Fake Security Cameras

Are fake security cameras effective? The answer is a resounding "Yes."

Fake security cameras have helped to prevent many crimes. Mounted in high profile, totally visible locations, these cameras are not hooked up to anything, they mostly operate for a long time on batteries and sometimes have a few flashing lights or other obvious characteristics to make them look as if they are doing something.

Many a would-be robber has changed his or her mind about entering someplace illegally after spotting one of these dummy security cameras looking right at them. With today’s technology, an inexperienced thief really has no way to know whether or not he’s looking at a wireless, state of the art surveillance device or a fake security camera. Some of them actually pan back and forth, although these require more frequent battery changes.

Fake security cameras are especially effective in areas that you expect to be covered by security cameras. For instance, many of the cameras in subway stations around the world are fake security cameras and nobody can tell the difference. During hard times, when the crime rates inevitably rise and cities are strapped for cash, the ratio of fake cameras to real ones was about 2-to-1 in some metropolitan areas.

Knowing that the fake cameras would be regarded as real, the fakes were sprinkled in among the real ones to provide an extra incentive for would-be robbers and thieves to practice their trade in another location. Except for the lack of recorded footage provided by the real cameras, dummy security cameras are almost as effective in reducing crime rates in subways as the real ones are.

Only sophisticated thieves can tell -- at a distance -- whether they are being observed by a real security camera.

Online Security Camera System - Buyers Guide

Written by ..ArtBGmail on at 11:42 AM

Although the application of CCTV security have not changed very much over the past years, the tools and equipment have significantly. 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 cameras.

It is virtually impossible to describe all types of available ones 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 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 ones 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 types 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 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. They 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 are basically board ones 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 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 aesthetic 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. They 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 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 through 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 CCTV 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.

A Look at Wireless Security Cameras

Written by ..ArtBGmail on at 11:40 AM

Wireless Security Cameras

If you need to partially conceal your cameras from view, wireless security cameras are the way to go. Locations such as banks use a combination of wireless and wired, visible and hidden cameras to intimidate potential robbers, but continue photographing them even if they disable the wired cameras.

Las Vegas casinos do the same. Look around you the next time you enter a casino or a bank. There are cameras evident and these are for “publicity” purposes. That is, they are there to intimidate a potential robber or petty thief from doing anything, knowing that their actions are being recorded. The owners of these establishments want you to see these cameras and they want you to think twice about doing anything naughty in their places of business.

Then there are the hidden cameras. Almost always wireless so they can be placed anywhere, they photograph through small holes in the walls or ceilings, or from behind specially designed ordinary devices you’d expect to find in the location. Wireless security cameras are the ones that provide information to the police about who may have committed some crime after they disabled the visible systems.

Wireless cameras can be battery operated. That is, they are used to monitor the activities of people for a limited amount of time. Their advantage is that they can be placed in a variety of easily concealed positions, much more so than a camera that requires a wire to be connected to both its power source and a recording device.

Lately, these cameras have been built into clocks, children’s toys and other common household devices and have been nicknamed “nanny-cams.” They came into more popular use to catch babysitters and nanny’s who watch over precious youngsters who may not be talking yet. Horrible abuse sometimes occurs when unbalanced adults are left in charge of toddlers who can’t speak.

Concerned parents started using these devices to record the actions of the adult in charge while they were gone. Then the couple could play back the tapes and see what went on in their absence. Some of these tapes were so outrageously awful in what they captured on videotape that they led to prosecution of the adult offender and oftentimes ended up on national tabloid TV shows. Since then they have become a built-in, cleverly concealed device that’s quite often found in homes where young children are being watched by hired help.

The Bar is One of Businesses Most Vulnerable Areas of Theft

Bar Security Camers

Shrinkage, the average loss due to theft, spillage and waste, nationally is approximately 23 percent on liquor and draft beer, about 10 percent on wine and 2 percent on bottled beer*. That’s a lot of money. It could mean your profits for the year! Eliminating shrinkage can mean the difference between financial success and bankruptcy.

Theft alone is the largest source of losses in bars. Opportunities are plentiful for theft behind a bar. Bartenders work many hours without direct supervision. Those who steal from the bar do so because it’s easy, hard to detect, and nearly impossible to prevent.

The temptations posed by handling large sums of cash and dealing with a liquid inventory on a day to day basis can be overwhelming. At some point, even the most honest bartenders will contemplate stealing cash, and give out free drinks to friends or bar regulars.

Bar Video Surveillance can Help Eliminate Dishonest Bartenders

You need to send a message loud and clear to your staff that theft will not be tolerated. Bartenders know they will be held accountable for their actions with surveillance video systems.
While you might not want to pursue criminal action against a bartender for embezzlement or a similar crime, video documented theft is solid grounds for termination. A mere wrist slap does nothing to discourage others from putting their hands in the till.

Consider the predicament that Bob had when he terminated his favorite bartender. "After installing the GeoVision camera system, it became apparent that Judy was taking taking money and giving away the farm. She was bringing in a ton of business, much of that was because of all the free drinks she gave away. I hated to let her go, it hurt our bar customer traffic at first. But after looking at the bottom line, we knew we made the right decision."

Caution: Most bars installing the GeoVision Bar Surveillance Video System from Camera Security Now fire at least 1 bartender after the initial installation.
