How To Find The Best Wireless Security Camera For Your Home

Written By:

Wireless security cameras are designed for both indoor and outdoor use. A wireless camera requires no wires between the camera and the receiver. They are easy to install and can be moved from one location to another. Wireless cameras are available in many sizes and forms. The cameras capture black and white, color and infrared images. The security system connects to any computer, television or digital video recorder for easy viewing. To find the best wireless security camera for your home, decide how many cameras you need.

If you want to monitor the entire perimeter of your home, then you will need several cameras. Consider the image quality when choosing a camera. An HDTV camera has a higher resolution and will cover a larger area than a CCTV or an IP camera. The benefit of an IP camera is the fact that you can connect multiple cameras to your digital video recorder. IP cameras can connect to the Internet providing remote viewing from any computer. An Ethernet switch provides the power and the Internet connection. HDTV cameras are useful when you need to capture clear and precise images such as license plates or faces. Today’s technology allows home security systems to be enabled or disabled by using a computer or smartphone.

To monitor the inside of your home, you can install burglar alarms on your windows and doors. Carbon monoxide, fire and flood alarms can easily be added to your home security system. Carbon monoxide is known as the silent killer because it has no smell or taste. Heat detectors are useful in areas of the home such as laundry rooms, garages and other places. Fire alarms can be monitored by a security company to contact you or the fire department. Flood alarms are used to detect the presence of water or moisture in the event you have pipes that burst or leak. They also monitor moisture levels to warn you of the presence of mold and mildew. Inspect these sensors on a regular basis to prevent the buildup of dirt and debris.

Home burglar alarms are helpful because they alert you to the presence of an intruder whether you are home or not. If you choose to have your burglar system monitored by a professional security company, they can install glass break sensors on your windows. They use single or double break technology to detect glass breakage. Single break technology will trigger the alarm from the sound of glass breaking. Double break technology must hear a thumping sound followed by the sound frequency of glass breaking before the alarm is triggered. Monitored home burglar systems may have to be adjusted to prevent false alarms. Many cities have penalties for frequent false alarms. False alarms cause local law enforcement to use resources that are needed elsewhere in the city.

Emergency health response systems are a good choice for people who have health problems, the elderly or just for the peace of mind. These emergency response systems can alert local authorities to the presence of a medical emergency inside your home. Panic buttons are located on the home security system’s keypad and also by small remotes. You can choose to have the system contact you or the local emergency personnel. There are hidden indoor security cameras that can monitor your babysitter or any situation. These cameras are small and discreet and provide helpful information. They connect to a small digital video recorder and can be wired or wireless. Consult a professional home security company to determine which security system will work best in your home.

Combining a home security system with home safety tips will improve the security of you and your family. Don’t hide a key under the door mat or anywhere else near the home. This will be the first place a burglar will look. You can buy locks for your doors that require opening with your fingerprints. This is a good idea if you are constantly losing your house keys. If one of your locks on your door breaks, be sure to replace it right away. Two cylinder locks are available but they require a key to open the door from the inside and out. This can cause a hazard if there is an emergency in the home and you need to leave quickly. Install deadbolt locks on sturdy doors that lead into your home. The deadbolt should be attached to the door’s wood frame. Have a professional install your deadbolt locks if you’re not sure how to install them. Access doors into your home should be made of steel, wood or fiberglass. This will help prevent a quick entry into your home by simply kicking it. Install modern kick plates on doors leading inside your home. Hollow doors without good locks are easily kicked in by burglars.

