Does a CCTV system work without a hard disk?
When installing the hard drive for DVR / NVR
Some clients can use a normal desktop hard drive for their DVR / NVR monitoring needs.
But this is totally wrong.
The traditional desktop hard drives are made to work only for 8 hours a day and 6 days a week.
Therefore, the total workload will be a maximum of 10% -20%.
And its performance will be low to moderate.
Therefore, they usually show a low mean time between failures.
While a surveillance hard drive is an essential component for digital video surveillance storage.
It can be used in a Video Management System DVR, NVR, video server or in order to work 24 hours a day and 7 days a week.
These hard drives need to be always active, in order to keep the live video tests.
In general, the use of a surveillance hard disk will be moderate to high and any type of interruption in the hard disk will affect several users.
Therefore, manufacturers of hard drives offer this type of units often offered with high mean time capacity between failures.
Some Seagate hard drive manufacturers will also offer a firmware.
Such as a rescue service plan to recover data from the hard drive caused by hard failure due to mechanical failure or accidental damage.
For Hard Disk Surveillance Units, you can choose Seagate or Western Digital brand.
Before choosing a hard drive, it is also necessary to consider the following aspects that will determine the storage capacity of your recorder:
- The number of cameras you are using will affect the appropriate DVR or NVR hard disk size.
- The resolution of these cameras (low, medium or megapixels), the higher the resolution of the camera, the better the quality of the video, and this will increase the storage requirements.
- The frames per second rate that you select for each camera (7.5, 15, 20 or 30 fps), for the highest rate of images you need the largest storage capacity.
- The length of time you want the DVR to record (one, two, three weeks or more). Once you have evaluated the number of cameras, the resolution and frame rate, determined how much time can be recorded before the oldest of the days is deleted, you will be able to decide which size of the hard drive is best for your needs video surveillance.
