Home Security Gate Camera

Written By:
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.

Outdoor Exterior Security Camera Software

Written By:
Thursday, December 30th, 2010

In this article we are going to talk about outdoor exterior security camera software. We’ll talk a little about what it is and how it works and what type of outdoor security camera equipment you can use with it.

So exactly what is outdoor exterior security camera software? There are basically two types of software. The first type is software that is used on a standalone digital video security camera system and the second type is software that is used with outdoor exterior security cameras and your personal computer. Although the name “outdoor exterior security camera software” refers to a computer based program, both types serve different roles in a digital video security camera system.

The first type of outdoor exterior security camera software that we refer to is used with a standalone digital video security camera system. These systems normally consist of one to several cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and a monitor. The outdoor exterior cameras capture the video image and send it in digital form to the DVR unit that includes the DSP. The DSP interprets the digital data and uses a special program utility, called a COmpression/DECompression or CODEC to create a digital video file. The digital video file is stored on the DVR and can be viewed on the monitor in real-time (live) or at a later time.

The outdoor exterior security camera software in this case is used on the DVR with the DSP to coordinate each component in the standalone system and provide any additional camera, DVR, or monitor functions. For example, outdoor exterior security camera systems are often used in commercial settings such as providing security in store parking lots. In this example the software coordinates the functions of the cameras with the DVR and DSP, may provide the programming necessary for the CODEC that is used, and directs the DVR to store the digital video file that is created.

In addition, this particular outdoor exterior security camera software may also include special functions that either operate or control the camera, DVR, and monitor. A specific example of this type of software is often used in the store parking lots already mentioned. In this setting, it may be advantageous for the user to follow or “track” a person or vehicle. Pan-Tilt-Zoom (PTZ) cameras used with DVRs that have software with this capability can detect motion. Once the motion is detected (by the software programming) the camera is controlled by the software to Pan, Tilt, or Zoom in order to provide the best possible video of the object as it moves in the field of vision of the camera. Usually, this software is provided by the manufacturer of the DVR at the time of purchase of the unit.

The second type of outdoor exterior security camera software that we mentioned earlier is used with cameras and a personal computer. Although this software may be able to perform the same functions as the standalone security system, it has an additional responsibility of coordinating the digital video cameras with the computer. In these systems the personal computer takes the place of the DVR and DSP as well as the monitor.

These systems are advantageous because they enable the use of an existing personal computer with the digital security cameras. The computer is connected to the cameras via a PCI type computer card that serves as the bridge between the two. Ultimately, for just the cost of the digital video cameras and outdoor exterior security camera software and PCI card, an entire digital video security system can be constructed without the need to purchase a DVR and monitor.

Since computer and electronic technology is rapidly advancing, there may be a third type of outdoor exterior security camera software to consider as well. Although this system uses components that are not specifically designed as digital video security equipment, it may make an economical suitable substitution in some instances. This third type of software allows the use of a webcam or other similar device to be used as a security camera.

This should give you with some good introductory working knowledge about outdoor exterior security camera software. There are as many different brands of software as there are manufacturers of equipment; too many in fact to mention in this article.

Camera Monitor Security Software

Written By:
Tuesday, December 21st, 2010

Using camera monitor security software, you can turn an average webcam into your own digital video security camera. Though digital video security cameras are designed specifically for security and surveillance applications and provide the best option for this purpose, it is possible to use new or existing web cams, digital cameras, and even video cameras for security monitoring.

There are many different camera monitor security software programs available today. In fact, this software is not limited in application to just webcams and similar devices but also applies to the programs that are used on a Digital Video Recorder (DVR) for standalone digital video security systems. Let’s talk about the software that applies to webcams and similar devices first, and then we’ll mention some features of the camera monitor security software used on DVRs.

A typical standalone digital video security system is a component system which consists of at least three major components: 1) One or more digital video cameras; 2) A DVR with a Digital Signal Processor (DSP); and, 3) A monitor.

A digital video security camera converts the reflecting light energy in the camera’s field of view into electrical energy. This electrical energy can be measured and digitized (converted from analog to binary or digital form) and passed along to a DSP. The DSP compiles the data sent to it from the camera and creates a digital video file that is stored on the DVR and/or can be viewed in real-time (live) on a monitor.

Camera monitor security software allows one to use a digital video device not typically designed for security and surveillance applications, to be used for this purpose along with a personal computer. Using this software, the user can program the computer to become the DVR and monitor and link the digital video device to them.

