CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV camera system is being widely employed as a security system for surveillance in offices as well as homes. It is used for monitoring purposes to keep a close vigil. Not only in closed or private places; CCTV camera system extends as a security system in public and crowded places like traffic intersections, malls, shops, etc. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere, Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.
Dome Cameras are named after their shape is typically used for indoor security systems. The dome shape of these cameras allows them to be inconspicuous because it is hard to tell the direction the cameras are facing; however, being still visible to the eyes. They are widely used in retail spaces. Since they are installed on the ceiling of the room, they are mostly vandal proof. Some dome cameras are designed with infrared illuminators, which enable them to capture videos in low light conditions.
Bullet Cameras have a long and tapered cylinder-like design that resembles an oversized ammo cartridge. They are mostly used outdoors, especially in areas where long viewing is necessary. However, they can be used indoors where the long viewing is required, like backyards and parking lots. They are installed inside protective casings and are typically weatherproof. Most bullet cameras come with a fixed length that allows the angle of view of up to 80 degrees. A bullet camera is usually fitted with a fixed or varifocal lens.
C-Mount CCTV Camera can use detachable lenses to suit different purposes. Typically, a CCTV Camera can record up to 35 feet; however, if you need surveillance beyond this distance, a C-Mount Camera with a particular lens can achieve that purpose. A varifocal lens is often used to fine-tune focal distance and the angle of view. They can be zoomed in and out without losing focus.
These types of CCTV cameras can be used in both poorly lit and standard environments. Mostly used outdoors, these surveillance units have a wide dynamic range and can function under direct sunlight, glare, or reflections. They are used 24×7, and these cameras do not require an infrared illuminator as they come with an extra sensitive imagining chip, which is used in the dark.
It is possible to pan, tilt, and zoom PTZ cameras. It gives a surveillance operator the freedom to pan, tilt, and zooms the lens. You can manually control these cameras or program them to follow an accurate view of things. Since these cameras can be monitored using live controls, they are employed in highly sensitive zones where live monitoring is required.
HD CCTV Cameras can record at high frame rates and at HD quality, which is comparatively at a higher resolution than other CCTV Cameras. This type of camera can capture finer details while giving the operator the option to zoom in without losing picture quality.
When we need to see what’s happening in the dark, then a night-vision CCTV camera can help us. It can see when lighting is poor or absolute darkness. It technology behind this is Infrared LEDs. Do you need this kind of CCTV Camera?
The IP camera can transmit recordings over the internet. It may or may not require a wire connection. Yes, it also works on wireless technology. In comparison to the analog camera, it is easy to install. It is possible to send recording over a far distance without requiring any power boost using a cable
We have talked about the wireless IP camera. Other types of CCTV cameras are also available that work on wireless technology. Flexible installation is one of the primary benefits.There are several CCTV camera types with unique features for different purposes.
