A CCTV system is a video system that displays real-time viewing as well as footage playback by strategically placing video cameras around a specific area. CCTV Cameras work by capturing a constant sequence of images that are then transmitted by cable or wirelessly to a display monitor where the sequence of images is demonstrated as video footage.
The two main types of CCTV system
Wired: Cameras and the rest of the system is hard-wired.
Wireless: There are no wires required as the system works on an internet connection
How do Wireless CCTV Cameras work?
CCTV’s work on the principle as any other wireless device. They don’t connect with a wire, but use a short-range signal to connect to a hub or a device.
A wireless camera must maintain a signal connected to your network to record and capture footage, after which it is sent to a receiver that is connected to a built-in storage device or through cloud storage, and offers you 24/7 viewing access no matter where you are.
Benefits and Limitations of Wireless CCTV System
Benefits:
Easy to install / Budget-friendly / Portable / Easy Accessibility
Drawbacks:
Always need an internet connection.
A disrupted signal connection will force the Wireless cameras to retire.
They still need to be plugged into a power socket
Always need to be kept within the range of a central network.
Conclusion
CCTV systems work based on capturing a sequence of images and displaying them as Real-time videos. The two types of CCTV systems are wired and wireless systems. Wireless systems work on the concept of connecting to a signal hub connection and giving you 24/7 viewing.
These systems are best for security, affordability, portability, and accessibility. Therefore, when you are purchasing wireless security systems, go for those that are built to handle your safety concerns and can last for years.
What is CCTV?
CCTV stands for Closed Circuit Television. It is a video system that consists of strategically placed video cameras around an area that records footage, and is then transmitted to a display monitor(s) for real-time viewing as well as footage playback.
A CCTV system therefore refers to all aspects and components that make up the system, such as the camera, wiring, video footage storage (via the cloud or digital video recorder), monitors, access control and general system management.
You would want to use a CCTV system to increase the security of your business premises and have surveillance on key areas at any one time. This would be particularly useful for large premises or one that holds valuable equipment, products or information.
As well as recording video footage, a CCTV system can also notify you if there is activity or movement on a certain camera at a set time. For instance, in the dead of night whilst the business premises in closed and employees have gone home. This notification could indicate that someone may be about or looking to break-in to your site.
Although a CCTV system can be used for the surveillance of on-site activity, during and out of working hours, it can also be used to help identify wanted criminals, as well as act as a deterrent to potential intruders.
How Does CCTV Work?
Want to know the ins and outs of how a CCTV system works? It’s not complicated, but it does vary depending on the type of system you install and the components used. However, the overall process is the same.
Consisting of at least one camera, lens, monitor and recorder, a CCTV system can be scaled up or down depending on the size of area wanting surveillance. CCTV works by the camera or cameras taking a constant sequence of images that are then transmitted by cable or wirelessly (depending on the chosen system type) to the recording device and then on to the display monitor, which enables an individual to see the sequence of images as video footage. Depending on the type of cameras used, they may also have the ability to zoom in and out and rotate 360 degrees.
As mentioned previously, there are many types of CCTV systems with various cameras that have a number of uses, such as night vision, thermal imaging and number plate recognition.
