IP (Internet Protocol) Camera is a type of digital video surveillance system that receives control data and transmits image data via the Internet. The cameras are normally connected to an NVR (Network Video Recorder) via a network cable or a wireless connection (centralised system) or record data on a local SD cards (decentralised system).
IP systems are technologically more sophisticated, more easily scalable and easy to set up, which is why they are increasingly replacing their analogue CCTV counterparts.
Why Choose an IP System?
Remote Viewing – you can access wherever you are via the Internet
Resolution – including now affordable 4k IP cameras
Remote control – alarm / control management + two-way communication
Easy installation – suitable for DIY installation
PTZ – Pan, Tilt, Zoom control
VCA – Video Content Analytics (motion detection, cross lining, plate recognition etc.)
Power over Ethernet (PoE) – supply power through the ethernet cable and operate without a dedicated power supply
What disadvantages IP camera have?!
Higher (per unit) cost – individually IP cameras may be more expensive than analogue CCTV
Digital vulnerability – as the video is transmitted over the public internet rather than a private network or intranet, the system potentially becomes open to a wider audience including hackers.
All things considered. IP cameras provide quality, comfort and safety – and are the way to go!
In our next post we will look at different types of IP cameras and things to look out for.
