How CCTV works

CCTV (Closed-Circuit Television) surveillance is a widely used tool for enhancing security in a variety of locations, from homes and businesses to public spaces. CCTV surveillance systems allow the recording of images and sound within defined areas, facilitating real-time monitoring and data archiving. In this article, we will look at how a CCTV surveillance system works.

Surveillance cameras ?

The basic components of a CCTV system are the cameras. Surveillance cameras capture images and sound from specific areas and transmit them to a central recording device. There are several types of surveillance cameras, including fixed cameras, pan-tilt-zoom cameras, colour cameras, black-and-white cameras, thermal cameras and more. Each type of camera serves a specific surveillance need.

Image processing ?

CCTV cameras record images of their surroundings and transmit them to an image processing system. This system analyses the images and performs tasks such as motion detection, object or person recognition, zooming and focusing. Image processing plays a vital role in extracting valuable information from the recorded data.

Data storage and archiving ?

After image processing, data is stored on media devices such as hard drives, memory cards or in the cloud. Data storage is crucial as it allows the recordings to be archived and accessed in the future. The duration of data storage can vary depending on surveillance requirements and system resources.

Monitoring and playback

Monitoring, Footage, Playback?

CCTV data can be monitored in real time by operators at a control centre or remotely. Operators can view events as they unfold and react if necessary. In addition, recorded data can be played back for event analysis, dispute resolution or as evidence in criminal investigations.

Networking and remote access

Many CCTV systems are networked, allowing remote access to data. This means that users can monitor their systems from any location using devices such as smartphones, tablets or computers. This adds flexibility and accessibility to CCTV surveillance.

IP cameras and the bottom line

Modern surveillance systems often use IP (Internet Protocol) cameras. These cameras connect to the Internet, allowing real-time transmission of images and sound. IP-based systems are more advanced and offer additional features such as behavioural analysis or facial recognition.
CCTV surveillance systems are extremely valuable tools for improving security and surveillance in a variety of locations. They work by collecting images and sound from cameras, processing the data, storing it, enabling live monitoring and providing remote access to the data. As technology continues to advance, CCTV surveillance systems are becoming more sophisticated and effective. It is worth investing in this technology to increase security in various aspects of life.

What is its mechanism? The main lock contains bolts (also called pins) that can be extended in 3 directions. Their number affects safety, but also the price, because the more of them, the more difficult it is to force the door. The minimum number is 4, and the best models have up to 14 bolts. The lock, like the hinges, should have an addition on the outside
