1. What is Hikvision Bandwidth Calculation?

The Hikvision bandwidth calculation estimates the total network bandwidth required for a surveillance system based on the stream bitrate of individual cameras and the total number of cameras in the system.

2. How Does the Calculator Work?

The calculator uses the bandwidth formula:

Where:

• \( Stream\_Bitrate \) — Bitrate of a single camera stream in bits per second (bps)
• \( Number\_of\_Cameras \) — Total number of cameras in the system

Explanation: The total bandwidth required is simply the sum of bandwidth requirements for all individual cameras in the system.

3. Importance of Bandwidth Calculation

Details: Proper bandwidth calculation is crucial for designing surveillance systems to ensure network infrastructure can handle the video traffic without congestion or quality degradation.

4. Using the Calculator

Tips: Enter the stream bitrate for a single camera in bps and the total number of cameras. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my camera's bitrate?
A: Check your camera's specifications or settings. Typical values range from 1-8 Mbps per camera depending on resolution and compression.

Q2: Should I account for peak or average bitrate?
A: For capacity planning, use the peak bitrate to ensure your network can handle worst-case scenarios.

Q3: What about overhead for network protocols?
A: This calculator provides the raw video bandwidth. Add 10-20% overhead for TCP/IP and other network protocols.

Q4: Does this include both main and sub streams?
A: No, this calculates for a single stream per camera. If using multiple streams, calculate each separately and sum them.

Q5: How does resolution affect bandwidth?
A: Higher resolutions generally require higher bitrates. 1080p typically needs 4-8 Mbps, while 4K may need 15-30 Mbps.
