4K POE IP Fisheye Camera, Mic. Audio in, 1.7mm Lens, 49ft Infrared, WDR, Metal housing, IP66 Water-Proof Indoor&Outdoor Panoramic Security Camera(Compatible with Hikvision/Dahua NVRs)

Picture wasn’t too bad. But Iuse it with a Hikvision NVR and it’s working but won’t clear up on sub stream. It’s showing blurry (lightly)

Product died in less than 2 years

NEGATIVES: I purchased it to work with my Duhua-equivalent NVR. The set-up wasn't exactly easy, but I did get it working. In doing so, I realized that it only works with the NVR using the ONVIF protocol. I was expecting it to would work with the Duhua NVR protocol (port 35000/37777). Because it doesn't, I had to do some network 'tweaking' to get the camera to sync time properly (my cameras are on a private/closed network). The real issue with using ONVIF versus the Duhua protocol comes into play with recording video. The camera's recording does not properly sync up with the other Duhua protocol-based cameras and the recorded video is constantly dropping out. I don't believe this can be attributed to network congestion issues because, as I stated previously, it's on a private/closed camera-only network. The other cameras don't have this problem. I wish this camera ACTUALLY supports Duhua NVRs, as the description states. If their 'support' of the Duhua NVR is only through the ONVIF protocol, then the description should state it supports ONVIF NVRs and drop any references to Duhua, specifically. Many, many other NVRs also support ONVIF but they don't bother listing those. This is false advertisement in my opinion. POSITIVES: The camera looks feels solidly built and I like that it has a more unobtrusive appearance than a bullet or other type of a camera. It has been performing solidly when only streaming (not recording) video. I haven't noticed any significant drop-outs or freezes. And, time is syncing just fine with the other cameras once I made the 'tweaks' to my network.

While installing my Vonnision 4K fisheye camera, it accidentally fell 10 feet to the floor. Surprisingly, the camera was mostly undamaged; it seems to work fine when hooked up, but the glass cover over one of the IR lamps shattered. I'd like to get a replacement glass cover, and I have searched online for Vonnison, but can’t find any way to contact them; the closest I found was Vonihome, but they do not list this specific camera.
