Security Camera King offers a well rounded selection of digital video small business security systems.  These systems can provide protection, deter illegal activity, and document any vandalism, theft, or other activity in high-quality color full motion video.  The systems are easy to operate, easy to set up, and easy enough to install yourself if you so desire.

Any business needs security protection, regardless of how big or small the business may be.  Of course, if the business is large enough, it may even have its own security department or security team.  Another option would include contracting the security to an independent security and protection agency.  However, small businesses, especially those that are in the beginning stages of their development, can’t afford these options.

Yet security is still a definite necessity to protect the interests of the business, its property, and its employees.  What is the solution?  Small business security systems can fit this need at a small business overhead price while providing big business security advantages.

Security Camera King offers four different small business security systems based on the number of cameras or channels in each system.  We carry 4, 8, 16, and 32 channel digital video systems.  Each system comes with the designated number of vandal-proof day/night infrared vision dome cameras, the necessary power supply for the cameras, cables, connectors, and of course a Digital Video Recorder or DVR.

Our 4, 8, and 16 channel small business security systems are further divided into three major groups each, depending on the type of DVR selected.  We offer the Elite Mini, the Elite, and the Ultimate brand DVRs.  For any one of these channel groups we actually offer 6 different system packages.  For example, for a four channel system we offer two system packages for the Elite Mini, two for the Elite, and Two for the Ultimate.

The differences between small business security systems packages with the same DVR type are cable and power supplies.  For the complete Four Channel Elite Mini HD DVR Security Camera Surveillance Packages we offer one package that includes a four channel space saving power supply with four plug and play cables.  Our second Four Channel Elite Mini HD DVR package includes the same DVR and cameras, but instead offers a four channel power distribution box, one box of bulk RG-59 18/2 Siamese Cable, four power leads, and connectors.

Each of our DVRs comes with an astounding variety of standard features.  The major difference between our Elite Mini and the Elite and Ultimate DVRs, is that the Elite Mini does not have a CD/DVD writer.  However all of our DVRs provide High Definition Outputs, the latest and most efficient CODEC (COmpression/DECompression) utility, H.264, built in Web server, email alerts, and Smartphone accessible technology.

The Internet options are especially helpful in small business security systems because many small business owners like the opportunity to monitor their systems remotely while they are conducting other business related tasks or even while they are on vacation.  You can use the Web browser access from your home computer to view each of your small business security system’s digital cameras and if you are on the road, anywhere in the world that Internet access is available via a Smartphone, you can view and even control your system via your phone using one of our free applications.

Although the Elite Mini does not have a CD/DVD writer, it does allow you to make backup copies using a USB thumb drive.  The Elite and Ultimate DVRs provide a CD/DVD writer for you to use to back-up your recorded footage or copy specific portions of it to distributable media to give to police, insurance companies, etc.

Security Camera King also recognizes that every small business has its own specific security requirements.  That’s why we offer our systems with component changes and upgrades (some may be an additional charge).  This provides you with the opportunity to purchase a complete system, tailored to your specific security needs, at a reasonable discounted packaged system price.

Since you can actually save costs for your small business by installing your own small business security system we also provide support from the beginning to the end of the process.  Our systems are easy to install and come with all the manuals for the components that describe hook-ups, features, set-up procedures, etc. but we realize that may not always be enough.  That’s why we offer free complete support from design of your system through installation, setup, and use.

Motion Activated Recording

Written By:
Thursday, February 10th, 2011

Conservation is the key term in reference to motion activated recording. In the following article, we’ll take a look at how digital video security and surveillance systems go about doing this and why conservation is a key term associated with this type of monitoring.

Digital video camera security systems can initiate motion activated recording in different ways. One of the most common ways to provide motion activated recording is to use a digital video camera with a built-in motion detector. Digital video security cameras equipped with motion detectors begin recording video when motion is detected and stop when motion is either no longer detected or after a designated (pre-programmed) time period.

The motion detector itself is called a PIR or Passive InfraRed sensor. This sensor constantly monitors the passive infrared signature of the camera’s field of vision. When a significant change in this infrared signature occurs (such as when a person, vehicle, or other object passes by) the PIR interprets this change in the infrared signature as motion.

