Once you have the video resolution and frame rate, you can calculate the bit rate. The bit rate is the amount of data that is transferred per second and is measured in kilobits per second (Kbps) or megabits per second (Mbps). To calculate the bit rate, use the following formula:
Bit rate = (Video resolution * Frame rate * Bit depth) / Compression ratio
Where:
– Video resolution is expressed in pixels.
– Frame rate is expressed in frames per second.
– Bit depth is the number of bits used to represent each pixel. It is typically 8 bits for most cameras.
– Compression ratio is the ratio at which the video is compressed. It is usually specified by the camera manufacturer and can range from 10:1 to 40:1.
4. Determine the bandwidth requirement:
Finally, to determine the bandwidth requirement, you need to convert the bit rate into a bandwidth value that your network can handle. The bandwidth requirement is measured in kilobits per second (Kbps) or megabits per second (Mbps). If you have multiple cameras, calculate the total bandwidth requirement by summing up the individual camera bandwidth values.
Example:
Let’s say you have a wireless security camera with a video resolution of 1080p (1920×1080 pixels), a frame rate of 25 fps, a bit depth of 8 bits, and a compression ratio of 20:1.
Using the formula mentioned above, the bit rate calculation would be:
(1920 * 1080 * 25 * 8) / 20 = 207,360,000 bits per second or 207.36 Mbps.
So, the bandwidth requirement for this camera would be 207.36 Mbps.
