Why Does My Company Need Parking Lot Security Cameras?

Parking Lot Security CamerasParking lots and parking garages are appealing for criminals because they provide a source for a wide variety of criminal activity. Car thieves see hundreds or even thousands of opportunities for potential hits in parking lots and parking garages. Other thieves also see parking lots as a gold mine — countless stereo systems, speakers, GPS systems, laptops, cell phones and other personal property are available for taking. Customers are not the only ones at risk. Your company’s shopping carts, outdoor landscaping and even plants and shubbery are also at risk of being stolen in a parking lot with no security cameras.

Not only is a parking lot a potential feeding ground for thieves, but an unsafe parking lot can also be a dangerous place for your customers and employees. People with bad intentions have a lot of opportunities to hide and prey on unsuspecting victims in parkings lots; countless muggings, kidnappings, murders and rapes have occurred in unsafe parking lots and parking garages.

A perhaps less dangerous, but still pesky and expensive problem that often plagues parking lots and parking garages is vandalism. Teenagers and other mischief seekers may find an un-secure parking lot as a great opportunity to vandalize both vehicles and your company’s property.

Although crime can and does happen anywhere, parking lots are particularly attractive to criminals because of their size and the volume of people and vehicles there. These crimes can be greatly reduced with proper security measures. Parking lot security cameras and surveillance cameras, as well as many other security precautions have proven to help prevent criminal activity in parkings lots and parking garages. Just the sight of security cameras and posted surveillance signs are often enough to stop a tempted criminal dead in his tracks. In the event that a crime does occur, proper parking lot security cameras can aid in the arrest and conviction of the criminal and can serve as a lesson for others who are contemplating committing crimes in your parking lot. They say that a picture is worth a thousand words, but a full-color video is worth even more than that in police stations and court rooms.

In addition to preventing crime and convicting criminals, parking lot security cameras also add a sense of safety and security that will make your employees and customers feel more at ease. Customers who see ample surveillance cameras and other security equipment in a parking lot immediately feel safer, and feel that their vehicle and belongings are safer. A safe parking lot can make your business more attractive than other area businesses that do not have proper parking lot security cameras and other security devices, therefore increasing business and giving your company a better image.

What Security Measures Should I Take In My Parking Lot?

When installing parking lot security cameras and surveillance cameras, there are a few things to keep in mind. Each company’s parking lot or parking garage is different and has different security needs; although all parking lots should have a certain level of security, some parking lots and parking garages require tighter security than others.

A small parking lot in a safe area may only require a few security cameras and a couple of posted signs. Larger parking lots and parking garages require an extensive system of parking lot security cameras, along with other security measures, to ensure maximum safety and security.

Proper lighting is a must for all parking lots and parking garages. Customers who can see clearly as they walk to or from their vehicle, even in the dead of night, will feel much safer and more secure. Bright lighting makes it much more difficult for potential criminals and mischief seekers to do their deeds without being seen. Ample lighting also helps to deter thieves and vandals. A darkly dressed criminal may feel he can beat the security cameras without being recognized in a dark area, but he will often be far too intimidated and afraid of being seen if there is bright lighting in the parking lot.

In dangerous neighborhoods or high crime areas, having gates around your parking lot and having security guards might be a good precaution to take. Although this is often un-neccessary with proper parking lot security cameras and lighting in a safe neighborhood, if your area is subject to a high crime rate or if your security cameras aren’t doing a sufficient job preventing crime, hiring a few security guards may be a good idea. In most cases, however, hiring security guards can be an expensive and unnecessary precaution if you have adequate lighting and the proper amount of surveillance cameras.

On top of these security precautions, parking lot security cameras are arguably the most important aspect of parking lot security. Make sure that security cameras are installed at any entrances and exits so that you have a clear view of every vehicle that enters your parking lot. Strategically place security cameras so that every inch of your parking lot can be seen on camera. Now is not a time to be cheap — be sure to invest in enough security cameras that your parking lot is fully covered.

After installing your parking lot security cameras, be sure to post multiple signs letting everyone know that they are there. Someone who is too quick to look for hidden cameras will often notice posted signs and will realize that their actions are being taped, causing criminals to rethink their actions. Posted signs also inform your customers and employees of the security cameras in your parking lot, so that they can feel safer and more secure.

