Bought this on Ebay, it's an unbranded Dahua / Alhua 6MP turret camera. This is the closest I can find on the web site: https://www.dahuasecurity.com/products/ ... 4631EM-ASE
The camera firmware viewer requires some ActiveX plugin, I didn't bother. But the settings tab works.
Works out of the box with Zoneminder 1.34. Settings:
General:
Source Type: Ffmpeg

Method: TCP

Target colorspace: 32 bit
Capture Resolution (pixels): 1920x1080*
*I have the resolution in the camera firmware set to 3072 x 2048, Zoneminder set to 1920 x 1080. This produces a good image. It also works with Zoneminder set to 3072 x 2048. Setting the camera firmware to 1920 x 1080 produced a horribly grainy image.
