Choosing a system
If you're looking to installing a new CCTV system, we would recommend to have it IP based;
Essentially cameras and recorder all sit on your IT Network just like a Computer.
If you already have an existing CCTV system but are looking to modify the cameras, we would look to install an AHD (Analogue) Camera System.
Both systems would be viewable by PC, mobiles
and tablets are would be run off a separate set-up in order to only allow authorised users to control and view the material.
