What is IP camera ?


Network IP Cameras have been around for at over a decade now. Only recently have cabling installers began to pay attention to the technology because surveillance cameras have traditionally run on separate coaxial cable. Around 10 years ago, the first digital IP camera connected directly to a data network which changed the future of the surveillance camera industry.

During the early stages, the technology was not as professional as analog cameras. Most cameras were seen as ‘web cameras’, which were used to view objects or events over the internet or a LAN.

Today IP network cameras meet the same requirements and specifications as analog counterparts and in many areas surpass analog camera performance and features . Forecasts show that the network IP camera market share is growing at a much faster rate than its analog competitor and has surpassed the analog camera in market share.

An IP Camera is a networked digital video camera that transmits data over a Fast Ethernet link. IP Cameras (also called “network cameras”) are most often used for IP surveillance, a digitized and networked version of closed-circuit television (CCTV).
Benefits of IP camera over analog technology include:
  • Remote administration from any location.
  • Digital zoom.
  • The ability to easily send images and video anywhere with an Internet connection.
  • Progressive scanning, which enables better quality images extracted from the video, especially for moving targets.
  • Adjustable frame rates and resolution to meet specific needs.
  • Two-way communication.
  • The ability to send alerts if suspicious activity is detected.
  • Lower cabling requirements.
  • Support for intelligent video.
Disadvantages of IP surveillance include greater complexity and bandwidth demands. One alternative for organizations with substantial investment in analog technology is to use a video server to, in effect, turn analog CCTV cameras to IP cameras. A video server is a small standalone server that converts analog signals to a digital format and provides the analog cameras with IP addresses.
Nevertheless, because it offers much more sophisticated capabilities, IP surveillance is increasingly replacing analog CCTV. An industry report from International Data Corporation (IDC) predicts that shipments of IP cameras and related products will increase 75% between 2012 and 2015.
