Just What Is CCTV and How Can It Benefit Me

Reading Time: 4 mins

CCTV (Closed Circuit Television) is a system that allows you to monitor and record footage from cameras. A closed-loop is a term for a large screen TV, which could describe what you see on the TV at home.The DVD player connected to the home TV is a closed-loop device, so people can tune in to the same TV signal and watch and listen.

CCTV is used in areas where security is of paramount importance, such as schools, hospitals and police stations. In the early 1960s and 1970s, CCTV was very expensive and large and private users could not or did not need such luxury. The cameras and CCTV systems are also located in closed and open circuits, meaning that you can be seen by anyone. Closed circuits can also be viewed from a distance of up to 30 meters from the camera.


Security Conscious

We are a paranoid nation and security conscious, and CCTV is everywhere and on every corner. It is estimated that there are more than 1.5 million CCTV cameras in the U.K alone.


Protecting Your Business

Protecting your business and your employees are the norm today, and CCTV plays a key role in helping business owners monitor all they need, from criminal activity to making sure that a business is running smoothly, avoiding accidents at the warehouse. There are a number of factors to consider when choosing a CCTV solution for your home or business, and sometimes it really isn’t worth doing without.

Before we go into the more technical information, you have to take into account the fact that a lot of technology is available and that a customer’s privacy and security is vital. It’s also worth noting that security CCTV should be fitted by experts, such as the Leeds based CCTV Direct, who with the wealth of experience they have would supply an accurate system for your home or business protection.


Digital Cable

You can plug a digital cable into your network via two different types of cable – analogue and digital – where analogue is the most traditional cable, and both offer almost the same image quality.

The digital way is the best, but the negative is the price – digital cameras are currently significantly more expensive than analogue cameras. The power required by a conventional analogue camera cannot be easily shifted and must be connected to the desired cable. Plug it into a nearby network socket and you can move the network sockets to move your camera as you like.


High Definition

Next, you have to bring it to High Definition and insert the default definition, and then you are in a whole new league. The default definition can now be 720TVL (TV line), and can be up to 720p, which is very high-quality images, but not as good as 1080 and higher.

The price of HD is somewhat high, as it does the work of five standard definition cameras, but the quality really does speak for itself. Remember, certain shots can be inadmissible in court if you cannot see faces clearly enough.


Infra Red-Lighting

The last consideration is exterior lighting, and safety lighting is something to be pointed out. There are some cameras with built-in infrared light, but they need some light to work, and there are several ways to do this. By default, most of them move up to 10-15 meters, but if you need more visibility in the dark, an external infrared ring can be added to boost performance. This is useful when the camera is supposed to protect areas that are normally dark and a street light somewhere nearby can provide enough light to make it work properly.

This acts as a huge deterrent for criminals who do not like to set themselves up when they try to break into your home. Throw a few external lights into the mix to deter criminals and also provide enough light for the camera to see clearly at night. This is where the clever stuff happens, and you can be as simple or complex as you want if your budget allows it. DVR (digital video recorder) is the main node of the CCTV recording line and here you can cable your CCTV camera.

It connects constantly until the hard drive is full, and then starts overwriting the footage, then reconnecting and overwriting everything again.


Modern DVR Devices

Most modern DVR devices are connected to a network, so you can monitor the camera and play footage from a connected computer or on your smartphone. You can also set predefined patterns for use: at certain times of day, a camera can pan in a certain direction or instruct it to follow people. The use of such technology will track people and can even trigger an alarm! Surveillance of cameras can be time-consuming, but advanced users can detect camera movements to save space and make it easier to locate an incident.

It is great to capture events, but it is also useful for other purposes, such as security, monitoring or even as an alarm system.

In the security industry, alarm receiving centres are used to remotely monitor 24/7/365. The system is connected to the reception centre to contact the relevant authorities in the case of a situation and even to talk to criminals over local loudspeakers. It can also be monitored in real-time – using a mobile phone, tablet or a computer.

All in all, a CCTV system is a great addition for your home or business and can be key in keeping everything secure. Hopefully the above has shed some light on the CCTV industry and has given you something to think over.
