Choosing A CCTV System And Installer

What is CCTV?

CCTV stands for Closed Circuit Television and is designed for a limited number of viewers (in a controlled manner) as opposed to broadcast TV which is designed for mass viewing.

It differs from broadcast TV because all the components are linked together (generally by cables) to create a `closed? loop.

CCTV is often used in areas where there is an increased need for security, such as banks, casinos, airports, motorways and increasingly in public areas such as train stations and central business districts in most cities.

Initially developed as a means of increasing security in banks and other high risk businesses, CCTV is increasingly finding its way into small business and homes due to its easy of installation and operation and the continued reduction in pricing thanks to many domestic style products introduced in recent years.

It should be noted that CCTV is not exclusively the domain of security surveillance, but is regularly used in manufacturing process monitoring for QA purposes, for inspecting pipes, chimneys or even the underside of a ships hull.

For our purposes we will be discussing CCTV in its most common form, which is as a security surveillance system.

CCTV System Introduction

From a single camera and monitor to complex video surveillance systems with hundreds of cameras, multiple operators, and digital recorders, closed circuit television (CCTV) systems can provide security for a wide range of businesses.

A good CCTV system can make your business safer, more efficient, and less prone to theft and accidents. Specifically, CCTV can provide many benefits:

- Reduce shrinkage by catching shoplifters
- deter potential thieves
- monitor cash registers
- record evidence to prevent bogus accident claims
- identify visitors and employees
- monitor hazardous work areas
- increase security in and around business premises and parking lots
- meet insurance requirements

The most basic CCTV setup would be a single camera connected directly to a monitor and a recorder to store the video. While a setup like this could help security in some cases, it is unlikely to be enough for most businesses. Most situations call for multiple cameras.

Evaluating Your CCTV Needs

Before starting to compare systems or choose potential vendors, sit down and consider your CCTV needs carefully.

First, you should decide what the purpose of the CCTV system is. Is it primarily to act as a deterrent of potential crimes or to actually catch and prosecute perpetrators? Both can be important, but your priority will influence your purchasing decisions. If you are more interested in deterring certain activities, large, visible cameras are your best bet. Trying to catch criminals on video without them being aware of it requires discrete or hidden cameras. Hidden cameras in many countries can be illegal or may only be used by court order ? so check with your CCTV professional before installation.

Next, consider what you want to monitor. General comings and goings? Vehicles? Do you want to see faces, merchandise, crowds? Once you decide what you want to see, choosing components will become easier.

Then, decide how the images will be used. Do you want to use them for your own review or will your require that they are able to be printed for facial identification or even for admission in a court of law. This will have a big impact on the method you use to record the images and the quality of the cameras, lenses and recorder you will require.

Also consider how your system will be monitored. Will you simply record at all times, and only review the video when a problem occurs? Or will you have a dedicated employee watching for events? Do you want a monitor showing images in public areas?

Three Things To Consider

1. Avoid dummy cameras. While they may deter some problems, they also can create a legal liability by creating an expectation of safety when none exists, plus staff soon learn which ones are active and which ones aren?t.

2. Put up signs. Highly visible signage that lets customers and employees know that they are being filmed can greatly increase the deterrent effect. This is actually a legal requirement in many countries.

3. Do not record audio. Most CCTV systems do not include audio monitoring for the simple reason that it is generally illegal. People in public places can be videotaped without their consent, but their voices cannot.

Choosing a CCTV Installer

Once you know the basic requirements of what you want to see and how you want to use your CCTV system, it is time to call a CCTV installer to get a professional view and price up the supply and installation.

A professional installer will be able to tell you how to best achieve the results of the system you will be installing. That will include the positioning of cameras, the selection of equipment to meet your requirements and budget.

It is important that a potential installer for your job provides references of customers, they have current correct licensing (if applicable for your area) and I always recommend getting a breakdown of the equipment component versus the labour component of a quote.

Don?t just go for the cheapest option unless you are purely using the system as a deterrent. You should evaluate the capability of the installer, the warranty offered on the equipment, the warranty offered on the installation (ie cables), what level of training do they provide and what level of after sales technical support do they offer.

If you have opted to go with a modern digital CCTV installation, unless you are completely familiar with the system, you will require technical support, especially when that first time comes that you need to export video onto a CD or DVD to give to the police. At that time, how sure are you that the person/company that installed the system will be able to provide you with the required assistance.