The PIR sensor on motion activated recording cameras is electronically connected to a relay switch. When the PIR detects motion, the relay is energized to the “On” position which turns on the camera and begins the process of recording. When the infrared signature in the camera’s field of view becomes constant, the sensor interprets this as non-motion and the relay switch is then open, shutting the circuit to the camera off. (Many cameras have an intermediary circuit that is programmed to shut the camera off after a time delay in addition to or after motion is no longer detected.)

One of the biggest benefits of PIR motion activated recording is conservation of digital video security system resources. For example a typical motion activated recording system may have one or more motion activated digital video cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and an optional monitor. The DVR usually consists of a hard disk drive, like the one in most personal computers and in miniature systems may consist of SD cards, small Integrated Circuit (IC) chips, or other portable non-volatile media.

Even though technology advancements are yielding larger capacity and more efficient storage devices, regardless of the type of storage on the DVR, the capacity is still finite. Furthermore, the digital video files created by the cameras and stored on the DVRs are extremely large files. To keep file sizes as small as possible without losing significant quality, COmpression/DECompression or CODEC utilities are used. These utilities may be in the form of software or a hard-wired IC chip.

CODECs greatly improve the storage capacity of any given drive, conserving on system memory. This is important because whenever storage capacity is reached, the newest digital video files are re-recorded over older digital video files. If the files are archived before hand the data could be lost. There are several ways of improving efficiency in addition to using a CODEC. A larger capacity storage medium can also increase re-recording loop times, handle multiple camera recordings at once, and provide storage space for software programs and other necessary binary information.

Another way to greatly improve the storage capacity and efficiency of the camera-DVR relationship is to only record what is necessary. PIR motion activated recordings or PIR motion detector cameras do exactly that. By recording video only when motion is detected, a tremendous amount of memory on the storage medium is conserved. For some applications, motion detection would only be detected if there is a breach in security (banks and retail stores after hours for example) and this could mean no need to record for days or even months.

Memory is not the only resource that is conserved by motion activated recording cameras. Many users these days prefer the use of totally wireless cameras. These cameras send their digital video data via radio signals to a corresponding receiver that is connected to the DVR or to a DVR with a built in receiver. However, these cameras still require a power source which indicates the use of some sort of power supply carried by a wire to the camera – unless the camera is battery operated.

Battery operated cameras may use standard one-time use batteries or rechargeable batteries. Regardless of the type of battery, motion activated recording drastically conserves battery power as the PIR sensor demands a very small drain on the camera batteries as does digital video recording.

Outdoor Wireless Systems Alarm

Written By:
Thursday, September 30th, 2010

An outdoor wireless security systems alarm is usually some sort of motion detector sensor(s) that when actuated initiates some sort of audible or silent signal. There are several variations on this theme, including digital video camera systems that can function as an outdoor wireless security systems alarm. However, the purpose of any of these variations is the same; alert the user when a defined boundary or perimeter has some sort of motion-detectable activity and do it by using sensors that do not require wired connections.

There are several uses for outdoor wireless security systems alarms that work on the basis of motion detection. This sort of system can be used as a welcome chime for your business or home. If your residence has a particularly long driveway these alarms are excellent for notifying you when you have a visitor or delivery.

Likewise, an outdoor wireless security system alarm can be used to alert you to the presence of someone or something (such as an animal) in a boundary or perimeter. These are particularly useful in industrial and other business applications where safety and security concerns mandate that no unauthorized persons are allowed in specific areas. Residentially, a perimeter can be defined around your house or property and whenever this area has been breeched the alarm can alert you immediately, giving you advanced notice of someone’s presence. They are also great for use in securing outdoor swimming pools, water features, or ponds.

There are two basic types of outdoor wireless security systems alarm units, based on their function. The first type is a standalone outdoor wireless security systems alarm and the other is an integrated sensor that communicates with a central control unit that has additional zones connected to it such as doors and windows for example.

A standalone unit usually consists of a wireless motion detector sensor that transmits its signal to a corresponding wireless receiver. The receiver unit is often about the same size as a cell phone and usually contains its own speaker and chime/alarm sound to notify you when the sensor has been actuated.

The integrated sensor consists of a wireless motion detector sensor that transmits its signal to a corresponding wireless receiver that is hard-wired to a central control unit, or to a central control unit that contains its own on-board wireless receiver. Actuation of this sensor sends a signal to the control unit that may react in several ways including sounding an alarm or chime, notifying a professional monitoring service, or even turning on a light or series of lights.

