Indoor Camera System

Written By:
Tuesday, June 14th, 2011

An indoor camera system can be just as effective for providing specific room coverage as an outdoor camera system can in providing outdoor building perimeter coverage.  Indoor camera systems have many more applications than just theft prevention and documentation.  For example, an indoor camera system can also be a baby monitor, a patient monitor, a pet monitor, and an alarm system itself.

Actually there is very little difference between an indoor camera system and an outdoor camera system.  The biggest difference between the two is that indoor camera systems may not contain the proper protection necessary to withstand weather and other natural elements.

Let’s take a look at what makes up an average digital video security and surveillance system and some of the major differences between and indoor camera system and an outdoor camera system.

A digital video security and surveillance system consists of components parts that are universally connectable and useable to create one full-size working system.  In other words an average functioning system has from one to several cameras, a Digital Video Recorder or DVR, and one or more monitors.  This is true whether we are talking about an indoor or outdoor camera system.

The primary function of the camera is to capture light images, transfer them into electronic binary data that can be used to reproduce the image not as a mechanical light system, but as an electronically constructed video image replica of what the camera is seeing.

Although the DVR is basically the equivalent of the “brain” of the system, coordinating and controlling most all of the components of the system, its primary function is to store the electronic video images as a digital video file on some sort of storage medium.  The Hard Disk Drive or HDD is the usual medium for storage; the hard drive is the same as the hard drive in a personal computer.  However, there are also special cameras and systems where many other storage mediums, such as CF cards, SD cards, USB Thumb drives, etc. are used.

Therefore, an indoor camera system consists of however many cameras are needed to perform the job, a DVR, and one or more monitors.  (Actually, after a digital video security system is installed and set-up, it’s not even necessary to have a full-time monitor.)

Indoor camera systems may use any of the different types of cameras like the box camera, the dome camera, and the bullet camera.  Box cameras are designed to be indoor cameras and they work just fine for the job.  (If you want to use a box camera as an outdoor camera, you’ll need to put it in a weatherproof housing that protects it from the elements.)  Dome cameras also make great indoor cameras; one of the advantages of dome cameras is they can be easily flush mounted on the ceiling.  Bullet cameras can even be used indoors.  So it’s basically up to the user as to what type of camera(s) they want to use.

Security Camera King offers a wide variety of cameras, including indoor/outdoor cameras (these cameras may be used indoors or outdoors as they already have the weatherproof protection built right in the camera casing).  The following is a list of indoor(only) camera system cameras that we offer:

Box Cameras

Bullet Cameras

  • All bullet cameras are designed to be indoor/outdoor cameras.

Dome Cameras

As you can see, Security Camera King has quite a vast selection of indoor cameras from which to choose.  Please remember that the lists above contain only models that are indoor camera system cameras, there many, many more cameras that can be chosen for the job not listed above, primarily because they are indoor/outdoor cameras and not just indoor cameras.

If you have any addition questions about indoor camera systems including their camera’s and other components, please contact one of our security experts today.  They will be more than happy to assist you from design, through installation and set up.  Security Camera King has the best support team in the industry and you can contact them via “Live Chat” or telephone.

8 Camera Security Systems

Written By:
Tuesday, April 5th, 2011

One of the most popular digital video security system configuration is the 8 camera security system.   This is especially true for the homeowner with no particular reason other than it seems that about 8 cameras can adequately cover both the exterior and interior of the home.   Eight camera security systems are not limited to homeowners by any means; they also are popular for businesses and other commercial uses.  In the following article, we’ll overview the general characteristics of the eight different 8 Camera Security Systems that Security Camera King (SCK) has to offer.  For specific details, see each systems description and specifications on its own web page.

Before we dive right in talking about the 8 camera security systems, there are a couple of things we should mention.  First, security camera systems are referred to as “X number of channel systems.”  When the word “channel” is used in this manner it normally means the same thing as “camera”; therefore an 8 channel digital video security system can use up to 8 digital video cameras.

Secondly, sometimes the term “channel” is used in a different manner, such as channel A or channel B.   This use of the term normally indicates a radio frequency and not a camera, just like the channel on an FM radio or television for example.

Finally, just for clarification, an 8 camera security system with wireless cameras and a receiver that is referred to as an 8 camera receiver with 16 channels usually means that the system can use up to 8 cameras and the receiver has 16 different radio frequencies to choose from (to prevent interference for example).

