Access Control & Security Cabling
With crime a constant threat to our way of life, we want to feel more secure in our homes and businesses. And, thanks to the rapid growth of technology, closed-circuit television (CCTV) is making us safer than ever. You’re likely to be interested in getting on board with the CCTV revolution, so it’s time to take a look at the principles of CCTV.
What is CCTV?
Many people ask “what is a video surveillance system?” and the truth is that they can be the answer to many security problems. CCTV, in its simplest definition, is the transfer of a video signal from a camera to a monitoring device. And this setup can be used virtually anywhere. Most important to note is the fact that the video signal is private. It is not transmitted publicly and is only available to authorised viewers. The cameras involved can be positioned in almost any location which requires monitoring, e.g. entrances, gardens, car parks, and warehouses. Traditionally, these feeds were recorded to videotapes, but advances in digital technology mean that they can now be saved to hard drives.
What Types of CCTV Are There?
There is a wide range of CCTV cameras available that can suit many different problems. Dome cameras, day/night cameras, C-mount cameras, and bullet cameras are all perfect for specific situations. But all of these cameras work on similar systems, so let’s take a look at these:
- Wired Systems: This type of CCTV setup is most commonly found in larger premises and, as the name suggests, they rely on wires. Running off of a mains power supply, a wired CCTV system connects a camera directly to a recorder. This recorder is then connected to a router which can transmit the signal to wherever it’s required; the signals can be transmitted both internally and externally.
- Wireless Systems: These systems are perfect for both homes and small businesses; the defining feature of this form of CCTV is that there are no wires involved. Wireless cameras transmit their video signal over radio bands to receiver devices that contain hard drives or can upload directly to the cloud. Monitors connected to the receiver are also capable of displaying live feeds.
- IP Cameras: An internet protocol (IP) camera is similar in its design to a standard webcam – it receives and transmits video data over a network and/or the internet. However, an IP camera differs to a webcam as it is a standalone device with a unique IP address. These cameras can be used on both wired and wireless networks to facilitate the transfer, storage, and monitoring of the feed.
Installing CCTV Video Surveillance and Intruder Alarms
The CCTV options available means that there is a solution for every scenario. The result is a home/workplace which is safer and more secure. More importantly, it will deliver invaluable peace of mind to those it is watching over. To maximise your security, you can couple your CCTV system with an intruder alarm. Together, it’s a combination that acts as a major crime deterrent. But remember: it’s crucial that all Security Cabling is installed professionally by experts who know what they are doing.
