 What is a DVR?

DVR means Digital Video Recorder. This is the recording device that replaced the old video records that used tapes.

 

How do I connect my DVR to the TV?

Most of DVR’s will have at least 1 of the following video outputs, HDMI, VGA or BNC. This may allow you to view your CCTV system on a number of different types of TV or monitors. BNC Output will you to connect to your TV’s RCA input (Yellow Socket) by using a BNC/RCA Adapter. VGA Output allows you to view your CCTV system on your PC Monitor or LCD, LED TV provided it has a VGA input port. HDMI allows you to view your CCTV system on LCD,LED or Plasma TV providing it has a HDMI input. HDMI allows you to view video in high definition up to 1080p resolution.

 

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 with our system you can

 

What does 'weather resistant' mean?

Weather resistant or weather proof cameras can be used outdoors. We recommend these are shielded from direct sunlight, rain, snow and wind. Camera’s power supplies must NEVER be left exposed

 

Can I view on my Smartphone, Tablet or PC?

Most of new DVR’s and selected individual cameras have the ability to view and monitor from selected smart phone & tablet devices .

 

Can I view images remotely?

Yes, most DVR’s these days include remote viewing software. All you will need is a broadband line to which the DVR gets connected to.

 

How long will my system record for?

The short answer is as long as you want. All data is recorded to a built in hard drive, the bigger the hard drive, the longer your images will be saved. A 1TB hard drive should record four cameras (depending on frame rates) for one month. Therefore, it will record one camera for over four weeks.

 

What happens when it’s full?

Nothing. Your Digital Video Recorder will record over old images when the hard drive is full. So if you have capacity to record for 30 days, on day 31, day 1 recordings will be deleted to make room on the hard drive for day 31 recordings.

 

Do the cameras light up at night?

If your camera has infrared, yes. There will be a small row of infra red lights that cast light that’s invisible to the human eye. Without this, your camera wouldn’t be able to see in the dark.

 

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

 

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.

 

Check the Playback on your DVR

Make sure your DVR (or NVR) is recording on every channel. Don't be caught with a device that is not recording when you need it the most. Make sure the time and date are set up correctly. This will affect any scheduled recording and it's vitally important when using video in any legal matters.
