I purchased a IP Camera PoE. I have it connected and I can log in but I'd like to update the firmware. Its currently at: Software Version 2.400.0000.30.R, Build Date: 2016-06-04 WEB Version 220.127.116.110858 ONVIF Version 2.4.2 So I decide to google the model online and find the latest firmware. Well this model doesn't even show up on searches! On the box and on the underside of the camera, the model shown is IP-784IR-WZ. Searching this model doesn't show any Dahua cameras. Now the guy I purchased it from also provided me with a data sheet which I've attached. It seems its a rebranded camera. From the specs, I believe its a IPC-HDBW5431E-Z. But when I try upgrading any firmware that is supposed to be for this camera, it fails (both via browser and via configtool). The config tool just says "upgrade failed" after getting to 50%. On the browser, it says "File unmatch". I tried the following firmwares: DH_IPC-HX5X3X-Rhea_EngSpnFrn_N_Stream3_V2.622.0000000.31.R.180813 General_IPC-HX5X3X-Rhea_Eng_P_Stream3_V2.622.0000000.18.R.20171110 DH_IPC-HX5X3X-Rhea_Eng_P_Stream3_V2.460.0000.10.R.20170523.bin Would anyone know how I could find the firmware that I can upgrade this camera? Is there a way to confirm if this rebranded model actually maps to the IPC-HDBW5431E-Z? Is there a RS232 or some way I can telnet into the camera and see additional hardware info?
