When it comes down to getting the right CCTV for your business or home, look no further. We are an authorized and certified installer of the number one (#1) CCTV brand in the world – HIKVISION

There are 2 main types of CCTV options – Analogue and IP.

Which solution will best suit me?

Below are a few basics about each solution, however, to answer this question we need to determine what is more important – price or video quality. IP has much higher video quality however a higher price tag as well. THD (Turbo HD) analogue has quality up to 2MP and a lower price tag. A 16-channel solution will work out about R4000 more for the basic IP solution vs the 16 channel THD 1080p analogue solution.


In the past, analogue systems did not have such great quality picture, yet was still popular due to the low cost of the cameras. However, the latest analogue technology known simply as Turbo HD or HD over coax provides a high-quality picture (HD 720 and 1080P AVAILABLE). It is now still as popular as ever, not only because of quality but pricing as well.

Installation is simple and easy, using RG-59 powax cable. It can be installed over a distance of 500m without the use of any signal boosters or repeaters etc.

Some of the great benefits of the Hikvision Turbo HD solution include:

Low-cost solution,

low cost when upgrading from an older analogue solution as the existing cameras and cabling, if any, can still be used (however to get the best from your solution may be best to replace the cameras to enable full HD quality)

Fast transmission of HD video over long distances up to 1080P (equivalent to a 2MP IP camera)

The DVR (Digital Video Recorder) is small and compact a can be easily installed.

Hard drives – we recommend using only surveillance drives. The size of the drive depends on a few factors:

How long do you want to record, what type of camera, motion detection recording or 24/7 recording and how many cameras are connected.

Due to the fact that there are so many variants of CCTV solutions on the market, not just makes, brands but also types of cameras, indoor/outdoor, bullet type/dome, getting the right solution should not be tiresome. We at POS & CCTV Technologies can assist you with the right solution right from the start.


What is an IP camera?
An IP camera is the evolution from analogue signal to a digital signal. IP cameras are based on the same networking technology used to connect computers (PC’s) to a network switch. The term IP camera is an acronym for Internet Protocol. IP cameras are also commonly referred to as HD cameras, High Definition cameras, Megapixel Cameras. Megapixel means millions of pixels.

IP cameras achieve a higher resolution than analogue cameras. The more pixels in a picture allow for a sharper, clearer image

What is Aspect Ratio?
Aspect ratio is the Vertical and the horizontal resolution of an image. The higher the pixels the bigger the image will be. High Definition TVs now broadcast in 16:9 aspect ratio where the older Standard Definition TVs used to broadcast in 4:3.

Video Compression and how its affects image quality
IP cameras run on a compression called H.264. H.264 is the evolution of Mpeg4 and allows for multiple Megapixel Cameras to record to a single NVR (Network Video Recorder) and run multiple cameras on a network without losing picture quality. H.264 profile works by only logging the changes in the P-frame and I-frame of images. The B-frame is completely ignored thus allowing for lower latency, lower bandwidth and increased recording space. H.264 can be as much as 60% more efficient over the previous Mpeg 4 codec. The next standard of video encoding will be H.265 or Hvec which will allow for encoding of higher resolution cameras i.e 8 Megapixel – 29 Megapixel at a lower bandwidth.

How will IP cameras benefit me?
Because IP cameras are based on a digital IP system this allows for higher image resolutions and clearer images. The installer can also access the camera directly and setup the camera from a PC in the control room.
Most IP cameras can have an SD card slot where recording can take place on the camera, thus allowing for a failover of recording should the server be compromised. IP cameras that have audio can also record audio over a single cable.
Installations are also minimized due to IP Cameras only needing 1 cable for power, video streams, audio and any i/o switching.
With the advent of High Definition cameras over Analogue Cable (HDTVI/HDCVI) it has allowed for entry level installation of HD cameras. The limitation of this technology is the highest resolution it can record is 2 Megapixel. All audio, power, I/O have to be run on separate cables.
