What I particularly need is, to be able to adjust motion sensitivity at different levels, for different sections of viewing area.
You can do something of this by using the different types of analytics in combination, the simple motion detection, the line crossing detection, the intrusion detection.
I think the main area that's missing is general support for analytics beyond simple motion detection.
I don't think I was quite clear on that - what I meant by general support in SS was the ability to carry out a specific configured action, triggered by event notifications of several potential types, resulting from analytics in the originating sensor (camera, PIR, microphone, window switch etc), for a holistic security solution.
Even the consumer level of Hikvision cameras are able to perform various types of analytics that ideally should trigger various types of actions.
A camera doing analytics that identifies a passing number plate for example probably needs more than just an action to do some recording, maybe a lookup for example.
Surveillance Station doesn't currently handle events other than simple motion detection and video loss.
I think analytic abilities are related to processing power also.
I think you are right. The processing capability needs to match the demands of the analytic the device is performing. When it's all built into the camera or other sensor, that can be matched up well, the device is designed for that purpose.
We've seen Hikvision trimming back the processing burden with firmware updates when they over-reached the capability with multiple line crossing and intrusion detection capabilities of the 2x32 cameras.
