Although the application of closed circuit security television have not changed much in recent years, tools and equipment significantly. Cameras became smaller, cheaper and better, but the breakthrough happened in recording equipment.
Therefore many customers shopping for complete CCTV monitoring and recording systems are confused by such veracity of the products available. Objective of this article is to guide buyers toward the best and most economical type of equipment, closed circuit television, based on the intended application and requirements.
Selecting the right cameras. It is almost impossible to describe all types that are available in this short article. We will focus our attention on the most popular and widely used camera types instead.
CCTV produce images using CMOS or CCD (Charge Couple Device) chips. Tiny cameras CCTV very low price usually use CMOS technology, produce poor quality images and are sensitive to poor light. Cameras CCTV decent quality CCD technology use. The size of the CCD chip is normally 1 / 4 ", 1 / 3 or 1 / 2". As a rule, the larger the size, the better the image quality produced and the higher the price. However, higher density of 1 / 4 "and 1 / 3" CCD chips can now produce as good image as many 1 / 3 "or 1 / 2" chips.
The number of TV lines in the image of the security camera is a measure of image resolution (sharpness). The greater the number of TV lines, the better the resolution and, therefore, the overall image quality. Standard resolution camera may have 350-380 lines, over 400 TV lines is generally considered good resolution while over 500 TV lines is considered high resolution. Cameras B / W chip to produce a higher resolution and higher light sensitivity, therefore suitable for use in dark areas where light conditions are poor most of the time.
The color cameras also offer a more realistic and natural. CCTV Cameras
Professional quality cameras.
Type box body has the ability to use different types and size of the lenses. Interchangeable lenses enable this camera to monitor objects from virtually any distance. Although for indoor use, it can be used for outdoor when combined with weatherproof housing. They are considered the most flexible and widely used by professionals for commercial installations.
Bullet Cameras.
Bullet cameras are, as the name suggest contained inside the bullet-shaped housing.
Most bullet cameras are weatherproof and sealed without the ability to use different lenses. The great advantage of the bullet camera is the small size and integrated design, some bullet cameras will not even have infrared LED future built. simply LED light in the infrared spectrum (not visible to human eye). This light will illuminate viewing area, making it possible to track in complete darkness. This is the great future, but only works to a certain distance (usually between 10 and 50 feet, depending on model) vary easy to install and designed estheticly, bullet cameras are the ideal choice for residential and do-it-yourself installations where track objects that are within about 25 feet from the camera location (with standard 3. 6mm lens).
Council Chambers.
Council Chambers are basically fixed lens mounted on a circuit board. These cameras can be packed in a small case (Mini Cameras) or dome (Mini Dome) or simply sold unpackaged, for mounting by the buyer. The lenses of these are either a normal industry aperture or a "pinhole" lens of very small aperture. Pinhole lens cameras are often called "spy" cameras and may be mounted in a hidden form of covert surveillance purposes. The most popular examples of discrete board smoke detector and motion detector cameras.
Because the camera lenses on board are pre-assembled, have a fixed iris and are usually of short focal length (wide, that is), the flexibility of its usefulness is limited. However, this type of camera can provide a low cost solution in the right situation, especially in a home environment. We recently described most popular types of cameras, now allows disk, how and where to use the mites.
Types of professionals with C / CS Mount target attachment generally offer best performance and many important futures, like lens control output, Back Light Compensation and many more. . .
Distance to object tracking camera is not a problem, that is why the ability to select different lenses, based on location is so important. Installation Installation is somewhat complicated and highly-recommended. We recommend this type of security cameras for commercial installations.
Most bullet cameras in comparison, does not offer high resolution and lens selection flexibility, but is likely to be weatherproof, some will have infrared light built and most of all they are relatively easy to implement. Usually come with 3. 6mm lens witch are considered adequate for most standard installations (good for covering small room or equivalent medium).
For larger rooms or longer distances, cameras with lenses of 6 mm or greater may be required. Choice that are great for any do-it-yourself installation.
Chambers of the Board however, are widely used in the hidden camera installations, sometimes called Spy Cameras. Many are basically on board with built-in transmitter. We will not go into wireless cameras right now, as this would be enough material for completely new article.
Board cameras are sold as single circuit board, for integrating into hidden camera devices. They are available in the domed housing, and vary popular Dome Camera or integrated with smoke detector, motion detector output and so on Sign. Most also come with 3. 6mm lens, although some are allowed to be replaced lens.
During the time most practical design has been Dome Camera with its aesthetic appearance blends into surroundings, especially with folding clasp, ideal for use in stores, lobbies, gas stations and other public places. Practical solution for covert installation also, motion and smoke detector cameras, are in no way replace the security alarm or fire protection. They should always be selected based on the location of the camera (inside / outside), distance of object tracking, the light condition and budget.
When shopping for security cameras, customers are faced with the fact that you have to select one or another recording device.
The days of known CCTV time-lapse recorder are almost over.
Although some customers still prefer this old fashioned recording solution, it is worth investing some extra money to buy a good quality digital video recording (DVR). Digital recorder transfers analog video stream format camera, and stores it in the hard disk. There are two main types of digital recorders on the market right now.
