Wireless is More Advanced than Wired CCTV Systems

Whilst it is true that wireless CCTV has its advantages and the technology that makes these kinds of systems work is pretty spectacular, wireless CCTV systems are no more popular than they were 10 years ago. There are numerous shortcomings in the technology that may mean that a wireless CCTV system is not appropriate for you. The cameras in a wireless CCTV system are often not as good as wireless systems tend to be aimed at the lower end of the market. They are also prone to interference from mobile phones etc. and are also vulnerable to hackers.

Higher Resolution = Higher Detail in the captured picture

As we are increasingly moving from 1080p to 4k resolutions this is a misconception we come across quite a lot. The answer depends entirely on the type of camera you are buying and the positioning of the camera within your CCTV system. For example, a camera with a wide angle lens may still struggle to capture detailed images of objects in the distance even if they are high resolution cameras. This is due to the spread of pixels increasing as you move away from the camera due to the wide angle lens. Not only this but the amount of storage space a 4k feed takes up is much larger than that of 1080p feeds. We can help you to choose the right camera for your system.

A Low Lux Camera Will Perform Well at Night

Lux figures can be very misleading, although they can be used as a reasonable indicator of how well a camera will perform at night. It should be the case that, the lower the lux number the better the camera will perform in low light situations. However, cameras equipped with infra-red are able to report a lux number of 0 where, in reality, their low light sensitivity may be quite poor. There is also no industry standard for how good the quality of the feed has to be in low light. There are also other factors that could affect the performance of the camera in low light situations.

There are a number of other misconceptions out there about CCTV Cameras. We would be happy to answer any of your questions or queries and help you choose the right set-up for your situation.
