Complex Security Solutions receives requests for CCTV and IP video surveillance cameras, but what is the difference? Many businesses and residences still ask us for CCTV cameras but they are far inferior to using IP cameras. Security cameras come in two flavors: digital and analog. You can think of it as HDTV versus a TV with an antenna. The difference is huge. You could loose out on identifying a criminal if not using the correct cameras.

CCTV Cameras vs. IP Cameras

CCTV used to be the standard in the video surveillance industry. In the mid 1990s IP cameras started to become possible and more robust. Here are a list of reasons why analog cameras are at a disadvantage.

  1. Limited resolutions of video available
  2. Two cables required for the camera (one for power, one for video)
  3. Main processing of video signal done at the server or DVR

The worst IP surveillance camera can produce better resolutions than the best analog camera. This is due to the technology that can be built into the IP camera. For example, Axis Communications released a video explaining Zipstream Technology which produces high quality video at a low bit-rate.

The main advantages of IP cameras are:

  1. You only need to have one cable since IP cameras is PoE (Power over Ethernet)
  2. IP Cameras encode the video signal saving on processing power to the NVR (Network Video Recorder)
  3. Many IP Cameras have apps that can run on them
