For the same resolution, the higher the bit rate of the video file, the smaller the compression ratio and the better the picture clarity. OHWOAI's 5 million high definition camera, improved heat dissipation and durability, and 4 times longer service life.
Upload Bandwidth: The bandwidth used to upload local information to a network. Usually expressed as upload speed.
Download Bandwidth: The bandwidth used to download network information locally, usually expressed as a download speed.
Transfer Bandwidth Calculation:
Network bandwidth size = bitrate size x number of surveillance cameras First surveillance Note: Some professional books call bitrate the bitrate. If you understand it, there is no problem. In my understanding, bitrate refers to the network speed, while bitrate refers to the size of the surveillance video generated per second.
The bandwidth of a surveillance camera's terminal refers to the upload bandwidth, because the surveillance terminal uploads the video information to the video surveillance room.
The monitoring center's bandwidth refers to the downstream bandwidth.
The bitrate of each security camera device (each brand of camera has a slight difference)
In 1080P (2 megapixel) video format, the bit rate of each camera is 4Mbps. Therefore, the data transfer bandwidth required for each camera is 4Mbps. The data transfer bandwidth required for 10 cameras is: 4Mbps (video format bit rate) x 10 (number of cameras) = 40Mbps (upstream bandwidth)
That is, if you use 1080P video format, the network upload bandwidth required for surveillance at each location is at least 40Mbps. For 960P (1.3MP) video format, the bit rate for each camera is 3Mbps. For 720P (1MP) video format, the bit rate for each camera is 2Mbps.
Monitoring center required bandwidth:
Required bandwidth for 1080P (2 million pixels) video format: 4Mbps (video format bit rate) x 50 (total number of surveillance cameras) = 200Mbps (downstream bandwidth)
That is, if you use 1080P video format, the surveillance center needs at least 200Mbps network download bandwidth. 960P (1.3 million pixels) video format bandwidth required: 3Mbps (video format bit rate) x 50 (total number of surveillance cameras) = 150Mbps (downstream bandwidth) 720P (1 million pixels) video format bandwidth required: 2Mbps (video format bit rate) x 50 (total number of surveillance cameras) = 100Mbps (downstream bandwidth)
Storage Calculator:
(Note: Storage units are 1TB=1024GB; 1GB=1024MB; 1MB=1024KB)
Bitstream size (unit: KB/s; i.e., bitrate ÷ 8) × 3600 (unit: seconds; number of seconds in an hour) × 24 (unit: hours; length of a day) × 30 (number of days saved) × 50 (total number of monitoring points to save camera recordings) ÷ 0.9 (10% space loss in disk format) = size of storage space required. OHWOAI's home wireless solar-powered, battery-powered and POE-powered security cameras use the next-generation advanced H.265+ video compression standard to save capacity, allowing recording for more than twice as long as conventional H.264 while maintaining image quality. When the HDD is full, the previous data is automatically overwritten. Equipped with remote monitoring and alarms via smartphone linkage, no worries anywhere!