This is not the same as a system that is specifically designed to work with a computer by inserting a PCI card and installing special software to use with the PCI card. An example of such a system is a Geovision system, (see our July 2010 Archive in our Knowledge Base or click this link http://www.securitycameraking.com/securityinfo/2010/07/ for information on Geovision systems). Geovision systems are designed to be used with standard digital video cameras, not webcams.

There advantages and disadvantages to using camera monitor security software instead of a standalone digital video security system. The following lists a few of each:

Advantages
• Allows you to use existing hardware so that only the software needs to be purchased.
• Significantly reduces the cost for a digital video security system.

Disadvantages
• Many programs/computers can only utilize one camera, which is seldom enough to provide comprehensive security coverage.
• Webcams are generally designed for “up-close” usage and may not provide an adequate field of view.
• Most personal digital video devices (webcams, digital cameras, etc.) are not weather-proof and cannot be used outdoors.
• Using this software, especially continuously, can tie up valuable personal computer resources such as memory and hard disk drive space which can significantly reduce the efficiency of the computer for other tasks.

The disadvantages of this specific type of camera monitor security software generally outweighs the advantages for use in security and surveillance applications. Nonetheless, it can provide an economic solution for applications where a computer and webcam are already available.

The other type of camera monitor security software mentioned at the beginning of this article is designed for use with standalone DVR systems. This software is usually a proprietary program that is designed by or for the manufacturer of the DVR. Modern DVR units are basically mini-personal computers but are specifically designed for video recording use. This software coordinates the interaction between the digital video security camera, the DVR, and the monitor.

In addition, the software may contain additional features such as:
• Motion detection;
• E-mail or other electronic communication alerts;
• Timing functions;
• Controlling camera functions such as Pan-Tilt-Zoom (PTZ); and,
• Controlling monitor display functions such as the number of cameras, the frame rate, color or black and white, and other features.

As you can see, in either application, camera monitor security software is the programming link between the various hardware devices including the processor. It can be designed for specific or general applications and can be provided in a variety of different formats.

Security Camera System for Courthouse

Written By:
Thursday, November 4th, 2010

A security camera system for courthouse use can augment other security systems such as metal detectors, guards, and bailiffs. While we tend to think of courthouses as extremely safe and secure facilities, they do have the potential for violent outbreaks. Further, if such a situation should occur, nothing can provide better documentation of the event than a digital video security camera system.

Is it really necessary to have a security camera system for a courthouse? Absolutely; while most courthouses have armed guards and metal detectors for protection, a digital video security camera system can also help deter violence, document criminal events, and protect courthouse employees.

In addition, most courthouse security measures focus on the interior of the courthouse. A digital video security camera system for courthouse use can provide not only interior coverage but just as important, exterior coverage where undesirable events may first begin.

Another advantage of a security camera system for courthouse use is the deterrence of violence and vandalism. It’s a proven fact that digital video security cameras do deter criminal activity. The statistics to support this fact have been shown in both New York City and London, England where police agencies use video security surveillance to monitor day to day street activities. Potential vandals or other criminal perpetrators are less likely to follow through on illegal acts if the know they are being watched and recorded by video cameras.

The occurrence of an unlawful act even in a courthouse requires proper evidence. Nothing can provide documentation for proof and evidence better than a digital video security camera system. A security camera system for courthouse use includes a Digital Video Recorder or DVR. Video images are converted into digital video files and saved on the DVR for later use if necessary. DVRs with CD/DVD writers or thumb drive writers can even provide multiple copies of video footage for distribution to law enforcement agencies, prosecuting attorneys, and other courthouse personnel.

Needless to say, working in a courthouse can be extremely stressful. Since there are always two opposing sides to every issue, there’s bound to be unhappy, tense, and impatient people that must interact with other courthouse employees. Unfortunately, there are isolated incidences where these emotions run rampant resulting in outbursts against courthouse employees. A security camera system for courthouse use can not only spot incidents when they begin and document them as they occur, but help deter them from occurring in the onset.

Another benefit of digital video security camera systems is remote control and monitoring of the system. Thanks to advancements in computer and electronic technology, a security camera system for courthouse use can be remote controlled from just about any other off-site location that has a broadband Internet connection. Authorized users can monitor and record Internet Protocol (IP) ready cameras in a totally different physical location than the system. This feature can be particularly beneficial in the unfortunate event of bomb threats, taking of hostages, and other acts.

