|Security is critically important and with celuoid and Video cassette tapes becoming extinct, it was only natural that CCTV and Surveillance recording with become completely digital. More and more cameras are popping up in cities across the globe and all those hours and hours of footage needs to live somewhere.|
More so, it has to be stored somewhere that is readily accessible at the touch of a button, or else what good is days worth or recording without the means to efficiently access it in real-time. Hard Drive manufacturers realised this fact a long time again and have been producing Hard Drives specially designed for Heavy Writing (the act of recording data to a disk) and Heavy Reading (the act of accessing and retrieving data from a Disk) symultaneously or more one than the other!
1. The number of cameras you are using will affect the appropriate DVR or NVR hard drive size.
2. The resolution of these cameras (low, medium or megapixel), the higher the camera resolution, the better the video quality, and this will increase the storage requirements.
3. The Frames per Second rate you select for each camera (7.5, 15, 20 or 30 fps), for the higher the frame rate the more storage is needed.
4. The length of time you wish for the DVR to record (one, two, three weeks or more). Once you have assessed the number of cameras, the resolution and frame rate, determined how much time you can record before the oldest day is deleted, you will be able to decide which size hard drive is best for your video surveillance needs.
Customize each camera’s frame rate down to a rate the your are comfortable with. Reducing the FPS (Frames per Second) to 7.5 to 15 FPS from 30 FPS will substantially increase the recording time, without reducing your quality.
There are several exceptions to this, for example, if you are monitoring cashiers or capturing license plates on moving cars, we recommend that you record at the highest frame rate possible, which is 30 FPS for most DVRs.
