How CCTV works

Wireless home CCTV systems

Images can be transmitted using analogue or digital technology. Wireless systems can suffer from interference from devices such as routers, cordless phones and microwaves, and can be blocked by heavy masonry or metal objects.

Outdoor home CCTV cameras

If you’re using CCTV cameras outside, make sure they’re weatherproof – an IP (International Protection) rating of 66 is recommended. 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 can be accessed for maintenance and cleaning.

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.

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 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.

Remote access

Some home CCTV systems let you check images over the internet using a PC or smart phone. 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.

Home CCTV cameras with 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 footage resolution

High-quality images are needed if CCTV footage is to be used as evidence in court. However, for the best detail a high resolution is required, and this can take up a lot of storage space. The minimum recommended resolution is 352x288 pixels. Also ensure that the date and time used to ‘tag’ images is set accurately.

CCTV and Privacy laws

If you’re thinking of getting a home 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. 

It’s a good idea to discuss any CCTV plans with your neighbours first – some people told us that they share a system with their neighbours, which might be one way to cut down on costs.

CCTV is just one line of defence against crime, and works best when combined with other measures, such as door and window locks, keeping trees and foliage cut back, security lights and a burglar alarm. 

The Benefits of installing CCTV Camera Systems.

Obviously, the biggest advantage is the security aspects that both CCTV can bring your company. CCTV will allow you to keep a track on people within your store to ensure that they do not shoplift, and if they do then you have proof that they attempted to do it. This of course will result in a much greater chance of successful prosecution. Alarms will stop people entering your building out of hours. If the alarm is triggered then you will be contacted, as well as the police in order to deal with the situation. If any property was taken during the break in, then the CCTV will be there to get a recording of the people that entered, once again maximising the chances of bringing a successful prosecution, and of course getting your property back. All together this should help you save money in the long run. There has also been a big increase on domestic properties having CCTV installed nowadays as well. It is the best way of protecting your property from opportunist burglaries and vandalism. The Systems act as a deterrent for crime, If people see that these are in place then they will be much less willing to commit crime against that property. In residential premises, if you have a CCTV Camera in place, you will find that you feel much safer in your property, this will give peace of mind to the homeowner.

As you can see, the benefits of CCTV and alarms are far reaching, in this day and age it IS the best way to protect your property, whether you own a residential or commercial premises.

Taking advantage of your existing coax cable and power makes this transition simple and effective. You can enjoy 128 times higher resolution than your standard analog cameras and take advantage of the digital zoom capabilities provided by the megapixel video. It has never been easier to upgrade your existing system.