Now, let’s talk about Security Camera King’s 8 camera security systems.  SCK has eight different complete package systems that it offers, however, for our discussion; we can narrow this down to four.  Here’s why:  SCK offers systems for sale (as well as individual component parts) because we can offer you a more competitive price on a system than by selling you each component separately.  However we also recognize the fact that every system has different needs.

So, SCK has grouped their systems into different packages based on the most common differences it has found between its customers needs.  Therefore, for each type of 8 camera security system, we offer two different cableing/powersupply/connectors solutions.

In our standard cabling systems, we offer two-4 channel (camera) space saving power supplies, 8 plug n play cables pre-terminated complete with connectors.  The power supplies are typical outlet plug adaptors that have four leads, one to supply power to each camera.  The plug n play cables are 100 feet long each and have a BNC male connector for the camera and DVR at each end as well as a 2.5 mm female power plug.

This cabling system is good for runs that are somewhat uniform and/or if you don’t want to hassle with cutting, stripping, and attaching connectors to cable.  If you have any one cable run that is longer than 100 feet in length however, this will not work for you.

For individuals whose 8 camera security system’s design require cable runs longer than 100 feet, or have varied lengths for most of the cameras, SCK offers the bulk cable package.  In this package we offer an 8 channel power distribution box that adequately supplies the power to each camera from one central location, two boxes of 500 foot long Siamese RG59 18/2 combined cable (combines RG59 video transmission cable with 18 gauge 2 wire power supply cable), and no-tools required twist on BNC connectors for the cameras and DVR and 2.5 mm female power plug power leads for the camera power supply.

Considering that each DVR package type offers two different cabling options, that totals 8 different 8 camera security systems that SCK offers at great competitive prices.  These systems can now be compared based primarily on the DVR types which are the Elite-Mini Economy, the Elite Mini HD, the Elite Series, and the Ultimate Series DVRs.

Of course, each system comes with a full complement of 8 digital video security cameras offering 420 TVL of resolution, our Product# OD-LX420IR50, with the exception of the Ultimate packages where we step-up the game to a higher resolution camera of 520 TVL, our Product# OD-LX520IR50. Both cameras are dome types, high definition color and high definition black and white infrared with an infrared range of about 50 feet.

Once again, check out the individual WebPages for more specific information on each of our 8 camera security systems.

PWR-Mini-4 Output Switching Supply

Written By:
Thursday, March 24th, 2011

There are many options for providing power to your digital video camera security system and Security Camera King’s (SCK) PWR-MINI-4 Output Switching Supply is an excellent choice.  In this article, we’ll take a loot at some of the issues related to powering your digital video security camera systems and examine the solutions that SCK has to offer.

Let’s start from the beginning.  A typical digital video camera security system consists of cameras, a Digital Video Recorder or DVR, and a monitor. Not always, but often the monitor is located very near the DVR.  Most monitors and DVRs operate from 120 Volt Alternating Current (AC) power.  Assuming the monitor is located in close proximity to the DVR, providing a power supply for these two components is relatively easy.  Since they both plug into an ordinary AC power outlet a surge suppressor or power strip would easily serve their needs.

The cameras, however, are a different story.  Most of the digital video cameras today do not operate directly from household current; there power demand is simply just not that high.  That’s why a device like the PWR-MINI-4 output switching supply is needed.  In fact, most digital video security cameras today usually operate on either 24 Volt AC or 12 Volt Direct Current (DC) power.

So the problem is how do you get the correct power supply demands to each camera scattered all over a property and perhaps outside as well?

The worst case scenario for this is providing each camera with a single plug-in power supply.   This however, can be too restrictive as it may not be practical to expect to find an outdoor power outlet fixed to the pole that your driveway camera is mounted.  Not only that, but before you know it things could get just a might bit complicated in the power supply department if you have a 32 camera Elite system and each camera has its own separate plug-in power supply.

Battery operated cameras are fine and some may last a relatively long time between battery changes or recharge periods.  But once again, if that parking lot camera is located on top of a 25 foot pole, who wants to climb it every other day, just to change the batteries?

