CALCULATING HOW MUCH STORAGE YOU NEED FOR YOUR DVR
When designing your surveillance system not only do you need to determine the type and style of cameras or resolution will work best, you also need to figure out which recorder (DVR / NVR) will be both compatible and will hold the amount of video desired. Optiview is proud to offer a huge variety of storage solutions for all of your surveillance recording needs. Our recorders range from a single 6 Terabyte (TB) hard drive to up to 128 Terabytes (TB) of storage over 16 hard drives. Choosing your solution will be based on several generic variables.
The general rule of thumb is that you’ll want to calculate based on [X] gigabytes used per camera, per day, multiplied by the number of days you’re looking to have recorded at all times. These calculations are also based on having the standard H.264 compression (for both camera and recorder) and setting your recorder to record at VBR (variable bit rate) opposed to CBR (continual bit rate) at full time. If you set up for 50% motion these numbers can be reduced by up to half.
