkness. Human
body heat moving across the scene will trigger PIR sensor. The alarm signal will be sent to the
control center over the IP network instantly. As the digital output of the camera can be
connected to external lamps or alarm sirens, these devices will be instantly activated upon
the detected motion. As a result, the intruder who entered the guarded area in total darkness
will instantly be exposed for high quality video shooting.
In other words, instead of trying so hard to adapt the camera to poor lighting conditions
which quite often is a costly solution, you can simply turn the night into day when the
alarm is triggered and benefit from the best possible video quality in color mode!

  • Page 11 Although the PIR setup via NVR is very simple and convenient, there may be users who might prefer setting up PIR using firmware interface of the camera instead. Besides, ACTi firmware contains powerful Event Handler that can be used as an independent system to maintain the events and the responses directly inside the camera without needing any NVR support.

  • Page 23 FIRMWARE VERSIONS AND FUNCTIONS Firmware containing Event Handler is available for ACM-4201 and ACM-4001 already today. The TCM-4201 and TCM-4001 would require firmware version v4.09.xx that contains Event Handler. Expected release date of v4.09.xx is December 2010. Customers who have already purchased the TCM-series PIR supported cube cameras can enjoy the benefits of Event Handler through firmware upgrade in the camera sit, for free.