There’s got to be a better solution, and there is and of course SCK has taken care of that for you.  Since each camera must have a video transmission cable (usually RG-59) run from the DVR to the camera, why not bundle the power line with the RG-59?  However, in order to do this, one would need a centrally located power supply, preferably in close proximity to the DVR since the power leads will terminate in this area with the RG-59 cable.  What’s the solution?  In enters the PWR-Mini-4 Output Switching Supply.  Of course this is not the only solution, but it certainly is one that works.

You’ll note that the PWR-Mini-4 Output Switching Supply comes with SCK’s complete packaged systems with precut-and-connector terminated cables.   This design makes installation even easier since the user (or installer) is not required to cut cable and apply connecters.  All that is needed is for the power cable’s 2.5 mm female power plug to be attached to the power supply’s 2.5 mm male power plug.

For bulk cable packaged systems, SCK offers their model number PWR-4 power distribution box instead.  There is just a little bit more time and effort involved in these installations because the cables need to be cut and connectors need to be fitted.  However, this provides you, the user, with a more custom designed system.

Cables can be cut to exact lengths and runs over 100 feet can easily be dealt with.  All that needs to be done is to attach the 2.5 mm female plug power leads to the camera end of the cable and screw the two wires down to screw terminals for each camera in the power distribution box.

The key here is to use the right power supply for the job.  Too little power and the camera won’t work;  too much power and you could turn that $200 piece of highly complicated technical electronics into one solid melted blob.  That’s why the PWR-Mini-4 Output Switching Supply is so important.

CCTV Systems

Written By:
Tuesday, March 22nd, 2011

The phrase CCTV systems can cover a broad range of different video camera systems.  Generally speaking, when we think of a CCTV system, we are usually referring to a video monitoring, surveillance, and/or security system.  CCTV is an acronym for Closed Circuit TeleVision however, more often then not in today’s age of technology, these systems are often called digital video security and surveillance systems.

CCTV systems got their name because of the way the systems were initially developed.  Closed Circuit Television basically referred to a system by which a video camera transmitted the video images it created through a cable directly to a monitor or Digital Video Recorder or DVR.  This differed from the studio broadcast television that sent their video images through an antenna out to the general public.  Anyone with a television or other type of receiver could view the broadcast audio and/or video image.

Today, CCTV systems are based on the same idea; however, the transmissions are no longer confined to being sent over a dedicated video transmission cable. A CCTV system today may send its video and audio wirelessly on a specific frequency to a specific receiver or they can even utilize the Internet to send their signals just about anywhere in the world (again, to a specific “receiver” or group of individuals).

CCTV systems today share some of the older terminology relating back to the original analog video systems.  For example, older analog CCTV monitors were actually electronic tubes, Cathode Ray Tubes or CRTs to be exact.   These tubes shoot electron beams in horizontal lines on the glass screens to produce a video image.   Thus, the clarity or resolution of these cameras was usually designated by the number of Television Lines or TVLs that it created.  Lower resolution cameras produced around 300 TVL and maximum high definition cameras produce up to 650 TVL.

The cameras and monitors today are digital, and therefore produce their images using pixels, tiny dots of color analogous to the dots seen in newsprint up close.  However, they often still use the TVL designation to define the resolution of the cameras.  One reason for this is that although CRT monitors are seldom marketed anymore, consumers may still have plenty of CRT type monitors they can use for their system.

Today, a complete CCTV system usually consists of one or more digital video cameras, a Digital Video Recorder or DVR, and one or more optional monitors.  Security Camera King offers several complete CCTV system packages to meet just about every security, surveillance, and monitoring need.   Our featured package systems are based on our three signature DVRS, the Elite-Mini, the Elite Series, and the Ultimate Series.

These package systems are further available based on the system being a 4, 8, 16, or 32 channel (camera) system.  Note:  The 32 channel system is only available with the Elite Series DVR.  Finally, we break each one of these packages down based on cable and power supplies.  We offer each system with either “plug ‘n play” pre-cut and connector fitted cables and space saving power supplies or with bulk cable, connectors, and a power distribution supply box.

Our Elite-mini and Elite Series systems come with the appropriate number of 420TVL Vandal Proof Indoor/Outdoor Dome Day/Night Infrared Vision cameras.  The cameras have an approximate infrared range in total darkness of about 50 to 60 feet.  The cameras have an outdoor rating of IP66 and so are very suitable for outdoor or indoor use (our part number for the camera is Product# OD-LX420IR50 for additional details and specifications).

