Surveillance Video Forum

Hi All:

I am about to order a DVR from surveillance-video.com and I need clarification on one thing:

I want the highest quality recordings possible and a I need an 8 channel DVR.

Is 30 fps (per camera) the highest rate out there? So if an 8 channel DVR boasts 240 fps I gather that's 240 / 8 = 30 fps per camera.

Does this mean that a 16 channel DVR that boasts 480 fps (480 / 16 = 30 fps per camera) would render 60 fps per camera if only 8 of the 16 inputs were used? If so, would the picture quality be any better than 30 fps?

Should I also be considering resolution (eg: 720 x 420)?

Thanks.

Hi BobKat,

Yes, 30FPS per camera is the highest possible frame rate available. We find this frame rate to be more than enough in most applications. Obviously if recording time was not a concern than recording at full frame rate is the best thing to do. However doing so will increase the file size of the recorded video and as a result you will use your hard drive capacity a lot faster, so we suggest playing around with the frame rate and weaken it down when possible in order to get longer recording time.
The maximum amount of frame rate that you can get on the recorders included with the systems is 30FPS. Even if the total recorder frame rate is much higher you can not allocate more than 30 frames per second per channel.