Along with using signs to inform your customers and employees of this change, be sure to inform your insurance company about your recent parking lot security camera installation as well. Some insurance companies actually offer reduced rates and discounts for companies that use parking lot security cameras, yet another reason why installing surveillance cameras is a good idea. Also, in the unfortunate event of a liability case against your business, proof of sufficient parking lot security can help you to establish non-negligence.

What Kind Of Security Camera is Best For Parking Lots?

Obviously, there are many security cameras available on the market, and not all of them are ideal for parking lots and parking garages. A security camera that is designed for outdoor use is a must for parking lots, as it must be sturdy enough to make it through rain, wind, snow and other inclement weather. As security cameras themselves are often targeted by thieves and vandals, you should also take precaution to protect your cameras. Installing them on light posts and other tall fixtures is an effective way to protect your security cameras from the wrong hands. Vandal proof security cameras are also available on the market. Vandal proof security cameras are designed so that they are difficult if not close to impossible to break or steal.

Some security cameras have extra features and can zoom in or out, move from side to side and more. Some security cameras use infrared technology or are designed to be day/night cameras, providing a perfect picture even on the darkest of nights. There are even security cameras that are equipped with a motion sensor and can be programmed to zoom in and follow the movements of an individual or vehicle.

If wires are a concern, there are many security cameras that are wireless. Some only use a small power supply line, but others are completely wireless due to the use of rechargeable batteries. No matter what your parking lot needs or what concerns you have, feel rest assured that there are security cameras on the market for you.

In many cases, using a combination of different kinds of parking lot security cameras can prove to be effective. Several regular outdoor-use security cameras, combined with a few night-vision cameras and a few security cameras with motion detection technology can combine to be an effective combination when monitoring parking lots.

How Should I Monitor My Parking Lot Security Cameras?

Your parking lot security cameras will be hooked up to a main security system. In some cases, this system may be your PC, but most security parking lot security camerassystems have their own stand-alone digital video recording unit. A digital video recorder records the footage from your parking lot security cameras as a digital file to be watched at your discretion. These digital video recorders, or DVRs, are useful and convenient because they allow you to pause, rewind and fast forward through the footage, just as you can with your home television DVR. Different DVR systems have different storage capacities and it is ideal to choose one that allows you to save footage for a significant amount of time. Footage that doesn’t seem important right now could turn out to be just the tape that you need in a few months.

It is a good idea to put your monitor in an office or other area that is restricted from the public. Keeping it in an office where you or other employees get a lot of work done is sometimes a good idea, because then you can keep an eye on the running footage and possibly notice if something seems amiss in your parking lot. Periodically watch your security footage, even if nothing has been reported. This can sometimes help you to solve problems before they actually occur; if you notice an individual who is behaving suspiciously, you know to keep your eye out.

Never disconnect or turn off your security cameras; it’s inevitable that the one time that you do will be the time that something goes wrong. Keep your parking lot security cameras in good working condition and you will never regret your decision to have them installed.


Infrared Wireless Camera

Wednesday, June 15th, 2011

You may be wondering what an infrared wireless camera is.  It is a digital video camera that can capture digital video images in total darkness and does not require a coaxial video transmission cable run from the camera to the Digital Video Recorder or DVR.

Let’s start at the beginning.   A digital video security and surveillance system normally has three basic parts or components:  The camera(s); the DVR; and, the monitor(s).  It’s the camera that we are interested in so lets talk about how it works and what it does.

Unlike the infrared wireless cameras, most cameras need some sort of connection wire to send their video data over to the DVR.  Most often, this wire is actually RG-59 coaxial cable.  The signal originates at the camera end and terminates at the DVR end.  There is nothing wrong with this method; in fact this is the way most security systems are set up.  However, if you want to avoid running all that cable, then you may want to consider a wireless camera.

The wireless camera helps to avoid all the time and effort it takes to run the RG-59 cable.  Imagine that you want to install a gate camera at the end of a very long driveway.  Can you imagine the cable run through your house all the way out to that camera at the gate?

