1. Resolution: An analogue camera of 540TVL equates to about 0.4 MP, whereas a standard IP camera of 2 MP, can give over 5 times that resolution. With some IP cameras ranging up to 10MP, it’s easy to see how the technology can cut down on the overall number of cameras required. A typical example would be replacing PTZs on a garage forecourt with one IP/Megapixel camera.
2. Remote Access: You can login into a secure server remotely, using a web-based interface, to view real-time footage on PCs or Macs, as well as mobile devices such as the iPhone, iPad, and Android. Programs such as TeamViewer also allow for remote support and end-user training.
3. Analytics: The dramatic improvements in hardware have been matched by powerful Analytics Software. Video Management Systems (VMS) can be combined with other software to allow for applications such as license plate recognition, people counting, and motion detection.
4. Power: IP cameras utilise Ethernet cables which allow for Power over Ethernet (PoE), meaning only one cable per camera is required, to carry both power and data
5. Hybrid: High end Network Video Recorders (NVRs), such as the Minotaur Server, allow existing CCTV cameras to be incorporated into the IP system. This can significantly reduce the initial costs, and allow a phased approach towards a complete IP Surveillance solution.
6. Scalability: Utilising edge processing, and individual camera licencing, it is possible to scale from a single camera up to thousands.
7. Redundancy: It is possible to record simultaneously to a Network Video Recorder (NVR), and a SD card installed locally on the IP camera. This offers an additional safety net to recover footage in the event of damage/corruption to data on the main NVR.
8. Lossless Playback: Footage can be reviewed with multiple zoom on playback, even on fixed lens cameras, with no degradation of the image. This alleviates a common problem with analogue systems, where high levels of compression can often leave the image unreadable
