Video Security Systems

Written By:
Tuesday, March 29th, 2011

Video security systems are fast becoming the “wave” of the future.  Not only can they document events as they occur, but with Internet technology and other electronic technology advancements, they can even act as burglar alarms and alert you when possible illegal events occur.

A basic digital video security system is a component system that consists of three major components:

1)    One to many cameras;

2)    A DVR or Digital Video Recorder; and,

3)    A monitor or monitors

The system operates in the following manner.  The digital video camera converts light energy into electrical energy which can be measured and is used to create digital video data.  This data is sent to the DVR.  As previously mentioned, the DVR is a digital video recorder, just like the hard disk drive or HDD of a personal computer.  However, in security camera systems, the DVR normally contains a processor, just like the processor in a Personal Computer or PC.

However, the processor in a DVR is a highly specialized piece of electronic circuitry.  Unlike the PC processor, the security camera DVR processor is manufactured to handle specific functions of security camera systems such as digital video file production, camera control, and recording of digital video files.  It uses a specific utility called a COmpression/DECompression or CODEC program to process the digital video file from the digital video data sent to it by the video camera.

Digital video is basically nothing more than a series of rapid digital photographs taken in rapid succession.  Typically, high quality digital video is about 30 digital photographs taken within on second, also referred to as 30 frames per second or 30 fps.  When you think of the file size from just one high quality digital photograph, you can imagine how enormous a digital video file that takes 30 fps for 24 hours could be.

That’s why the DVR’s processor uses a CODEC to create the digital video file.  It uses special programming that shrinks the size of the file without sacrificing the high quality of the image.  CODECS change from time to time as different approaches and technologies make each CODEC better and more efficient.  One of the most popular and recent CODECs is called the H.264 CODEC.

The DVR in a video security system creates, processes, and stores digital video files that can be viewed instantly (live) on monitors or stored for later viewing on monitors or for archiving.  Many DVRs also have additional storage options such as CD/DVD writers or USB Flash drive connectivity to copy portions of video to portable media.  This may be necessary to give insurance companies, police departments, as evidence, etc.

The DVR may also contain other specialized features.  One common feature of many modern DVRs is internet connectivity.  The DVR may contain its own web server technology and programming so that it may be connected to any broadband internet service and instantly become accessible anywhere in the world there is broadband internet accessibility.

Most DVR and security camera systems come in 4, 8, or 16 channels.  This means that the DVR can handle 4, 8, or 16 separate camera inputs at one time.  Security systems requiring more than 16 cameras simply use additional DVRs to expand the number of cameras needed.

Highly specialized security cameras may have highly specialized DVRs.  Portable systems, systems that are used for a small amount of time, systems that have self contained cameras and DVRs all in one unit may utilize different digital storage methods for the DVR.  For example school bus DVR and security camera systems often use a Compact Flash Card or similar portable storage medium instead of a full sized hard disk drive as the DVR.

Is a DVR necessary in a security camera system?  No, not necessarily, but a system with just a monitor and no DVR will not be able to record the video so that it may be reproduced for later use.  A baby monitor is usually a good example of this.  On the other hand, a retail store facility would not realize the full potential of protection without a DVR and security camera system.

Other DVR and video security systems’ functions pertaining to the DVR may include audio recording, various output display resolutions as well as connectors, remote control, e-mail and smartphone notification, and mouse and/or keyboard control.

Home Surveillance Systems

Written By:
Thursday, March 17th, 2011

Home surveillance systems provide security, protection, and monitoring services that can give you peace of mind and keep your family safe.  These systems are based on digital video and digital data; because of this they have the explicit advantage of sharing the benefits of technological improvements in the personal computing industry.  This means exponentially greater performance at less expensive prices.

Typically, most home surveillance systems are component systems made up of three major components or pieces of equipment; the digital video cameras, the Digital Video Recorder or DVR and one or more monitors.  Digital video cameras may be mounted anywhere that’s advantageous to the user; however, standard applications normally provide for exterior perimeter coverage of the home including entrances, exits, and first floor or ground accessible windows.

Inside the home surveillance system can be “zone” type where coverage is based on specific areas of the home and cameras are normally placed in large rooms, hallways, lobbies, and the like or every room may be equipped with its own camera.  This is really a matter of the user’s preference, as are special use cameras.

Special use cameras on the exterior of the home can include a wide variety of cameras and situations.  For example, outdoor cameras (as well as indoor cameras) can be equipped with infrared illumination and the required electronics so as to provide 24 hour coverage, even in total darkness.

