Closed Circuit Television (CCTV) security cameras has become the new standard of security and surveillance. CCTV security cameras were first used in 1942 to observe V2 rockets launching. CCTV security cameras have also been used to monitor unsafe industrial processes, such as manufacturing nuclear fuel.

In the 1970s, the United Kingdom began using CCTV security cameras due to bombings by the IRA. Today, many public areas in the UK are under surveillance. The British government claims that its CCTV security camera network has resulted in a significant reduction in crime, but this claim is unproven.

Some criminals have found ways to evade CCTV security cameras. Painting the lens, flashing laser pointers or jamming the wireless signal is common. Some criminals simply shoot out the cameras, although this can be countered by placing the CCTV security cameras in bullet-resistant housing.

Opponents of CCTV security cameras have argued that it results in the loss of privacy and civil liberties. With the prevalence of CCTV security cameras in the United Kingdom, as well as Chicago and New York, it has been criticized as a method of controlling the general populace and not as a deterrent to crime. Questions have also been raised about who may obtain access to CCTV security cameras’ recordings, and concerns about an overall lack of anonymity have been raised.

CCTV security cameras are beginning to transition to digital. With high shutter speeds, memory capacity and pixel resolution, photos can be taken either when alerted by a motion detector or on a continuous basis. Boasting an easy setup and storage of images on the computer, it is proving quite popular.

A home or business surveillance system is only effective if it is a complete working system.  Take a component out and you will have crippled equipment that could no longer protect you and deter crime effectively.  Here are some of the most important camera and surveillance accessories you should have:

Power supplies
Power supplies connect equipment such as cameras or CCTVs and digital recorders to a source of electricity.  Although many of the models being sold these days run on DC or battery power, there are some home and business owners who prefer to use electricity to ensure that their surveillance equipment ran continuously.  

Some power supplies are also designed to handle both AC and DC outputs, particularly in camera and surveillance equipment that can make use of both alternately.

Transmitters & receivers
Transmitters and receivers are essential components of any surveillance equipment.  A transmitter send signals over a pre-determined frequency to a receiver.  These accessories often come as a pair or part of a kit.  The effective range of transmission varies, depending on the model or make.  

For surveillance use, most transmitters are small enough to be concealed or disguised using everyday items, although that doesn’t automatically impair their ability to work with a compatible receiver.

Active-passive baluns
Active-passive baluns help ensure compatibility between systems, something that is critical in camera and surveillance equipment.  To manage video images, many of the latest models now use internal baluns, even though almost any camera used for surveillance can be utilized with external baluns.  The latest balun transmission systems can even handle HDTV signals.  With active or passive baluns, users of camera and surveillance systems can eliminate the need for additional cables to connect one equipment to another.

Amplified microphone
A microphone is an important accessory for a camera and surveillance system if audio is required.  Amplified microphones are more efficient in picking up sound waves within a room or area compared to ordinary microphones.  Some models require an independent power source while others can tap power from another device such as a camera, for example.

Although amplified microphones have become a part of most surveillance systems, it’s still good to note that there are laws that protect people against illegal ‘bugging’.  If you’re purchasing an amplified microphone, be sure to check your local state laws regarding its proper use.  

Camera brackets
In most surveillance systems, cameras are frequently mounted so they can monitor a wider area.  To ensure the equipment’s stability, there are camera brackets that are specifically designed to hold them up.  Camera brackets are usually made with metal, wood or plastic.  Many have interchangeable parts, so they can be used in different combinations.  They are flexible enough to be mounted onto a ceiling or a wall.  Camera brackets have limited strength, so it’s best to check the maximum weight of surveillance equipment they can carry.

When one thinks of one’s own Home Security one may be hard put to establish the best solution to select. The least one should do before deciding is to take a hard look at the available proposals and explore them attentively from every side.

Two are the main types of provisions one can consider to set up: either an independent surveillance system with alarms and automatic event reporting, or a subscription to a surveillance service as offered by security providers.

We would like to mention here briefly the advantages and limitations of the second of these two above options, the one offering such integrated services, and to point out why in some cases it may be just the right solution.

Among the important advantages that one should consider are the following:
Your system will be set up by Professionals
They will be fully accountable for maintenance and continuous operation
They may charge for service, not for hardware
Integration means that proper sensors for any type of other hazards can be included
Continuous monitoring  occurs at a central station responsible for taking immediate action whenever required
Certain providers may dispose of their own rescue crews to dispatch
You can be awarded a document capable of gaining you a substantial rebate from your insurance company

Some of the limitation of most services may be as follows:
Only homeowners, not tenants, may be eligible for service
An event will trigger a call to official security services (police, firefighters etc.)
There is no control on the effectiveness of this action, only follow up
The customer may be bound to a minimum contract duration (three years)
The recurring expense may be significant

If one is tempted to rely on security providers for assuring adequate home surveillance and protection, it would be advisable to obtain a few offers from different firms and to compare them. If you collect the names of other customers you will be able to check if they are indeed satisfied with the service they get.

By selecting the best security service provider one is fully relieved from the fears of technical hurdles. One is not relieved however from the responsibility of having got indeed the most desirable of solutions.