Our Ultimate Series systems come with the appropriate number of 520 TVL Vandal Proof Indoor/Outdoor Dome Day/Night Infrared Vision cameras.  This cameras are true high definition cameras with a resolution of 100 TVL more than those above.  These cameras also have an approximate infrared range in total darkness of about 50 to 60 feet.  They are also suitable for outdoor or indoor use (our part number for the camera is Product# OD-LX520IR50 f0r additional details and specifications).

Security Camera King has put together this system packages to offer you the highest quality yet simplest to install CCTV systems on the market today.  By offering you these as complete system packages, we can make them available at competitive prices that are hard to beat anywhere else for equipment with the same features.  In addition, we allow you to make upgrades if necessary, so that you may “tailor fit” your system to your specific needs.

CCTV Surveillance

Written By:
Tuesday, March 8th, 2011

Thanks to modern technology, CCTV Surveillance has advanced leaps and bounds over the past several years. Not only have systems advanced but prices have dropped considerably making a home digital video security and surveillance system not just something for the “rich and famous.”

CCTV surveillance or Closed Circuit TeleVision surveillance today inherited its name from many decades ago.  The first CCTV surveillance systems were based on analog and not digital video transmission.  In fact the phrase “Closed Circuit Television” was created in reference to actual television cameras.

Television cameras were originally an analog device; that is their signal was sent as an analog signal.  The analog cameras used for live News, Sporting Events, and other “broadcasts” sent their video signal to the studio for processing.  Here the signal was fine tuned; edited if need be, amplified and sent via large antennas to the open public.  Anyone with a receiver (television set) and an antenna could see and hear the video image and audio sound.

Close Circuit Television used the same type of cameras as the cameras used by television broadcast stations, with one exception.  Instead of broadcasting the signal via an antenna to the open public, CCTV surveillance sent its signal through an individual cable that was connected to a specific video recorder and or monitor.  In this manner, the circuit was not available to just anyone.  It was a “closed circuit” that was dedicated to a particular source; hence the name “Closed Circuit Television” or CCTV.

Although CCTV surveillance originally described television only transmitted through a cable, its meaning is used loosely in that regard today.  CCTV today is not necessarily confined to a video image sent over a cable, but may be wireless as well.  However, even though the video images maybe sent using radio frequency signals, they are still directed for use by a specific or finite group of individuals and not the general public.

As a result of CCTV surveillance becoming digital, it has been able to “piggyback” if you will, on the personal computer industry.  In other words, the digital video security industry has been able to benefit tremendously by the technological advancements of the modern day digital world, namely the personal computer industry.

When technology yields a faster computer processor, so too is there a newer, faster Digital Video Recorder or DVR.  When the computer industry develops a larger hard disk drive, so too is there a larger storage capacity DVR.  When the Integrated Circuit or IC chip becomes smaller and performs more tasks, CCTV surveillance cameras become smaller and so on.  This has resulted in remarkable changes in the video security and surveillance industry.

For example, only those who could afford the older, expensive analog equipment could have a home CCTV surveillance system.  Typically, such a system could only be afforded by the incredibly wealthy or commercial businesses that in essence, had to have them, regardless of the cost (banks, retailers, and industrial applications for example).

Now however, digital video CCTV surveillance systems are economically priced and systems are available that fit just about any budget.  For example, Security Camera King sells its Elite Mini complete package system including cameras, cables, power supply, etc. for only $499.  Compared to today’s average prices, that’s not much of an expense at all.

In addition to reasonable pricing, digital video CCTV surveillance systems have also become incredibly easy to install.  So easy in fact, that a professional installer is not required.  A complete home security system can easily be installed as a do-it-yourself project in one weekend or less.

There are other benefits as well.  A contemporary CCTV surveillance system is no longer a proprietary packaged system.  In other words, these systems are component systems such that cameras, monitors, and DVRs can be used from different manufacturers and with different special functions to “tailor fit” the system to your specific security and surveillance needs.

And the benefits keep coming.  Since CCTV surveillance has become digital that means that transmissions can now be sent via the Internet.  All of Security Camera Kings DVRs have this as a basic feature.  Therefore a security system in Florida can be monitored and controlled by a Internet connected computer or smartphone anywhere in the world there is Internet access.

So, as you can see CCTV surveillance has encountered quite an evolution in less than a century of life.  Only imagination can determine what may be yet to come.