As a final note on potential installers ? never ever choose an installer that doesn?t do a full inspection of the site in which the installation will take place. If they haven?t seen the site they cannot know of any potential issues that may cause them to need to adjust the price (always up) or take shortcuts that will affect your systems performance.

Once your system has been installed, make sure you and any other staff that may use the system make the time available to be trained. Don?t skip this point as you have spent good money on a system and you will need to use it at some point.

In future articles I will write about choosing cameras, DVRs, monitors and other equipment that will go to make up your CCTV system.

CCTV Security Cameras

Closed circuit television (CCTV) security cameras are there for video surveillance and live monitoring purposes. These may be single or a collection of surveillance cameras which are directly linked to TVs via cables or wireless means. Although CCTV security cameras are useful tools in areas which need high security such as banks, casinos and airports, they are also used in public places and in homes.

The most common usage of CCTV cameras is not crime prevention, but crime detection and prosecution. Several cases have been solved with the use of these cameras. These cameras automatically transfer captured images on a time-lapse or motion detection basis to a PC or laptop using either a USB cable or a wireless adapter.

Most modern CCTV security cameras are simple, light-weight and inexpensive enough to be used in home security systems. There are new and advanced CCTV mega-pixel cameras available which can take 1600 x 1200 pixel resolution images of the camera scene either on a time lapse or motion detection basis. These cameras also use a variety of techniques such as Tilt-Zoom, Low Light, Infrared No-Light and License Plate technologies.

The price of CCTV security cameras depends on many things such as size, type, display, resolution, zoom and wireless/wired models. The common forms of CCTV security cameras are dome, bullet, and standard c-mount cameras. There are B/W and color cameras, and cameras with or without audio. The price starts from $30 for B/W mini hidden cameras without audio and $40 for those with audio. Color cameras without audio are available from $60 and those with audio are available from $70 upwards. Wireless cameras are usually 10 to 20 dollars higher than wired ones. Most decent surveillance cameras are available in the price range of $100 - $350.

CCTV: You Are Being Watched, No Matter Where You Are

Closed circuit TV, CCTV, doesn?t require an introduction at all. The purpose of installing wired or wireless CCTV is fundamentally the one of surveillance and vigilance. These are bigger in size than the wearable spy cameras or hidden cameras and so leave that for the detectives for the moment. (Also what we are not considering now is the Chinese TV channel: CCTV.)

It is thanks to IRA, the Irish Republican Army, for having paved the way for developing the concept of CCTV, albeit in a tragic way. The Royal British Army, in response to the IRA bombings has experimented using CCTV for years, including outdoors, since 1970s through to 1990s. Although exact numbers can not known, an estimate tells us that there are much more than 400,000 surveillance cameras on London streets alone.

Is It Just Military Surveillance With CCTV?

CCTV is extensively being used in security system of industries, banks, super markets homes and all such places which are perceived as strategically and financially important. Commercial establishments using CCTV have increased manifolds in UK although it is not so common in US as it is perceived as a privacy threat. New York City has about 4000 CCTV installations and most of which are in shopping malls and other public places such as Liberty Statue, Lincoln Express, British Parliament, and places of strategic importance. Traffic monitoring and prosecution & crime detection have leapfrogged with the advent of CCTV.

After All, Just What Is This CCTV

Well, CCTV is a closed network of small surveillance TV cameras which telecast and/or record anything in their field of view. CCTV networks are usually wired together and finally connected to one or more monitors. There will be more monitors depending on the importance of surveillance the cost factors. If you have lesser monitors than the number of cameras, they can be switched in a sequence onto monitor/s. CCTV cameras have capabilities to either record hours of footage they filmed or telecast in a short range at a particularly dedicated frequency which can?t be intercepted by normal TVs.

After the tragic bombings in London Metro tubes last July, there has been an increased public demand for using DVR (digital video recording) cameras rather than traditional cameras with tapes. If you wonder how this would have helped the cause, take it here. Tapes were removed in the fortnight following the bombings for study, and follow-up attacks could not be recorded as a result.

Thinking of CCTV installation at your office? Take professional help and consult police if necessary. Some cameras can be hampered with or can be intercepted with cheap receivers. A complete installation won?t cost more than $4000, which is nothing when security is uppermost.

