What is CCTV and what is it used for?
As the name implies, Closed-circuit television (CCTV) is a TV system where the viewing of the signals is restricted to a specific place, or a specific set of monitors.
As a security system, CCTV can act as a valuable deterrent; can provide live monitoring to enable you to take action where required; and can be used for evidential purposes. According to latest crime stats, CCTV surveillance is useful in about 65% of crimes where CCTV footage was available.
Although CCTV is primarily for security purposes, it can also be beneficial for surveillance for health and safety and monitoring business processes.
What does a standard CCTV system consist of?
Whilst there is no ‘one size fits all’ CCTV system, they do have the same basic components:
- Video management & recording system
- Cable and Connectors
- Power Supply
Types of cameras
CCTV cameras have become increasingly sophisticated and there is now a wide choice, depending on purpose, location and budget:
So called because of their shape, these are relatively small and inexpensive, designed for wall or ceiling-mounting, primarily indoors (although some are suited to outdoors use).
These dome shaped cameras cover a wide surveillance area. Best suited for indoor surveillance.
For when you don’t want the camera to be seen. These can be disguised in virtually anything you can think of, including a smoke alarm, fan, clock or even a screwhead.
Whilst most cameras are designed to operate in either daylight or night time, Day/Night cameras can do both, making them ideal for businesses requiring 24-hour surveillance.
High definition cameras provide the very clearest of images for when it’s vital to be able to see extreme detail as it happens, such as in a bank or casino.
All these cameras come in a variety of versions depending on usage, such as internal / external use; day or night use, the latter of which feature infrared lighting; fixed view or pan, tilt and zoom (PTZ) where the camera can be moved around.
Modern CCTV recording
Gone are the problematic days of recording CCTV images to VHS tapes. Nowadays, there are a host of far better options, including a DVR for storing a single feed for days or weeks, to distributed, IP-based video recording solutions that can capture everything that happens throughout your facility for months and stores footage remotely. The STANLEY Security Video Cloud is one such IP based system - a fully managed cloud video surveillance solution, delivering an end-to-end video management system that is simple to deploy and easy to use.
Latest trends in CCTV – ditching the cabling
In the past, CCTV systems required their own cable network, which added to the cost of the system in terms of equipment and installation work, plus it was disruptive. Nowadays, IP based CCTV systems enable all signals to be run through a site’s existing IP network, removing that additional cost and making for a much faster installation.
In addition, many CCTV cameras offer wireless connectivity, using Wi-Fi to transmit signals to the security system, ditching cabling altogether (although power cables are still required).
