The first thing that you should consider is whether you need digital or analogue CCTV surveillance cameras. Which of the two do you need? These two have different ways in recording videos. Digital CCTV surveillance cameras are capable of creating files and then storing it to an internal memory card or hard disk while analogue cameras uses VHS recorder, which means that you will need lots of blank tapes. Analogue cameras are limited when it comes to recording videos, so if you are concerned about unlimited recording, then you should choose digital CCTV security cameras.
