A CCTV security camera is a video camera that transmits a video signal to a specific place. This form of camera shows live footage of the area the device is pointed at on a monitor. The cameras can also be combined with a network video recorder or digital video recorder to store the recorded video footage for viewing later. Should any incident happen, you can legally use these cameras later in court. Therefore, these cameras serve as a deterrent to most criminals. 

How do CCTV Cameras Work?

These cameras are installed in specific locations of extreme importance. Once installed, they monitor the targeted areas and record the video footage. These videos can then be stored in a physical device or cloud. Regardless of where it is stored, the authorized user can access this footage to view it at a later date. Many types of CCTV cameras can also be watched live on a monitor as the video is stored.

There are many types of CCTV cameras. Their types vary depending on their specific function and their applications. That said, some of the common types of CCTV are as follows:

Dome Camera

This type of camera is shaped like a dome and is rather discreet, making it ideal for homes and businesses. This type of camera features a wide angle and is widely used in residential and retail settings.

Bullet Camera

Bullet cameras are cylindrical and are typically weatherproof. Therefore, they are typically used for outdoor monitoring. That said, this type of camera can also be used indoors. Unlike dome cameras, they are rather visible, making them ideal for deterring crimes. Therefore, they are ideal for usage in parking lots, entrances, and outdoor areas. 

Pan-tilt-zoom (PTZ) Camera

As their name suggests, PTZ cameras can pan, tilt, and zoom remotely, along with horizontal and vertical rotations. Therefore, these cameras offer flexible coverage. Because of these reasons, PTZ cameras are commonly used in stadiums, parking lots, or industrial sites.

IP Camera

These cameras transmit videos over an IP network. Therefore, they facilitate remote access and scalability. Furthermore, they also offer advanced features and high-resolution images. Therefore, this type of camera is ideal for both businesses and homes.
