CALCULATING TOTAL FPS

Add the Frames Per Second for all the Cameras together. For Example: 16 Cameras set to record at 5 FPS each would be a TOTAL of 80 FPS.

NOTES
* 720x480 Resolution cannot exceed 60 FPS

How to Use This Calculator

Enter in the frames per second rate (note not to exceed 120 FPS for 4 camera DVR and not to exceed 240 FPS for all other DVRs). Enter in the percentage of motion detection activity you will monitor. Days of recording will automatically change for each size of hard drive based on your entries.

Understand Digital Video Storage
All DVRs record video images to a hard drive. The hard drive is a data container that has a limit to how much video information it can hold. The bigger the hard drive the longer it can record video before becoming full and recording over the oldest information. There are ways to get more days of video recording out of a hard drive. This includes lowering the frame rate, recording only when there is motion and scheduling recording.

It is important to note that none of these three methods of squeezing more video days out of your hard drive affects the live streaming and smooth live motion quality of watching a monitor hooked directly into the DVR. The following techniques only affect recorded information.

Frame Rate. POM Technologies DVRs come with 120 frames per second (FPS) for its 4 camera DVR and 240 frames per second for all other DVRs it sells. Think of frames as being still picture snapshots. The more snapshots per second the smoother the video motion. Also the more snapshots the more information needs to be saved on your hard drive. The number of FPS for each camera attached to your DVR can be individually adjusted. Reducing the number of frames per second increases the length of time the DVR can record. You can also adjust individual security cameras so the most important areas have more frames per second than other areas.

Motion Detection. Typically you only want to see video if something is happening. What are important are people working, customer interactions, movement of vehicles and equipment, etc. Everything else is typically dead air”. POM Technologies DVRs all come with motion detection software built into the unit. By activating the software, which can be adjusted to watch particular areas or adjusted for various levels of motion sensitivity, you can greatly reduce the amount of “dead air” recorded and increasing the number of days the DVR records information.

Scheduling. Just like programming a VCR, all POM Technologies DVRs can be scheduled to record at specific ranges of time. This way you record only when people are supposed to be present. Scheduling can greatly increase the number of days the DVR records information and combining it with motion detection insures after hours activities get recorded.