The use of Pan-Tilt-Zoom (PTZ) cameras, especially in courthouse parking lots, can provide an early warning of an event before it reaches the inside of the building. Furthermore, DVRs with object tracking can detect motion and automatically pan, tilt, or zoom the camera to track or follow a vehicle or individual.

Maintaining the ultimate security of a courthouse is tantamount to maintaining justice. The very nature of the events that occur within a courthouse and the fact that individuals suspected of murder, manslaughter, and other violent crimes are brought to a courthouse for trial indicates the necessity for proven security measures.

A properly designed and installed security camera system for courthouse use will provide images of all individuals that enter and exit the building. Public areas within the courthouse can be monitored by video security cameras, freeing courthouse guards to provide their services where they are needed the most.

Wireless 16 Camera Motion Detector Security Surveillance

Written By:
Tuesday, October 12th, 2010

Wireless 16 camera motion detector security systems are capable of providing total video security for any residence or business. These systems make installation a cinch and in addition conserve on system resources. In addition, these systems are incredibly versatile, especially when utilizing optional features.

Generally, the brain or heart of a video security system is the Digital Video Recorder or DVR. The DVR normally contains a specialized computer processor that is designed to perform the tasks necessary to create and store digital video files and coordinate and control digital video camera functions. For a wireless 16 camera motion detector security system only one DVR is required, although it is possible to create 16 camera systems using a variety of DVRs with lower camera input capacities (such as two 8-camera DVRs).

Since “wired” camera security systems must have a coaxial video transmission cable run from each camera to the DVR the only determining factor for the number of cameras used in the system is the number of video inputs that can be handled by a DVR (Usually 16 is the maximum. Systems requiring more video inputs than 16 usually utilize more than one DVR.)

However, the single most determining factor for a 16 camera motion detector security system is how the cameras’ wireless video signals are handled. Each camera must have its own unique frequency or channel on which to transmit its digital video signal. It’s important to pause here for a minute to discuss the use of the term “channel” as there is some ambiguity involved with the use of the term in the realm of video security.

Most of us would probably think of a channel as a specific frequency, such as a television channel or radio station channel which is one way the term is used in the industry. For example, a wireless camera may transmit on 921.103102 MHz which, for the sake of this discussion, we will call channel 1 or 921.205012 which we may call channel 2. That’s one security camera industry definition for “channel.”

However, often times “channel” is used to reference the number of video and/or audio inputs a DVR or receiver can utilize. In this instance a 9 channel DVR would be able to accept inputs from up to 9 different video cameras also called “channels.” For example the most common DVR units are four, eight, and sixteen channels.

Getting back to our discussion of wireless 16 camera motion detector security systems, these systems would normally require a 16 channel (camera input) DVR. They would also require 16 wireless cameras each on a different channel (frequency). The key factor for these systems would be:
1. Acquiring 16 cameras each transmitting on a different frequency; and,
2. Determining how to receive these signals.

This could be done in a variety of ways ranging from using multiples of receivers that total a video output to the DVR of a total of 16 individual video channels, or using multiples of DVRs that total 16 individual video channels or inputs with each camera input using a different frequency (also referred to as a channel). In addition, modern technological advances have produced IP or Internet Protocol ready cameras that contain their own web server technology. Sixteen of these cameras could theoretically be used to create a wireless 16 camera motion detector security system as well.

In these systems, each of these cameras have a built in PIR or Passive InfraRed sensor. These sensors can detect a change in infrared transmission, such as that caused by a moving object. The PIR sensors are normally connected to a relay that switches the camera video transmission on when motion is detected. The camera stops recording either after a predetermined programmed time period or when the motion detection ceases.

A motion detector operated camera offers several potential benefits that include:
• Conservation of DVR disk space since video is only transmitted when motion is detected;
• Conservation of power usage which is especially important if the cameras operate on battery power; and,
• An alerting function since the cameras only record if motion is detected (For example, some IP ready cameras or DVRs can send an email when the camera has been triggered “on.”)

In addition, wireless 16 camera motion detector security systems may be purchased with optional features such as day/night, Pan-Tilt-Zoom (PTZ), object tracking and many other options, all of which contribute to making these systems one of the most versatile video camera security solutions available today.
