New coding technology
The amount of data for monitoring video is very large. If it is raw data, a 2 megapixel camera can store the entire hard disk in just one day!
Therefore, compression coding is very important!
In the past, H.264 technology can compress 2 million cameras a day's raw data to about 40G.
However, the development trend of surveillance is high definition, and the camera pixels are getting higher and higher, from 1 million to 2 million to 3 million, 4 million or even 5 million.
H.264 technology has been unable to adapt to higher and higher pixels, so H.265 technology is coming!
2, H.265 compression capacityDoubled H.264
Compared with H.264, H.265 technology doubles the compression capacity. For example, the previous 2 million cameras have a storage capacity of 40G per day. Then, the 2 million cameras with H.265 technology have a storage capacity of only 20G per day!
3. What can H.265 bring?cost! cost!
H.265 technology can reduce us a lot of costs.
3.1, hard disk cost
Example:
Four 3 million cameras are stored for one month.
With the previous H.264 technology, four 3 million deposits are required for one month: 60G × 4 × 30 = 7.2T
That is, you need 2 4T hard drives.
What about the technology of H.265?
Only need: 30G × 4 × 30 = 3.6T
Only one 4T hard drive is needed!
With H.265, small projects can save a thousand dollars of monitoring hard drive!
3.2, bandwidth cost
The remote demand for monitoring is now very large. Many customers will require remote mobile phones and computer monitoring, which requires relatively high network bandwidth.
In the past, H.264 technology, if you need to remotely watch a 3 megapixel HD image, you need 6M of upstream network bandwidth, which means that 4M network remote can't see 3 million HD effect.
The new H.265 technology, 4M bandwidth can see a 3 million HD screen, 2 2 million HD screen, 10M bandwidth, can see 3 3 million HD screens together, 5 2 million HD screens!
With H.265, you no longer have to buy higher network bandwidth for monitoring!
3.3, equipment cost
As mentioned in 1, the four 3 million cameras are stored for one month, and only one hard disk is needed, which means that it is enough to buy a more affordable one-position video recorder!
Moreover, when there are a lot of surveillance cameras, 25 2 million cameras only need to use a 100-megabit switch, and you don't need a dozen cameras to switch to a Gigabit switch.
With H.265, let your VCRs and switches do not need to change "high match"!
H.265 technology is necessary to replace H.264 technology, Hikvision channel is the first to introduce H.265 products, leading the new era of coding technology!
