Church Security Systems

Wednesday, June 30th, 2010

Unfortunately, in this day and age even church security systems are becoming a necessity. Many churches only have people inside or on the premises at certain times and/or on certain days. This predictable schedule of appearance can make churches and related buildings excellent targets for vandalism and theft. However, a digital video church security system can reduce the threat of theft and vandalism tremendously and provide documentation of the event should it occur.

Standalone digital video systems are a great investment as a church security system. Not only can they record acts of vandalism and theft, but simply having digital video church security systems deters most potential wrong doers. In addition, these systems are incredibly versatile which means they can be used in just about any situation or application and they are affordably priced so they can accommodate just about any church budget.

Church security systems require very little maintenance or human intervention when operating. That means on the days that there are no church related activities, the system continues to provide monitoring and security services without the need of an individual to be present to operate.

Church security systems can be used anywhere on church property. Cameras can be placed anywhere inside the church from the vestibule to the altar or apse. Their relatively small size does not usually disturb the aesthetics of the interior design of the church. Cameras can be placed in reception rooms, Sunday school classrooms, storage facilities, and on the property’s perimeter to provide comprehensive coverage.

Basic digital video camera church security systems have from one to several digital video cameras, a processor/Digital Video Recorder or DVR and a monitor. The cameras capture the video image and send it via a coaxial cable to the processor/DVR unit. This unit uses the information to create a digital video file which can be stored on the DVR for later viewing or archiving, or can be viewed live.

Digital video files can be incredibly large in size. A digital video is actually several digital photographs taken in rapid succession, usually about 30 per second. A digital photograph file can be rather large in size, so one can imagine the potential size of a digital video file. The processor uses a software or hardware utility to shrink the size of the digital video file without destroying the quality of the file. This makes the file easier to handle and provides for longer storage times on the DVR.

The digital video cameras used for church security systems have a variety of optional features that allows the cameras to be used just about anywhere. For example cameras can be indoor or outdoor models. Outdoor models are just like indoor models except they contain a protective case or covering that protects them from being penetrated by various types of matter. These cameras are often rated according to an International Electrical code standard called an Ingress Protection rating. When purchasing outdoor cameras for a church security system look for cameras rated IP66 or IP67 as these provide protection not only from dust but from water as well.

Church security system cameras can be wireless too. A wireless camera only requires a small wire for its power supply. Normally, a coaxial cable is run from each camera to the processor/DVR unit; however wireless cameras eliminate this cabling.

A wireless camera has a built in transmitter and antenna that sends its video information in the form of radio waves to a receiver. The receiver is normally located in the same location as the processor/DVR and/or monitor. The receiver converts the radio signal back into an electronic signal and sends it to the processor/DVR for viewing or recording. Wireless cameras are incredibly quick and easy to install and provide for a more aesthetically pleasing appearance since there is no cable running from the camera to the DVR.

Other optional features may include:
• Ability to record audio
• Day/night vision cameras that require very little light to produce an image
• Night vision infrared cameras that can produce a high quality video image in total darkness
• Pan-Tilt-Zoom functions
• Network cameras that use the internet as the network and can implement a personal computer to carry out the functions of the processor/DVR and monitor

As you can see, church security systems are incredibly flexible in application and can provide a high level of “deterrent factor” for theft and vandalism. In addition, these systems are reasonably priced to fit just about any church budget.


Small Business Security System

Tuesday, June 15th, 2010

A small business security system can provide you with the same big business security department coverage at a fraction of the cost. Small businesses have security concerns just like a large business but normally can’t afford the expense for a separate security department and personnel. A small business security system is the solution to your problem.

A small business security system has several benefits:

  • It is reasonably priced and “small business” affordable
  • It eliminates the expense for additional personnel
  • It can provide 24 hour 7 days a week coverage
  • If real-time monitoring is desired, one individual can do it
  • It can cover both the outdoor and the indoor environments of your business

Modern technological advances in the security camera industry have made small business security systems incredibly versatile in application while at the same time maintaining reasonable prices. In addition, small business security systems are component systems, so as your business grows, your system can grow as well.

