It depends on how many cameras you have installed and how big the recording box is. Cameras for example use 4 watts during the day and up to 6 watts at night. The recording box meanwhile consumes anywhere between 40 to 200 watts. Your total energy consumption will also depend on how many hours per day the system is running.
These days, there are so-called “eco-friendly” CCTV security systems which are built to save energy by eliminating the need for ra recording box. These cameras have better resolution and have 360-degree coverage, so there will also be less cameras to be installed.
