Analog security camera systems are the defacto standard in video surveillance. They are simple to configure and affordable. While the picture quality in analog systems is still very good and used in many commercial security applications, due to its technical limitations, they are limited to a maximum of D1 and 960H resolutions.
Digital systems typically comprise of IP (or network) cameras connected to a Network Video Recorder (NVR). As digital systems provide complete flexibility and extremely detailed footage (HD quality), they are usually slightly more expensive than analog systems.
There are some hybrid systems (e.g. HD-SDI, HDCVI) which delivers HD video over coaxial cables which means it could work over any existing camera cabling. This would allow you to upgrade an existing camera system to HD quality without having to rewire the premises. Ask us for this if you’ve already got coaxial cables and want to upgrade to a higher resolution system.
