CCTV Overview

CCTV systems have 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 security-conscious homeowners.

However, CCTV is not for everyone – we estimate that less then 20% of UK home owners have installed CCTV and/or a wireless camera (either indoors or outside).

How home security cameras work

Wired home security cameras

These are the most common and cheapest type of camera, where a wire connects directly from the camera to the monitor. The downside is that the wires, including extension cables and connectors, can be difficult to install.

Wireless home security cameras

With this type of system, cameras transmit images to your computer, tablet or mobile phone, using analogue or digital technology. Many smart security cameras link to an app that you can use to monitor your home while you’re out and about.

Digital cameras are generally higher quality, but more expensive.

Wireless systems can suffer interference from devices such as routers, cordless phones and microwaves, and can be blocked by heavy masonry or metal objects. Your filming may also be interrupted if your internet connection is lost.  Don’t miss our wireless security camera system reviews to find out which models we recommend.

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

Outdoor home CCTV cameras

If you’re using CCTV cameras outside, make sure they’re weatherproof and have the recommended IP rating of 66.

Wireless cameras are available, but you’ll still have to run a cable to a power source. Position cameras where they can’t be tampered with, but are accessible for maintenance and cleaning. You can buy vandal-proof cameras, but these tend to cost more.

Indoor home CCTV cameras

Indoor CCTV cameras come in three types: wired, wireless, and powerline networked (these plug into your electrical sockets and transmit images to a storage device). Wireless cameras are not recommended inside the home unless the signal can be encrypted, as anyone within range and using a suitable receiver would be able to view the images.

Home security cameras footage resolution

CCTV camera resolution is measured in lines – the higher this is, the sharper the image will be.  Image quality is also linked to the size and type of chip the camera uses.

Generally speaking, smaller CMOS chips are lower quality than larger CCD ones, such as 1/4″ and 1/3″.  Cameras with tiny chips also tend to be able to pick up less light, and therefore produce lower-quality images in low light. The light sensitively is measured in lux, which can range from 130,000 to 0.001 lux. The lower the lux, the better the camera will be at recording when there isn’t a lot of light.

You’ll need high-quality images – sufficiently clear for someone to be identified – if CCTV footage is to be used as evidence in court. However, for the best detail, you need a high resolution – this tends to make the camera more expensive, and can take up a lot of storage space. Also make sure the date and time used to ‘tag’ images are set accurately.

House security camera features

Storing CCTV images

Most home 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 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 is able to record them.

Remote access

Some home 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.

Motion detection

Some CCTV cameras have a sensor that turns them on when they detect movement. cctv, cctv systems, direct cctv, home security, home cctvThis 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 home CCTV system for the outside of your property, you must comply with privacy laws. View our Home CCTV Systems Blog  for an overview of the ICO’s recommendations in the UK regarding CCTV & Privacy.

This means making sure that your cameras aren’t pointed at public spaces, or other people’s houses or gardens. It’s a good idea to discuss any CCTV plans with your neighbours first – some customers share a system with their neighbours, which might be one way to cut costs.