A basic small business security system is a component system consisting of one to several digital video cameras, a processor or capture board, a monitor, and a digital video recorder or DVR. Since the system is a component system, each component can differ in application or type while maintaining the function of the entire system. This means each component can differ to fit your particular application while still maintaining the function of the system.

Another advantage of a small business security system is its broad application potential. Not only can a system be designed to provide external or perimeter coverage, but the same system can provide internal office or store coverage as well. Further, the system can be a stand alone system or in can incorporate one or more personal computers. This means you monitor your small business in a separate area at your business location or anywhere in the world where there is internet access.

Here is a brief description of just some the additional features/options that are available on small business security system cameras:

Small business security system digital video cameras can be indoor or outdoor cameras. Outdoor cameras are basically the same as indoor types except they are protected from weather and other environmental elements by a case or enclosure. Outdoor cameras usually are rated as to their degree of protection using an International Electrical code standard called an Ingress Protection rating. Outdoor cameras should be at least an IP66 or IP67 rating which means they are completely “dust tight” and can withstand powerful jets of water, or in the case of an IP67 rating, can even be submerged in up to one meter of water.

Cameras normally use a coaxial cable that is run from each camera to the processor to transmit the video image. If cabling is impractical or undesirable, wireless cameras are available. A wireless small business security system takes advantage of the 2.4 or 5.8 GHz radio band technology to send its video data to a corresponding receiver.

Cameras can be purchased for special lighting conditions as well. Day/night vision cameras can produce a high quality color video image in normal lighting conditions and in settings where there is very little visible light. If you need coverage in rooms or areas of total darkness, a night vision infrared (IR) camera may be the solution. These cameras use infrared illumination from IR Light Emitting Diodes or LEDs to “light up” the target area. The IR light is seen by the camera but is invisible to the human eye.

Additional camera options include:

  • Audio recording
  • Pan, Tilt, and/or Zoom (PTZ) options
  • Networking capable via the internet
  • Hidden or disguised cameras

A small business security system needs a processor, monitor, and recorder. Personal computers can be used for this purpose but standalone systems are also available. A typical standalone system contains the processor and DVR in the same unit much like a desktop computer. The security monitor, again much like a computer monitor, connects to the processing unit. Files are saved on the DVR in standard digital video formats so they can usually be viewed by personal computers and most media devices or copied if necessary to give to police or used as evidence.

A custom designed small business security system can provide you with “big business” security at a fraction of the cost. The systems are not only affordable but versatile enough to be used for almost any application.


DVR Camera Security System

Tuesday, June 1st, 2010

A DVR camera security system or digital video recorder camera security system is a practical answer for providing recorded digital video monitoring for business and residential applications alike. These systems are economical and versatile and can include a great deal of advanced features for special applications as well.

A DVR camera security system is a component system much like a component stereo or home theater system in that each of the components can vary to fit individual needs. Yet, the components work collectively to provide high quality security and surveillance monitoring and recording.

A basic DVR camera security system consists of one to several digital video cameras, a processor or capture board that also utilizes special programming or circuitry to make the digital video file easier to handle, a monitor for viewing live or recorded video, and a digital video recorder for storing the digital video files for viewing at a later time or for archival purposes.

There are several camera types and features available to complement a DVR camera security system. Here is a partial list of just some of the camera types and features:

  • Indoor cameras
  • Cameras made specifically for outdoor use
  • Wireless cameras
  • Day/night vision cameras
  • Infrared night vision cameras
  • Pan, tilt, and zoom (PTZ) cameras
  • Cameras capable of recording audio
  • Hidden or disguised cameras
  • Dome shaped cameras
  • Bullet cameras

All of these cameras can produce high quality, high resolution color digital video. Some cameras can be ordered with specially designed programming. For example, a typical PTZ camera when used with specialized motion detection programming can be used to track moving objects such as people or slow moving vehicles.

