GV 1480 and camera video lines (resolution)

[cyboyeee 0]

I have a 1480 and I am planning on upgrading some cameras in my home outside surveillance system. Cameras have different lines of resoultion like 520, 480, etc as you know. (and I know resolution is the improper term here) What I need to know is if I get a 520 line camera will there be any difference in recording quality when using the highest quality compression codec (I believe somebody said MPEG4 was) versus a 480 line camera?

What I have found is that the determining factor for max quality of camera, whatever the res, is the Screen resolution you set for display.

 

The H264 is the highest compression you can use in later versions, so if you are in the 7.0 region of software, its not available.

 

Setting res to 720x480 area should allow you to get the max quality from your cameras. The mixing of different resloution cameras isnt a factor.

Did you mean to say the H264 is the highest Quality compression? Or that it can compress the most?

 

I have the 8.0 software, fyi.

 

Thanks!

That statement would be incorrect, H264 is a lossy compression and not a Lossles compression, therefore it isnt the BEST compression, you wont see much difference between 480 and 550TVL

Ok, then what compression or file format would give me the best quality image?

using GeoVision and version 8.12, Geo Mpeg4.

 

You can also separately set the webcam and other network modules to use H.264 if you have slow internet connections, but using that compression, quality would be drastically reduced within those modules.