CCTV Cameras - Reduce the Risk of Crime

CCTV Cameras are among the most effective ways to reduce crime in your business or home, and there are a number of places to purchase CCTV equipment, even if you?re on a budget. Here are some things to look for when you?re shopping for CCTV cameras that will help you save time and money, as well as help you to better to protect your property. First of all, you need to choose a CCTV camera that has both a wide range and a quality lens, so that you can see what?s going on no matter which part of the property you?re on, and you?ll be able to spot any suspicious people or activity right away.

Next, make sure that your CCTV camera is compact and is easily rotated. This way, the camera is not easily seen by intruders or customers, and the ability for the camera to rotate quickly and effectively will give you a total view of who comes in and out of your business or home. The Voltek Wireless CCTV camera is a great choice for this reason, and we also offer a number of great new product to compliment this camera. It?s also a good idea to make sure that the CCTV equipment you purchase works well with the way that your property is set up in terms of how many enclosed walkways there are, whether or not there are open spaces throughout the office space or home, and how many rooms are usually occupied on the property. This will help you to determine how large of a camera you should purchase, and you may also want to purchase wireless CCTV equipment to eliminate the look of cables and plugs across the walls of your property.

Other equipment you?ll want to purchase in addition to the actual CCTV camera include a sign that you can post in front of your door or window on your property, which will let both potential criminals and customers know that the property is under surveillance. You?ll also want to make sure that you have a CCTV monitor that is hooked up to the camera, so that you can make sure that your property is safe, no matter where you are in your home or office. The monitors are available in both color and black and white, so you have the option of purchasing the monitors that are most affordable for you. If you?re just starting your business, or are switching alarm systems or moving into a new home or business building, you may also want to look into purchasing a dummy camera for a short period of time. The dummy cameras look very realistic, and you can use it to give the illusion of security on your property until you install a new CCTV camera. You may also want to look into the audio cameras we have to offer, such as the new Wireless Microcam Audio CCTV camera, so that you can hear what?s going on in your property as well as see it.

The shape of your camera will also play a big part in how well hidden the camera is, and how secure you can keep your home or business. Many times, if a surveillance camera is very obvious or large, criminals will immediately try to destroy the camera before stealing merchandise or money, or otherwise damaging the property. If a CCTV camera is well hidden, it will be difficult for burglars to find the camera, and it is much more likely that you will catch the trespassing on tape accurately. A discreet camera will also make customers or others in your home feel safer. So, small cameras, dome-shaped cameras, and even submergible cameras are a good idea if you want to add a little extra security to your home or business.

Common CCTV DVR DIY Mistakes

This article will attempt to reveal some of the more common mistakes to avoid when creating your own CCTV DVR.

1. Budget:
   

   Many DIY'ers simply do not budget enough money for projects like this. When looking at cameras, look at the specs. A $200 security camera and a $50 security camera are going to be very different in terms of image quality and light response. Also look at CCTV DVR features. Places like Costco offer surveillance systems for under $500 but those surveillance systems don't have anywhere near the features of professional grade systems like Video Insight. Those systems can even be missing basic features like video motion detection. You may want to look for surveillance packages that combine everything you need to put a system together, including the CCTV DVR, security cameras, security camera lens's, mounts, power supplies, and cable. Packages like that can start at about $2000 and go up to $10,000 depending on the number of security cameras needed.

2. Surveillance Camera Placement:
   

   Surveillance camera placement is one of the most important factors in an effective surveillance camera system. Ask yourself the questions professionals do: How is the light coming in? How will this change at night? What am I trying to see? How do people move through the area? What kind of blind spots will there be? What kind of surveillance camera lens do I need to use? Do I need to use multiple surveillance cameras to cover this area? Would a side view be better for this then a straight on view?

3. Selecting the right security cameras:
   

   When looking at security cameras, understand what you are trying to do. Are you looking for license plate recognition? If so, then you need to select a camera lens that will allow the plate to be at least 1/3 of the image. This means that a surveillance camera with a wider field of view can not do license plate recognition. The same goes for facial recognition. If you are trying to cover a parking lot with a narrow entrance, you will have to use two surveillance cameras. Very wide entrances can make this very, very hard.

4. Selecting the right camera lens:
   

   Selecting the right camera lens is pretty easy. Note where you are going to place the camera and select the point where you want the best picture. Measure the distance from there to the camera. That is your focal distance. Then measure the width of the picture you want to see. Once you have these numbers you can feed them into a CCTV lens calculator. Looking at the F-stop will give an idea of how well that lens will work at night.

