Here are different types of CCTV Cameras:
- Wireless CCTV Cameras
Wireless security cameras are CCTV cameras that pass a video and audio signal to a wireless receiver through a radio band. Wireless CCTV cameras are very reliable, appropriate and convenient to check footage, through your monitor or receiver, you’ll have an easy link to access all of your image or recorded footages.
There are different wireless devices which is very useful in a wireless installation like wireless IP cameras, Wireless NVRs and repeaters also.
Benefits of Wireless cameras:
- Easy to Install
- Faster accessible
- PTZ Cameras
PTZ Security Cameras allow you to control the pan, tilt and zoom operations of the camera lens remotely or through surveillance DVR. PTZ Cameras are very flexible and also have the ability to move up, down, right, left, and even zoom
They are mostly used for outdoor, as their movement axis allows you to have a high range because they can focus on different angles, high power zoom, night vision, and high-quality recordings.

- Powerful zoom and autofocus
- Pan and tilt rotation
- Easy tracking
- Bullet Camera
Bullet cameras are long and cylindrical in shape. This cameras are ideal for outdoor use. Bullet camera strength lie specifically in applications which require long distance viewing. Installed within protective casings, the cameras are protected against dirt, dust& other natural elements.
Benefits of bullet cameras:
- High-quality image resolution
- Adaptability – can use indoors and outdoors
- Compact size aids installation
- Day Night Camera
Day and Night cameras are Capable of working in both normal and poorly LIT environments, these cameras benefit from not requiring inbuilt infrared illuminators as they can capture clear video images in the dark with their extra sensitive imaging chips. For this reason, these cameras are very useful and effective for outdoor surveillance applications.
Benefits of day/night cameras:
- Wide variety of sizes available
- Record in both color and black & white.
- Infrared capability
- IP Cameras
The IP (infrared) camera is not a specific camera model. IP technology is found in different models of security cameras such as the bullet camera, dome camera, and speed dome.
These models of security cameras fall into two types:
- Wired IP cameras: these are usually called the external IP camera which is similar to a bullet or dome cameras, these have a high value and have high resolutions with megapixel quality.
- Wireless IP cameras: The wireless IP camera looks similar to the image on the side and moves around looking like a little robot.
- HD CCTV Cameras
HD CCTV is (High Definition CCTV) an open industrial standard for transmitting high-definition digital video over point-to-point coaxial cable links for video surveillance application without any sort of compression. Uncompressed videos provide high-quality result so it generates output in HD i.e. high quality.
The main advantage of HD CCTV is that it can provide very clear and higher resolution images because there are more pixels available
Benefits of HD CCTV Cameras:
- Easy to Install
- live views, with immediate
- Analog CCTV camera:
CCTV cameras are a type of security camera that uses an analog video signal (CVBS / Composite Video Baseband Signal) to capture video surveillance footage. Analog CCTV cameras are hard-wired to the surveillance DVRs.
These cameras are firstly beginning with a CCD sensor and then digitizes the image for processing. But before it can transmit the video, it needs to convert it back to analog so it can be received by an analog device, such as a video monitor or recorder.
- AHD Cameras
AHD CCTV (analog high definition CCTV) video surveillance standard that uses coaxial cable to transmit HD video from security cameras to DVRs. AHD supports 720p and 1080p HD video resolutions.
AHD Cameras have some of the advantages like High resolution: Advanced signal filtering, 3D noise reduction, higher image resolution, better image reproduction. Long range transmission distance with very affordable price.
