Can you fix pixelated videos?

The compression makes video files smaller, cutting memory usage, but too much compression hurts the video quality. After this data is gone you can’t get it back.

How to avoid voltage drop on CCTV systems?
If you are using the cable to power a camera as well as transfer video signal then we recommend a maximum distance of about 50 meters (200 ft) to avoid voltage drop. This assumes you are using 3 pairs of wire for 12 volt supply and 1 pair for video signal transfer.