Outdoor lighting can improve the look of your home. It also helps to deter crime. Most burglars don’t want to be seen and they like the cover of darkness. Install solar lights and motion detection sensors to lower your energy bills. If you have a privacy fence, you can add a beware of dog sign even if you don’t have a dog. Place home security signs and decals on your windows and doors to alert a possible intruder that you have security. You can also purchase fake security cameras that look like a real working home security camera. Driveway and garage sensors can be installed to detect movement. Keep the garage secured and locked at all times. Don’t leave the garage door open even when you are at home. This gives people who pass by the opportunity to stake out your garage. Lock the inside latch of your garage door with a padlock. Check your garage door remote to be sure it has rolling code technology. This technology changes your garage door code each time you enter the garage. If you must replace your garage door, choose one without windows to prevent a burglar from seeing if there is a car parked in the garage.

When you have a home security system installed, be sure to keep it activated even when you are at home. Many people either don’t turn it on when they are home, or they forget to activate it when they leave. The key to protecting your family and home is to use the alarm system. It only takes an intruder a few minutes to enter your home and steal your possessions. Most burglars are looking for items that can be sold at the local pawn shop. Be sure to have your driver’s license number engraved on your expensive electronics. The burglar won’t be able to sell your items very easy. Keep curtains and drapes closed so they don’t reveal your home’s contents. Install sensors on all of the windows of your home. If an intruder tries to enter through the windows, an audible alarm will sound. This could be enough to send the burglar to another home.

Store your valuable jewelry, cash and weapons in a locked safe or a safe deposit box. If you purchase a safe for your home, you don’t want a burglar to be able to carry it out. Have it bolted to the floor, or be sure it is too heavy to be carried easily. The outdoor storage shed should be kept locked at all times. Installing electronic gates will help to keep a burglar out of your backyard. If you have a privacy fence, a burglar can get into the backyard and remain invisible to the neighbors. Get to know all of your neighbors in your neighborhood. Join your local crime watch program or start a new one. Most law enforcement agencies have crime prevention programs that you can join. Learn about the crime risk in your area. When you go on vacation, notify a neighbor to watch your property. Install timers for the inside lights of your home. This will make your home look like someone is home even when they’re not. If everyone in the neighborhood becomes familiar with who should or shouldn’t be there, then the community is safer. Most burglars will park down the street before walking up to your home. Neighborhood watch programs teach people to report suspicious vehicles.

Apartment and condo residents have the same security needs as anyone living in a single-family home. When you move into an apartment or condo, have the maintenance staff change the locks. You don’t know whether the old tenants still have a key or not. Getting to know your neighbors is important. Report any suspicious people or activities to the neighborhood’s security team or local law enforcement. Reinforce sliding glass doors with a wooden bar, and never leave your doors unlocked. Purchase renters insurance to cover your possessions in case they are stolen. Don’t go to the laundromat at night, and be sure the apartment’s parking areas are well-lit. Ask the staff if you are allowed to install a security system in your apartment. Call a professional burglar alarm service to install the security system.

When you purchase new electronics don’t put the boxes out with the regular trash. This will alert a possible thief to the fact that you have this item. Break the boxes down and place them in plastic garbage bags. Online social media sites are a great way to show family and friends your vacation photos. They can also be a tool for an intruder to know that you’re out of town or when you will be leaving. It’s hard to imagine but the risk is still there. Take care about who you tell about your vacation plans. Leave a spare key with a trusted neighbor or family member. Have them check on your property while you are away. They can pick up your mail, newspapers and any flyers attached to your door. It would be ideal for them to open the drapes in the morning and close them at night. You can also ask your neighbor to park their vehicle in your driveway. You want to convey the message that someone is at home.

If you are selling your home without the use of a real estate agent, there are a few security precautions you should keep in mind. Show your home by appointment only. Don’t set an appointment to show your home when you are alone. When you decide to have an open house, clear the rooms of valuables and electronics. It’s best to sell a home with a minimum amount of personal possessions. If you use a real estate agent and they want to place a virtual tour of your home on their website, then be sure there are no expensive items or electronics in view. Some criminals check these out to choose a property to burglarize later when no one is home. If you are buying a new home, have the locks changed as soon as possible.

