CCTV Surveillance Software

A Focus on Disk Space and Intelligent Detection

Why Continuous Recording?

Continuous recording is essential in public places like airports, train stations, crowded streets, highways, and large shopping centers. Continuous footage is crucial for post-event analysis, criminal investigations, and general security monitoring.

How Much Disk Space Do You Need?

Let's start with a calculation to understand the disk space requirements for continuous recording. We'll consider two popular resolutions: 1080p and 4K.

A 1080p video with 30 frames per second (FPS) typically takes up about 2.5 MB per second.

A 4K video with 30 FPS generally requires around 10 MB per second.

Disk Space Calculation for 1 Year For 1 year (365 days) of continuous recording, the calculations would be:

Disk Space (GB)=Frame Rate (FPS)×MB per second×60 seconds×60 minutes×24 hours×365 days÷1024

Let's do the math for various frame rates. Here is the table showing the disk space requirements for different frame rates for both 1080p and 4K resolutions:

The calculations in the table were made for 1 year of continuous recording. If you have multiple cameras, you would need to multiply the values in the table by the number of cameras to estimate the total storage requirement for all of them for a one-year period.
As you can see, the storage requirements can get massive, especially for 4K videos at higher frame rates.

Timelapse recording is a powerful tool for optimizing disk space in CCTV surveillance systems. By capturing fewer frames per second, timelapse allows you to maintain continuous video recording while significantly reducing storage requirements. This makes it a viable option for environments where constant motion is not a concern.

However, it's crucial to understand the limitations of timelapse recording, especially in scenarios where high-speed motion is involved, such as monitoring fast-moving vehicles. In such cases, capturing only one or a few frames per second may mean that you miss critical events, as the object in question might not even appear in the frame within that brief time.

Therefore, while timelapse offers a cost-effective solution for reducing storage needs, it is essential to weigh its benefits against its limitations to make an informed decision on its appropriateness for your specific surveillance requirements.


Intelligent Detection: A Way Forward

Object and Motion Detection with Web Camera Pro

Web Camera Pro and VideoSurveillance.Cloud are effective tools for enhancing the security of your home or business. They offer real-time monitoring and allow you to quickly respond to emergencies, even in challenging lighting conditions. One of the primary advantages of this software is that it allows you to quickly respond to emergencies, such as fires, floods, or other issues that may arise inside or outside the property. By providing real-time footage of the situation, Web Camera Pro software can help you understand the situation accurately and take the appropriate actions to mitigate the problem.

Traditional systems rely on pixel change detection, leading to false alarms due to changing light conditions or minor changes in the scene. However, Web Camera Pro uses advanced object and motion detection algorithms to reduce false alarms. Recording begins only when a specific object—like a human or an animal—enters the frame. This not only saves disk space but also makes the surveillance more targeted and effective.

Cloud Storage with VideoSurveillance.Cloud

Another solution to the disk space problem is cloud storage. VideoSurveillance.Cloud allows you to store critical events on a secure cloud server. This provides you with an additional layer of security, as the data is safe from hardware failure and unauthorized access.

By integrating these advanced features, we can transition from merely recording events to actively responding to them, thereby creating a more secure and efficient surveillance system.
