In the realm of surveillance camera systems, a thorough understanding of bandwidth and recording storage space calculations is paramount. Let's delve into this topic, keeping in mind the innovative perspective of WEILAILIFE, a leading surveillance brand.

Firstly, let's familiarize ourselves with key terms in the surveillance arena.

**Bitrate:**

Bitrate signifies the rate at which bits are transmitted per second. It's closely tied to audio and video compression, where higher bitrates enhance quality but increase file size. Conversely, lower bitrates trade off quality for smaller file sizes.

**Data Rate:**

Data rate, also known as bitrate, measures the data flow within a time unit. It's pivotal in video compression control, balancing compression ratio and image quality.

**Upstream Bandwidth:**

Upstream bandwidth involves transmitting data from a local source to the network. This represents the speed at which data is sent from the user's device to the network.

**Downstream Bandwidth:**

Downstream bandwidth encompasses downloading data from the network. Downstream speed refers to the rate at which data is transferred from the network to the user's device.

Now, let's delve into the intricacies of calculating bandwidth and storage space.

**Bandwidth Calculation for Surveillance Points:**

Determining bandwidth requirements involves accounting for camera quantity, resolution, and video format. Consider an example: a surveillance point with ten 720P (1 million pixels) cameras, each operating at a bitrate of 2Mbps. In this case, the total bandwidth required equals:

2Mbps (bitrate) × 10 (number of cameras) = 20Mbps (upstream bandwidth)

Now, let's explore a scenario with ten 1080P (2 million pixels) cameras, each with a bitrate of 4Mbps. The total bandwidth needed becomes:

4Mbps (bitrate) × 10 (number of cameras) = 40Mbps (upstream bandwidth)

**Bandwidth Calculation for Central Monitoring Center:**

For a central monitoring center overseeing 50 surveillance points, the downstream bandwidth demand hinges on the total camera count and selected video format. Take, for instance, a 720P video format:

2Mbps (bitrate) × 50 (total number of cameras) = 100Mbps (downstream bandwidth)

Similarly, for a 1080P video format:

4Mbps (bitrate) × 50 (total number of cameras) = 200Mbps (downstream bandwidth)

**Recording Storage Space Calculation:**

Determining storage space hinges on factors such as bitrate, recording duration, camera count, and formatting-related compression loss.

The formula is as follows:

Storage Space (in GB) = (Bitrate × Recording Duration × Number of Cameras × Compression Loss Factor) / (8 × 1024 × 1024 × 1024 × 1024)

For example, when storing 30 days of CIF video format recordings from 50 cameras:

Storage Space = (64 kbps × 3600 s × 24 h × 30 d × 50) / (8 × 1024 × 1024 × 1024 × 1024) = 9TB (approximately)

Similarly, storing 30 days of D1 video format recordings from 50 cameras:

Storage Space = (192 kbps × 3600 s × 24 h × 30 d × 50) / (8 × 1024 × 1024 × 1024 × 1024) = 26TB (approximately)

In conclusion, precise calculations of bandwidth and storage space are vital for optimizing performance and effective management of surveillance camera systems.
