Just What Is Surveillance Technology?

The technology of surveillance equipment is continuing to advance at a very rapid pace. As a result surveillance equipment has become almost ubiquitous in retail stores, public schools, gas stations, and airport terminals all across the United States. There is a wide range of surveillance technology that is available on the market. Surveillance equipment ranges from wiretapping phone and internet based equipment to high tech facial feature recognition computer software known as biometrics.

Surveillance equipment makes the world infinitely more manageable for people who need to protect their belongings and protect people and make its far more difficult for people who actually want to commit crime. As more of the high-tech surveillance equipment becomes more and more easily available to the general public and small business owners, more and more people will reap the benefits.

The basic concept that underpins a piece of surveillance-equipment is one of 'you will be seen'. The gist of it is that criminals may well think twice about committing a crime if they think they might be seen, identified and then found later on and be charged with a crime. Although it is unlikely that everything can be caught on surveillance camera at one time, on the occasions when surveillance does pick up activity, it does provide enormous help to security and police in identifying the offenders.

These days the more advanced surveillance equipment operates in the same way in an effort prevent crime from occurring, so it has not veered from its original intent. Indeed many small businesses decide to install dummy cameras that don't actually record anything, indeed don't even turn on, but act more as a preventative measure for potential offenders.

One of the main reasons for the establishment of surveillance equipment is to prevent the theft of merchandise from stores and warehouses. Usually offenders come from outside the company and so the theft can be caught on tape and referred to the police. But on occasion the offender will actually come from within the company and then employee policy needs to be implemented. Upon discovering the internal offender that employee will usually find themselves without a job.

Apart from the examples outlined earlier, shopping malls, parking garages, office buildings, and warehouses and financial institutions all now commonly use video based surveillance equipment in order to protect their wares and to also to limit the costly losses incurred by dishonest employees. Major department stores who have high internal theft rates use these video surveillance systems to actively prosecute thieving employees.

How To Choose A Camera System

There are many reasons to install a camera system. If you own a business, you may want to be able to identify or avoid theft or keep vandalism from your property. Or you may just want to be able to keep an eye on things without actually being there physically. As a homeowner there are a bunch of other reasons to have a camera system. You may be having trouble with a neighbor, trespassers, vandals, or perhaps you have kids and want to be able to keep an eye on them but you can't be there every minute of every day.

Whatever your reason for wanting a camera system if you don't get the right kind of equipment based on your needs, you will just waste your money. So if you are thinking of getting a camera system, you will need to look at your situation in order to get the right system.

Some questions to ask yourself:

1. Is what you want to see indoors or outdoors?

2. How many areas do you want to see at your location?

3. Is there a lot of light available throughout the day and night?

4. Do you want to see a wide area, such as a parking lot, or a specific location, like the front door?

5. Is it important to see the small details or is a general idea good enough?

6. Do you need to see the picture only on sight or is off sight viewing necessary?

7. Do you need record what the camera sees?

8. Do you need to record for a long or short period of time?

Okay, now that you have an idea of what you are trying to view, we can take a closer look at the equipment.

Camera-

First let's look at the camera itself. There a hundreds of cameras to choose from. There are even fake cameras that you can use if you only want to give the illusion of having a system. Of course there are different prices ranging from cheap (poor quality) to the ridiculously expensive but does everything. If you don't know what to ask for, you could be disappointed in what you get.

Do you want color or black/white? If you need to see the details clearly and you have good lighting throughout the time you need to keep watch, then a color camera is probably going to be the way to go. Color cameras are typically more expensive than black/white and they don't see very will in the dark.

If you only need to have a general idea of what is going on in the area then you can go with black and white. Don't misunderstand me, you can get a nice clear picture with a black/white camera but if you are looking to be able to identify someone and not have there be any question, then color is for you. If the lighting in the area is bad then color may not be the best camera for the job. If you only have lighting issues at night then you can get a day/night camera. That will get you a color picture in the daytime and a black/white picture at night.

Lens-

Now let's focus on the lens for a while. The type of lens you want will depend on what you want to see, how far away it is, and how wide of an area you want to see. For most applications you can get a lens that is adjustable to fit just about all your needs. There are some cases where only a very specific lens will work, but those usually only occur in high end jobs. If money is real tight, then you can get a camera that has the lens built in. I would like to caution you here and say that once you get a camera like this, you can't just go and adjust it to get the picture you originally wanted. So, make sure you get a camera with the right lens.

