Potential disadvantages of IP cameras
The following are some of the potential weaknesses of IP cameras in comparison to analog CCTV cameras.
- Higher initial cost per camera.
- Less choice of manufacturers.
- Lack of standards. Different IP cameras may encode video differently or use a different programming interface. This means a particular camera model should be deployed only with compatible IP video recording solutions.
- High network bandwidth requirements: a typical CCTV camera with resolution of 640x480 pixels and 10 frames per second (10 frame/s) in MJPEG mode requires about 3 Mbit/s.
- Technical barrier. Installation for IP Camera required a series of complicated network setting including IP address, DDNS, router setting and port forwarding. This is very difficult for most users to do alone without help from IT technician.
