  There are many types of CCTV cameras,they can be categorized by the types of images they are able to capture,the amount of frames they can take per minute,the type of connection to the monitor or video recording device,whether they are able to move position,and special functions they can provide.

Types of Images: CCTV cameras generally take both black and white or color video images. In addition,many CCTV cameras can even have night vision capabilities which allow a CCTV camera to view and record low light images using special technology.

Frames per Second: Frames per second means the amounts of full frames that a video camera captures and sends to a recording device or monitor per second. While most CCTV camera systems are easily able to capture 30 or more frames per second (30 fps is considered real time),the amount of video tape or digital storage would be enormous to record every moment of everyday. For most stores,speeds of 1 to 6 frames per second are more than enough to catch and record a perpetrator committing a crime.

Pan Tilt Zoom (PTZ) Cameras: These types of CCTV cameras allow a person controlling the surveillance of an area to move the camera remotely,usually with an RF or wired controller. Most moveable cameras allow the person monitoring it to move the camera from right to left (pan),up and down (tilt) and from a tight angle to a wide angle (close up zoom).

Cameras with Special Accessories: Certain CCTV cameras have special functions which are made for specialty uses. For instance,there are extremely small surveillance cameras that are used for spying (Nanny Cams),there are cameras that are made for night viewing,cameras that are vandal resistant and cameras that are specifically made for indoor or outdoor uses.
  Fixed cable connection means that your camera will be physically connected to your monitor or recording device via a cable. Usually coaxial cables are used,most of the time they are similar to your normal home TV cables. Lengths come in 25,35,50,100 or 500 feet. As the distance increases,you may see degradation in signal quality. For distances longer than 100 or 200 feet,you can purchase higher quality coaxial cables such as RG59 coaxial cable for distances up to 600 feet and for distances more than 600 feet,but less than 2,000 feet,you can purchase CAT5 cable.

However each individual location will have its own operating limits. Expect most wireless CCTV cameras to send data to a range of about 200 feet,however many will more likely work well when transmitting less than 150 feet. A clear line of sight transmission will always work the best
  There are two main ways to record video images that your CCTV cameras capture; they are analog tape and digital video recorders. The vast majority of analog video recorders use VCR tapes and either standard VCR's to record the images or special security time-lapse VCR's to record images for a longer period of time.  
  A tape recorder such as a security-time lapse VCR can record CCTV camera images in either black and white or color for either 2,4,6,8,etc all the way up to 960 hours which is 40 complete days. The determining factor is how many frames per second you intend to record and how many cameras you have hooked up to your VCR for recording. For instance,if you record 30 frames per second (real time video),you will only be able to get a few hours of video captured on your recorder. If you record one frame per second or less,you can record for dozens of hours before the video tape is full. VCR's are very practical,very reliable and extremely affordable. Expect to pay only a few hundred dollars for a security VCR.  
  There are two types of DVR's (Digital Video Recorders). They are either stand alone devices or hard drives that are connected to a computer system. DVR's work similar to VCR's except the images they capture from the CCTV camera is digital. The amount of digital images you can capture on a DVR is determined by a few factors including the frames per second recorded,the amount of cameras hooked up to the DVR device,the resolution that the DVR saves the images at and the video compression used (e.g. MPEG4). For a common set up,where you have 4 cameras shooting at 30 fps and you use an image resolution of 320 X 240,each camera only records when motion is on,and you use MPEG4 compression,you should be able fill up a 20 to 25 GB hard drive in about 80 hours.  
  A DVR (digital video recorder) is a device used to record broadcast TV,cable TV or satellite TV programming. Most digital video recorders use a hard drive for storing programming data. Some people might refer to a DVR as a PVR (personal video recorder). There are four main types of DVR's; a stand alone unit,a DVR that is integrated into a set top box provided by a cable or satellite TV company,portable DVR's and DVR's that are created using components and software in a computer  
  Cable and satellite TV companies also offer many of their customers DVR's. These DVR's come with large storage capacity for recording or storing TV shows and movies at home to watch at a later time. These DVR's are usually built into set top boxes,so one box fulfills all your cable or satellite TV needs. Most cable and satellite TV companies allow their subscribers to rent these DVR's directly from them usually for a small monthly fee. There is no additional membership for TV listing services.  
  Computer DVR's are one of the newer ways many people are recording and watching their favorite TV shows. Most people watch broadcast TV,cable TV or satellite TV on their computer LCD monitor with the help of a tuner card. Computer DVR's use the internet to find TV listings,the tuner card can pipe in the video into the computer and it is easily stored on the computer's hard drive. This is quite possibly the most affordable way to have a DVR and most computer DVR users are very satisfied with the quality of it.  
  Portable DVR's are growing in popularity and are sometimes referred to as portable media devices. Not only can they transfer and store videos,but music,photos and other types of media. Some portable DVR's usually consist of just a small function screen,USB port and hard drive. Others include an LCD screen to watch video directly on the unit.

When shopping for a DVR it is important to note the important features that most DVR's come with.
  Storage Capacity is a main feature and should be a key selling point. The larger the storage capacity of your hard drive in the DVR,the more digital programming you can record. For instance,at a low resolution,you can store about 1 hour of video for every gigabyte (GB) of storage. Most DVR's usually start with about 30 GB's of storage or about 30 hours of storage capacity. Larger DVR's come with more than 200 GB. However,the larger the hard drive and storage capacity,usually the more expensive the unit.