Quads/Multiplexers-

A quad processor will give you the ability to view more than one camera on one screen or one at a time. If you have a system with four cameras you can see all of them on one television screen or if you see something going on one camera you can choose to see only that location. Caution – the recorder you put on a quad will only record what the quad is allowing you to see.

A multiplexer is a step up from that. You can view your cameras any way you want. You can see each camera individually and multi cameras on the screen, in intervals. The playback, allows viewing the cameras in any form you like.

Recording devices-

First you must decide how long you want to record. If you have a business and you are closed on the weekends and holidays, you may want to record for at least 72 hours. If it's for your house and you go out of town for long periods of time you may want to consider a longer recording time. There is a time lapse recorder (very reasonably priced) that can record for 960 hours. That's 40 days and a whole lot of video to watch if you are looking for something that happened a week ago.

Something that has been on the market for a while and is finally coming down in price to something that is almost reasonable is the Digital Video Recorder (DVR). The DVR comes with so many features it's a little scary. First the picture quality is improved because you aren't viewing it from a tape that has been recorded over again and again and again. Second, it has a built in multiplexer that will let you view more than one camera at a time on the same screen. Third, it's easy to upgrade so that you can view your cameras remotely. So if you want to go on vacation and still keep an eye on things you can. Forth, the video is stored internally and it's a whole lot easier to view video without having to rewind and fast forward. Plus there is no need for a tape library. There are probably a few more things a DVR can do but these would be the most popular.

Monitors-

What do you want to see the picture on? Monitors can vary in size and picture quality depending on your budget and how much space you have. You can view cameras on your existing television or you can view them on your computer screen or over the Internet.

Wireless Systems-

A word about wireless systems. Wireless technology has come a long way. It's more reliable and the picture quality has improved greatly. I also like the idea that you can easily move the system. There is a system that just came out that has an awesome price. I have no idea how long the system will last, what the range is or if there are some environmental factors that can interfere with the picture. But if you are on a serious budget, this could be the answer for you.

I would like to thank you for reading this report. I hope this report has helped you learn a little more about camera systems. It's not easy to make an informed decision when you know very little about the subject. I hope now that you have read this report you have gained some insight into what kind of system would work best for you. If your system is driven only by cost, then please don't expect to get a great quality picture. If your system is driven only by features, then you had better open you wallet a little. I would highly recommend that whatever you are looking for, that you talk to a security consultant and discuss what is available for you in your price range.

Listen I have only scratched the surface when it comes to cameras. There are so many varieties available today it can be a little overwhelming for someone who doesn't know what they are doing. There are cameras that can Pan-Tilt-Zoom. There are covert cameras that would make James Bond proud. You just have to know what you want and how much you can spend. I'm sure you wouldn't go shopping for a car or a house and not know what your budget is or have an idea of what you wanted. Take this information and use it wisely

Use Of Home Security Cameras Increase

Unfortunately, the world is not as safe as it used to be. With crime in the home on the rise, more and more people are looking at options to make their homes more safe and secure. One option for home security that is becoming very popular is the use of home security cameras. These types of video systems can give a homeowner the sense of security and the peace of mind that they are looking for. Now, people can record their nanny or babysitter while they are away, see who is at the door before answering it, and find out if someone is on your property without having to go outside and possibly expose themselves to harm.

The home security camera options are vast. There are many sites on the Internet and a variety of catalogs that offer many different types of home surveillance equipment. You can buy a ready-made system for a reasonable price, or have a custom-designed system that is more costly but also very effective. They can also offer advice about the best kind of system for your needs and your budget.

There are both wireless and wired options for security cameras. Most people tend to go with the wireless choice, because anyone can install them in a short amount of time and they are easy to use. However, some people prefer the traditional CCTV option with wires to install. However, all of these types of security systems work with the equipment you already have. For instance, you can have live color images sent to your TV, or have them recorded on your VCR. If you need additional recording time, you can always choose to go with a digital recorder, which is more expensive but also gives you a lot more latitude in how much footage you need to record. These systems are weatherproof so that they work inside or outside, depending on your needs.

