Hi,
I'm looking for a cheap cam (3-4MP, preferably bullet cams) with varifocal motorized lens (e.g. 2.7mm ~13.5mm) + audio (built-in mic or/and external source w/ AAC compression). I've searched on dahua's website, but they only sell newer cameras which are over $100. There's a few cheap cams on ebay and aliexpress but there's inconsistency in the tech specifications. I've only found the IPC-HFW4433F-ZSA whose -ZSA suffix would suggest that it has both features + SD card support. Where can I find a user manual for it?
And what about the PC-HFW4431R-Z? Does anyone know if it has audio input?
