CCTV Systems Explained

CCTV

CCTV can be another added deterrent against criminals. CCTV has been a common fixture in shops, pubs, car parks and other public places for years. Now, thanks to easier installation and falling prices, it’s becoming an increasingly popular choice for domestic and commercial premises. CCTV is just one line of defence against crime and works best when combined with other measures, such as Intruder Alarms.

Access Control Systems.

Take a look at our guides to intruder alarm types and access control systems to find out more about making your home and work place fully secure.There are plenty of CCTV options if you want to keep an eye on your property.

IP CCTV System

These are cameras that use your network or internet portal to send images to your computer’s router, allowing you to access the footage over the internet from remote locations.

Hard Wired CCTV Cameras

These are the most common types of cameras. Each Camera has a signal cable and power cable connected to it. These cameras can be fitted internally or externally around your premises.

Storing CCTV Images

Most CCTV systems use a PC hard drive or standalone digital video recorder (DVR). The main advantage of PC-connected systems is that they often come with software to view the images. Some DVR-based systems also have this facility. Make sure that your system allows you to store images in a widely used format, such as Mpeg, otherwise there may be problems if images need to be downloaded and viewed on other systems, such as those used by the police. In addition, make sure that if you get a camera that can record high-quality images, the PC or DVR can record them.

Remote Access

Some CCTV systems, such as IP ones, let you check images over the internet using a PC or smartphone. Other options include email or text notifications when cameras are activated.

Night Vision

Monochrome (black and white) CCTV cameras tend to be the most effective in low light, particularly when used with integral infrared illumination – a feature found on some cameras. It’s possible to use CCTV cameras that will film in colour during the day and switch to monochrome when it gets dark. These are called Day/Night cameras and are what we would recommend for most installations.

Motion Detection

Some CCTV cameras have a sensor that turns them on when they detect movement. This can be handy if you want to reduce the amount of footage you’re storing.

CCTV and Privacy

If you’re thinking of getting a CCTV system for the outside of your property, you must comply with privacy laws. This means making sure that your cameras aren’t pointed at public space or other people’s houses or gardens.
