Question: 

What is the difference between h.264 and h.265?



Answer:

H.265 will encoding will result in smaller file sizes which will allow you to record more footage, but at the cost of taking more resources from the recorder to process, which in turn may mean you cannot stream as well depending on your network. H.264 will create larger files, but take less resources from the recorder so it is advisable to use this if you are seeing performance or network issues.
