The excellent capabilities of CCTV cameras with WDR (wide dynamic range)

Cameras with wide dynamic range capability are commonly used in surveillance cameras, video systems, and some medical applications. In surveillance, WDR is intended to provide clear images even under backlighting, where the intensity of illumination varies a lot—namely when there are very bright and very dark areas simultaneously in the camera's field of view. WDR allows an imaging system to correct for the intense back light surrounding a subject and thus enhances the ability to distinguish features and shapes on the subject. WDR cameras are usually recommended for situations where light enters a premise from various angles such as a multi-window room. A camera placed on the inside of the room will be able to see through the intense sunlight or artificial light coming in. If an indoor security camera is pointed towards a window or an entrance door, you will see the background washed out during daytime. This is a common occurrence in restaurants and stores with large glass windows.

On our Website www.cctvsuppliersuk.co.uk we supply many types of CCTV cameras with Fantastic low capability. Some of our cameras come with WDR (wide dynamic range) this enables you to gain so much more from CCTV with only adjusting settings.

How CCTV works

Wireless home CCTV systems

Images can be transmitted using analogue or digital technology. Wireless systems can suffer from interference from devices such as routers, cordless phones and microwaves, and can be blocked by heavy masonry or metal objects.

Outdoor home CCTV cameras

If you’re using CCTV cameras outside, make sure they’re weatherproof – an IP (International Protection) rating of 66 is recommended. Wireless cameras are available, but you’ll still have to run a cable to a power source. Position cameras where they can’t be tampered with but can be accessed for maintenance and cleaning.

Indoor home CCTV cameras

Indoor CCTV cameras come in three types: wired, wireless and powerline networked (these plug into your electrical sockets and transmit images to a storage device). Wireless cameras are not recommended inside the home unless the signal can be encrypted, as anyone within range and using a suitable receiver would be able to view the images.

Storing CCTV images

Most home systems use a PC hard drive or standalone digital video recorder (DVR). The main advantage of PC-connected systems is that they often come with software to view the images. Some DVR-based systems have this facility. Make sure that your system allows you to store images in a widely used format, such as Mpeg – otherwise there may be problems if images need to be downloaded and viewed on other systems, such as those used by the police.

Remote access

Some home CCTV systems let you check images over the internet using a PC or smart phone. Other options include email or text notifications when cameras are activated.

Night vision

Monochrome (black and white) CCTV cameras tend to be the most effective in low light, particularly when used with integral infrared illumination – a feature found on some cameras. It’s possible to use CCTV cameras that will film in colour during the day and switch to monochrome when it gets dark.

Home CCTV cameras with motion detection

Some CCTV cameras have a sensor that turns them on when they detect movement. This can be handy if you want to reduce the amount of footage you’re storing.

CCTV footage resolution

High-quality images are needed if CCTV footage is to be used as evidence in court. However, for the best detail a high resolution is required, and this can take up a lot of storage space. The minimum recommended resolution is 352x288 pixels. Also ensure that the date and time used to ‘tag’ images is set accurately.

CCTV and Privacy laws

If you’re thinking of getting a home CCTV system for the outside of your property, you must comply with privacy laws. This means making sure that your cameras aren’t pointed at public space or other people’s houses or gardens. 

It’s a good idea to discuss any CCTV plans with your neighbours first – some people told us that they share a system with their neighbours, which might be one way to cut down on costs.

CCTV is just one line of defence against crime, and works best when combined with other measures, such as door and window locks, keeping trees and foliage cut back, security lights and a burglar alarm. 

The Benefits of installing CCTV Camera Systems.

Obviously, the biggest advantage is the security aspects that both CCTV can bring your company. CCTV will allow you to keep a track on people within your store to ensure that they do not shoplift, and if they do then you have proof that they attempted to do it. This of course will result in a much greater chance of successful prosecution. Alarms will stop people entering your building out of hours. If the alarm is triggered then you will be contacted, as well as the police in order to deal with the situation. If any property was taken during the break in, then the CCTV will be there to get a recording of the people that entered, once again maximising the chances of bringing a successful prosecution, and of course getting your property back. All together this should help you save money in the long run. There has also been a big increase on domestic properties having CCTV installed nowadays as well. It is the best way of protecting your property from opportunist burglaries and vandalism. The Systems act as a deterrent for crime, If people see that these are in place then they will be much less willing to commit crime against that property. In residential premises, if you have a CCTV Camera in place, you will find that you feel much safer in your property, this will give peace of mind to the homeowner.

As you can see, the benefits of CCTV and alarms are far reaching, in this day and age it IS the best way to protect your property, whether you own a residential or commercial premises.

Should we be upgrading to HD-SDI CCTV technology?

Your old analog system has served its purpose and it's time to upgrade. Like your television, surveillance systems have gone digital HD and if you're like most people you will want to take advantage of the high quality video made available to you. With HD-SDI you have the ability to simply swap out your existing analog cameras and digital recorder and install a newer HD quality system quickly. Taking advantage of your existing coax cable and power makes this transition simple and effective. You can enjoy 128 times higher resolution than your standard analog cameras and take advantage of the digital zoom capabilities provided by the megapixel video. It has never been easier to upgrade your existing system. 

CCTV Image quality advice

Your CCTV is only as good as the last picture it took.
Make sure your system is of high enough quality to guarantee that the images you need are good enough to use as evidence.
The Downside of installing budget CCTV Equipment is if the evidence you need is no good then that few ££ you saved can turn out to be a total waste of money and investment.

At CCTV SUPPLIERS UK we guarantee all our cameras to stand up to the quality you need when installing surveillance.

CCTV networks

A common estimate used is that made in 2002 where it was estimated^[10] that the United Kingdom was monitored by over 4.2 million CCTV cameras, some with a facial recognition capacity, with practically all cities and towns under 24-hour surveillance. However, many have strongly condemned the assumptions behind that estimate, noting that it involved the extrapolation of observation from one 1.5 km long street in Putney, London to the entire population of the UK.^[11] In addition, the vast majority of cameras are not operated by the UK Government, but by private companies, especially to monitor the interiors of shops and businesses. According to 2009 Freedom of Information Act requests, the total number of local authority operated CCTV cameras was around 60,000 over the entirety of the UK.^[12]

Currently, in the City of Westminster, microphones are being fitted next to CCTV cameras. Westminster council claims that they are simply part of an initiative against urban noise, and will not "be used to snoop", but comments from a council spokesman appear to imply that they have been deliberately designed to capture an audio stream alongside the video stream, rather than simply reporting noise levels.^[13]

As of Feb 2010, many larger cities in the UK now have CCTV in which if an operator spots anything illegal or troubling, they are able to speak through the cameras via loudspeaker into the street, and some also have microphones to allow them to hear what the public are saying.

Closed Circuit Television

Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used forsurveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.^[1][2]

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 (DVRs), 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-based CCTV cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world including the United Kingdom, where there are reportedly more cameras per person than in any other country in the world.^[3] There and elsewhere, its increasing use has triggered a debate about security versus privacy.