A safe room is a room that is reinforced with a lot of concrete and steel. They are used for emergencies such as bad weather or a home intrusion. Adding a safe room to your home will improve your home’s security plan. Keep bottled water, snacks and a cellphone in your safe room. A phone that is connected to a land line is also helpful to phone the authorities from inside the safe room. A land line phone will give your home address to local law enforcement agencies just by dialing 911. If an intruder enters your home, you can run to the safe room. Teach family members about home security safety tips and the use of the safe room. Search the Internet to learn more about installing a safe room in your home. There are many ways you can improve the security of your home. When you combine many security techniques they become a powerful deterrent for an intruder. If you make your home difficult to enter, and you have outdoor surveillance equipment, an intruder may decide to go to another home.

Fake Security Cameras

Written By:
Monday, March 5th, 2012

Deception, as far as security is concerned, plays an important role. Militaries have been deceiving opposing armies for centuries. Pioneers making their way west would routinely place gun barrels out the sides of the Conestoga wagons. This gave the appearance of multiple armed pioneers, when in fact no one was behind the rifle barrels. Bands of marauders, not knowing for sure, would not attack for fear of losing the battle and their lives. Wooden cannons made to appear as if real would be placed on battlefields. The opposing army many times would hesitate, and make a graceful exit from the field of battle. Using fake security cameras employs the same principles of deception that has been used for years.

Creating Doubt

Simply giving a criminal a moment of hesitation can be enough to cause them to move on. The deception must be well staged however. Spotting a camera invokes a visceral reaction in criminals and others up to no good. People that have committed crimes, and ones thinking about it, many times suspect others may be aware of their transgressions. Many call it a guilty conscience. However, it is not guilt from doing wrong. It is fear of being caught. Criminals when they see a camera lens staring at them as they make their way to a window or back door will stop. They immediately wonder if they have been spotted. They also wonder if the camera is high quality enough to identify them in the dark. Most will make a quick exit from the property.

The Ideal Fake Security Camera Is Real Except For

High quality fake cameras are real cameras without the electronic components. The housing is real and the cables are in their proper places. Ideally, you want one that has a red recording light and motion activation. The camera will come equipped with a battery pack that operates the motion sensor and recording light. However, placing a motion activated fake camera in a high traffic area will quickly deplete the battery. For the most part, homes would not have this type of activity. Businesses employing decoys would need to consider this when placing the cameras.

Make It Look Real and People Will Assume It Is Real

Placement and having the correct camera in the right spot is important. The cameras located outside need to be obviously designated for outdoor use. Criminals paying attention might begin to wonder. Use dome cameras at the front door. Real dome cameras conceal where the lens is pointed. People expect to see this type of camera at entrances. They also provide 360 degrees of coverage, and are tamper proof. Cameras placed with no obvious target area will raise questions about their effectiveness. Also, ensure the camera lens is not pointed at the ground, the sides of the structure or pointed straight up.

Play Your Part Well and Others Will Play Theirs

You can call placing fake security cameras a process of elimination. Would be burglars that are serious about maintaining their freedom will make on the spot assessments. Simply by driving by a potential target, a burglar will eliminate that house as a target, if security measures are obvious. The potential payoff is calculated by assessing risk. Like any professional contractor, the cost of the job is estimated by the amount of effort that must be put forward. A plumber, for example, will lose profit if they misjudge the effort and materials needed. A criminal that does this loses their freedom. Your part as a homeowner is to ensure the cameras always have fully charged batteries to operate the motion sensors and lights. Use widow decals and yard signs to warn of video surveillance.

Many Crimes are Crimes of Opportunity

Fake cameras are not just for the exterior of the home or business. You may have simply assumed that an intruder will never see the inside of the home if they leave after spotting cameras around the exterior. As a homeowner, stop and calculate how many people beside family members have been inside your home over the course of days, weeks or even months.

