Most Onvif NVRs have list their Onvif profile, and most IP cameras from reputable companies list their Onvif profile. For those of you who are bold enough to be buying directly from China, good luck returning those products to China, as Chinese Customs does not accept cameras to be returned for any reason be it warranty repair or exchange.

There’s at least an 30-60 minutes worth of testing involved per camera, after unboxing the camera(s) and properly setting IP addressing for the camera and NVR, not to mention return shipping to the warehouse if it’s not compatible on all the features you want. If the camera is a multi-sensor panoramic camera (such as the Arecont Vision SurroundVideo with more than one sensor inside the camera), will all sensors be displayed by the NVR/VMS?.If the camera is a panoramic fisheye (180-degree or 360-degree with no moving parts), then will the NVR/VMS support the de-warping of the camera’s lens, so that you can view the camera in panoramic mode instead of standard fisheye mode with the black circles around it?.If the camera supports electronic optical zoom, or Pan-Tilt-Zoom (PTZ), can the NVR/VMS control the camera’s zoom lens or PTZ mechanism?.If the camera supports on-board storage (usually a Micro SD slot), does it work with the NVR/VMS?.If the camera supports audio, does it work with the NVR/VMS?.

Does the NVR/VMS record the IPC’s stream on motion detection?.If the camera supports multiple streams, are they all detected by the NVR/VMS?.Is video displayed on the NVR/VMS in H.264, H.265, MPEG4, MJPEG, or whichever other compression streams you are trying to use from the IPC?.Although the odds of compatibility are going to be much better if the camera’s Onvif profile corresponds to that of the recorder. Can an Onvif Profile-S camera be connected to an Onvif 2.x recorder, and vice versa? It’s possible, and the only way to know for certain is to test it. And Dahua and Uniview are Onvif 2 or higher. For example, LTS/Hikvision, ACTi, and KT&C are Onvif Profile-S. It’s important to note that there are various profiles of Onvif. Onvif is a standard in the IP/Security world, which allows interoperability between IP security devices, even if they are branded differently.

If not using the same brand of NVR or IP camera, the best practice is to match each device’s corresponding Onvif profile. The same holds true for VMSes (Video Management Systems) such as Milestone XProtect, which are essentially software-based IP management systems that are designed to accommodate numerous brands of IP Cameras, with certain limitations. In some cases, the camera’s video stream might be displayed, but other features may not work. If mixing brands, or if not using a stated make and model of listed IP camera, it’s very possible that the camera’s video stream won’t display on the NVR. Unlike analog recorders, NVRs or hybrid/tribrid/multi-format DVRs (also known as XVRs) require compatible makes and models of IP cameras.For example, if using a Dahua NVR, it’s a best practice to use Dahua IP Cameras in order to guarantee compatibility between recorders and cameras. In this post, we list best practices for ensuring compatibility between IP recorders and IP cameras.
