Feeling overwhelmed by the vast array of CCTV cameras on the market? We’re here to simplify your choice. Join us as we break down the different types of CCTV cameras to help you make an informed decision.
CCTV cameras can be categorized into four main types based on their housing, image quality, technology, and lens:
Camera Housing: The physical design of a camera, such as dome, bullet, PTZ, and fisheye, determines its suitability for different environments and applications.
Image Quality: Image resolution, measured in megapixels, directly impacts the clarity and detail of the captured footage.
Technology: CCTV cameras can be either analog or IP. IP cameras offer superior image quality, advanced features, and network connectivity.
Lens: The type of lens used affects the field of view and focal length of the camera.
Let’s delve deeper into each category to help you select the perfect CCTV system for your needs.
Image Quality of CCTV Cameras
Image quality, or resolution, is a key feature used to classify different types of CCTV cameras. Image quality is determined by megapixels. The higher the number of pixels in an image, the more detail can be seen.
The most common resolutions available on the market are:
1 Megapixel = (1280*720) or HD
2 Megapixels = (1920*1080) or Full HD
3 Megapixels = 2048*1536
4 Megapixels = 2560*1440
5 Megapixels = 2536*1920
8 Megapixels = 3840*2160 (4K)

HD Analog Cameras:
HD analog, or high-definition closed-circuit television systems, represent a new generation of
analog surveillance cameras. By altering the output signal frequency, these cameras can deliver extremely high-quality images, even up to 8 megapixels. There are various types of HD analog technology, including AHD, HDTVI, HDCVI, and HDSDI.
Network or IP Cameras:
IP cameras are the latest generation of surveillance cameras. As their name suggests, these
cameras utilize digital signals over a network for data transmission. Consequently, they offer high-image quality. Network cameras possess image processing capabilities and various intelligent functions. Additionally, a Network Video Recorder (NVR) is used for recording the captured images.
CCTV Camera Lenses:
Fixed Lens:
Fixed lenses maintain a constant focal length. This means that once installed, the camera’s viewing angle is fixed and cannot be adjusted.
Manually Variable Focal Lens (Vari-focal):
Unlike fixed lenses, vari-focal lenses allow for manual adjustment of the focal length within a specific range. Vari-focal lenses have optical zoom. The greater the focal length, the higher the magnification.
Motorized Variable Focal Lens (Vari-focal-Motorized):
Motorized lenses can have their focal length adjusted remotely. Due to the built-in motor, these lenses are more expensive than others and are very useful for environments with installation constraints.