The cable installer is all over the home, they are in the basement, attic and every room inside. They are not professional criminals however. The large screen television or the new laptop may be more appealing than their sense of right or wrong. They overhear a conversation and realize the home will be vacant at a certain time. They plan and they decide to supplement their wages. Then they spot the camera mounted high in the corner with blinking red lights. It is a motion activated one. You as a homeowner have just thwarted a crime.

This is a prime example of why the cameras must be installed as if real. The cable installer, an electrician or any contractor has more mechanical knowledge than the average person does. You may think well they can spot a fake. They can if the fake camera is not installed properly. Quality fake cameras have real cables attached and many even come with AC adapters for use with household current. Mount the cameras in logical places and plug them in if applicable. Make sure the cables are run into the wall if they need to be. Criminals are aware of wireless cameras so the fact that cables are not protruding everywhere does not raise any questions.

However, they may look for a receiver. Make a point to keep the office locked when workers are present, if they need access be there to keep them from looking to closely at things. Have a file cabinet and keep it locked even if it is empty. Locked doors and secured cabinets all maintain the illusion. Individuals see the cameras and then find doors and file drawers locked they soon put the pieces together. This is doing your part as a security conscience homeowner. They have no idea if the receiver is in there. Unless they have access to your computer, they cannot tell if it is the receiver either. This is not to say that professional contractors are dishonest. The truth is many break-ins are done by individuals that have been in the home before, in some cases, more than once.

By no means, is any statement meant to indicate, or give the impression cable installers or any professional contractor is dishonest. The statement is simply to illustrate how many people may have been in a home over a certain period.

You may be thinking that if all of this has to be done why not just go ahead and install real ones. The cost is the reason why. Budgetary constraints are a major factor. The steps you take to maintain the illusion cost you little in dollars. The payoff however, is well worth the effort. The material costs are just a small percentage when compared to having real cameras professionally installed and monitored.

To maintain the deception, it is wise to install the fake security cameras yourself. The local contractor unwittingly may tell their colleagues or partner. Security is about keeping secrets. For example, armored car drivers never use the same route twice in succession. Their manifest will never have an inventory of contents. It is all about maintaining a security profile. The unknown will make intruders move on to the next house.

Criminals Do Not Want To Work Hard So They Spend Time Looking For Easy Targets

Your home says a lot about you, how it is maintained, what the lawn looks like and so forth. Cameras tell intruders you are paying attention. Fake Security CamerasThieves look for people who appear unaware of their surroundings. Toys or tools strewn about the driveway and yard tell people you may not be paying attention. Lack of obvious security is an open invitation. You have heard the term keeping up appearances. It applies to your security profile, as well.

An expensive looking surveillance system loses some of its impact when someone sees a cheaply constructed hollow core front door. The lock is not effective and easily defeated. The home profile as a whole must indicate you are aware of things, and are pro-active when it comes to security.

You have worked hard for your possessions and your family’s safety is the number one priority. It requires some effort to install fake security cameras and you must apply all the window dressing to go along with it. However, by not doing so you have set yourself up for an intrusion. Do not install cameras in trees with no obvious means of power where leaves and branches block the lens. This tells everyone you have thought about security but have only put a half-hearted effort into it. Tinkering around the edges when it comes to security is obvious to criminals. The efforts send a signal you are not serious, and frankly may not have a clue.

Like a Good Lie Good Deception Mixes In the Truth

Professional bodyguards put tremendous effort into deception. They mix the real in with the fake. When driving their client to and from places they use several cars all the same make and model. No one knows which vehicle to target. Anyone with ill intent is confused, overwhelmed and the majority of the time will give up any attempt.

Unlike money, you can have too many cameras, in some instances. Large estates are expected to have cameras in specific locations. Cameras would be mounted at the gatehouse or covering an entrance gate. The cameras would be mounted to screen visitors or capture vehicle license plates. Anyone would expect a large number of cameras to be present. There would be several covering the perimeter, the backyard, pool area and driveway. The cameras even if fake will still give the correct impression. However, having a large number of expensive looking cameras located around a modest dwelling can send the wrong signal.