More specific uses for the exterior of the home include gate monitoring, driveway monitoring, garage and other detached building monitoring, pet area monitoring, and entrance monitoring.  These cameras can be standard “wired” types or they can also be wireless where the camera transmits a signal to a receiver that is located close to and cabled with the DVR.

Another useful feature for gate and entrance door cameras is two-audio.  Using two-way audio, the gate camera or door camera can act like a security guard that allows you to converse with whomever maybe at the door or gate before permitting them entry.  Each of Security Camera King’s home surveillance systems DVRs supports two way voice technology.

There are many other uses for exterior home surveillance systems’ cameras that are just too numerous to mention here.  The key point is that with all the basic and optional features that digital video cameras have available to offer; they are so versatile that there is almost no situation where they can’t be used.

In addition, there are probably just as many special uses for cameras inside the home as there are outside.  As mentioned earlier, cameras can come with infrared video capability so that when a room is in total darkness, a clear, crisp highly detailed black and white video can still be created.  These cameras are especially useful as baby monitors.   Placed in the nursery with a full open view of the crib/bed and baby/child, these cameras can monitor the infant all night long without disturbing them.  (The infrared Light Emitting Diodes or LEDs that are used to provide the infrared illumination cannot be seen by the human eye.)

Home surveillance systems for inside the home can also include cameras with motion detectors.  These cameras are connected to an on-board PIR or Passive InfraRed detector that turns the camera on for recording only when motion is detected.  The cameras are useful as alarms as well, for the DVR if so equipped, can be programmed to send and email every time the camera is activated.  Furthermore, these cameras save a tremendous about of DVR hard disk space since they only record when motion is detected.

Another highly specialized use indoor home surveillance systems camera is the hidden or disguised camera.  Modern technology has paved the way for these relatively new cameras.  The units are so small that they can easily be hidden inside other normal working objects.  For example, if you need a camera to monitor your home office while you are away, but feel that a mounted camera may appear obtrusive or aesthetically displeasing, you can use a hidden desk clock camera.  The camera is hidden inside the stylish full operating model of a desk clock.

Security Camera King offers all sorts of home surveillance systems and very competitive prices.  We offer 4, 8, 16, and 32 channel systems that come complete with cameras, cable, connectors, power supplies, and a DVR.  We feature three different types of DVRs; the entry level “Elite Mini,” the full enterprise level “Elite,” and our top of the line “Ultimate.”

Security Camera Monitor

Written By:
Thursday, March 3rd, 2011

The security camera monitor is probably considered one of the most important components of a digital video security system.  Yet, it is not purchased as often as other components like cameras and Digital Video Recorders (DVRs) and today’s systems can actually run without one.  In fact, Security Camera King takes pride in offering a complete digital video security package that includes the cameras, cables, connectors, power supply, and DVR but no monitor.  Why is that?  Read on to find out why, and to learn some other interesting facts about the security camera monitor.

There are three types of security camera monitors based on how they are used.  The first is a set-up monitor.  This monitor is only used when the system is first installed or any future changes are made to the system.  It may come in a variety of styles and sizes.  Security Camera King offers, for example, our product number VX-WLCDM, a 2.5 inch LCD service monitor with a wrist strap.

Use this monitor to aim cameras, choose settings on the DVR, and check connections.  Once the system is set up or the changes are made, the monitor is usually disconnected from the system.

The second type of security camera monitor is called the “spot monitor.”  A spot monitor is usually a monitor that is connected to just one camera.  It allows the user to specifically monitor full-time that one area of the security system that the specific camera covers.  The monitor maybe located in close vicinity of the camera it is monitoring or may be located in another location, whichever is most appropriate for the user.

If the spot monitor is used on a “cabled” system, there must be a separate cable run to the spot monitor in addition to the DVR.  This is usually accomplished by adding a splitter to the cable at some point to create a feed to the spot monitor and another to the DVR input.

The third type of security camera monitor is the system or main monitor.  This monitor is generally connected to the DVR by one or more cables and displays the on-screen information of the cameras and the DVR.  Usually this monitor is bigger in size than a spot monitor so that it can accommodate the simultaneous displaying of all or groups of cameras in the system at the same time.

Security camera monitors are like televisions (or perhaps more like personal computer monitors) in composition.  There are basically two types of monitors that are used today, but generally there is only one type that is used the most often.  The two types based on composition are the CRT and LCD monitors.

The CRT or Cathode Ray Tube monitor is the oldest type.  As its name implies it consists of a Cathode Ray Tube that produces the picture.  The CRT monitor is bulkier, heavier, and produces a lower resolution picture than the LCD monitor; basically, its equivalent to the older models of televisions that also used a CRT.  These monitors are still used today, but usually in older systems or as spot monitors.

