Frequently Asked Questions

What is a Security DVR?
DVR stands for Digital Video Recorder. A Security DVR is capable of taking the video from digital or analog cameras and recording it into a digital format on a hard drive. It can record high quality video, maintenance free, for weeks or even months. An ideal replacement for time lapse VCRs.

What is a video capture card?
A video capture card or DVR card is a graphic card inside the Security DVR system which captures the signal from the cameras and stores the video on the hard drive.

How many hours of video can the Security DVR store?
The length of archive depends on number of cameras, frames per second (FPS) and amount of available hard disk space. Our preconfigured systems usually provide several weeks of archive on motion detect mode.

How does motion detection work? Through the camera or software?
Motion detection works through the software in the DVR system by recording video when pixels in the image change. Most Security DVRs offer a sensitivity scale so the user can set the sensitivity of the motion detection.

Can I view live and recorded video locally?
Yes.

Can I view live and recorded video remotely?
Yes, most of our Security DVR systems are Internet enabled. You can view live and recorded video from anywhere through the Internet.

What kind of broadband do I need? How much bandwidth?
Basic DSL or cable will suffice in most cases.

Can several users view one site at once?
Most Internet-enabled Security DVR systems allow multiple users to view the same site simultaneously. However, as more people look at the same cameras/DVR at the same time, the bandwidth will be shared between them.

Can I record audio?
Yes, if the Security DVR system comes with an audio option you can record audio. Most analog cameras do not come with built in audio, so you will probably need a separate audio kit.

Can I listen to live and recorded audio remotely?
Yes, some of our Security DVR systems have that option. With an optional audio module, you can listen to live and recorded audio from anywhere through the Internet.

How many cameras do I need?
This will depend on the size and layout of the area you wish to survey. On average, we recommend one camera per 1000 Sq. Ft.

Can I use my existing cameras?
Yes, you can use your existing CCTV cameras. Simply plug them into the back of the Security DVR which replaces the VCR.

What camera lens size is the best for my application?
ApexCCTV carries a large selection of security camera lenses, but the lens you will need depends on where you plan to use it. Review our Lens Selection Chart to determine the type of lens that is best suited to your needs.

What is an Auto-Iris Lens?
An auto iris lens provides consistent video signal in areas where light levels vary.

What is Lux?
Illumniation is measured in units called Lux. For more information, please refer to our LUX Explanation Page

Can I zoom in with a camera?
Yes, but you need a special camera called a Pan-Tilt-Zoom or PTZ camera. Browse our selection of PTZ cameras and find the one that is right for you.

What type of Operating System (OS) does the Security DVR use?
Most PC-based Security DVR Systems use Windows 7 Professional, and Standalone Security DVRs are Linux based.

What kind of cable should I use?
Siamese cable, which is an RG59 coaxial cable and a pair of 18 gauge wire in the same jacket to make installation easy. Check out our cables page and find the length you need.

What happens if there is power outage?
Most Security DVRs will come back on as soon as power is restored. However, we suggest an uninterruptable power supply (UPS) which provides a short period of backup power and also serves as a surge protection device.

Can I use my cash register with your POS interface?
Our GeoVision and AverMedia systems work with most PC-based and electronic cash registers. Contact us with the make and model of your register, and we can tell you if your system is compatible. View our GeoVision POS Data Catpure configuration video tutorials.

Can the Security DVR report an alarm?
Yes, some Security DVRs have that option.
