Although the application of CCTV security have not very much in recent years greatly changed, the tools and equipment significantly. Cameras became smaller, cheaper and better, but the big breakthrough happened in recording equipment.
Therefore, many customers shopping for a complete video surveillance and recording systems are characterized by such a truth of available products to be confused. The aim of this Article is to guide buyers to the best possible and most economical type of CCTV equipment, based on intended implementation and requirements.
Choosing the right cameras.It is virtually impossible to describe all kinds of those available in this short article. We focus our attention on the most popular and most frequently used camera types instead.
CCTV produce images using CMOS or CCD (Charge Couple Device) chips. Tiny, very low price CCTV cameras usually use CMOS technology, to poor image quality and have a very poor light sensitivity. Decent quality CCTV cameras use CCD technology. The size of the CCD chip is normally 1 / 4 ", 1 / 3" or 1 / 2 ". As a rule of thumb, the larger the size, the higher the quality of the image produced and the higher the Price. But higher density 1 / 4 "and 1 / 3" CCD chips can now as good an image as many 1 / 3 "or 1 / 2" chips.
The number of TV lines in the security camera image is a measure of image resolution (sharpness). The greater the number of TV lines, the better the resolution and image quality. Standard resolution camera may be 350-380 lines, over 400 TV lines is generally considered good resolution while over 500 TV lines is as high resolution. B / W chip cameras produce a higher resolution and better light sensitivity, therefore suitable for use in dark areas where the light is bad most of the time.
On On the other hand color cameras offer a realistic and natural images. CCTV cameras
Professional cameras.
Have box type body with the ability to using different types and sizes of the lenses. Exchangeable lenses enable this camera to monitor objects from virtually any distance. Although for indoor use, they can be used outdoors when combined with weatherproof housing. They are considered the most flexible and widely used by professionals for commercial installations be.
Bullet cameras.
Mini cameras are, as the name suggests, contained inside ball-shaped housing.
Most cameras are weatherproof Ball and sealed without the ability to use different lenses. A major advantage of the ball-camera is the small size and integrated design, some are Cameras even in infrared LED future built. simply LED light in the infrared spectrum (not visible to the human eye). This light is lit field of view, so that possible monitoring in complete darkness. This is a great future, but it works only up to a certain distance (usually 10-50 ft. depending on model) Vary simple to install and are designed estheticly bullet cameras good choice for residential and do-it-yourself installations where monitoring objects are within about 25 feet from the camera location (With standard 3.6mm lens).
Board cameras.
Board Cameras are basically fixed lens mounted on a printed circuit board. These cameras can be in a small package packaged (Mini-cameras) or dome (Mini Dome) or simply sold unpackaged, for mounting by the buyer. Either of these lenses in a normal Industry aperture or a "hole" lens of very small aperture. Pinhole lens cameras are often used as a "spy" cameras and may be in a hidden way covert surveillance purposes to be mounted. The most popular examples of covert board are those smoke detector and motion detector cameras.
Since the lenses in board Cameras are pre-assembled, have a fixed orifice and are usually of short focal length (ie wide angle), their flexibility of usefulness is limited. But this type of camera can be a cost effective solution in the right situation, especially in the home environment. We have briefly described most popular types of cameras that can now discus, how and where they mite be used.
Professional types with C / CS-mount lens system usually offer the best performance and many important futures, like lens output, back Light Compensation and many more …
Distance from the object to the surveillance camera is not a problem, so ability to use different lenses, to location-based choose is so important. The installation is somewhat complicated and professional installation strongly recommended. We recommend this type of surveillance cameras for commercial installations.
Most small cameras do not provide a comparison in high resolution and lens selection flexibility, but likely to be weatherproof, some have built-in infrared light and, above all, they are relatively easy to implement. They are usually with 3.6mm lens witch came to be suitable for most standard installations (good for covering small to medium sized rooms or equivalent).
For larger rooms or longer distances, cameras with 6mm or higher lens may be necessary. They are good choice for do-it-yourself installation.
Board cameras in contrast are widely used in covert camera installations, sometimes called a spy camera. Many of those are basically board with built-in transmitter. We can not go into wireless cameras right now, because that would be enough material for completely new products.
Board cameras are sold as pure PCB for installation into hidden camera devices. They are also available in dome housing, how different popular Dome Camera or integrated with smoke detectors, motion detectors, Exit Sign and so on. Most also come with 3.6mm lens although some will be replaced by lens.
During the time, the most practical design dome with its aesthetic appearance, it was added into the environment, especially with drop down sealing, ideal for use in stores, lobbies, gas stations and other public places. Practical solution for covert installation also, Motion and Smoke Detector cameras, they are not absolutely substitute for your security alarm or fire protection. You should always be on the camera's position to be selected (inside / outside), distance from the monitoring object light and budget.
When shopping for security cameras, the customer with the fact that they need to face one or the other option recorder.
The days of well-known CCTV time-lapse recorder are almost over.
Although some customers still prefer this old fashioned recording solution, it is worthwhile invest more money to purchase a good quality digital video recorder (DVR). Digital recorder transfers analog camera video feed in the format and stores them on the hard disk. There are two major types of digital recorders on the market right now.
