Benefits of  a CCTV Camera Upgrade

Firstly, you must ask yourself why you need CCTV Camera Upgrade.  This could be for a number of reasons.  Like many electronic systems upgrading or replacing is inevitable – parts start to fail, the system becomes unreliable, passwords get lost, the system cannot be expanded, some cameras have poor images, some images are black and white, some cameras are not in focus – the list goes on.  The latest CCTV systems have superior image quality and a host of features that your old system probably does not have.  Upgrading the system will benefit your organisation and provide better results.

Below we take a look at some of the benefits that come with a CCTV Camera Upgrade:

  • Improved image quality: Upgrading to cameras that have higher resolution provides clearer and more detailed images, which allows for improved identification of individuals and objects that are captured on camera.
  • Better night vision: As technology evolves, upgrading to cameras with greater and more advanced night vision capabilities, such as infrared (IR) or thermal imaging, will provide you with clearer images even in complete darkness, enhancing the security of the area you are monitoring.
  • Greater coverage: Upgrading can also mean adding cameras with wider angles which provides increased coverage of the monitored area, reducing blind spots and enhancing your overall security.
  • Remote monitoring: By upgrading to cameras with remote access and monitoring capabilities, you are able to access real-time monitoring of the area from a remote location, which offers better flexibility, security and convenience.
  • Advanced features: Upgrading to cameras with advanced features, such as motion detection, facial recognition, or license plate recognition, can provide additional security and intelligence capabilities.

Disadvantages of CCTV Camera Upgrade

The cost of upgrading CCTV Cameras may be a concern but the cost of not upgrading may be even greater in terms of lost or damaged property, liability claims, or other security risks.

Cost may be a disadvantage however in time, it is still important to have a CCTV Camera Upgrade. Upgrading cameras can provide numerous benefits, such as improved image quality, better night vision, increased coverage, and advanced features like motion detection and facial recognition. These benefits can enhance the effectiveness and efficiency of the surveillance system, providing better security for the monitored area and greater peace of mind.

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!

When to have a CCTV Camera Upgrade

It is important to upgrade your CCTV camera when it begins to fail to meet your expectations. This could be due to the availability of superior alternatives in the market, or the device reaching the end of its lifespan.

The lifespan of different components in a security system can vary, with analogue cameras typically lasting 5-10 years, DVRs lasting 5-7 years, NVRs lasting 5 years, and IP cameras lasting 6-10 years. In some cases, replacing an entire security system is usually unnecessary, as coaxial and ethernet cables are designed to outlast the connected systems. Instead, minor upgrades to the recorder or cameras can deliver top-quality performance.

It is always a good idea to combine other works with an upgrade of a system whenever possible.  If you are carrying out renovations to your building or are installing a new network for other reasons it is worth considering what cables should go where at that stage – this will cost relatively little to do in conjunction with other works but will save a considerable sum if you were to do it at a later date.

What are the advantages of upgrading the cabling to Cat 6 or Fibre?

Essentially it comes down to bandwidth.  The more bandwidth you have the more data you can move down a cable more quickly.  Why is this important?  8K is the reason for this – the bandwidth required to give the ultra HD images some cameras are now capable of is huge and the latest Cat 6 cables are required to enable this huge throughput.  If you require ultra HD cameras, then a new cable is a must.

Having said this 4K images over coax is possible and for most applications, this is more than adequate.

In short, it is ideal to upgrade the entire system but if it is most cost-effective to reuse existing cables then real benefits can still be obtained when doing a CCTV Camera Upgrade.

Frequently Asked Questions – CCTV Camera Upgrades

Q. When should I upgrade my CCTV cameras?

When the system starts failing to meet your expectations – poor image quality, unreliable recording, lost passwords, or components reaching the end of their typical lifespan (analogue cameras around 5 to 10 years, DVRs 5 to 7 years, NVRs around 5 years, IP cameras 6 to 10 years).

Q. Can I reuse my existing CCTV cabling when I upgrade?

Often, yes. Coaxial and structured cabling are designed to outlast the connected equipment, so in many cases you can upgrade the cameras or recorder while keeping the existing cable runs, which saves significantly on installation cost.

Q. Do I need new cabling for 4K or 8K cameras?

4K images can usually run over existing coax cable and are adequate for most applications. 8K and other ultra-HD footage need much higher bandwidth, so Cat 6 cabling is required to support that throughput.

Q. What are the main benefits of upgrading CCTV cameras?

Improved image quality and identification, better night vision, wider coverage, and advanced features such as motion detection and facial recognition that older systems typically lack.

Q. Is upgrading CCTV cameras expensive?

Cost is a real factor, but the cost of not upgrading, through lost or damaged property, liability claims or other security risks, can be greater. Reusing existing cabling where possible is the main way to keep upgrade costs down.

Q. Should I combine a CCTV upgrade with other building works?

Yes, where possible. If you are renovating or installing new network infrastructure anyway, planning cable routes for a CCTV upgrade at the same time costs relatively little extra and avoids repeating disruptive work later.