Regardless of how the signal is received, the motion detector sensors basically work the same on the basis of infrared wave technology known as PIR or Passive InfraRed Sensing. The PIR sensor measures the infrared radiation from objects with its range or area of view. Motion detection is based on the change of infrared radiation detected when an object with one heat signature passes in front of another object with a different heat signature. Of course the infrared radiation is invisible to the human eye but readily detectable to the sensor.

Outdoor wireless security systems alarm sensors should be constructed to withstand the elements. Many high-quality sensors have been evaluated to the Ingress Protection Code and have a rating of IP55 or higher. In addition, most outdoor wireless sensor units operate on a standard or rechargeable battery. Some manufactures claim a normal operating period of up to two years on one battery.

Many sensors have selectable fields of view or ranges. It is common for a sensor to contain a switch that can select a 45 foot range or a 15 foot wide angle pattern for example to allow for specific user needs.

Transmission ranges vary based on sensors, manufacturers, types etc. but it is not uncommon to find outdoor wireless security systems alarm sensors that have ranges up to 1000 feet or more. However, most of these manufacturer specified ranges are based on Line of Sight or LOS. LOS range means the distance between the sensor’s antenna and the receiver’s antenna without any objects blocking the view between the two. Generally, objects that do impede the LOS do not necessarily prevent transmission but most often reduce the range. The reduction of the LOS range varies based on the object or material that impeded the LOS such as a window, wall, building, trees, etc.

The cost of an outdoor wireless security systems alarm varies but are normally very affordable for both residential and business applications.

How Do I Compare Home Security Systems?

Written By:
Wednesday, September 1st, 2010

Many people ask “How do I compare home security systems?” There are as many ways of comparing home security systems as there are home security systems available for use, but in this article we will attempt to identify some key characteristics that can help you compare home security systems, specifically home security camera systems.

If you are planning on upgrading an existing system or purchasing a new system, than the answer to “How do I compare home security systems?” should prove to be a useful tool for you.

First, before beginning any comparison of home security systems, it is important that you perform a needs assessment. A needs assessment will help you to determine exactly what kind of equipment or system you need to fulfill your own personal home security requirements. The best way to accomplish this to talk to one of our security experts by telephone or on-line live chat. Simply click on the “Live Chat” button at the top of the page or call 1-866-573-8878 anytime Monday thru Friday between 9AM and 6PM EST.

Here are just a few sample questions you can ask yourself as part of a needs assessment:

• Where do I need camera surveillance monitoring?
• Do I need audio recording as well as video?
• Do I need a wireless security system?
• Do I need professional 24/7 monitoring?
• Do I need to monitor my cameras when I am away from home?
• Do I need special lighting cameras, such as day/night vision or night vision infrared cameras?
• If I use a Digital Video Recorder or DVR, how long do I need to record the monitoring before it is re-written over again?
• Will I need to copy video monitoring stored on my DVR to another medium, such as CD, DVD, or a Flash drive?
• Will my video recording be covert (hidden) or overt (out in the open)?
• How much money have I budgeted for this expense?

Once you have determined exactly what equipment you need, you can go to work comparing components and systems. It’s usually best to “break down” your system into it’s components and compare them individually. If the systems you are comparing have the same like/kind of components then you can compare the entire systems.

For the sake of comparison, the system can be broken down into three basic components, the digital video cameras, the DVR, and the monitor(s). There are features, options, or characteristics of each that you may want to compare. Once again, here is a partial list for consideration by component.

Cameras
• Do my cameras use a CMOS or CCD chip (CMOS chips are usually a little cheaper and may produce a lower quality picture) and what size is it (Generally, the larger the size of the chip, the higher quality of picture.)? Don’t compare a camera with a 3/4″ CCD to a camera with a 1/4″ CMOS.
• What type of lens is being used?
• If it is an “outdoor” camera, what is its IP Rating (How well does it protect the camera from the elements)?
• Do the cameras have wireless technology?
• Are the cameras IP ready (i.e., can they be connected directly to the internet)?
• Do the cameras have any other special features such as infrared technology or Pan-Tilt-Zoom (PTZ)? For example, don’t compare a wireless PTZ camera to a non-wireless non-PTZ camera.

