What to Consider When Upgrading Your CCTV Camera
In its most basic form, a CCTV system consists of a camera connected to a recording device that is connected to a viewing device.
When thinking about upgrading a CCTV system you need to consider these basic elements. If cost is not an issue, then this is less of a worry and you can just rip everything existing out and replace it with the latest equipment and cables. If, however, you are working to a budget then it is worth investigating your existing infrastructure, and looking to reuse as much as you can. This will save large amounts on installation costs and potentially speed up the CCTV camera upgrade.
Depending on the age of your system you will have either a coax cable (older) or a structured cable (not so old) connecting your cameras to your recorder. A large part of the cost to install a CCTV system can be taken by the energy required to install cables to each of the cameras. If you can reuse the existing cables very substantial savings can be made when you have a CCTV Camera Upgrade.
I hear you say – If I don’t upgrade the cable won’t I end up with the same quality video as I already have? You would think so – especially if you are reusing ageing coax cable. But surprisingly the answer is no – you can get full HD digital quality images over cables that were installed 30 years ago for analogue use. Manufacturers realised that there were a lot of people who had CCTV and were happy with what it was doing for them and the cost to completely upgrade their entire system was not worth it and would just stay with an OK analogue system. A method of using a standard coax cable originally installed to work with analogue CCTV was developed to carry digital signals over the same cable.
This opened a whole new opportunity to provide some of the latest HD cameras to people who did not want to spend a lot of money on a CCTV Camera Upgrade. These systems are commonly called Turbo HD CCTV.
These systems have continued to be developed and can carry power and data as well as video over a single coax cable. Many of the smart features associated with full IP systems are available and the cameras can be accessed via a PC – on the local network or remotely if required. Also, the system can be viewed via a smartphone. Two very useful features that a CCTV Camera Upgrade would provide that your existing system probably cannot do or doesn’t do very well.
This means that by only changing the camera and the recording device you can dramatically improve the quality and functionality of your system. For most requirements, this option has very few drawbacks and is extremely cost-effective.
While upgrading to HD over coax will bring many improvements to your system to get the latest and greatest technology you would be wise to install a CAT6 cable and have a full IP CCTV system installed. This involves running new cables from the cameras to the recording device. This can always be achieved but will often require remedial works to be carried out – holes will need to be put in walls!