Increasingly video-based surveillance and security systems are being widely adopted by both corporations and consumers primarily due to increasing need for surveillance in these turbulent times but also due to affordability of security systems, ease with which surveillance systems can be installed and value-add features such remote monitoring that address special surveillance needs. As a result video-based surveillance systems are increasingly appearing in public areas such as airport lounges, shopping centres, retail stores, colleges, universities, manufacturing facilities and corporate offices. These video surveillance systems can be CCTV or IP based. Consider the benefits that a video surveillance system provides and the broad adoption by the market is quite understandable. A surveillance and security system:

Helps deter employee theft and shoplifting theft, Helps monitor & document performance in manufacturing or other facilities resulting in potential reduction in maintenance cost and/or employee productivity improvement, May help reduce insurance cost and fraudulent liability claims, and Can continuously document events so your entire business has greater protection.

Reasons for Large LCD Monitor Adoption: Within these surveillance systems packages, large LCDs monitors (>42”) are becoming the industry norm. The reasons being:

Size: Large screens allow for continuous and simultaneous monitoring of multiple camera video feeds on one screen with clarity. Smaller screens require that the images from the video feeds to rotate creating holes in the monitoring data. 24×7 Operations: Professional LCD monitors are meant for 24×7 “round the clock” operations with long life. CRT televisions or Plasma television each have their issues with round the clock operations such as static or flicker for CRT televisions. Also, the life of a CRT or Plasma TV is much shorter when operated in 24×7 operation mode as compared to an LCD monitor. CRT and Plasma televisions are built to be on for a few hours per day. Picture Quality: Most large LCDs are high definition. High definition LCDs provide better picture resolution, better contrast ratio, high brightness, high colour reproduction and fast response time resulting in better picture clarity which is especially helpful when the camera is being zoomed in or multiple images are viewed simultaneously. High Definition LCD TV allows you to view minute details like number plates of a speeding car, face of a person etc. Further, the non glare feature of LCDs allows for easy viewing in ambient light or where there is background light being reflected on the screen. It is harder to reduce glare in CRT or plasma televisions. Most new LCDs have 176° viewing angle, making it easy for viewing. Check the viewing specifications to make sure meets your quality requirements. Robustness: LCDs generate less heat than a CRT or Plasma television. The fan-less design for most large LCD monitors results in a closed box display with less noise. The fan-less design and the closed box display also results in less dust entering the system and provides for a more robust architecture. Space: LCD monitors are flat panel displays requiring less space than normal CRT TVs. They can be wall mounted. The LCD monitor can be encapsulated in a fire retardant frame to protect the display Better Video and Data Merger: Increasingly programs are being utilized to identify theft or issues in real time and data is being merged onto the video stream in real time. LCDs provide for better merging and viewing of data with video. Remote Monitoring and Operation of Large LCD Screens: Alarms can be set if an LCD screen is switched off. Power and other controls can be monitored remotely. For example, an energy saving feature can be activated so that when there is no signal, a power save mode is activated to reduce the brightness of the LCD backlight. Value-add Features: Value-add features such as touch screen zoom-in /zoom-out and image swap or other functions such as internet access can be easily found or added onto LCD monitors.

Purchase Consideration When Buying a Large LCD Monitor: Besides price there are a few items to consider when purchasing an LCD monitor.

Match LCD Monitor to Camera Capabilities: If you buy a monitor with lower resolution than the cameras installed then the camera capabilities will not come through. Ideally the monitor should be equal or better resolution than the camera. Also, if the cameras are black and white, then a black and white monitor can be used. Input /Output Connectors on the Monitor: With the increasing use of PC and digital video devices, it is important to have both analog VGA and digital DVI input terminals to the monitor. Also, be sure that the monitor has BNC connectors for direct connection from a video feed to the display. BNC connectors support video looping, which provides output (loops back) to a centralized recording facility (DVR) or to other displays in a daisy-chain pattern. When scrolling through different images, this allows for seamless integration between pictures . Picture Quality Features: Consider the resolution, contrast ratio, brightness, colour reproduction and response time to meet your surveillance need. Value-add Features: Consider the value-adds that address your need. Such as, do you need remote monitoring, touch screen capability, or internet access?

Make the knowledgeable decision and your surveillance system can address your needs for many years.

A closed circuit television (CCTV) system is an integral component of the security measures adopted by businesses. Business premises as well as business processes need to be monitored on a regular basis to ensure safety. The need and extent of safety required helps decide the investment required for the CCTV system; for example, deciding whether procuring a single camera and monitor will suffice or a complex video surveillance system with multiple cameras, multiple operators and digital recorders is required.

The investment in a simple or hi-tech system is justified on the basis of the following benefits of a CCTV system that:

Helps surveillance of areas that require security round the clock
Helps observe and control traffic
Prevents theft/ shoplifting, robbery and other crimes
Helps identify and initiate legal procedures against offenders with visual evidence from the CCTV footage
Raise alarms on approaching dangers or avoidable circumstances
Besides the many advantages listed above, one of the key reasons that contributes to the popularity of a CCTV surveillance system is the advancements in technology. CCTV systems have come a long way from being cumbersome, expensive and complex systems requiring expert help to simple, easy-to-use systems that are easy to configure, easy to maintain and reasonably priced. Moreover, the new range of surveillance systems offer more options, clarity and versatility than before.

Equally importantly, the benefits of installing a CCTV are not limited to business enterprises but also private property owners and households that can feel safe and secure with an efficient surveillance system.