It is perfectly acceptable to mix fake security cameras in with real ones that capture and record images. Many homeowners want a real camera to be able to see who may be at the front door. However, they realize most burglars gain access from back doors, upstairs windows and so forth. Decoy cameras can be placed in among real ones to increase your home’s security. Once again, place them in logical locations. One must cover the backyard and any doors or windows where anyone could gain entry. Homes having security gates at the end of their driveway would want one there, as well. These are logical locations and no one would question their position.

Parents regardless of economics want a camera to be able to monitor their child’s care while with a babysitter. They have prioritized, and placed the camera where they foresee the highest risk. In this case, fake cameras can be used in other areas of the home for the babysitter’s benefit. The babysitter has in all likelihood, determined the nanny cam is real. Therefore, others mounted high in the corners of certain rooms will be real to them, as well. This goes back to keeping honest people honest. Let them know you are paying attention and aware.

Prevention is the motivation behind fake security cameras. Let people know up front you are watching. No one wants to take the chance of being recorded committing a criminal act or even a very dumb act. Workers in your home when you are away may decide to help themselves to leftovers in the refrigerator. Seeing cameras mounted will stop this type of activity. Nosy neighbors will not snoop while your back is turned. This brings up another point. Do not tell your friends and neighbors. Once you tell a secret, it of course, is no longer a secret.

Part of good deception is being mysterious about certain things. You must be closed mouthed about your security measures. When people are not sure they hesitate, and many times will not follow through with what they intended. You must maintain appearances to have the proper security profile that will protect your family and possessions.

Professional Security Camera

Written By:
Friday, November 18th, 2011

The professional security camera digital video recording system is rapidly becoming one of the most popular security and surveillance documentation and monitoring tools in use today.  Thanks to advancements in digital technology, not only is high-quality color digital video possible, but its also economically priced, easy to install, and versatile in application.

A professional security camera digital video recording system is any system that captures digital video images and records them on some type of storage medium for later use.  The difference between a digital video recording system and an analog video recording system is how the video image signal is created; however this lends itself to other differences such as how the video “footage” is stored, how it is transmitted, and what kinds and types of images are available.

First, let’s look at how an older analog video recording system works, and then we’ll compare it with the newer professional security camera digital video recording system.  Both systems have a camera that “captures” the video images and a recorder that stores those images for playback at a later time.  Each system may also use monitors to display real-time (live) video as it is captured.

Without getting too technical, an analog digital video camera contains a sensor chip.  This sensor chip converts the image’s light energy, which is focused onto it by the lenses, into electrical energy that can be measured and used to create a video image.  The images are transferred from the professional security camera to the video recorder and monitor using a coaxial video transmission cable.

The analog video recorder records the audio and video as magnetic signals, usually on a magnetic tape.  What is actually happening is that the camera is taking several pictures per second but it appears to the human eye as smooth motion video.  This is the same way its precursor, film video works.

Film cameras actually take several film pictures or photographs per second.  Once the film is processed or “developed” a projector rolls the film from the full reel to an empty one.  As the pictures pass in front of the projector lens in rapid succession, they give us the impression of a moving video.  Since film is basically a linear storage device that can be hundreds of feet long, the term “video footage” was used to refer to motion pictures.

Since analog video is stored as a magnetic pattern, each time the recorded video is played it has the potential for degrading the signal.  In addition, time can also degrade the magnetic signal as the signal’s weaker points can fade.  Analog video is stored on a variety of formats but the most popular magnetic video tape is VHS or BETA.  The video recorder either uses a video tape loop that re-records after reaching the end of the tape or individual video tapes that must be replaced when the recorder reaches the end of the tape.

Professional security camera digital video recording systems use basically the same technology to create digital video.  Cameras record image light energy and transfer it into electrical energy.  However, the fundamental difference in a digital video camera is that the camera also contains an analog-to-digital converter which turns the analog video signal into a series of 1s and 0s, or in other words, digital or binary data.

