CHOOSING A CCTV SYSTEM
A CCTV (closed circuit television) System is the use of video cameras to send signals to a particular place on a number of monitored displays. It allows for monitoring of the activity and visitors on your premises.
There are a number of different systems available, specific to your particular requirements for CCTV, whether that be for building monitoring or identification in the event of a crime.
CCTV systems can be used as both a surveillance tool and as a method of identifying and prosecuting thieves.
Where CCTV is used to monitor people activity on-site, it should be positioned at a high level to make sure the best coverage is captured. If in use to detect any criminal activity, it should be located at eye level so faces may be viewed more clearly.
It could also be that the police or your insurer has advised that you need to have a system in place or that your premises is a higher risk environment.
A system of this kind can also be used for other uses such as protection for lone workers, monitoring customers visiting a shop or building, for time management purposes to ensure staff are on site at the correct time and for health and safety purposes.
We can help you decide whether or not a CCTV is the best option for you and also help you to assess which areas you wish to have covered. This will then identify exactly where cameras should be sited in order to provide the best surveillance coverage. It is beneficial to have your site surveyed professionally by one of our CCTV Systems experts. We will be happy to visit you Free of Charge. Our expert will consider your requirements and produce a plan of exactly where you should install CCTV to fit your specifications.
TYPES OF CAMERAS
STATIC – Static cameras are fixed with the camera viewing one particular dedicated scene. Typical static applications are specific concentrated areas that require static coverage without the need to cover a large area, minimising the required budget for the equipment. Static CCTV cameras focus on risk areas which is always more effective when the correct lens configuration is gained to pin point specific detail, i.e. facial recognition, retail transactions etc.
DOME – Named for its dome shape, it is the most common security camera you see in businesses and stores. Due to its shape, it’s difficult to tell exactly where the camera is aiming unless you see it up close. Dome cameras are generally used inside buildings, although the domes can be used outside as well and can be mounted on ceilings or walls. Supplied as Static or PTZ versions.
PTZ – PTZ stands for and signifies the camera’s ability to Pan, Tilt and Zoom. This means that the camera can be controlled from a remote location, such as a control room, a keyboard/joystick in an office or in a security watch room. Typical PTZ applications are extensive areas that would require such a large number of static CCTV cameras that would exceed the budget for equipment and labour. PTZ cameras provide a good bridge between requirement and cost. Additionally when security staff are employed or the camera includes the PTZ Object Tracing function, objects can be followed at a high optical zoom level and produce high quality crime scene evidence.
BULLET – The name for the bullet camera comes from its resemblance to a rifle bullet – generally long and tapered like a cylinder. Bullet cameras contain the same electronic components as C-Mount cameras but have been modified to fit in bullet weatherproof casing.
C-MOUNT – The advantage of a C-Mount camera is that the lens can be changed. If you need to see further than 35 or 40ft then you’ll need a C-Mount camera with a special lens. C-Mount lenses are available from 4mm to 50mm. A 4mm lens provides facial detail and a 70 degree angle of view focused up to about 35ft. An example of where you might use a fixed 4mm lens is in a small office, or at home to focus on your driveway.
C-Mount cameras are able to be mounted within a rugged housing that is heated for cold environments with wipers attached to ensure a clear view.
COVERT/SPY CAMERA – A covert/spy camera system allows video images to be captured in secret. These cameras can be disguised as everyday standard items such as lamps, thermostats, clocks, smoke detectors and many more. These cameras are also able to be supplied analogue or IP and can offer Mega Pixel resolutions
VANDAL RESISTANT – Vandal resistant cameras and housing offer resistance to vandalism and are designed to keep working whilst under, and after an attack.
WIRELESS – Wireless cameras offer all the same principles of a standard hardwired system, without the wire. They transit the video/audio signals through a radio band. The camera will still require power (that cannot be wireless) but some models offer a battery pack option making them truly wireless.
CCTV SYSTEM MAINTENANCE
Ongoing maintenance of the system by a competent approved security systems company should be carried out.
All CCTV systems should have a preventative maintenance visit where tests are carried out to ensure the system operates at an optimum level and any failing parts are replaced before they cause a major malfunction. These tests should be carried out annually.
DETECTION AND MONITORING
When utilising a monitored CCTV system, detection is added to the camera locations to enable alarms to be activated and alert to the presence of an intruder. When a detector is activated, alarm recording starts and a CCTV operator can initiate a response or action as required.
If a monitored CCTV has speakers installed upon it, audio enables the operator of the system to engage in conversation with the person who has activated the system via its detection.