A homeowner can choose a simple camera, large or very small to mount in any place they desire. They can also get additional security items, such as motion detectors and night vision cameras. The variety of surveillance equipment is endless, and you can monitor any area you want to. The only factor is how much you are willing to spend on this kind of security stuff for your home.

One factor that is extremely important to consider when choosing a home security camera is camera resolution. A camera with a higher resolution will have a much clearer and sharper picture. So paying more for a higher resolution camera makes sense in the long run because you will have the kind of quality picture you need for your home security. Choosing a home security system does not have to be difficult or costly. Most security cameras can be installed easily and will provide you with the peace of mind you crave.

Security Camera System - Buyer Guide

Although the application of CCTV security has not changed very much over the past years, the tools and equipment have significantly. Surveillance cameras became smaller, cheaper and better, but the major breakthrough happened in recording equipment. Therefore many customers shopping for complete CCTV monitoring and recording systems are confused by such a verity of available products. Goal of this article is to guide buyers toward best possible and most economical type of CCTV equipment, based on intended implementation and requirements.

Selecting the right surveillance cameras.

It is virtually impossible to describe all types of available CCTV cameras in this short article. We will focus our attention on most popular and widely used camera types instead.

CCTV security cameras produce images using CMOS or CCD (Charge Couple Device) chips. Tiny, very low price CCTV cameras usually use CMOS technology, produce poor quality images and have very poor light sensitivity. Decent quality CCTV cameras use CCD technology. The size of the CCD chip is normally 1/4", 1/3" or 1/2". As a rule of thumb, the larger the size, the higher the quality of the image produced and the higher the price. However, higher density 1/4" and 1/3" CCD chips can now produce as good an image as many 1/3" or 1/2" chips. The number of TV lines in the security camera image is a measure of picture resolution (sharpness). The larger the number of TV lines, the better the resolution and hence, overall picture quality. Standard resolution camera may have 350-380 lines, over 400 TV Lines is generally considered good resolution while over 500 TV lines is considered high resolution. B/W chip cameras produce greater resolution and better light sensitivity, therefore suitable for use in dark areas where light conditions are poor most of the time. On the other hand color cameras offer more realistic and natural picture.

CCTV cameras are usually divided into different types based on the body of the camera used.

Professional grade cameras.

Have box type body with the ability to use different types and size of lenses. Exchangeable lenses enable this camera, to monitor objects from virtually any distance. Although for indoor use, they can be used for outdoor when combined with weatherproof housing. They are considered to be the most flexible and widely used by professionals for commercial installations.

Bullet cameras.

Bullet cameras are, as the name suggest contained inside bullet shaped housing. Most bullet cameras are weatherproof and sealed without the ability to use different lenses. Great advantage of bullet camera is the small size and integrated design, some bullet cameras will even have infrared LED future built-in. Infrared technology is simply LED light in infrared spectrum (not visible to human eye). This light will illuminate viewing area, making possible monitoring in complete darkness. This is great future, but it only works up to certain distance (usually between 10 and 50 ft. depending on model) Vary simple to install and estheticly designed, bullet cameras are great choice for residential and do-it-yourself installations where monitoring objects are within about 25ft from the camera location (with standard 3.6mm lens).

Board Cameras.

Board Cameras are basically fixed lens mounted on a circuit board. These cameras may be packaged in a small case (Mini Cameras) or dome (Mini Dome) or simply sold unpackaged, for mounting by the purchaser. Lenses in these cameras are either of a normal industry aperture or a "pinhole" lens of very small aperture. Pinhole lens cameras are often called "spy" cameras and may be mounted in a concealed way for covert surveillance purposes. The most popular examples of covert board cameras are smoke detector and motion detector cameras. Since the lenses in board cameras are pre-mounted, have a fixed iris and are usually of a short focal length (i.e. wide angle), their flexibility of usefulness is limited. However, this type of camera can provide a low cost solution in the right situation, particularly in a home environment.

