As technology continues to evolve, video surveillance has become an essential part of our lives. From personal security to business surveillance, we rely on video surveillance to keep us safe and secure. However, one question that arises when setting up a video surveillance system is how much storage is needed to store footage.
The amount of storage required for video surveillance depends on various factors, such as number of cameras, resolution of cameras, frame rate, and length of time footage needs to be stored. In general, higher resolution and frame rate, more storage is needed.
Let's take an example of a 1080p camera that records at 30 frames per second. Such a camera can consume up to 10GB of storage per day if it records continuously. This means that a 30-day recording of such a camera would require approximately 300GB of storage. If we add more cameras to system, storage requirements increase accordingly.
If video surveillance system is set up for business purposes, it is essential to consider retention period. Some companies might have a retention period of 30 days, while others might need to store video footage for up to one year. The longer retention period, more storage is required. As a general rule of thumb, it is recommended to have at least one month of storage capacity.
Another factor to consider is type of storage device used. Most systems use hard drives to store video footage, but there are also options such as network-attached storage (NAS) devices and cloud-based storage. The type of storage device used can affect overall cost of system, so it is important to consider both cost and benefits of each option.
In addition to above factors, it is also essential to consider compression format used in video surveillance system. Compression helps to reduce size of video file without reducing quality. Some popular compression formats used in video surveillance systems are H.264 and H.265. Choosing right compression format can help save storage space while maintaining quality of video footage.
In conclusion, amount of storage required for video surveillance depends on various factors such as number of cameras, resolution, frame rate, retention period, and compression format used. It is essential to carefully consider each of these factors when setting up a video surveillance system to ensure that system is efficient, cost-effective, and meets specific needs of user.
