Welcome To ESLI's DVR Storage Calculator

 

One of the most overlooked upgrades when purchasing a digital video recorder (DVR) is the size of the hard drive.

 

Fortunately, our DVR Storage Calculator will help you determine what HD size is right for your specific situation.

 

Try several scenarios that best fit your particular situation.

 

Bytes are measured through the power of two's!

  • One gigabyte is two to the 30th power in bytes, equaling 1,073,741,824 bytes, or 1,048,576 kilobytes or 1,024 megabytes.

  • One half of 1,024 megabytes is 512, therefore, 512 megabytes is equal to one half of a gigabyte and half of a terabyte is 512 gigabytes.

 

                             Let's Get Started!


 

 

 

 

 

 

 

 

1. Minimum number of days needed to store video:  

2. Total number of cameras connected to your DVR:  

3. Frames per second on one camera*:  

4. Total number of hours each workday DVR is recording**:  

5. Total number of days DVR will be active in a typical workweek**:  

Suggested Hard Drive Storage***...   

FPS = Frames Per Second   -  DVR = Digital Video Recorder  -  HD = Hard Drive

 

*If  the total FPS recording speed is 160 on your DVR and, you have 16 cameras connected to your system, you divide 160 ÷ 16. Therefore Ten is the response to the question "Frames per second on one camera"

 

**If your DVR is set to record on motion, do not include days and/or hours when the recording area is clear of traffic.

 

***Other factors may influence the DVR's hard drives storage capacity as well as the number of days your DVR will store video. Most common are HD compression and resolution. As with all advice listed on eyespyli.com or other publications, we try to give you a starting point. All CCTV jobs are different and individual needs have to be taken into consideration. Please check with one of our trained representatives with your specific requirements before starting any job.
