In selecting a CCTV system, it is essential to calculate the required storage capacity. By assessing the following variables, you can ensure that your CCTV system has the necessary storage capacity to record and store all the video footage.
The recording duration
If you want to store footage for a long period, you will need more storage capacity. The longer the recording, the more storage capacity you will need.
Recording Resolution
The resolution of your cameras will be a crucial factor in determining your storage needs. Higher-resolution cameras provide better video quality but also require more storage space. For example, a 1080p camera will require twice as much storage space as a 720p camera.
Number of Cameras
The storage capacity required will be dependent upon the number of cameras. The greater the amount of cameras, the larger the storage capacity will have to be.
Video compression
Video compression is another important aspect of CCTV storage. Compression allows for footage to be recorded in a smaller file size, which makes it more efficient to store and transfer.
H.265+ video compression
The most popular video compression standard is H.265+. H.265+ is an advanced standard that offers better compression than previous versions, with up to 50% more efficiency. It also offers better image quality and improved viewing performance. Overall, CCTV storage and video compression are essential components of any modern surveillance system. The use of H.265+ compression is becoming increasingly popular due to its ability to reduce storage requirements by up to 50% compared to H.264 compression while maintaining the same level of video quality. Additionally, cloud-based storage solutions are gaining popularity due to their flexibility and accessibility from anywhere with an internet connection.
Motion detection
The motion detection feature of CCTV systems is essential, as it allows users to detect activity in a designated area. There are several options for setting up motion detection, such as using sensors or programs that detect changes. In areas where no movement should take place, like secure facilities or restricted locations, motion detection is especially beneficial. Additionally, since it only captures footage when motion is detected, it can help conserve storage space.
CCTV Storage Formula
To calculate the amount of storage space needed for a camera, you can use the following formula:
Storage Capacity Required = (Camera Resolution in Pixels) x (Hours of Recording) x (Frames per Second) Length of Recording The length of time you want to store video footage will also affect your storage needs.
In conclusion, CCTV storage is an essential part of any security system. With the right storage solutions, businesses can store a large amount of footage for an extended period of time, ensuring that they have all the information they need in the event of a security breach. The use of CCTV storage also helps to reduce the risk of data loss and can provide peace of mind for business owners.
