When we install a CCTV system we always ensure they are fully fit for purpose. By identifying your exact needs and undertaking a full building survey we can be confident in the fact that your CCTV is performing the right function for you..
Sadly though, not every company shares our ethos, and sometimes we see CCTV systems that do not perform the function they’ve been bought for.
One of the fundamental flaws we see with CCTV installations is the wrong camera lense is chosen..
By choosing the wrong lense you often find subjects are too small to recognise. This can lead to detection problems. This problem is especially risky in older cameras where you cannot electronically zoom in. If you aren’t using a HD camera your CCTV pictures average around 40 thousand pixels each. Compare this to the 10mpx you find on high end digital cameras and you see the risks associated with having the wrong lense.
As you can see in the image below image, the Home Office recommends at least 50% screen coverage to be able to properly identify with a high degree of certainty whether you have seen the individual before.
If you are unable to properly identify your subject this can lead to obvious issues if the worst is to happen, so it is important your CCTV installation is properly up to date. We will be happy to listen to any concerns you may have, and assist in allowing to feel confident in your Home or Business CCTV.
Sometimes we hear from customers with brand new systems who still aren’t getting the picture and clarity they desire. This occurs when the cameras aren’t positioned correctly, as even the best quality CCTV cameras need to be positioned correctly to get maximum use of their capability.