DVRs

• What is the storage capacity of the DVR?
• What COmpression/DECompression (CODEC) does it use to create the digital video file?
• How many channels/camera inputs does it have?
• Is it IP ready to connect to the internet?
• Does it have additional back-up media options?
• What is its maximum recording resolution and frame rate?
• How many audio inputs does it have?
• Can it send email notifications?
• What kind of output (VGA or HDMI for example) does it have?

Monitor(s)
• What is the size of the monitors you are comparing?
• What is the maximum display resolution of the monitors you are comparing?
• What type of inputs are accepted (VGA, HDMI, BNC, etc.)?
• What type of stand or mounting does the monitor have?

Although the question, “How do I compare home security systems?” cannot be answered in just one short article, this should give you a good foundation from which to proceed. Remember when comparing systems to compare like/kind components for the fairest and most accurate comparison.

Camera Security Systems with Cameras

Written By:
Monday, August 16th, 2010

Digital video camera security systems with cameras are the one of the most popular anti-theft, alarm, and surveillance systems in use today. Innovative technology including advancements in the digital video camera industry and computers have made these security devices not only versatile for use just about anywhere, but low in cost to be so economical that businesses and residences alike are using them for protection.

Camera security systems with cameras are basically component systems; they are individual pieces linked together to operate as one system. This produces several advantages for the system as a whole. First, individual parts or devices of the system can be made by different manufacturers. In addition, these components can be purchased so that each individual part is highly customized to serve a specific need, while maintaining the integrity of the total system. This allows “mix and match” system building.

Typical digital video camera security systems with cameras contain three major components: 1) Cameras; 2) Digital Video Recorders or DVRs; and 3) Monitors. Keep in mind that since these are component systems, every system can vary in the number of basic and additional components used. For example, camera security systems with cameras used for industrial areas may contain 16 or more cameras whereas residential camera security systems with cameras may contain only two or three.

Further more, each component type of the system can be different to accommodate the needs of the user. That is, a residential system may have 5 cameras, with each camera being of a different type or for a different function. One camera may be an outdoor camera with day/night vision that monitors a driveway, another may be an outdoor camera with day/night vision and audio recording for monitoring the front door, and a third camera may be an indoor camera that monitors the living room and hallway areas. A fourth camera may be an infrared night vision camera used as a baby monitor and a fifth and final camera may be a motion detection activated camera for protecting a home office. All of these cameras can be used together easily in tandem even though each one may be a different type and model.

In fact there are many features and/or options available for each component of the system. The following is a partial list of the most common features/options available for the components of camera security systems with cameras:

Cameras
• Box, dome, and bullet shaped cameras
• Indoor/outdoor cameras
• Extremely sensitive day/night vision cameras that use very little visible light
• Night vision infrared cameras that use near infrared radiation to illuminate their targets (this “light” is invisible to human eyes)
• “Wireless” cameras that send their video signal via radio waves instead of coaxial cable
• Cameras that record both video and audio
• Internet Protocol or IP ready cameras that can be immediately connected to and networked via the internet
• Cameras that capture high quality black and white or full color video
• Pan-tilt-zoom or PTZ cameras that can vary the position of the camera to increase its field of view — when used with additional programming for the DVR unit these cameras can even track or follow a moving object
• Hidden or disguised camera types for covert monitoring

Digital Video Recorders
• Various storage capacities are available from Gigabytes to Terabytes — the larger the storage capacity the longer the recording time capability and/or the larger the number of cameras being recorded
• Flash card digital recorders are available for small, light-weight portable digital video recording
• Various COmpression/DECompression utilities or CODECs are available for creating digital video files
• Internet ready DVRs that can be networked using the internet
• DVRs that can handle 4, 8, 9, or 16 cameras at one time

Monitors
• These days, most monitors are the equivalent to LCD computer monitors so they can vary accordingly in size, type and resolution
• Small individual camera monitors are also available
• Individual use wireless monitors such as those used as baby monitors

As you can see, camera security systems with cameras have a tremendous variety of features and additional options that make them incredibly versatile. These features combined with the component functionality of the system make them useful for the largest business as well as small residential use. In addition, technological advancements have resulted in economical pricing making these systems affordable for just about anyone.
