IP Camera Systems – What Are They?

What exactly is an IP Camera System?


On the 15th and 16th of September 2016 three Senior Design Surveyors from Crime Prevention Services, Dan Farrell, Dave Evans and John Ayre, attended a 2 day National IP Experience Partner Event at The Dell Innovation Centre in Limerick Southern Ireland .

The seminar was specifically organised to present the latest Dell and Intel technologies, in addition to the very latest IP CCTV System storage systems, networks and IP cameras and giving those who attended a greater understanding of all the advances in IP technology.

What is IP?

IP based camera systems are undoubtedly the future, they work by turning real time images and audio into data which is then transmitted as data over a network or internet connection. The ultimate benefit of this over analogue CCTV systems is greater flexibility, infinitely better performance and easier installation.

IP systems have no theoretical limit to resolution, providing there is sufficient internet/network bandwidth to transmit the images. IP cameras offer especially high detail precision with megapixel resolution and at least 3 x higher quality than standard analogue cameras.

IP systems do not require local recording, they can transmit their images across local networks, the internet and wide area networks.

IP cameras differ from previous generation analogue cameras, which transmitted video signals as a voltage. IP camera images are sent using the transmission and security features of the IP protocol, which provides numerous benefits:

  • Two-way audio via a single network cable allows users to listen to and speak to the subject of the video (e.g. CCTV Operators at a remote location being able to use the public address system at a site to warn intruders that they are being recorded and that the police are on-route)
  • The use of a Wi-Fi or wireless network
  • Video analytics can be placed in the camera itself allowing the camera to analyze images
  • Transmission of commands for PTZ (pan/tilt/ zoom) cameras via a single network
  • Secure data transmission through sophisticated encryption and authentication methods
  • Remote accessibility  which allows live video from selected cameras to be viewed from any computer, mobile smartphones and other devices
  • PoE (Power over Ethernet) can supply power through the ethernet cable and operate without a dedicated power supply