On the other hand an infrared wireless camera has its own on-board transmitter and built-in antenna so that it can send the video data to the DVR in radio frequency format instead of cable.  Actually the camera sends the radio transmission to a corresponding receiver made specifically for this purpose.  The receiver is then connected to the DVR by a coaxial cable and relays the camera’s signal to the DVR via this short cable.

The camera at this point is not truly 100% wireless.  All cameras must have some sort of power supply and so a power supply line must be run to the camera.  In this situation, this can still be a bit of an advantage at making installation easy because a single plug-in type transformer, made specifically for the camera can be plugged in to an outlet nearest the camera reducing the power supplies’ cabling run.

A truly infrared wireless camera can be achieved with very little effort.  This is probably the most desirable configuration because there are absolutely no wires or cables that need to be run from the DVR to the camera.  There are many infrared wireless cameras available from Security Camera King that obtain their power supply from on board batteries.  This makes the camera truly wireless.

When purchasing a wireless camera, make sure you know how far (usually in feet) that your camera will be separated from the receiver.  Most cameras employ a wireless transmission type where the maximum range is stated based on Line Of Sight or LOS.  That means that a camera with a wireless range of 300 feet has that range based on LOS.  If there are any objects between the receiver and the camera you could loose the signal entirely, although this is rare.  Generally, depending on the amount and material the radio signal must go through it simply reduces the camera’s range.

The other half of the infrared wireless camera, that is the infrared portion, allows the camera to see in total darkness.  The camera lens focuses the field of view onto a small (usually 1/4 to 1/3 inch square) sensor that when struck by light energy emits electrical impulses that can be measured and used to create an electronic reproduction, or video footage.

The chips that are used are the Charged Coupled Device (CCD) and the Complementary Metal Oxide Semiconductor (CMOS).  Both the CCD and the CMOS have the inherent ability to react not only to the visible light spectrum but they can also see the near red infrared light spectrum (human eyes cannot see this type of infrared radiation–simply put it is invisible to us).

An infrared wireless camera is usually supplemented with an array of InfraRed Light Emitting Diodes (IR LEDs) positioned around the lens.  This is like using a floodlight on a non-infrared camera.  Additional illuminators can be purchased to extend the distance of the camera.

An infrared wireless camera not only has a transmission range, but it also has an Infrared range distance.  Make sure to check the infrared range on the camera before purchasing it as well.


Wireless Wall Clock Camera

Tuesday, February 15th, 2011

Sometimes it’s necessary to keep a watchful eye covertly, and a wireless wall clock camera is just the device for the job. Security Camera King offers several different types of hidden cameras, including wireless wall clock cameras. These cameras are built in such a way that detection of surveillance is almost impossible.

Our security experts are often asked how these cameras actually work and how they can be concealed in an object like a clock. In the following article we’ll talk about how a wireless wall clock camera works an mention the types available for purchase through Security Camera King.

The key factor behind hidden or disguised digital video security cameras is advanced technology. In the no to distant past, security and surveillance cameras were analog based. Since they are now digital, that has allowed the security camera industry to share the benefits of technological advances found in the personal computer and electronic industries. This in turn has yielded incredibly small, high quality cameras that can capture video images in a variety of different conditions.

Creating a digital video image using a wireless wall clock camera begins with the camera’s lens. Objects have a natural tendency to reflect light. The light that is reflected is gathered by the lens and focused on an electronic sensor. Many hidden cameras use a highly accurate 3.7 mm wide angle lens. To get an appreciation for the size of this lens, hold two nickels together. The thickness of two stacked nickels is a little greater than the entire size of a 3.7 mm lens. The wide angle feature allows this small lens to have a proportionately larger field of view.

The lens focuses the light image on a small electronic sensor. One of two different sensors is used. A Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor or CMOS converts the light energy into electrical impulses. The CCD and CMOS go about the process a little differently, but both yield the same end result; electrical impulses that can be measured and used to create a digital video image.

As a side note, CCDs have historically produced a higher quality image with a greater demand for electrical power while CMOSs have produced a slightly lesser quality image with a lesser demand for power. However, as technology advances, both CCDs and CMOSs are approaching an equal state of quality and power demand.

