IP cameras are networked digital video cameras, which transfer data over a Fast Ethernet link. IP cameras (also known as “network cameras”) are most frequently utilized for IP surveillance, a networked and digitalized form of closed-circuit television.

Advantages of IP camera over digital technology includes:

  • Digital Zoom
  • Remote administration from any place
  • Adaptable frame rates and resolution to meet needs
  • Lower cabling needs
  • Two-way communication
  • Progressive scanning that allows good quality pictures extracted from video, majorly for moving targets.
  • Support for brilliant video

The capability to send alerts in case of suspicious activity is observed.

Flaws of IP surveillance contain greater complexity and bandwidth demands. One substitute to firm’s strong capitalization in analog technology is to utilize a video server, in effect, shift analog CCTV cameras to IP cameras. A video server is a tiny standalone server, which transforms analog signals to digital format, and offers the analog cameras with IP addresses.

Nevertheless, because it serves much more refined capabilities, IP surveillance is highly replacing analog CCTV. An industry report by International Data Corporation anticipates that shipments of IP cameras and relevant products will rise 45% between 2009 and 2013.

Web camera and IP camera differences

A web camera is attached to a PC, usually by USB, and utilizes the PC to make the video available on the network and other viewers. It won’t work correctly without a PC attached between the system, and the camera. In the other hand, IP camera is a stand-alone gadget and combines the performance of a high-end web camera, the network interface, and PC in one network-ready product.

Key strategic points

To support to make this changeover, there are three key strategic points, which shape the timing and execution of conversion tactics –

  • The largest the service being protected, the better contiguous transition to IP cameras.
  • The more advanced megapixel cameras become, the worthiest a contiguous transition to IP cameras.

This report checks these critical strategic points and reasons out with suggestions for end-users and integrators.

Some frequently asked questions about IP camera

Is it essential to get a DVR with IP camera?

No, DVR is only utilized with the older analog CCTV systems. Analog cameras are attached to the DVR by using a coax cable and BNC connector. IP cameras connect right to your network such as another computer. They have an RJ45 connection on the back, not coax.

How much bandwidth does an IP camera utilize?

The bandwidth based on the number of cameras, camera’s resolution, the used compression scheme, and the camera’s frame rate. For instance, in case a camera has a frame size of 30 Kbytes, and single frame per second has been sent, the bandwidth is 300Kbits/second.

Does the device have a separate IP address?

Yes, it performs as a standalone web-server, with little restricted memory space stored for user’s own web pages.
