The only camera model I know this firmware will work with is the fixed-focal IPC-T5442TM-AS. I suspect it will work on other models, but it is definitely incompatible with the varifocal 5442 . This version has human/vehicle detection in the web interface, but it either doesn't work or was not yet included in the firmware. Versions up to .10.R in the V2.800.0000000 firmware thread will detect animals. This is the version that I feel is the best choice. I can't think of any reason to use this version other than to "downgrade" a camera so it will detect animals.
