What is a DVR?

DVR Stands for Digital Video Recorder. It is a computer that does video recording. A DVR tries to give you the best of both worlds, it gives you digital recording of the camera while preserving it as a digital image that can be copied without loss of detail.
DVRs also give many enhanced features such as user defined motion detection areas, scheduled recording, triggered recording, automatic overwriting of old data when the drive is full, password control, all with a graphical interface screen.
Just as the computer industry is changing, so is the DVR. New methods and capabilities are showing up all the time! - Updated: September 11, 2003.

  What about the video doorbells? 

An interesting innovation has occurred in the video answering field. There are a variety of systems now on the market that let you use the existing doorbell wiring to add a video camera and two-way voice. You can stay safe and comfortable and see and talk to someone at your door.

What about the new wireless systems? 

Miniaturization has done much to change the world we live in. The wireless systems are much simpler to install and get going. They do, however, have limitations which you should consider.
1. Being battery powered you have to be very vigilant about changing the batteries.
2. They operate over the air and are subject to "radio" interference.
3. The setup procedures can be difficult in all but the most basic installations.
4. If you install it yourself you don't have the years of wisdom that a professional security expert brings to the design and implementation of the system. - Updated: January 11, 2002

    How much will a CCTV system cost?

The short answer is $100.00 and up. It all depends on what you want to monitor (people, locations, machinery, ets.). Where you want to monitor (inside, outside, ec.), and what you want to do with the results (view, record, publish on the internet, etc.).
Since there are so many variables involved that it is truly impossible to have a one-system-fits-all price. - Updated: January 11, 2002

    Can I record my babysitter?

Most states and localities allow video monitoring and taping of locations inside your house. Local "Common Decency" laws can influence what you can and can't do so you need to research your options or call a security professional familiar with your local rules. - Updated: January 11, 202
