Why does H.264 always appear in IP camera?
If you are looking for an IP camera for your home or business security, the tag "H.264" must have attracted your attention. But what is it?
What is H.264?
H.264 is a new generation video compression format, also known as MPEG-4AVC. Developed for high definition systems use like HDTV, Blu-ray and HD DVD as well as low resolution portable devices - such as Sony's PSP and Apple's iPod, H.264 offers better quality at lower file sizes than both MPEG-2 and MPEG-4 ASP.
The advantages of an H.264 IP camera
1. Low bit rate
Compared with MPEG2 and MPEGASP compression technology, the amount of data compression is only 1/8 of MPEG4, 1/3 MPEG2 with the same image quality. As a consequence, the use of H.264 compression technology will greatly save the user's download time and data traffic charges.
2. High quality images
H.264 can provide continuous, smooth high quality image (DVD quality). It is essential in security surveillance.
3. Strong fault tolerant property
H.264 provides the necessary tools to solve the common issues occurring in an unstable network environment, such as data packet loss, and so on.
4. High compatibility with network
H.264 provides the adaptation layer network, allowing the H.264 file to be easily transmitted on different networks (such as Internet, CDMA, GPRS, WCDMA, CDMA2000, etc.)
To be honest, nowadays, the H.264 is used by almost all IP cameras, so the slogan "H.264" is not the main reason to purchase an IP camera. You should consider other factors, such as "PTZ", "motion detection", and more.
