If you own a business, you know that theft occurs by your customersand employees. Employee theft exceeds $8.5 billion annually! 75% ofinventory shortages are attributed to employee theft. (NationalRestaurant Association). It's been reported that over 75% of internaltheft is undetected, and growing at a 15% annual rate (JusticeDepartment). All this dishonesty costs American businesses between ½%and 3% of their gross sales! Even 1% costs over one billion dollars aweek in employee theft.The results of all this? 30% of business failures are due to poorhiring practices by hiring thieves. Annual losses generated by poorhires, absenteeism, drug abuse, and theft amount to $75 billion peryear. (U.S. Department of Commerce-Atlanta Business Chronicle.). Whilewe can't screen your employees, you can keep an eye on them, and avideo surveillance system is one of the best ways to do it.When choosing a video surveillance camera system, there are several things to consider:Hidden Cameras vs. Visible CamerasWireless Cameras vs. Wired CamerasIndoor Systems vs. Outdoor SystemsVideo Recording vs. DVR RecordingHidden Cameras vs. Visible CamerasHidden Cameras The first thing you want to consider iswhether you want your cameras to be visible or not. Modern technologyhas reduced a video camera down to miniature levels. Hidden cameras canbe hidden behind a pinhole, and can be put in practically any everydayitem in your house or office, in a briefcase or backpack, or evenhidden in a hat or behind a button. The advantage is that the criminalwon't know they are being recorded, and you should catch more theft.Hidden cameras could be more expensive then visible cameras.Visible Cameras A visible camera system consists of anynumber of visible cameras from the black dome cameras you see in moststores, to the old fashioned kinds on brackets pointing at you at thebank. There are also high resolution cameras that can zoom in to tightdetail. The advantages of these types of systems is that your criminalwill know they are being watched, and that should deter a lot of crimethat normally would occur without the cameras.Even a series of dummy camera's, camera bodies with no working partsexcept a flashing red light, are proven to deter crime. If you don'thave the funds for a working video surveillance system, just installingfour to twelve dummy cameras fools the criminal into thinking you havea real system in place.Wireless Cameras vs. Wired CamerasYou have two choices for the type of surveillance system, wireless and wired. Both have advantages and disadvantages;Wireless Camera SystemWireless camera systems are thefastest systems to install, as you just need to mount the cameras, hookup the wireless receiver in the back room, and wire it all together toa power box and some type of system to record the video.The advantages of wireless cameras are that they can be installed inlocations that are difficult, if not impossible to wire. They can bemoved to different locations easily, as often as you like, and if theneed arises, they can be hidden inside a moving object like inside yourcloth, cap, briefcase or carrying bag etc.To overcome the disadvantages of a wireless camera, you should buyone with a higher frequency transmission band of at least 1.2GHz orabove. If you need to take video from the wireless camera a longdistance from the receiver, or there are walls, metallic or steelobstacles between the wireless camera and the receiver, you should buya wireless model with a higher transmission power, that is, atransmitter with longer transmission distance. Another good idea is touse a high gain antenna for the transmitter or receiver, which willimprove the signal transmission/reception.The disadvantages of wireless cameras are that the video streammight be disturbed or influenced by moving objects or strong radio oreven telephone frequencies. Video/audio transmission is limited withinthe prescribed transmission range. These disadvantages will not occurwith a wired camera.Wireless camera systems are also more expensive than wired systems,as they require a lot of receivers and transmitters to received thevideo that normally would run in the inexpensive wires. However, thecosts are usually worth it, as it could cost less to install, and lessto relocated. Overall, the video/audio signals from a wireless cameraare less stable than a wireless camera.Wired Camera SystemsWired camera systems are more stable dueto the cable, which doesn't have the interference problems associatedwith wireless systems. You need to run a video cable to each camera inorder to get a video feed. You will have to run the wire either throughthe walls and ceiling, or have it exposed on the wall. While the costof the system is less than a wireless system, it will require more workto install, and if you are paying someone, it might cost more thanbuying a wireless system.You should look at the total costs to purchase and install bothsystems and go with what is best for you. Overall, the video/audiosignals from a wired camera are more stable than a wireless camera.Indoor Systems vs. Outdoor SystemsDepending on your needs,you will need a camera for indoor or outdoor needs. If you need tomonitor your loading dock, you will need a camera that can withstandthe elements. Unless it's specifically sold as an outdoor camera, aregular camera can't withstand the beating from Mother Nature that aweatherproof camera can endure.You can find many types of outdoor camera, dome, bullet, andstandard. All are enclosed in waterproof cases and some even haveheaters for cold areas. You can also buy hardened cameras that willwithstand direct hits from bats and hammers. These are recommended inhigh crime areas.Video vs. DVR RecordingYou need to determine if you want torecord the activity, or just hire someone to monitor it. It's a goodidea to record the video so you can give a copy to law enforcement forfuture needs. You have two choices, VCR or DVD.VCR allows you to record the video with a Video Cassette Recorder(VCR) directly to a VHS tape. You can use a bank of standard VCR's, orthere are high density VCR's that allow you to record days of video.Some come with motion detectors and won't record unless the videochanges. The disadvantages are that you have to know about what timethe event occurred, or you will have to review all the tapesequentially, or on fast forward.The latest technology is using a DVR or PC based DVR system torecord the video to disc. The advantages are a DVD can be burned fromthe digital recording. This is the easiest system to review yourrecordings, as you can jump ahead to any point in the recording, unlikethe VHS tape. The initial cost will be larger than a VCR system, thoughyou won't need to buy tapes, and the ease of use will be worth theextra money for a DVR based system.You have two types of DVR systems, DVR recorder and PC based. DVRrecorders feed the video directly into the hard drive or disc on therecorder and you either burn the disc, or back up the hard drive. Thesecome in a variety of sizes, from standard sizes for indoor uses, downto field use DVRs the size of a pack of cigarettes that can record upto 60 hours of video from a hidden surveillance camera.Your other option is the PC based surveillance system that uses aPersonal Computer, a video capture card, and software as a controlcenter that can not only record the video and burn it to disc, a quadcan be installed to monitor the feeds on real time over a computerscreen, and break it up into quadrants to monitor multiple cameras atthe same time, in real time.We have only just scratched the surface of video surveillancesystems with this brief overview, and future articles will focus on thepros and con's of what is out there, and is it right for you.