We have shortly described most popular types of cameras, lets now discus, how and where they mite be used. Professional type cameras with C/CS mount lens attachment generally offer best performance and many important futures, like lens control output, Back Light Compensation and many more... Distance from monitoring object to the camera is not an issue, that is why ability to select different lenses, based on camera location is so important. Installation is bit complicated and professional installation strongly recommended. We recommend this type of security cameras for commercial installations. Most Bullet cameras in comparison, do not offer high resolution and lens selection flexibility, but are likely to be weatherproof, some will have infrared light built-in and most of all they are relatively easy to implement. Bullet cameras usually come with 3.6mm lens witch are considered to be suitable for most standard installations (good for covering small to medium size room or equivalent). For larger rooms or longer distances, cameras with 6mm or higher lens may be required. They are great choice for any do-it-yourself installation. Board cameras in contrast are widely used in covert camera installations, sometimes called Spy Cameras. Many wireless cameras are basically board cameras with built-in transmitter. We are not going to go into wireless cameras right now, as this would be enough material for completely new article. Board cameras are sold as plain circuit board, for integrating into hidden camera devices. They are also available in dome housing, as vary popular Dome Camera or integrated with Smoke Detector, Motion Detector, Exit Sign and so on. Most board cameras also come with 3.6mm lens although some will allow lens to be replaced. Over the time, most practical design has been Dome Camera with its esthetic appearance it blends into surroundings, especially with drop down sealing, great for use in stores, lobbies, gas stations and other public places. Practical solution for covert installation are also, Motion and Smoke Detector cameras, they are absolutely not substitute for your security alarm or fire protection. Cameras should always be selected based on the location of the camera (inside/outside), distance from the monitoring object, light condition and budget. When shopping for security cameras, customers are faced with the fact that they will need to select one or another recording device. The days of well-known CCTV time-lapse VCR recorder are almost over. Although some customers still prefer this old fashioned recording solution, it is well worth to invest some extra money to purchase a good quality digital video recorder (DVR). Digital recorder transfers analog camera video feed into digital format, and stores it on hard drive. There are two major types of digital recorders on the market right now.

PC Based CCTV Systems.

A special board and software installed on the computer will allow camera inputs and store video on the hard drive. Many people are under the misconception that personal computer with additional hardware installed, will do the job. This explains the hundreds of companies that have hung up a sign, taken out some ads and begun working out of basements and garages, holding themselves out to be DVR manufacturers and security specialists. The main problem with this type of CCTV recorders lies in the main component of it... Yes, it is a computer, designed to do unlimited tasks, but non well. The truth is that any computer based digital video recorder is, and will always be vulnerable to software crashes, hang-ups, system instability, virus related problems etc...

Stand Alone Systems.

Very similar in appearance and control functions to standard VCR recorders, are truly remarkable devices. Most video processing is done by hardware, therefore eliminating system crashes, video is also stored on hard drive in digital format. The basic operating system, usually Linux, is permanently stored on special processor, witch is impossible to overwrite or corrupt. Designed and manufactured with single application in mind, it is by far better in performance and reliability to its PC based rival. Some DVR systems will even have remote monitoring capability, useful when monitoring is required in different locations thru Internet or network. Most important futures to look for when selecting the right DVR recorder are motion detection and frame speed. The higher the frame speed the more fluent video recording. Motion detection will allow recording video from each camera only when motion is detected this is great for extending video recording time. Security Monitors.

Video from Security recorder could be displayed on regular TV monitor. It is OK to do it this way, for baby monitoring or residential application, when quality of the picture is not that important. However for professional installation, security monitors are as much important as cameras. They offer extended life of picture tube (necessary with any static picture, that can cause picture burnout) and much grater resolution. Cables and wiring. Finally any camera installation will require proper wiring. Good quality cable will prevent video degradation over long distance runs. It is recommended to use RG59 or RG6 coaxial cables as it is fully shielded and will prevent video loss up to 400 ft. Coaxial cables will require BNC connectors and proper installation possibly done by experienced technician. In short runs plug and play non-coaxial cables with factory installed BNC connectors may be used (up to 150 ft.). The plug and play cables are easy enough to install by not experienced users. Cables for CCTV cameras consist of two cables bundled in one jacket. One cable for video and one for power delivery. Conclusion.

Every CCTV system is as good and reliable as its weakest component. With this in mind, investing on highest quality and performance cameras, while purchasing low performance recorder, from economical and practical standpoint just does not make sense. For example, why use cameras with 500 TV lines of resolution with monitor that offers only 380 or less. All the benefit of high-resolution camera is affectively sacrificed by limited capability of monitor. Asking questions is important before purchasing video security system, and your vendor will probably be able to give more details and recommend equipment for specific needs and requirements.
