Welcome to our monthly news roundup for Businesses and Homeowners across the North and beyond.

This month: HD-CCTV


Many customers have High Definition TV in their homes and are expecting to see the same level of picture quality from a CCTV system. Well, we can now bring that to you easily and cost effectively thanks to HD-SDI. Briefly, the benefits of HD-SDI CCTV are high definition images (typically 4-5 times higher than standard analogue), making it easier to identify individuals. HD-SDI can easily be used in tandem with existing analogue cameras.


A frame of CCTV footage is made up of pixels. Any picture with over 1 million pixels is classed as a Megapixel image and can be referred to as High Definition (HD). HD Equipment typically has one of two resolutions: 720P and 1080P. 720 or 1080 refers to the number of pixels in a vertical line that make up the picture. We offer the 1080P resolution which can be switched to 720P to allow longer recording times if required.

Megapixel CCTV has been possible for some time over IP CCTV networks. So HD-SDI is not the only way to achieve it, but its arrival makes Megapixel CCTV simple and affordable. IP CCTV is more prevalent in new builds (where there is no issue of replacing existing coaxial cable) and large installations where budget is less of an issue.


You have two basic options when choosing an HD-SDI CCTV – a full HD-SDI system, or a Hybrid system combining HD-SDI with Analogue. Some customers – especially those with an existing analogue CCTV system – may feel that a few HD-SDI cameras in key positions such as external doors will suffice.

To view HD-SDI you will need a recorder that has HD-SDI camera inputs and HD-SDI cameras. To also fully appreciate the definition you will need a HD monitor to view the images.

We can also provide 180deg and 360deg cameras which are perfect for covering surveillance of large internal or external areas. Ideal for applications such as: retail, warehouses, hotels, hospitals, schools, car parks, petrol stations.
