More hard drive space means more video can be stored in an archive. For example a 60GB compared to 600GB could mean the difference between having 4 days or 40 days worth of video.

As a general rule, bigger is better. An image at 640 x 480 will give a much larger and clearer picture as opposed to 320 x 240.

FPS represents how many still frames the camera records per second. Television and film is normally recorded at 24 to 30 frames per second to fool the eye into thinking it's seeing continuous motion. The more frames per second recorded, the more fluid the video will appear to the viewer. Typically, digital surveillance systems list the total FPS available for the entire system. A 16FPS system with 16 cameras records at 1 FPS per camera, while an 80FPS system with 16 cameras records at 5 FPS per camera. The i3DVR Systems start with 120 FPS with options up to 480 FPS. Also, variable speed settings are available so the user can set the FPS for each individual camera to the speed they desire. For example, a camera viewing the dumpster or parking lot may not be as important as the one viewing the point of sale, therefore the speed can be lowered. Below is an example of a six-second segment recorded at three different speeds. Notice how much information is missed at lower speeds.

1 FPS	5 FPS	10 FPS

Make sure you choose a system that will give you the quality you need.

The ability to record audio in addition to video. The DVR can record audio from one location, usually the POS area, so the user can see AND hear what's happening.

Remote monitoring is the ability to view data on your video surveillance system from a remote location, such as your home or another office. Software and a high speed (broadband) internet connection is all you need. Remote monitoring can be done using a dial up internet connection but the connections are usually too slow to receive a quality transmission of video. Remote monitoring can also work using a local area network.

Video Systems that record to VHS tape record everything even when nothing is happening. Digital video surveillance systems can use VMD to detect movement, enabling the system to record only when there is activity (a person walking, or any form of movement). VMD cuts review time because you won't see video of a stationary screen.

The DVR has the capability to adjust the sensitivity of the motion detector so the user can fine-tune the speed or rate of movement the system will detect.

Save short segments of any video you like by recording it to a CD/DVD. If there is an accident, theft, or other activity that you would like to save, simply copy it to a storage disk. Disks can be formatted to be used on any computer with a CD-ROM/DVD-ROM drive. This allows for easy distribution of recordings to managers, owners, or law enforcement. Video saved on a DVR unit is also watermarked to prevent tampering, which also makes the video admissible in court.

The DVR software is Windows-based in a PC environment. Users familiar with Windows will have an easy transition when learning our video surveillance systems. Future upgrades don't require you to purchase an entire new system, only a simple software update. A stand-alone video system will go obsolete faster because it can't be upgraded or changed as easily.
