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.

Wednesday, June 9th, 2010

Nothing can provide you with more peace-of-mind about your home than a residential security camera. If you want to be able to “look-in” on your home during the work day, monitor your home from a distant location (for instance, when on travel), or have the ability to record the perimeter as well as the interior of your home, then a residential security camera system is for you. Not only do residential security cameras provide you with the means for real-time security monitoring but thanks current technological advances, they are affordably priced as well.

A typical monitoring system for the home includes from one to many residential security camera(s), a processing unit, a monitor, and a digital video recorder or DVR. There are systems that can use a personal computer in place of the monitor, processor, and DVR and these can save you even more money on the price of the system as a whole.

A residential security camera may be an indoor or an outdoor type camera. Outdoor cameras differ from their counterparts by being enclosed in a case that protects them from the weather and other environmental elements. Often times, outdoor residential security cameras are rated as to the protection they afford from damage by external matter. This rating, called an Ingress Protection code or IP code is based on an International Electrical standard. Most outdoor residential security cameras, unless they will be covered by some other type of covering or protection should be rated IP66 or IP67.

Both ratings indicate that the camera housing protects the inner contents one hundred percent from dust. This is what the first “6” is the code represents. However, and IP66 rating means that in addition, it can withstand powerful jets of water from any direction (the last “6” in the rating). IP67 rated cameras mean that in addition to the protection from dust, they can be submerged in up to one meter of water.

A residential security camera is a digital video Closed Circuit Television (CCTV) camera that can produce high quality color video. In addition to this standard feature, cameras may be able to produce video images in settings where there is very little light or no visible light at all. This is due to the image sensor chips that are used, either a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These integrated circuit chips are able to produce electrical impulses from light that is focused on them from the lens. These electrical impulses are further translated into digital video data.

A day/night vision residential security camera can produce high quality color video in very low light conditions. A night vision infrared (IR) residential security camera can produce high quality color video when there is visible light and high quality black and white or monochrome video under infrared conditions.
A night vision IR residential security camera works by providing its own IR light to illuminate the target area. Generally, these cameras have an array of IR Light Emitting Diodes (LEDs) that surround the camera lens or are next to it that “flood” the target area with IR light. Light that is invisible to the human eye but can be seen by the CCD or CMOS. The LEDs work like an invisible spot light. This particular type of residential security camera works great as a baby monitor or nursery camera. In addition, these cameras can also record audio.

Residential security cameras can be on their own standalone system which includes a DVR to record the video or they can be networked. There are IP ready residential security cameras. IP (Internet Protocol) cameras can be networked using the internet. This means that you can monitor your home cameras any time and any place there is access to the internet. These residential security cameras are particularly useful for people that must travel or as nanny cams that can be monitored from work computers during the workday.

There are several other features or options that are available on residential security cameras as well. Cameras can be purchased with pan, tilt, and zoom options that allow the camera to me moved horizontally or vertically to increase the field of view. In addition, zoom lenses can enlarge subjects using telephoto lenses.

A residential security camera has the versatility to be used anywhere throughout the home. In addition there are several monitoring and recording options available and all can be purchased an installed for an affordable price.

CCTV Video Security Surveillance Equipment

Written By:
Friday, May 28th, 2010

CCTV video security surveillance equipment or closed circuit television video security surveillance equipment can provide all of your security and monitoring needs. Contemporary CCTV video security surveillance equipment offers several features and great versatility along with affordable prices that make this equipment and excellent choice for business and residential applications.

CCTV video security surveillance equipment consists of a few basic components that make up the security systems. Each of these components offers convenient and often highly technologically advanced features that create the versatility of the system such that the equipment can be used for nearly any situation or application. In addition, there are several additional components that can be added to a basic system with ease.

Basic CCTV video security surveillance equipment consists of the following five items:

  • Digital video camera(s)
  • A processor or capture board
  • A monitor
  • A digital video recorder or DVR

Probably the most important component is the digital video camera. Digital cameras for CCTV video security surveillance come in a variety of types, sizes, and functions. Cameras can be classed as either indoor or outdoor cameras. The major difference between the two is that outdoor cameras are built within a casing or enclosure that protects the sensitive electronic components of the camera from the weather and other environmental elements.

These cameras often contain an International Electrical standard code rating that provides the user with a description of the ability of the camera to withstand penetration by liquids and particles. This rating known as an Ingress Protection code or IP code is normally an IP66 or an IP67 for an outdoor CCTV video security camera. IP66 means that the camera is impervious to dust and that powerful water jets from any direction shall have no harmful effects. A rating of IP67 means the camera is impervious to dust and can be submerged in water up to 1 meter in depth.

CCTV video security surveillance equipment cameras can be purchased with other specialized features. Most of these features are based upon recent technological innovations and may increase the cost of the camera depending on the feature and its range of function but are well worth the expense.

For example, most CCTV video cameras create video using a small sensor chip called a Charged Coupled Device or CCD. The CCD converts the light transmitted through the camera lens into an electrical charge that can be detected and used to create high quality digital video. Some CCDs are so sensitive that they can produce high quality video with very little visible light. These cameras, are called day/night vision cameras. Other cameras, called Infrared (IR) night vision cameras can produce a high quality color image when there is visible light present and can produce a high quality monochromatic or black and white image under total darkness conditions when absolutely no visible light is present.

Other features that can be included on CCTV video cameras include a pan, tilt, and/or zoom function, the ability to record audio, and the ability to transmit the video signal from the camera to a receiver using radio waves.

Pan and tilt functions permit the camera to be moved in different directions allowing the camera to cover a wider area of view than one that is stationary. Using pan and tilt functions, one camera may be able to cover the area that may take two or three stationary areas to cover. The zoom function also allows the camera to take advantage of enlarging the field of view, much like a telephoto lens. Cameras can be purchased with the individual pan, tilt, and zoom functions or they can be offered collectively, often referred to as PTZ cameras.

PTZ cameras can be controlled manually, by remote control, and by programming. Programming functions for PTZ cameras can provide automatic tracking functions when utilized with automatic motion detection. For example, the camera can follow a car traveling through a parking lot or an individual in a specific area.
Wireless CCTV video security surveillance equipment normally uses the 2.8 MHz or 5.8 MHz radio band to transmit the video image from the camera to the receiver, which then sends it along to the processor. Cameras come with built-in antennas and circuitry that send the images.

CCTV video security surveillance equipment has seen tremendous technological improvements in just the past few years making the equipment versatile and affordable for just about any application.

On Board High Speed Digital Color Video Camera System

Written By:
Wednesday, May 26th, 2010

An on board high speed digital color video camera system is a somewhat self-contained combination of camera, processor, and digital video recorder or DVR. An “on board” system is usually a portable system that is used on or attached to, something that is moving. A high speed digital color video camera system is necessary because if the camera or the item that the camera is attached to is a traveling fast, the camera needs to be able to capture images faster than usual in order to produce clear video, hence the term “high speed” digital color video camera system.

On board high speed digital color video camera systems have many applications. “Helmet cams” are one such application that enables “hands free” portable video recording because the unit is attached to a helmet that is worn by the user. Some examples of helmet cam use include skydiving, the aerospace industry, medicine, and mining.

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

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

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

Yet another popular application of on board high speed digital color video camera systems is on police vehicles. Police departments across the world are instituting the use of on board systems to provide evidence and monitor activity of potential law breakers. Highway pursuits, disorderly conduct cases during police stops, and an array of other activities are recorded and may be used as evidence if necessary. On board systems in police vehicles also protect officers from false claims of inappropriate behavior.

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

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

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

As you can see there are a wide variety of applications for on board high speed digital color video camera systems and there is also a wide variety of accessories and features that are available to enhance their productivity. Speak with one of our digital security experts to determine which system and features are right for your application.
