The two types of cables used for the installation of Security Cameras and Digital Video Recorders (DVRs) are Plug and Play Cables (PnP) and RG59 Coax Siamese cable. Each type of Camera Cable has positives and negatives about them which is disussed below.

Optical zoom leverages the physical change in a lens to adjust the distance between the camera sensor and subject, whereas digital zoom uses magnification technology to enlarge an area of an image, thereby compromising the integrity of the picture by cutting down on the megapixels.

Shutter speed is the amount of time the shutter allows light onto the CCD. The shutter speed is measured in seconds (or fractions of a second for most common pictures). The slower the shutter speed, the more motion is recorded by the camera. A tripod might be needed to use slower shutter speeds without blurring the picture. 

Most, if not all, cameras have several image quality settings to choose from. They are first broken down by resolution (e.g. 2048 x 1536, 1600 x 1200, 1024 x 768, etc) and then by quality (e.g. SHQ, HQ, SQ). What's the right one to use?The deal is this: quality is inversely proportional to the amount of JPEG compression the camera uses. Thus,

Unless it's a very expensive full-frame model, all digital SLRs will have a focal length conversion (also called a field-of-view crop factor) to deal with. Basically you have to re-train your mind to think in digital SLR, rather than 35mm terms. Let's imagine this scenario. You grab your old Canon Rebel film camera and take a picture

To be more specific: will you get better 4 x 6 inch prints from a 3 or 4 Megapixel camera versus a 2 Megapixel camera? Possibly, but the average person won't notice. The real advantage of a higher resolution camera is that with the larger image size, there's more room to crop images. In terms of quality though, it's not a huge deal. At print sizes
