Home Security Gate Camera

Tuesday, January 4th, 2011

A home security gate camera can alert to you to approaching visitors long before they reach your door, prevent unwanted and unnecessary solicitors and assist in providing gate access control.

Home owners often start their residential digital video camera security system with a single home security gate camera. However, after using this camera for a while and realizing the potential security and monitoring power of a digital video camera, they usually return to purchase an entire digital video security system for the house and residential property. This is easy to do as there are systems that easily support up to four, eight, or even sixteen individual cameras.

A home security gate camera used in tandem with a remote electronic gate lock and opener can provide you with security guard “like” control of your property’s entrance. This can be accomplished by using a digital video security camera with audio capturing technology (or an intercom) and either a wired or wireless electric gate lock and opener.

When a visitor arrives at the gate entrance, the user can look at the security system monitor to see the individual’s face and/or the vehicle they are driving. Once the home owner has identified the visitor, they can press the remote gate lock and opener button to allow the individual to enter the property.

For individuals with large homes on abundant land and long driveways, this feature is particularly useful for controlling access to the residence. Some may want to modify the system a bit and use a two-way intercom so that a conversation can take place between the user and a visitor if need be.

There are some features available that you may want to consider before purchasing your home security gate camera. First and foremost, the camera must be an outdoor type camera. These cameras are specifically made with an enclosure or case that provides protection from the weather and elements. These cameras often utilize the International Electrotechnical Commission’s Ingress Protection or International Protection (IP) code.

The IP code consists of two digits, with the first digit representing protection from solids and the second digit representing protection from liquids; the higher the number of each digit the better the protection. The ranges of digits are 0-6 for the first digit and 0-8 for the second digit. An outdoor camera with a rating of IP55 or greater should work fine.

If you want a camera that can capture images ’round the clock (24/7), you may want to consider providing flood lighting at the gate for night time monitoring. However, a cheaper and much easier alternative is to use a home security gate camera that has infrared night vision.

Night vision infrared cameras work both in daylight and in darkness. The camera is sensitive to near infrared spectrum radiation “light.” The infrared light is provided by on-board infrared producing Light Emitting Diodes or LEDs. These LEDs are normally arranged in an array around the camera lens so that they provide a floodlight of infrared illumination in the camera’s field of view. This light is invisible to the human eye, but visible to the camera.

If you are interested in monitoring more area than just the gate or visitor, you may also want to consider a Pan-Tilt-Zoom (PTZ) camera. These cameras can be remotely controlled by the homeowner to move horizontally or vertically to increase the camera’s field of view. Images can be enlarged by using the zoom function. Many DVRs (Digital Video Recorders) have programming that can automatically control PTZ cameras to track or follow objects.

Whether you have the security system installed by a professional or are installing it yourself, you may also want to consider a wireless, battery operated camera. Digital video cameras require that an RG-59 type coaxial video transmission cable be run from each camera to the DVR unit (or monitor if no DVR is used). In addition, each camera needs a low-voltage DC wire run to it for a power supply. A wireless, battery operated camera eliminates the need for any cabling and makes installation a snap.

There are a lot of choices for someone looking to purchase a home security gate camera. Today’s technological advancements have yielded a large variety of optional features that have made home security gate cameras even more powerful, providing the protection you need.


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.


Heavy Duty CCTV Cameras

Thursday, December 9th, 2010

There are times when a situation calls for something more rugged than standard Closed Circuit Television (CCTV) cameras and that is when it’s time to consider heavy duty CCTV cameras. Heavy duty CCTV cameras are built tough to withstand use and abuse and still keep working.

A standard digital video color security camera has no moving parts unless it contains additional features such as Pan-Tilt-Zoom (PTZ). The PTZ function works by using servos or motors to move the position of the camera up and down or left and right to increase the camera’s field of view. Zooming involves moving the lenses in such a way as to enlarge the size of the target.

Most heavy duty CCTV cameras have these movements reinforced in some manner so that they do not become a factor in making the camera more susceptible to damage. Since the average camera has no moving parts per se, that contributes greatly to making the camera inherently rugged.

In order to understand this concept of no moving parts, the following is a brief description of how the typical digital video camera works. Light images enter the camera through the lens. If the lens is a fixed focal length lens (i.e. not a zoom lens) there is no need for it to move. As the light passes through the lens, the lens focuses the image on an electronic sensor that usually ranges in size from 1/4 to 1 inch square.

The sensor is an electronic component that can change light energy into electrical energy that can be measured. The electrical energy is compiled into a signal which passes through an analog to digital circuit that converts the signal into binary or digital format. The digital information is then sent to a Digital Video Recorder or DVR via a digital video transmission cable or, if the camera is wireless, as a radio signal to a corresponding receiver.