All of Security Camera King’s wireless wall clock cameras use CCDs. One would think that the electronic sensor would need to be rather large, especially when using a wide angle lens. However, our wireless wall clock cameras use a very small 1/4 or 1/3 inch CCD. Using a 3.7 mm lens and such a small CCD, it should become obvious how easy it is to disguise the camera with the clock face.

After the light images are created into measurable electrical impulses by the CCD, the camera then converts this analog data to binary or digital form by using an analog-to-digital converter. The analog-to-digital converter resides in a very small Integrated Circuit or IC chip that takes up very little space.

Now the video data is ready for transmitting. Once again a relatively small IC chip comprises the transmitter. The circuit converts the digital data into radio waves that can be sent by the transmitter to a corresponding wireless receiver.

Our wireless wall clock cameras use 2.4 GHz radio technology; the same technology used by many land-line based wireless phones. This technology offers a strong, clear signal with very little interference.

Normally the receiver is located near the Digital Video Recorder or DVR unit and is connected to it by a cable. Once the wireless wall clock camera video signal reaches the receiver, it is transferred to the DVR where it can be displayed on a monitor and viewed live and/or stored on the DVR’s hard disk drive for archiving or later use.

Security Camera King offers four different wireless wall clock cameras. We offer a “standard” looking wall clock that looks like any plain circular wall clock found in an office or home. We also offer a more sophisticated looking clock camera with humidity and temperature indicators. Each of the two designs offers either a black and white video image or a color video image. The black and white video images models will produce a high quality image in very low light conditions (0.003 lux for example). Check our “Wireless Hidden Cameras” web page.


Wireless IP Security Camera

Tuesday, January 25th, 2011

One of the more recent digital video security camera system components is the wireless IP security camera. These cameras use the Internet as a network medium for the purpose of transmitting their digital video images and for allowing the user to control the camera remotely. This places the maximum power of remote accessibility as well as easy installation in the hands of the user.

It seems as if all of our electronic devices today utilize or have some sort of affiliation with, the Internet. So why shouldn’t the digital video security industry take advantage of its seemingly ubiquitous presence and cost-efficient use as well? That’s exactly what a wireless IP (Internet Protocol ready) security camera does.

By using a wireless IP security camera you can monitor your business in Ft. Lauderdale while on vacation in Tokyo. If you have a Pan-Tilt-Zoom or PTZ wireless IP security camera you can even control the camera from Tokyo moving the camera horizontally, vertically, or even zooming in on an object. You can do all this anywhere there is a broadband Internet connection and an available desktop or laptop computer and even using a 3G or 4G smartphone.

How is this possible? In the following article we’ll discuss what’s inside a wireless IP security camera and how it works, especially with the internet.

A wireless IP security camera differs from a typical digital video camera in several ways. First, a standard digital video security camera is connected to a processing and storage unit called a Digital Video Recorder or DVR. The camera is normally connected to the unit by running an RG-59 coaxial video transmission cable from each camera to the DVR. The camera transmits its video data over the cable to the DVR where it is compiled into a digital video file that is stored on a hard disk drive and may be viewed live on a digital camera security monitor at the same time.

On the other hand, a wireless IP security camera doesn’t use an RG-59 coaxial video transmission cable or any other video transmission cable. This camera has a built-in transmitter that sends its signal using IEEE802.11 or WiFi radio technology. The camera may or may not, depending on the type, also process the video data into a digital video file before being transmitted from the camera. In addition, when the signal leaves a wireless IP security camera it may be sent to an IP ready DVR over the internet, or it can be sent to any other receiving device (such as a computer or smartphone).

A wireless IP security camera also has its own built in web server technology. This allows one camera to capture video, create digital video files, and send them (using streaming technology) over the Internet to a variety of devices already mentioned. Accessing the camera is as easy as opening a standard web browser on your computer and entering the camera’s Internet address and a password. Even smartphones and similar devices such as iPhone, iPod Touch, iPad, Android, Symbian, and Windows mobile phones can remotely view and control the camera as well.

It’s important to note that a wireless IP security camera and an IP DVR system are different. The IP security camera makes a direct connection to the Internet via a wireless broadband modem or router. An IP DVR system on the other hand uses various wireless technologies to connect the cameras to the DVR FIRST. The DVR is than connected to the Internet via a variety of broadband Internet connections.