The digital video cameras of a DVR camera security system usually use one of two different electronic sensors called a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS to create the digital video. The CCD or CMOS works by converting light energy or photons into electrical charges that can be used to create digital video images.

The electrical information created by the electronic sensor is sent to a processor that transforms it into a digital video file. On a typical DVR camera security system, the processor and DVR are contained within the same unit, much like a personal computer. The processor may contain a capture board, a separate integrated circuit board that processes the video images easing the burden on the processor so that it can work on storing, camera control, and other activities.

A digital video file is basically the same as a digital photograph file; except a digital video contains several photographs or frames per second (fps). Smooth, fluid video is normally produced at about 30 frames per second. In other words 30 digital photographs are taken per second. The digital file can become incredibly large in a relatively short time period at this frame rate.

Therefore, to make the digital video files of a DVR camera security system smaller and easier to handle while maintaining a high quality image, a CODEC is normally used. A CODEC is an abbreviation for COmpression/DECompression and is either provided by programming software or “hard wired” into the circuitry of the capture board or processor. The CODEC makes it possible for the processor to store much longer time periods of video on the DVR and to display several digital videos on the monitor at one time.

The monitors used on modern DVR camera security systems are usually LCD monitors like the monitors used with contemporary personal computer systems. The monitors normally connect to the DVR/processor and can be used to display the images that are currently being created by the digital video cameras or to display the digital video files that were recorded earlier.

DVRs are digital magnetic storage disks similar to the hard disk drives of personal computers. Storage capacities range from several gigabytes to terabytes.

A DVR camera security system offers the ability to provide high quality digital video for security and monitoring applications while storing the video files. The added benefit of these systems is that they are usually “stand-alone” systems that can be used just about anywhere.


Security System Camera DVR

Monday, May 24th, 2010

A security system camera dvr or digital video recorder is one of the most common security and surveillance packages used by homeowners, police departments, security agencies, governments and many businesses today. Modern technological advances have yielded a variety of interesting and useful features while keeping prices affordable for not only corporate applications, but for residential applications as well.

A typical security system camera dvr includes one to several cameras, a processor, a monitor, and a dvr. There are many features and upgrades that are available for the security system cameras. The following paragraphs cover some of the most popular and useful features.

Cameras can be categorized based on where they will be used. There are basically two types of cameras based on there placement location: Indoor and outdoor.

Security system camera dvr that monitor and record outdoor activity usually utilized outdoor cameras. These cameras are designed for use in outside environments where they are subjected to weather and other environmental elements. Outdoor security system cameras are normally contained within a case that protects the camera from exposure to dust, water, and other objects. These cameras are often rated based on an International Electrical Code standard known as an Ingress Protection or IP rating.

An IP rating stands for Ingress Protection rating. Cameras for a typical outdoor security system camera dvr usually have a rating of IP66 or IP67. IP66 means the camera is protected from dust and powerful water jets. IP67 means the camera is protected from dust and can be immersed in water up to 1 meter in depth.

Indoor cameras for a security system camera dvr to not have the enclosure that offers protection from the elements as this is not necessary.

Both indoor and outdoor cameras for security system camera dvr may be “wired” or “wireless.” Digital security cameras capture the target area image and transfer it into electronic signals that can be sent to a process or where they are used to recreate a video image. “Wired” cameras send this electronic information via a coaxial cable that is run from each camera to the processor. “Wireless” cameras do not require this coaxial cabling. Instead, a wireless security system camera dvr transmits its electronic information via on-board antennae located on the camera. The only wiring required for wireless cameras is a small line needed to supply power to the unit and on some models; this is replaced with rechargeable batteries.

Digital cameras used for a security system camera dvr can produce a video image in high quality color or black and white; most cameras produce a high quality color image of 420 lines of resolution.

