CCTV Installation

CCTV is massively powerful tool for not just deterring crime, but also capturing the people responsible should you be unfortunate enough to be a victim of crime.

Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.

It differs from normal household television in that the signal is not openly transmitted, though it may employ point to point wireless links.

Although almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require monitoring such as bars, banks, casinos, schools, hotels, airports, hospitals, restaurants, military installations, convenience stores and other areas where security is a requirement.

In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.

A more advanced form of CCTV, utilizing digital video recorders (DVR/NVR), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts).

More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.

There are about 350 million surveillance cameras worldwide as of 2016. About 65% of these cameras are installed in Asia.

CCTV use is widespread in the UK.  According to newspaper reports (Telegraph, Guardian) there is a surveillance camera for every 11 people.

Cameras are widely and overtly deployed every day, they are sited within both over-ground and underground train carriages, above supermarket checkout points almost any place you can think of.

Whatever our own personal views, the irrefutable benefit of CCTV systems are its crime prevention and detection capabilities.

Like it or not, monitored camera surveillance is essential in many businesses, not just for the safety of staff and customers, but also for the security of the premises, property & cash.

CCTV PROPERTIES WE COVER

DOMESTIC – From a small 2 camera system

COMMERCIAL –  To a 400x camera system

FARMS –  To pan and tilt cameras able to help farmers stay on top of the calving season from the comfort of their home

System Technologies

When investing in a CCTV solution you are presented with an almost overwhelming number of choices. However, the real consideration will be to make sure the correct camera is used, we use the latest IP CCTV equipment which is full HD from 4 megapixel HD (2560 x 1440 tvl) to 12 megapixel ULTRA HD (3840 x 2160 tvl)

These cameras are so clear that we are only now using tvs (4k) that will produce the picture quality they record

The camera have LEDs which will come on when the light level drops too low for a clour image and produce the white light needed for a superb black and white image in total darkness, there are also cameras that will stay in full colour even at night so give us a call to discuss your requirements.

Recording & Monitoring

CCTV recording cameras are linked to recording devices (DVRs / NVRs) either locally or onto an internet network.

Recorded images can then be monitored efficiently and safely from a remote point, password login can give access even to hand-held devices such as tablets or mobile phones connected to the internet.

Technology has evolved a long way forward since its first use by Siemens back in the 1940s.

Analogue HD

We are currently upgrading existing CCTV systems which are cabled with coaxial cable (traditional analogue wiring) with HD cameras as a good upgrade solution which removes the added cost or re-cabling.

Our CCTV supplier has a large range of high quality HD-CVI cameras, recorders and accessories available. HD-CVI  unites the high quality images of IP with the point to point configuration of analogue systems.

This technology is a great way to upgrade an existing analogue system to digital. (*Subject to cable quality)

  • Unlike IP, HD-CVI operates over the familiar closed circuit system which eliminates any security threats that could compromise the system and also the need for IT expertise to
    support and manage it.

 Similar to your HD TV at home HD-CVI can offer impeccable picture quality for your CCTV system giving 720p  TO 4K resolution in real time (25fps). This broadcast quality does not have bandwidth issues since it is connected directly to the DVR from point-to-point.

  • HD-CVI Digital Video Recorders generally allow remote access via a web browser or mobile phone device to enable the system to be monitored and controlled remotely if required.

IP Camera Overview

“IP” stands for Internet Protocol which is the low-level programming language used to transmit data between computers in your home and the Internet.

This means that an IP camera is like a little computer that you connect to, to access your video and as such you do not require a direct connection to a PC to operate meaning they can be placed anywhere within a network and accessed remotely at any time.

Consequently they do not require a DVR; instead they operate with a NVR (network video recorder), which in most cases is just software that runs on a computer or server as it doesn’t need to convert analogue video to digital.

The video footage can then be stored on new or existing network RAID (redundant array of independent disks) drives as directed by the NVR software.

In contrast to an Analogue camera, an IP camera excels in capturing high definition, megapixel images as captured data is digitized directly from the sensor, and because of their increased computing power they can perform more advanced functions such as detecting motion to trigger recording or tampering and act on it by emailing, uploading or recording images or video to an internal storage card external storage device

Expansion & Storage

Analogue: DVR costs are fairly simple to understand. A DVR is a single unit, and has a single cost. However, they have a fixed number of inputs that cannot be expanded upon.

IP: NVR software is typically licensed on a per camera basis and must be installed on a networked computer. The storage requirements for megapixel cameras are significant, and may require additional network points.

CCTV MAINTENANCE

As the term implies, CCTV preventative maintenance involves regularly testing the functionality of CCTV surveillance equipment to reduce the probability of a malfunction or failure.

Maintaining systems regularly will ensure CCTV systems are working to their optimum performance and that images recorded and stored are fit for purpose, and are of evidence quality and could be used as admissible evidence for purposes of investigation or for use in courts of law.

Preventative maintenance is an essential part of ensuring continuous surveillance and helps to deter break-ins, theft and the overall security of the area(s) being monitored.

To avoid any lapses in surveillance monitoring, CCTV system maintenance is usually carried out whilst all devices are still in operation.

This regular inspection should be planned as part of the overall security system maintenance checklist requirements of the business or household.

It is also a good idea to organise the inspection date so that any spare parts that may be needed are readily available.

In summary, preventative maintenance increases confidence in the entire security system, and is often a written requirement as well as a condition of commercial building insurance.

The owners or operators of a CCTV system should normally be able to keep CCTV cameras free of everyday dust and obstructions, but any technical scheduled maintenance must be carried out by trained service engineers.

Watson Alarms offer a totally flexible CCTV maintenance solution which ensures your CCTV system is kept in optimum condition.

Our Standard Service Care Package is based upon a 4 camera system and includes 2 service visits per year (one in the spring & one in the autumn), all cameras will be cleaned and adjusted as required.

Where additional cameras are installed these will be added to the service agreement at additional cost.

The maintenance contract is inclusive of standard emergency call out Monday to Friday 9.00 – 17.30 (Additional Options Available).

During the service visit our engineers will:

  • Verify that the number and type of cameras installed, as well as lenses, corresponds with records held by the Client.
  • Act on any previous notifications or issues reported by the business.
  • The camera checking component of the security system maintenance checklist should include comprehensive cleaning of the lenses and housings.
  • Once the camera is properly cleaned, the engineer is required to monitor all automated and remote control functions and that all camera movement, as well as the area of the premises they view, are not obstructed.

Once the camera is shown to be working as it should, the next step is to check the audio and recording equipment.

  • If there are any external cameras, ensure that any plants, trees or shrubbery do not impede the view, recording or any other function of the CCTV camera.

Most insurance companies will insist on this as a condition of the insurance, and the service will require the growth to be regularly cut back.

  • Check that all cables are properly mounted, or supported by the correct conduit, and that the insulating plastic is showing no sign of wear and tear.
  • Check that all indicator lights and pre-sets are functioning correctly.
  • Verify that all warning labels and notifications are present and clearly visible. This also applies to a full connection check of all components in the CCTV circuits.
  • Check that all fixtures and fittings that ensure that the CCTV itself is properly supported are in place. This examination should include looking for signs of physical damage and any form of chemical corrosion. Any damage should be repaired as soon as possible. Many business owners check that such repair work is possible within the terms of their maintenance contract.

Where the CCTV cameras are linked to the security and fire alarm system as such that the CCTV preventative checklist needs to ensure that the correct alarms are triggered.

Related to this test is ensuring that the ambient lighting does not affect the view from the cameras in the device.

The engineer is also required to check any log books or computer held data pertaining to the CCTV system and advise on any necessary updates relating to such data.
