Cable clutter compared to proper cable laying - perfect permanent, stable solution
1. IP video cameras always have better picture quality than analog video cameras (BNC), based on chip technology.
2. The installation of an IP video camera system (as we only have it) is much easier than that of the BNC analog video camera systems.
3. The laying of the video cables of a BNC analog video system is in our opinion a pure "cable spaghetti", because all video cables (eg with 8 cameras) have to be laid directly from the back of the DVR - you have a whole tree trunk on the back of the DVR hang. Compared to the IP video system, you can work with a network switch. This means that you initially only have one network cable from the DVR to the network switch (video distributor) - a very clean and simple solution.
Onvif protocol: third party and the restriction
1. Yes, usually a third-party camera can be integrated, but with restrictions. Third-party cameras must have the ONVIF protocol. As a rule, almost all cameras have this. However, it does not mean that a third-party camera with ONVIF 100% is recognized, since each manufacturer still uses its own internal, unpublished protocols and other Onvif versions are used again and again. It can only be tried.
2. No, in most cases the motion detection and / or PTZ control is not supported, only the video stream.
3. No, regardless of the recording device, you will encounter the same problem everywhere. But usually you can at least integrate the live stream of the third-party camera - if only with limited Funktions.
