So like a many others on here, before I can make any guarantees about whether or not the quality can be increased, I'll need to see the video. Often times security of CCTV cameras shoot at such a low resolution in order to save space, that there's no saving or enhancing the video. That being said, once I see the video if it is savable I have several tricks at my disposal I can look at to see what I can do for you.