This simple change has revolutionized the professional security camera industry.  Since the digital video signal is now stored as a digital file, many other technological changes have taken place that have made digital video recording systems differ from their older analog parents.  Here are some of the differences (some are more advantageous than others) of using digital video recording systems:

  • Personal Computers can now be used to control and record the cameras;
  • Standalone digital video recording systems save their data to Digital Video Recorders or DVRs that have the potential for storing thousands of times more data in the space of an analog medium;
  • Cameras can be networked, controlled, and monitored using the internet;
  • Components of the system are smaller, lighter, and more efficient using less energy;
  • Digital signals are 1s and 0s – they do not fade or degrade like analog signals can.

Professional security camera digital video recording systems have become so popular that they are now the norm in the security video industry, rather than the exception.  If you are interested in learning more, check out Security Camera King’s “CCTV Learning Center.”

Portable Surveillance Camera

Written By:
Friday, October 14th, 2011

Portable Surveillance cameras are becoming more and more popular these days especially with technology advances yielding smaller and smaller cameras. Generally but not always, the smaller the camera device the easier it is to hide or disguise and the smaller it is the easier it is to make it portable.

Portable Surveillance camera systems differ from standard counterparts simply because they are portable. A typical digital surveillance camera is not portable, in fact it is usually securely mounted to some surface with screws.

However, if a system is portable, what does that mean for the “system.” It means that the camera and the DVR must be in the same “unit” in order to be entirely portable. In addition batteries or some sort of portable power pack are also required for a portable surveillance camera.

Portable surveillance cameras have many applications. “Helmet cams” are one such application that enables “hands free” portable video recording because the unit is attached to a helmet that is worn by the user. Some examples of helmet cam use include skydiving, the aerospace industry, medicine, mining, and down-hill skiing.

Another type of portable surveillance camera is often referred to as a “bumper cam.” Although the camera is usually not attached directly to the bumper, an on board high speed digital color video camera system is normally attached on a vehicle with the camera’s target area being somewhere behind or at the rear of the vehicle. This type of camera set up is often used to aid the driver when backing up or for monitoring the “rear view” when abnormally large payloads make this difficult using just mirrors.

Perhaps one of the most frequently used overt applications of a portable surveillance camera is in surveillance and security of mass transit vehicles.  School buses are now being equipped with on board high speed digital color video camera systems to monitor the students’ as well as the drivers’ activities.  The mere presence of a portable surveillance camera unit in school buses has drastically reduced the number of disorderly conduct cases among transporting students.  When incidences do arise, the system can provided a recorded audio/video account providing protection to both students and drivers.

Subways and mass transit buses are employing on board systems not only to provide security/surveillance but to deter and prevent false injury claims. Mass transit vehicles equipped with portable surveillance cameras systems have shown drastically reduced crime rates. In addition, these systems can provide monitoring of passengers in the event of an accident, helping to keep false injury claims at a minimum and insurance rates low.

Yet another popular application of portable surveillance cameras is legal work for police. FBI, DEA, etc.. In addition, police departments across the world are instituting the use of on portable surveillance cameras to provide evidence and monitor activity of potential law breakers. Highway pursuits, disorderly conduct cases during police stops, and an array of other activities are recorded and may be used as evidence if necessary. They also can protect officers from false claims of inappropriate behavior.

Portable surveillance cameras consist of a small, compact color digital camera, a self contained power supply if necessary, and a high speed video processor and recorder. Most systems also include a small liquid crystal display or LCD monitor.  Many on board systems record video to compact flash cards or other types of “flash” memory so that vibration that could interfere with hard drive use has no effect on recording.

There are several additional features available today for portable surveillance cameras. Systems can be purchased that include an optional Global Positioning System or GPS module. These systems can record the coordinates as well as the speed of a vehicle and display it on-screen superimposed over the video captured by the system’s camera.

