Some things that matter when it comes to configuring your IP Cameras (Beyond security, etc): - Support for RTSP - Configurable Encoding Settings (e.g. h264 coded, bitrate, i-frame intervals, framerate) - Support for Substreams (i.e. a full-resolution main stream for recording, and at least one lower-resolution substream for preview/detection/etc) ...
Make sure the hardware you select is capable of the above.
Configurability will matter because Identification is not the same as Detection (Reference: "DORI" - Detection, Observation, Recognition, and Identification from IEC EN62676-4). If you want to be able to successfully identify objects or entities using your cameras, it will require more care than basic Observation or Detection.
