At present, there are several resolution specifications mainly used in the surveillance camera industry, including QCIF (176×144), CIF (352×288), HALF D1 (704×288), D1 (704×576), etc. Among them, CIF resolution is the most common and is adopted by most surveillance products. The market acceptance of CIF resolution is due to the following main reasons:
Today's digital surveillance cameras need to ensure that the demands on the video stream are not too high.
There are also limitations on the bandwidth of video transmission.
HALF D1 and D1 resolutions can improve image quality and meet the high quality requirements that come with high video streams.
Adopting CIF resolution usually results in a signal-to-noise ratio of 32db or higher, which can meet the requirements of general users, but is not the ideal choice for video quality.
Now industry experts are exploring HALF D1 resolution to strike a balance between CIF and D1. WEILAILIFEI continues its quest to provide higher performance surveillance solutions both outdoors and indoors to meet the different needs of customers.
