Understanding the Bandwidth specifications of cameras for AI video surveillance
Computer Networking runs on bandwidth and it has become one of the relevant elements of video surveillance systems too. Video surveillance consumes an immense amount of bandwidth, and its specifications need to be precise and lucid. Different variations in the bandwidth load of surveillance cameras are valuable and have a clear understanding of bandwidth. Availability of Bandwidth is one of the relevant concerns for any network and video transmission can carry a relevant load which many struggle to gauge the specifications and nuances impacting the security cameras and bandwidth.
In this in-depth guide, we are going to delve deeper into the major aspects of bandwidth. To maximize resource efficiency and operate properly every system will be required to address certain related factors comprising a complete understanding of cloud and hybrid cloud systems. It helps in prioritizing low-bandwidth devices and weighing scalability considerations.
What is the bandwidth usage for 2MP and 4 MP cameras?
At the time of setting up a camera system, bandwidth utilization is relevant to understanding keeping a smooth flow of video streaming without exceeding your network's capacity. In this context, the blog explains the various bandwidth requirements for distinct configurations of 2MP i.e. 19201080 and 4MP i.e. 25601440 cameras effectively concentrate on the way bitrate impacts bandwidth usage.
What is bandwidth & what are its requirements?
Bandwidth is defined as the amount of data that can be seamlessly transmitted over the network per second (generally measured in megabits per second or Mbps). A number of factors impact the overall usage of bandwidth within a camera system as so as in AI video surveillance.
Frame rate
With higher frame rates capturing videos, more pictures can be taken per second affecting the bandwidth slightly.
Resolution
Higher resolution means more detail, which generally requires more data to transmit.
Bitrate
This is the most significant factor. Bitrate determines how much data is sent each second, directly impacting bandwidth usage. In different situations bandwidth increases with Max bitrate and there is a significant reason behind it. When two cameras share the same resolution and frame rate, an increased bitrate results in more data being transmitted seamlessly.
Video compression and bitrate
Advanced coding methods that are coming up nowadays assist in reducing overall file size however bitrate plays a relevant role. It helps in preserving more detail in video data and prevents any loss of quality in the video stream.
Bitrate controls video quality
When the bitrate percentage is higher, it allocates more data to each second of video which, in turn, improves quality during complex scenes with more details. For instance, two cameras with a configuration of 1920*1080 resolution and 25 fps are more likely to appear similar. However, the one with the 2 Mbps bitrate promotes more compression and delivers lower-quality video. Contrarily, the one with 8 Mbps bitrate will transmit more data to preserve quality.
Bandwidth Usage for Different Camera Configurations
A. 2 MP Camera (1920x1080) Configurations
If we calculate the daily bandwidth for each 2 MP configuration with varying max bitrates, this can be the result.
2 MP Camera, 25 fps, H.265 Encoding
In short, higher bitrates enable more data transmission leading to improved video quality however, at the cost of higher bandwidth usage. 2 Mbps is excellent for standard-quality video and 8 Mbps is effective for premium-quality video with more detail and motion.
B. 4 MP Camera (2560x1440) Configurations
Let’s take a look at the bandwidth usage for 4 MP configurations with different max bitrates.
4 MP Camera, 25 fps, H.265 Encoding
A 4 MP camera requires more data than a 2 MP camera as a result of higher resolution even at the same bitrate. While 4 Mbps administers standard quality and delivers superior quality but uses more bandwidth.
Advanced features to reduce security system bandwidth system
Multiplexing
Multiplexing is a bandwidth utilization technique that enables unlimited users to observe the same live stream without impacting the camera’s uplink consumption. When accessed remotely, video is proxied through cloud service providers. It can be cached to reduce the impact on the local area network and speed retrieval.
Steadfast state
In a steady state, an individual camera comes with a bandwidth footprint of 20 Kbps per camera. Therefore, any organization can have over 100 cameras on the same connection harnessing 2 Mbps.
Motion detection
AI video surveillance system comprises one of the significant features of video motion detection. Strategically, it reduces bandwidth and storage usage. Additionally, motion detection helps in triggering recording in a higher resolution.
Key Takeaways
It is important to keep in mind that data bandwidth and video stream quality are related to each other.