Note that none of these processes involve moving, mechanical type parts. The lack of moving parts is one less factor that could contribute to the “sensitivity” of a heavy duty CCTV camera. Not that a camera with moving mechanical parts can’t be used as a heavy duty CCTV camera, it’s just that this is one additional advantage of the construction of these cameras.

By comparison, think of a typical camcorder that records its video image to a tape, DVD, or a hard drive. Drop that camera one time on a hard surface with some respectable force and chances are you’ll be sending it in for repair or replacement, and chances are the moving mechanical parts are what break.

So what kind of heavy duty CCTV cameras are available? Generally, security and surveillance applications can be classified into two types, indoor and outdoor. Indoor cameras are made with no additional protection from water, wind, hail, etc, as they are designed to be used indoors, under the protective cover of a room.

Outdoor cameras are one type of heavy duty CCTV cameras that are designed specifically for the purpose of being used outside without the protective cover of a room, roof, or building. These cameras differ from indoor cameras in that they are contained within a protective enclosure. Normally, the enclosure is a heavy duty metal box or molded Plexiglas or Lexan.

Heavy duty CCTV cameras for outdoor use are often rated by the manufacturer as to their ability to protect the camera from foreign objects. One common standard that is used is called the International Electrotechnical Commission’s (IEC) Ingress Protection rating or code also called an IP code or rating. The IP code consists of two digits; the first digit represents the degree of protection from solid objects and the second digit represents the degree of protection from liquids.

The first digit of the IP rating (solids) ranges from 0 to 6, where 0 represents no protection and 6 represents absolutely no penetration from dust or other large objects. The second digit ranges from 0 to 8 where 0 represents no protection and 8 means the camera is protected from liquids to the extent that it can be submersed in water beyond 1 meter in depth. The highest IP rating is IP68.

There is also a wide variety of specific use heavy duty CCTV cameras. These cameras may be manufactured in such a way that they are marketed as vandal proof or even explosion proof. These cameras may use special mounts designed specifically for that purpose.


Outdoor Motion Activated Security Surveillance System

Thursday, November 4th, 2010

An outdoor motion activated security surveillance system is an excellent tool to provide security and surveillance for almost any residential or commercial application. Modern technological advancements have made this surveillance system incredibly versatile and reasonable priced as well.

An outdoor motion activated security surveillance system’s cameras are specifically designed for outdoor use. These cameras (as opposed to indoor cameras for example) are designed to be housed by a protective enclosure. The enclosure protects the camera from weather, dust, and other objects.

An outdoor security camera may be rated according to the protection that is afforded to it by the enclosure or its casing. This rating, an Electrotechnical International Commission (EIC) standard, is call an Ingress Protection rating, IP rating, or IP code.

The rating consists of the letters “IP” followed by two digits, for example IP65. The first digit of the rating describes the extent the camera is protected from solid objects and the second digit indicates the extent the camera is protected from liquids. The example IP65 rating means the camera is dust free and protected from water sprayed from nozzles in any direction.

The first digit of an IP rating for an outdoor motion activated security camera system ranges from 0 – 6 with 0 indicating that there is no protection against contact or ingress of objects. As the number increases from 0 to 6, the rating indicates that the camera is protected from objects continually smaller in size. A first digit IP rating of 6 indicates no dust and complete protection against contact.

The second digit of an IP rating for the camera ranges from 0 to 8 with 0 indicating that there is no protection from water. As this digit increases in value the rating indicates progressive protection from water with 1 meaning protection from dripping water and 8 meaning continuous immersion in water.

An outdoor motion activated security camera system also has a unique characteristic as indicated by its descriptive name. The cameras only record video when motion is detected.

This is accomplished by an on-board Passive InfraRed (PIR) sensor. The PIR sensor can detect the infrared radiation from objects in the camera’s field of view. If the sensor detects a significant change in the infrared radiation in this view, it assumes it is created by a moving object; hence it detects “motion.” The sensor is connected to a relay that turns the camera on in recording mode to capture the video images. The camera shuts off or stops recording when the sensor detects that the motion has stopped or after a pre-programmed period of time.

This feature, though small and simple in design and appearance, can offer tremendous benefits in the functioning of a security camera system. Since the camera will only record video when motion is detected, this can save a tremendous amount of file space use on the system’s Digital Video Recorder or DVR.

Since the DVR records video images in sequence, it will continue recording until the DVR’s storage capacity is full. Once the DVR is full however, the video image files are rewritten over the files that are the oldest, continuing this process until the DVR is full and then repeating the process over and over again. A motion detector activated camera can extend DVR recording times before repeating and rewriting, significantly.