The LCD or Liquid Crystal Display security camera monitor is probably the single most popular monitor type in use today.  It is much lighter than the CRT, it uses less energy, and displays at a much higher resolution and color, capable of providing quality high definition displays.  These monitors were once limited in size, but as technology advances so do the available sizes.  Security Camera King offers monitors as large as 42 inches.

A monitor is required to initially set-up a system.  However, all systems do not necessarily have system monitors.  The reason for is because once the system is set up it can record and function automatically.  More often however, users have personal computer systems or older monitors from computer systems in which the system is outdated but the monitor is still useful.  Then again, many users opt to connect their systems to the Internet and use any computer system’s monitor or even a Smartphone instead.

One last note; if you are considering purchasing a security camera monitor, regardless of the type, make sure the monitor has the proper connection input type available.  Our DVRs have HDMI, VGA, and BNC connections to make connecting the monitor an easy process for you.  However, many monitors, especially those once used for computers, only have a VGA connection for example.  So be certain to make sure your monitors, camera and DVR display types, and connectors match.

DVR Security System

Written By:
Tuesday, March 1st, 2011

Security Camera King features a DVR security system that can fit every need and budget.   We have systems for four, eight, sixteen, and thirty-two channel applications, and we feature three different models of Digital Video Recorders or DVRs, each with its own unique array of standard features.

Most digital video security vendors prefer to sell the components of a DVR security system individually so they can reap the benefit of charging you a higher price.  Security Camera King offers complete packages that include not only the DVR but the cameras, video cable, power supply cable, camera power supplies and all the connectors.

The only item we don’t include in our DVR security system packages is the monitor.  We do carry a full line of high-quality, competitively priced monitors but we don’t include them in our packaged systems because so many people already have a monitor or simply don’t care to use one directly with their system.

Some of our competitors do offer what they call a “DVR security system” but it usually only includes the cameras and DVR.  Further, they offer you a standard system that they put together and you usually have to take it or leave it.  Security Camera King recognizes the fact that everyone’s digital video security design is unique and may not require the same components.  Therefore, we allow you to make changes and upgrades to “tailor fit” your system at a complete system package price (some changes/additions may include an additional charge).

Even though our systems offer professional, complete digital video security, our systems are so easy to install that you can do it yourself.  Should you encounter any difficulties along the way offer a full range of support services including security articles, security videos, and on-line knowledge base.  However, if these services aren’t enough, we also offer full live support of security experts that can help you design, install, set up, and use your DVR security system.  Our security experts can be contacted by telephone or via on-line live chat, whichever you prefer.

We offer six different DVR security systems that feature our entry level DVR, the Elite-Mini.  They include two different systems each for four, eight, or sixteen channels (i.e. cameras).  The two different systems for each channel category differ by the type of power supply and cables offered.  One package offers a space saving power supply with plug and play cables and the other package offers a power distribution box bulk cables and individual connectors.

Just take a look at all the features we offer in our entry level Elite-mini systems:

  • Four channel audio input;
  • Firmware upgrades by either by downloading directly from the Internet or by USB thumb drives;
  • HDMI, VGA, and BNC video outputs each with high definition displays;
  • H.264 the latest most efficient video compression format;
  • Recording CIF resolution on all channels at 30 fps while two channels are also capable of D1 (almost double the resolution of CIF) at 30 fps;
  • On Screen Display  (OSD) for set up and preference changes and includes an infrared remote control;
  • Playback of 4,8, or 16 channels (based on DVR channel capacity) at the DVR and 4 channel playback via the Internet;
  • A built in Web server with up to 10 simultaneous Internet or network users and Dynamic DNS support;
  • If  you connect the DVR to the Internet, the DVR can send you e-mail alerts and you can view and control your system with your Smart phone using our free apps;
  • FTP, HDD, or USB thumb drive backup options;
  • PTZ mouse control using a simple USB mouse;
  • Linux operating system, a high quality Digital Signal Processor or DSP and the DVR is network ready; and,
  • Each camera comes with a full 1-year warranty and each DVR comes with a full 3-year warranty.

Our Elite and Ultimate series DVR security systems include all of the above features and more.  These systems include a CD/DVD writer, support for multiple hard disk drives, video matrix output, and built in loop connectors that can allow you to output a specific camera to its own monitor.  Last and certainly not least, the Ultimate DVR records in real-time at 4 times the resolution of any other comparable standalone DVR in the digital video security system industry.

So if you are considering purchasing a DVR security system, consider Security Camera King we offer great prices and full technical support.

Small Business Security Systems

Written By:
Monday, February 28th, 2011

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.
