5. exit passageway indicator light operating status certifying organization as claimed in claim 4, it is characterised in that:
In alarm triggering equipment, it is also used to when the live mean square deviation numerical value and the scene mean square deviation values match
When, it issues and shifts signal unconfirmed.
6. exit passageway indicator light operating status certifying organization as claimed in claim 5, it is characterised in that:
In the automatic processing equipment, the dynamic range of the image to be processed is wider, executes spy to the image to be processed
The intensity of sign in-depth processing is smaller.
7. the exit passageway indicator light operating status certifying organization as described in claim 1-6 is any, it is characterised in that:
It makes video recording in mechanism at the scene, including memory capacity detection device and storage card, the storage card is used for described existing
Field make video recording mechanism acquisition multiframe continuous in time exit passageway portal image storage；
Wherein, the memory capacity detection device is connect with the storage card, can for measuring the current residue of the storage card
Memory capacity.