5. Infrared or No?:
   

   Infrared cameras are wonderful for covering areas of complete darkness. But many of the all-in-one camera/emitter units are fairly limited in range. This chart can help with deciding if you need to go the infrared route or not.

   • Direct sunlight: 100,000 - 130,000 lux
   • Full daylight, indirect sunlight: 10,000 - 20,000 lux
   • Overcast day: 1,000 lux
   • Indoor office: 200 - 400 lux
   • Very dark day: 100 lux
   • Twilight: 10 lux
   • Deep twilight: 1 lux
   • Full moon: 0.1 lux
   • Quarter moon: 0.01 lux
   • Moonless clear night sky: 0.001 lux
   • Moonless overcast night sky: 0.0001 lux

6. Focusing the video camera:
   

   This is a simple and easy trick to help with focusing the video cameras. Use a BNC to RCA plug and a small television set to focus the video camera. The ideal time to focus the video cameras is in twilight because it will give the best compromise between the light and dark settings of the auto-iris lens.

7. Cable types:
   

   There are a few types of cable called RG-59. Copper vs. Aluminum sheet and 75% braid vs. 95% braid. For CCTV system work, you should always use copper shielding. Aluminum shielding is meant for modulated signals like cable and allows too much interference for CCTV systems. 75% braid and 95% braid measure how tightly and how much copper is used in the copper sheathing. 95% copper braided cable is more expensive but worth the extra expense. It is much more effective at preventing interference, and much more forgiving of mistakes. We only sell 95% braid copper shielded RG-59

8. Cable runs and Ground loops:
   

   Coax cable should be kept at least 12" away from any power lines and power conduits. The AC power creates a field of interference that will appear like snow on the screen. This can create havoc with motion detection. Ground loops can be caused by securing cameras to metal structures that have a different electrical ground then the power supply. This will cause bands to move through the screen. Solving this is a matter of eliminating contact between the cameras and the source of the ground.

9. Sony Cameras:
   

   Sony has a line of CCTV surveillance cameras, but all of them are clearly marked Sony. You will see a lot of sites offer "Sony" cameras when they don't say Sony on them. The reason for this is that Sony makes about 75% of the worlds CCD chips, which are used in everything from Camcorders to digital cameras to CCTV security cameras. The CCD is an important part of the security camera and has an impact on the resolution, but the electronics behind the CCD also have a big role in how good your image is.

10. What determines how good my image is?:
    

    How good your image is depends on quite a few things. It depends on how good your lens is, how well it is focused, what the resolution is, and how good the S/N (Signal to noise) ratio is. When looking at a camera, you generally want both the highest resolution and the highest S/N ratio you can find. The Signal to noise ratio is a Logarithmic scale so the difference between 46 dB and 48 dB is a rather large difference. If forced to select between a camera with a slightly lower resolution and a high S/N ratio or a camera with a higher resolution and lower S/N ratio, try to select the one with the better S/N ratio if you are doing longer (500 ft+) cable runs. For shorter runs going with the higher resolution is okay.

11. How many FPS do I need?:
    

    Many manufacturers and distributors will try to push their highest frame rate DVR's and Cards on you because those items have the best profit margins. But high frame rates may not be in your best interests from both a storage and budgetary perspective. For most applications 3 to 7 fps is fine. If your goal is to identify theft or vandals then 3 fps is almost always enough. The only time one should consider more then 15 fps is if you have to watch for sleight-of-hand like watching a register. The reason to avoid higher frame rates is that they take up more drive space, reducing the total storage time of the system. It can also divert budget away from selecting the right cameras which is far more important and more likely to generate usable evidence then a higher frame rate.

12. Audio Recording:
    

    Don't do it! In many states it is illegal, period. It does not matter if it is your home or other private property. The law only cares about if the people being recorded are aware that they are being recorded. A number of people tend to think "Well, I'll put it in anyway, it's not like someone is going to report me." The problem with that line of logic is that if you ever submit video as evidence to a court and you are in violation of your state's laws or federal laws, then you have just given proof to the courts that you also committed a crime. The best possible outcome is that the court throws out the recording and you don't go to jail. But if you can't use your recordings to help convict a person that has wronged you then what good was the money you spent?

13. CSI:
    

    As a general rule of thumb, anything you've seen done on television or in the Movies with video enhancement is simply not possible in the real world. You can't make data appear where there is none. There is no magic trick to make that work.
