4.1 Encode

Encode menu allows to alter and customize how the DVR records footage and
"encodes" the files. "Encode" is a term which refers to the compression algorithm (a

Encoding Parameters (advanced user option): Whether you're editing the parameters

you don't have any audio devices connected, it's a good idea to disable audio, as it will
save some space on your HDD.
Resolution: There are three options:
