Qustion about camera streams and an SPD-152

I was in a situation with an SPE-1630, SPD-152, and a Windows-based Wisenet Server. There were 9 analog cameras connected to the SPE-1630, and three IP cameras connected to the CCTV local switch. One of the three IP cameras had two sensors.

First, I auto-connected the three IP cameras (four channels) to the SPD-152. For various reasons, I couldn't use the Wisenet protocol successfully with the analog cameras, so I manually added each one via RSTP (nine channels).

The SPD-152 would display the first 12 cameras without issue, but as soon as I'd add the 13th, all the analog cameras would stop showing on the 4x4 display. However, if I put any one camera on full screen, it would appear properly.

Here's where I started getting really confused: when the Wave Server shutdown for Windows Updates, all 13 cameras suddenly displayed properly on the SPD-152. The technician said that it had something to do with requesting too many streams from the cameras, but I didn't quite understand what he was saying.

Either way, I decided to turn off the second stream on a few of the analog cameras and then everything worked properly, even with the Wave Server online.

Would someone mind explaining what was happening in this scenario? What was the issue involving camera streams? Was I trying to display too high of a combined resolution when I had 13 cameras on a single screen? Any other variables that I am not aware of?

Thanks!

  Hi Daniel,

  Thank you for your request.

  Based on what you mentioned in your request and what the technician advised makes sense.

  Based on the manufacturer of the cameras and encoder there are limitations as to how many streams that the cameras and encoder will provide.

  Just as an example our Q series cameras can have up to 6 profiles and 3 concurrent streams so if you are using Wave as well as a decoder then this will consume all three streams so if a fourth is requested one of the recipients will lose access to that stream.

  Hence why when you stopped Wave that automatically requests two streams from the camera a primary and secondary stream so that is two already in use. If the decoder is requesting a further two then one recipient will experience transmission issues.

  Now with higher quality cameras like our X & P series cameras we can have 10 profiles and up to 6 concurrent streams so this wouldn't be an issue providing streams to both Wave and  the decoder.

  Looking at the encoder it is limited to 3 profiles per analogue camera so that would explain why you are experiencing this limitation.   

  As for the Wisenet profile not working that is only designed for Hanwha devices but if you are trying to enroll the encoder a multi channel option under the Wisenet option as shown below.
