Explaining H.264 can be a bit technical. To put it in a simple way, H.264 is an industry standard for video compression, the process of converting digital video into a format that takes up less capacity when it is stored or transmitted.
Video compression or video coding is an essential technology for applications such as CCTV Camera, digital television, DVD and Blu-Ray disks, mobile TV, videoconferencing and internet video streaming. Standardising video compression makes it possible for products from different manufacturers such as encoders, decoders and storage media to inter-operate. An encoder converts video into a compressed format and a decoder converts compressed video back into an uncompressed format.
H.264 is perhaps best known as being one of the codec standards for Blu-ray Discs; all Blu-ray Disc players must be able to decode H.264. It is also widely used by streaming internet sources, such as videos from Vimeo, YouTube, and the iTunes Store, web software such as the Adobe Flash Player and Microsoft Silverlight, and also various HDTV broadcasts over terrestrial (ATSC, SBTVD, DVB-T or DVB-T2), cable (DVB-C) and satellite (DVB-S and DVB-S2).
In conclusion, rest assure that all of our CCTV cameras use H.264 compression technology. You will have the best quality of video footage during the internet transmission.
