What You Should Consider before Buying a CCTV Camera There are several important factors for consideration when you buy a new CCTV camera, most of which are related to the basic hardware components; thus, understanding such components and their influence on the CCTV camera’s performance is an integral to any shopper. Lens The lens collects light for the sensor. Whatever you see or is recorded on the DVR is coming through the lens. As the lens dictates focus, it’s responsible for determining the distance at which a face becomes recognizable or a car’s number plate becomes readable. In lots of cases, using a better lens is more useful than using a higher output resolution, given that input dictates output, and lens dictates input. Also consider purchasing a zoom lens, which can really come in handy when’re analyzing video recordings that could contain critical information.

Short Course on Security – What You Need To Know
There are two things you should think of when choosing a CCTV camera based on its sensor – type and size. In most cases, CCTV sensors are CMOS or CCD. CMOS is not as expensive as CCD and consumes less power too; however, as it is less sensitive, the quality of images it produces is lower as well. In terms of size, the bigger the sensor, the more light it can process, leading to a better quality image. The two common sizes CCTV camera sensors are sold in these days are 1/4 inch (measures 3.2 mm by 2.4 mm) and 1/3 inch (measures 4.8 mm by 3.6 mm. Output Resolution The number of horizontal lines of TV resolution CCTV cameras can output – also known as their TVL – is one common specification for these devices. Some experts say this should be at least 420TVL, but this is not true for all cases. A high resolution is great to have, but remember that output depends on input, so unless the lens and sensor can match the output resolution, which depends on the DSP, the extra resolution is of no use. What really matters is that there is enough resolution to clearly display any image produced by the camera. Types > Bullet Bullet cameras are cylindrical in shape and are usually used in environments in which discretion is important, but it is unnecessary to install the camera permanently in a protective dome. They are just great for service areas as well as shops where the staff should be monitored. > Dome A CCTV dome camera is the ideal choice for surveillance because it doesn’t only protect itself from vandals, but it also offers a degree of security because it’s usually impossible to tell where the device is pointed. > IR Day/Night Although obvious in appearance, these IR day/night cameras can provide 24-hour outdoor coverage under any lighting condition. They come up with colour images during the day and shift to black and white for infrared viewing during night time. It won’t be that simple indeed, buying the right CCTV camera. But this information can give you a good headstart.
