Network Camera Compression Techniques and Image Resolution
WH Network camera Technical FAQ
WH Network camera of the digital Image resolution is measured in pixels. The more detailed an image is, the more data, and therefore the more pixels, it contains. Detailed images require more space on a hard disk and more bandwidth for transmission.
For storing and transmitting images over the Network, the data must be compressed or it will consume too much disk space or bandwidth. If bandwidth is limited, lowering the frame rate or accepting a lower image quality will radically reduce the amount of information being sent. A number of compression standards exist that deal with the tradeoff between frame rate and image quality in different ways. Of the more common standards, both JPEG and MPEG transmit high-quality video, while the H-standards, normally used in Video conferencing, do not generate clear images of fast-moving objects.
