Odd behavior with IP cameras

[amani 0]

At 5 sites we have old Pelco cameras and at 2 sites we have new Axis cameras. There are 5 cameras at each site, and all the cameras are connected to a Axis video server.

 

All our cameras set to record 1 fps, and if you view the camera directly you can see that it is showing you 1 fps.

 

Here is where things really get odd. We use an outside vendor to record all our cameras. If I go to their website, and bring up 1 camera, say a fixed camera, I see video in real-time and bandwidth shoots through the roof (> 90% utilization).

 

We were thinking of bringing our video recording in-house, but now that we see two different types of behavior from our cameras we can't be sure of our bandwidth requirement.

 

I would appreciate any thoughts on why video directly from the camera is different from the video we see through our vendor.

The cameras have different streams. In house your viewing the stream set at 1 FPS. Your MvaaS provider is viewing a different stream set at a higher bit rate.

 

If you go in house with a NVR and VMS you can connect and record at 1 FPS if you like.

Thank you for the reply. I checked the AXIS 243Q Blade Video Server for one specific camera. Under Image Settings > Video Stream, I see Limited to 1 fps per viewer.

 

My understanding is that every viewer should be limited to 1 fps, but that doesn't seem to be the case.

Do a local test record.

After talking with Axis yesterday, I did learn something. If they (our MvaaS provider) are using API's that means they are using commands to pull streams. These are separate from what is set in the camera. The API commands contain stream parameters that may very well differ and be higher than what you are setting in the camera.
