CCD is used in professional cameras because of it's high resolution quality and it's ability to record in low-light situations. CCD is basically a small silicon chip that receives light and turns it into voltage variations which makes up an image. It's usually measured in inches with 1/3" CCD being the standard. They are higher priced but are great for cameras that may require vision in near darkness.

DVR cards are bundled with video surveillance software which allows the user to record and display multiple cameras simultaneously from the camera site or a remote location.
A Digital Video Recorder (DVR) system records high resolution digital images to a hard disk drive (HDD) and eliminates the requirement of maintaining VHS tapes. Since the video images are stored digitally, the image quality will not degrade overtime, as would a VHS tape when recorded over multiple times. The time-saving search capabilities of a DVR will enable the user to locate the desired video clips via user defined parameters (camera, time, date, etc.) versus the fast forward and rewind functions of a VCR. A DVR can be accessed remotely from anywhere in the world using the Internet.
The amount of time a DVR will record for is based on the size of the DVRs hard drive, the number of cameras recording and the number of frames per second it is recording at. Our stand alone DVRs uses 3.4GB per camera per day. 4 camera stand alone on 250GB hard drive will record for 18 days. 8 camera stand alone on 250GB hard drive will record for 9 days. 16 camera stand alone on 500GB hard drive will record for 9 days.

A varifocal lens is one where the focal length of the lens can be varied. This is a fancy way of saying it is a zoom lens. Most varifocal lenses have, and in almost all circumstances should have, an auto iris feature.
A fixed focal length lens cannot zoom. The focus is fixed. A fixed focal length lens usually allows more light to pass through the lens at a given focal length than a varifocal, or zoom lens. This can be important in low light situations.
