The terminology and appearance of many CCTV cameras can be confusing. If you choose the wrong cameras, the CCTV system will only be good for observation and have poor image detail.

Take into consideration the following factors before selecting a CCTV Security Camera for your home or office:

1. Types Of Cameras

The most common outdoor cameras are domes, bullets, covert, and PTZ. Other types of cameras include box cameras, spy cams, vehicle and wildlife cams.

Consider the following:

Indoors or outdoors? Indoor cameras cannot be mounted externally, but outdoor cameras can. The external camera must be weatherproof.

Would they be better if they were more visible or discreet? Bullet cameras are visible and can act as a deterrent, whereas dome cameras may be more discrete. The dome cameras are more resistant to vandalism and can be mounted lower.

2. Resolution

The term resolution is used to describe the amount of images that a camera can capture. It is measured in pixels. The more pixels the camera has, the greater the detail it can capture. A higher number of pixels helps digital zooming without causing the image to be blurred.

The resolution of your security camera system is crucial to its overall video quality.

3. Lens

The choice of lens for a CCTV camera is crucial. Wide angle lenses are cameras with a smaller focal length, such as 3.6mm. They have a wider field of view. Lenses with shorter focal lengths can cover large areas, but the detail will be poor.

For capturing more detail at a distance (like gates etc.), always select larger focal length cameras. The field of view is greatly reduced, but the detail will be greater at longer distances.

4. Image Sensor

The image sensor is a crucial component of any good CCTV camera. The image (light) is transmitted through the lens to an image sensor (pixels). The image sensor’s quality will determine the image reproduction in the camera, such as the ability to reproduce colours, black and white tones, or day & night.

Consider a high-quality image sensor, such as Sony Starvis or OmniVision.

5. Night Vision (Infra Red)

Infrared technology is used in most CCTV cameras to capture video even at night. Infrared security cameras are essential for areas with poor lighting at night. The illumination range is the distance that can be seen by an IR camera at night. The distance is measured in metres. Consider cameras that have more IR than the actual area covered. Smart IR cameras with auto-adjustment to prevent overexposure.

6. HD Technology

In the last few years, technology in cameras has evolved quite a bit. HD CCTV cameras with a resolution of 1920 x 1080 pixels are almost five times better than analogue video at 700TV lines.

HD SDI offers broadcast-quality 1080P resolution. Only compatible with RG59 quality coaxial cable.

HD TVI offers 1080P resolutions of very high quality. It can be used with pre-made cables, RG59 coaxial cable, and Cat5 Cabling.

AHD (Analogue HD) offers 1080P resolutions of very high quality. It can be used with pre-made cables, RG59 coaxial cable, and Cat5 Cabling.

AHD, HD TVI, and HD CVI all share similar technologies.

7. Wireless Internet

Wireless and WiFi are terms used to describe systems without cables. You will need to consider the transmission path of the signal and power each camera on your wireless or WiFi system. Line of sight.

Wireless cameras are analogue cameras (which use radio transmission only). HD CCTV cameras are not compatible with this transmission type.

In cctv, the term “WiFi”, is used to describe cameras that use a network. It uses digital radio transmission, but it is also based on radio transmission. WiFi can be used to connect IP Cameras and DVRs for remote access. Ask our technical support or sales team for help. For more info https://allroundsecurity.co.nz/