Indoor or outdoor cameras, including both wired and wireless models can also be purchased as day/night vision cameras or as infrared (IR) night vision cameras. Day/night vision cameras produce a high quality color video image using available light. IR night vision cameras for a security system camera dvr produce a high quality monochromatic or black and white video image using near infrared spectrum illumination.

Day/night vision cameras have a very sensitive electronic image sensor circuit that can produce video images in extremely low light conditions such as outdoors at night with no moonlight. However, these cameras must have some visible light available to produce the image, even if the available light intensity is very low.

Night vision IR cameras have a special IR sensitive electronic image sensor circuit that can produce normal color video during daylight conditions, but utilize IR radiation to create a high quality monochromatic video. These cameras normally contain IR Light Emitting Diodes or LEDs that emit IR light. IR light is invisible to the human eye, so these cameras can work undetected in total darkness with no available visible light.

Other functions for cameras include pan, tilt, and zoom (PTZ) options that allow the camera to move about and change its target area or field of view as well as utilize telephoto lens technology to enlarge objects. These features can be controlled manually by remote control or automatically by programming which can be used to track objects or individuals. An example of automatic PTZ is tracking the movement of a car through a parking lot or an individual in a specified area.

Security system camera dvr records the video images in the form of a video data file on the dvr for later viewing or archival purposes. Further, the dvrs can be purchased in a variety of storage capacities to fit any application.

A security system camera dvr or digital video recorder is one of the most common security and surveillance packages used by homeowners, police departments, security agencies, governments and many businesses today. Modern technological advances have yielded a variety of interesting and useful features while keeping prices affordable for not only corporate applications, but for residential applications as well.

Wireless Security Cameras with Computer Monitor

Monday, May 17th, 2010

Wireless security cameras with computer monitor provide excellent security and surveillance for both businesses and residents alike. A wireless security camera system set up with a computer monitor can provide live real-time monitoring of any area, indoors or outdoors in well lit areas or at night.

Wireless security cameras with a computer monitor can be used just about anywhere. A wireless security camera transmits it video images using either the 2.8 or 5.8 KHz frequencies to a receiver that is tuned to the same channel. The receiver then passes the signal on to the processor or a personal computer.

The advantage of using a wireless security camera is that no cabling is required for transmission of data. This has several beneficial implications. First, installation is much simpler and faster. Second, security cameras can be placed in areas that might otherwise be impractical. Third, security cameras can be located in positions that are relatively remote from the processor, digital video recorder or DVR, or personal computer.

Wireless security cameras can be used with personal computers to complete the security system. If this is the case, a computer monitor is ideal for viewing wireless camera transmissions or for playing back recorded data. In this case, the computer becomes the processor and the DVR but a good quality, high resolution monitor is still needed to view the security camera transmissions in real time.

Contemporary computer monitors are typically Liquid Crystal Display or LCD types with very high resolution capabilities. Security system computer monitors usually provide a variety of connection inputs including composite, S-video, component, and personal computer capabilities. Their response times are normally very fast (for example 16ms) which allows for high quality display of multiple video feeds. Computer monitors for security systems often have an amplifier and speakers built right in to the monitor so that audio may be heard as well.

Of all the components of a security/surveillance camera system, the monitor is probably used the most. The greatest advantage to Closed Circuit Television or CCTV cameras is the ability to view the target area in real time; live. For this reason you should choose your wireless security camera system’s monitor carefully. Be certain that it has a high enough resolution display to be able to display all of your cameras’ feeds simultaneously with good clarity and quality.

There are many uses for wireless security cameras with computer monitor. One very popular application for a wireless security camera with computer monitor is in a nursery or baby’s room. These systems allow you to monitor your baby any time day or night by using spot monitors or a central computer monitor.
Another popular application of a wireless security camera system with computer monitor is for monitoring the entering and exit of customers into and out of various business locations. Wireless cameras can easily be installed in lobbies and vestibules where entrance and exit doors are located. Real-time monitoring of every individual that enters and leaves the premises can be accomplished with relative ease.
