higher the megapixel number, combined with a suitable camera location, the more detail and clarity the camera can capture. The more detail required by the client, the higher the megapixel count of the camera should be.
The minimal resolution is generally accepted at 2 megapixel, with 5 and 8 megapixel becoming more commonplace.
How will the light levels affect the CCTV recording?
It is important to place cameras effectively according to lighting conditions, especially with external cameras. Varying amounts of sunlight and limited daylight during the darker months may determine where the cameras are positioned. Other factors to consider include background glare from security lighting, sun or light reflection from windows facing the site.
For viewing at night time when there is no supplementary light, a camera, just like human vision, cannot see anything. The majority of cameras, therefore, are now equipped with either Infrared LEDs, which will produce a mono image at night time up to a certain distance, or White LEDs which will produce a colour image up to a certain distance. If the cameras can be assisted further with security lighting this will improve the images captured during the night time hours.
Industry Event Tackling critical issues affecting electrical products
The 2024 Electrical Product Safety Conference brought together experts and industry leaders to examine the latest crucial issues impacting the safety of electrical products.
A
major focus of the event was the new UK government’s approach to ambitious product safety targets highlighted in the 2024 King’s Speech, and how it will advance the Product Regulation and Metrology Bill.
In her address to the conference, Lesley Rudd, chief executive of Electrical Safety First, highlighted that the Bill has “the potential to be
revolutionary in many ways”. She said: “It could start to finally address the twin threats of unsafe e-bikes and third-party sellers selling dangerous goods online.
“Our goal is to ensure this legislation is robust enough, leaving no gaps for future bad operators or dangerous products when it comes to consumer safety and protections.”
Arming the UK with the tools to tackle safety challenges
The potential impact of the Bill was also addressed in the opening keynote speech from Justin Madders, Minister for Employment Rights, Competition and Markets at the Department for Business and Trade, who told delegates it would “give us the power we need to keep pace with the technology revolution”.
He said: “The Bill arms the UK with the tools

to tackle safety challenges and is the vehicle to enable us to handle new challenges. It is important that we deliver change as the world is getting more complicated. Government and industry can be most effective when they work together.
“Over the last decade and a half, regulation has been a dirty word. But regulation supports growth and supports businesses to bring new products to market.”
The changing nature of global markets was also under the spotlight with a look at the potential impacts of significant changes to online marketplace regulations. And the day was rounded off with a glimpse into a changing world – including the rise of connected products, digital product data, the race to net zero and how to empower consumers.

Understanding the requirements As the above demonstrates there are a number of factors to consider when specifying a CCTV system and cameras, but most important is the need to fully understand the client’s requirements
and expectations. Then, by providing them with the full picture as far as requirements, features and options are concerned, the installer may well be in a good position to upsell to a higher specification system.