In addition, a motion activated security camera system camera must have a power supply. This may be in the form of a small, low-voltage Direct Current (DC) power line run from a power distribution center to each camera or from a nearby plug-in transformer. Many cameras have the ability to operate on the power supplied by batteries, either one time use types or rechargeable types.

The PIR sensor on a motion activated security camera uses a very small amount of power to stay on. In fact, compared to the power required to capture video, the PIR sensor’s power usage is significantly lower. Motion activated cameras that operate on battery power last significantly longer between charges or battery changing because the motion sensor, in effect, conserves battery power.

There are many additional/optional features that contribute to the versatility of an outdoor motion activated security camera system. Some of these features include:
• Pan-Tilt-Zoom (PTZ) functions
• Day/Night vision
• Night vision infrared recording
• Wireless cameras
• IP ready cameras and/or DVRs

These features coupled with the motion activated feature make the outdoor motion activated security camera system appropriate for almost any commercial or residential application.


Outdoor Wireless Security Camera 500ft Range

Monday, October 18th, 2010

An outdoor wireless security camera 500 ft range is adequate for most commercial and residential applications. This type of camera is easy to install and easy to operate and can be purchased with many optional features that greatly increase its versatility. In the following article we’ll talk a little about wireless security camera technology and some of the additional features that can be purchased for these cameras.

There are a few key factors that separates an outdoor wireless security camera 500ft range from other basic security cameras. First, as its name denotes, this camera is an outdoor camera. Outdoor security cameras are designed to withstand weather and other natural outdoor elements that can damage the camera or affect the working quality of the cameras.

When a security camera is specifically classed as an “outdoor” camera, it often has a rating in the camera specifications that indicates exactly how much protection is afforded to the camera from external objects. This rating, called an Ingress Protection rating or IP code, is an International Electrotechnical Commission (IEC) standard.

The code consists of the capital letters “IP” and two digits. The first digit indicates protection afforded against solids and the second digit indicates the protection afforded against liquids. The first digit’s scale ranges from 0-6 with 6 being the best protection, and the second digit’s scale ranges from 0-8 with 8 being the best protection. A good IP rating is IP65 or IP66.

IP65 means the camera is completely protected from dust and water jets from a nozzle coming from any direction. IP66 means the camera is completely protected from dust and water projected by powerful nets in any direction.

The other key feature of an outdoor wireless security camera 500ft range is that the camera uses wireless technology and has a maximum operating range of 500 feet. Non-wireless digital video security cameras work by creating a digital picture and transmitting the digital video data to a Digital Video Recorder (DVR) or monitor via a coaxial video transmission cable. This cable, usually an RG-59 coaxial cable must be run from each individual camera to the DVR or monitor. Wireless cameras eliminate this video transmission wire.

Outdoor wireless security cameras with a 500 foot range contain the internal circuitry to convert the digital data into a radio waveform that can be sent with out cabling. There are various radio technologies used to do this based on the manufacturer, but some of the more popular are the 900MHz an 2.4 or 5.8 GHz band radio technologies. These are the same sorts of technologies used by land line based wireless telephones.

One word about the camera radio technology. This technology is usually based on range which is defined as the maximum distance between the camera antenna and the receiver (or DVR) antenna based on Line Of Sight or LOS. LOS means this range should be attainable provided there is a clear line of sight between the two antennae, i.e. no objects can impede or block the LOS.

If there is not a clear LOS, it doesn’t mean the camera will not work. Usually, depending on the object(s) such as glass, trees, or walls instead of the camera signal failing, the range is just reduced. How much the camera’s signal is reduced is dependent on the material that the signal must penetrate. For example, it is not uncommon for an outdoor wireless security camera 500 ft range LOS to work at a 200 – 400 foot range through walls.

Digital video security cameras are powered by low voltage Direct Current (DC) electricity. This may occur as a small wire that is run from a power distribution center or a plug-in adapter that can be plugged into the nearest wall outlet. Since wireless cameras have already eliminated the need for a video transmission cable, some manufacturers make models that are totally wireless’ the camera can run off of power from batteries or rechargeable batteries.

There are many cameras with optional features that can be purchased. A few of these features include:
• Audio Recording
• Infrared Night Vision
• Day/night low visible light operation
• Pan-Tilt-Zoom (PTZ) operation
• IP or Internet Protocol ready

This should give you enough working knowledge to help you decide if you need an outdoor wireless security camera 500 ft range. If you have any other questions or would like to make a purchase, contact one our Security Camera King’s security experts today.