Timer kits are also available. They are useful for racing applications where lap times, equipment changes, and over all race timing are required. This can be an invaluable tool for any race team.

As you can see there are a wide variety of applications for on board high speed digital color video camera systems and there is also a wide variety of accessories and features that are available to enhance their productivity. Speak with one of our digital security experts to determine which system and features are right for your application by contacting them via on-line Live Chat or by telephone at 866-573-8878 Monday through Friday from 9AM to 6PM EST.

Digital Color CCD Camera

Written By:
Friday, October 7th, 2011

Most video security cameras today are digital color CCD cameras or digital color CMOS cameras.  How do you know which to purchase?  Is one better than the other?  What does CCD and CMOS mean?   Read on to find out the answers to these questions and more.

First let’s describe a digital video security and surveillance system.  It normally consists of three components; the camera(s), the Digital Video Recorder, and a monitor(s).  The camera’s function in this system is to capture a video image created by light reflectance and transform it into an electronic image based on electrical impulses.  Both live and recorded material is played back by the DVR and may be seen by watching the monitor.

So now that we have a general idea of what each component does, let’s talk specifically about the camera and the security camera CCD.

A digital video camera works by using a combination of mechanical (lenses) and electronic (Integrated Circuit or IC chips and printed boards).  Whatever direction the camera may be pointed in, the area that you will see as a point of view from the camera is called the camera’s field of view.  The field of view is the specific area that will constitute the video image.

The field of view can be made larger or smaller depending on the focal length of the lens.  A standard lens has one focal length and therefore one field of view.  Varifocal lenses can vary their focal length (either manually or remotely).  The field of view contains objects that reflect light.  This reflected light is captured by the lens and when in focus, the lens focuses the reflected light on a sensor chip which is usually only 1/4 to 1/3 inch square.

This sensor chip, in our case, is the security camera CCD or Charged Coupled Device (There is another sensor that is used for the same purpose called a Complementary Metal Oxide Semiconductor or CMOS.  Although it works a little differently than the CCD it produces the same results).  As the focused light strikes the security camera CCD, tiny pixels on the sensor emit a very small but measurable electric impulse.  There may be more than one CCD and there maybe the use of one or more filters involved as well.

Once the light strikes the security camera CCD, the CCD gives off its electrical impulses and these are measured and interpreted by the analog to digital processor IC chip.  This is when the video image becomes digital.  As the processing continues in the camera, the camera’s Digital Signal Processor or DSP, in essence another IC chip makes adjustments to brightness, color intensity, contrast, etc. to make sure the video image is of the highest quality.

Once the video image information now binary or digital, is sent to the DVR the DVR stores it or plays it live.  Either the camera or the DVR compiles the binary data and creates a digital video file out of it.   These digital video files are the same type of digital video files that can be watched on a personal computer.

The digital color CCD camera (and the CMOS) have a unique feature about them that makes it even more versatile.  The CCD (and CMOS) is inherently able to see infrared light.  Infrared light is invisible to the human eye, so this makes for a very powerful, useful security device.  Most night time infrared cameras have an array of Infrared producing Light Emitting Diodes or IR LEDs that are arranged around the lens of the camera.   The human eye cannot see their light, but to the CCD, they work like using a floodlight.

In addition to the array of LED’s around the camera lens, IR LED illuminators may also be used.   Illuminators are just a group of more IR LEDs to add more light to the picture.  Some illuminators boast IR ranges of as much as 300 feet when using the illuminator along with the camera’s own lights.

Incidentally, since this type of video imagery is done with only IR light, the image will be in either black and white or monochromatic.  But very seldom will the detail or resolution degrade so the IR video image is as good of quality as the day time color versions.

Security Camera King has a large variety of digital color CCD cameras.  Check our on-line catalog to see all the digital color CCD cameras that we have to offer.