Note: For IP DVRs smartphones will require an application (app). For the iPhone and similar devices the application is available for free from the iPhone App Store on your phone. For all other types, Security Camera King offers the app for free when you download it from their website. As an additional note, please remember that the app only works with Security Camera Kings Elite Mini, Elite, and Ultimate DVRs with HDMI output. It will not work with any other type of DVR or any of Security Camera Kings DVRs.

Ultimately then, a wireless IP security camera can use the Internet to send digital video images to a variety of computers and smartphones or it can utilize the Internet as a network medium to connect several cameras to an IP ready DVR.

Wireless Camera Outdoor Security Systems

Monday, December 27th, 2010

If you are looking for an excellent method to provide outdoor security and surveillance, consider using wireless camera outdoor security systems. Not only do these systems provide excellent security, but wireless camera outdoor security systems are a snap to install. They make for an easy do-it-yourself installation project with the most difficult task being what type of camera to purchase.

Wireless camera outdoor security systems are component systems consisting of the wireless outdoor cameras, a Digital Video Recorder (DVR), and an optional monitor. Not all of the components are placed outside, in fact usually only the cameras are located outside with the DVR and monitor located nearby indoors.

The system works by capturing high-quality color video images with the digital wireless outdoor cameras. The video images, in the form of electronic signals, are converted from analog signals to binary or digital signals and sent to the DVR. The DVR and video processor converts the information into a digital video file that can be viewed in real-time (live) and/or saved on the DVR for later use.

The wireless camera outdoor security system cameras have two of many additional features that make the system unique. First, the cameras are outdoor cameras, designed specifically for use in places that do not provide shelter or protection from the weather and other elements. Second, the cameras send their video signals via wireless radio waves instead of video transmission cables. Let’s take a closer look at each of these features.

Today’s digital security camera is a relatively small, light-weight piece of modern technology, especially when compared to cameras that were used 20 years ago. However, even though modern technology has yielded great improvements and additional features, the cameras are still designed to be used indoors, under protective cover of a building for example. However, wireless camera outdoor security systems cameras are designed for use outdoors.

Outdoor cameras contain digital video cameras that have a protective case or closure that prevents damage to the camera from the weather and other elements such as rain, snow, and dust. Many outdoor security camera manufacturers provide a rating as to the protection that is provided by the enclosure. This rating called and Ingress Protection or International Protection Code (IP Code) is a standard that is developed by the International Electrotechnical Commission (EIC). The purpose of the rating is to provide a more specific, standardized description of the protection instead of a generalized description such as “waterproof.”

The IP Code consists of two digits and is normally expressed like this: IP37. The first digit refers to protection from solid objects and ranges from 0 to 6 with 0 meaning no protection and 6 indicating the camera is dust tight and completely protected from damage from dust. Digits 1 through 5 indicate protection from increasingly smaller solids. A 5 indicates that ingress of dust may occur, but not in a quantity enough to damage the camera.

The second digit refers to protection provided from liquids and ranges from 0 to 8, with 0 indicating no protection and 8 meaning that the camera can be submerged continuously in water deeper than 1 meter. Typical ratings for wireless camera outdoor security systems are a 5 (no harmful effects from water projected by a nozzle) or a 6 (no harmful effects from water projected by a powerful jet). Examples of good IP ratings for an outdoor camera is IP55 or greater.

The second unique feature of wireless camera outdoor security systems is the wireless function of the camera. Normally, digital video cameras send their video data via coaxial cables such as RG-59. A cable must be run from each individual camera to the DVR. However, wireless cameras convert their data into radio signals and send the data to the DVR as a radio wave.

There are several radio wave technologies used today but one of the more common is the 2.4 or 5.8 GHz technology, the same that is used for land-line based wireless telephones. The camera sends out the signal using its own transmitter and antenna to a corresponding receiver. The receiver is usually located near the DVR and is connected to it by a cable. Some DVRs even contain their own receiver technology, eliminating the need for a separate receiver unit.

Installation of wireless camera outdoor security systems is easy and mainly consists of mounting the cameras and setting up the DVR and/or receiver. For more information, contact one of Security Camera Kings security experts today.
