CCTV camera technology has greatly improved. Images are sharper, clearer and now support higher frame rates allowing them to record fast moving objects better. Night vision has become so much better, new features like analytics, wdr (wide dynamic range) have made cameras smarter and more powerful. Remote viewing and management together with off site recording now possible even with the entry level systems. Customers are spoilt for choice when it comes to cameras depending on the customer’s needs. HD picture quality is now available from analog systems.

Choosing a Camera System

Most people and businesses choose to skimp out on their cctv solution opting for cheap unknown brands or one time installers with no customer support and after service. What they fail to realise is that cheap is expensive. In the long run a cheap camera kit fails quickly, shoddy installations fail.  When an incident occurs and footage is required, the image is blurry or in some cases there was no hard drive installed. In worse cases the DVR was not recording at all having failed months or weeks before the incident. It is better to spend a little more and have peace of mind, than go cheap and spend more in the end. There is three types of camera technology when choosing a camera system AHD, TVI and IP.


HD-TVI stands for high definition transport video interface. TVI cameras have the longest transmission without signal degradation across both RG59 and CAT5 cabling. Video output quality is great with sharp images up to 1080p where true colors are visible. TVI allows the user to connect to any analog or HD-TVI camera, on any DVR channel, and is the only HD analog format to support IP cameras. Pricing on HD-TVI cameras is great given the outstanding picture quality. The only downside to having a TVI system is that they require a special DVR, but luckily, the DVR does support analog cameras


AHD stands for analog high definition. These cameras can support RG59 and CAT5 cable, but the cables have a low transmission distance. AHD provides good pictures but the images are not as sharp and colors are not as accurate as TVI. AHD cameras have won in the price category, where prices are almost as low as analog cameras.


IP stands for internet protocol. IP cameras use network cable and provide a good solution for projects that require a large number of cameras. IP cameras have higher resolutions than standard analog cameras and provide sharp images at higher resolutions. IP cameras use Ethernet cable to transmit power, video and data. Some downsides of IP cameras is that they require a complex network infrastructure and are very pricey compared to TVI and AHD cameras

When choosing a camera solution for your home or business , several factors need to be considered:

  • What areas do you want to cover? This determines the size of the lens of the camera and the width of the angle.
  • Storage capacity: High definition picture takes a lot of space, newer technologies have come up to solve this issue, but its still an issue.  8 cameras recording continuously in HD on a 1tb hard drive may record for less than a week. A company may need a longer record time.
  • Analytics: More advanced cameras have analytics built in, features like line cross detection, object removal, face detection, wdr and LPR licence plate recognition (used at security gates)
  • Warranty: Check the warranty of the cameras, cheap  mall specials do not have a warranty
  • Night vision: All new cameras have built in night vision, depending on what you want to see and the area. Different cameras have different specs on IR 20m 40m and 80m. Sometimes some extra lighting maybe required.
