Man Watching Security SystemSo you got yourself a Security Camera System and you have your DVR setup either in your bedroom or in the garage and every time you have company or hear a noise outside your home you have to pull out that mobile device and run an application or go where your DVR is located to view those cameras, Here is the solution to that problem so you can view these cameras in all your TV’s just by going to a specific channel on any TV in your home, now you aren’t going to have the ability to change any settings but having the image in all your TV’s gives you peace of mind and it’s a simple shortcut that saves time since you aren’t going to have access to your mobile phone at all times or have the ability to go to the DVR’s monitor. You can also view it in your kitchen while you are cooking as long as the TV is connected to the same system either on a satellite system or a cable system.

What you will need

Satellite TV System

  • Perfect Vision PVDP2 Diplexer Dual Satellite Dish TV Antenna Combiner (PVDP2) Note* Any Satellite Diplexer should work, Perfect Vision Diplexer is prefered
  • Any RF Modulator
  • BNC to Video connector

Cable TV System

  • Any RF Modulator
  • BNC to Video connector

Adapter (Optional)

  • “Y” RCA Splitter / Adapter RCA Splitter

Quick links:
Systems:

Setting up your Satellite TV System

Note* this is for Dish Network System. Some Satellite systems have a switch that has an Antenna input if you are able to provide power and install the RF modulator in a weatherproof box you can do so without the need to add 2x Diplexers for each TV. Consult with your system manual. Illustration 6 shows this type of connection.

Sample system is a Dish Network System (Dual Tuner receiver with agile modulated output) Notice this system serves 2 TV’s.

Back of Dish Network Receiver

Connections:

Find the lines that come from the LNB to the satellite receiver. NOTE* many of these have a switch connected from the Dish LNB that goes to all the splitters or diplexers .

Tap into the line that goes from the Satellite Switch in this case a Dp Plus 44 Switch see Illustration 1, without the Dp Switch see Illustration 2, it is the purple line marked SAT. Connect the sat cable “purple line in illustration” into line in, then the other side of this cable connect the line into the sat in/out. Make sure these connections are like the ones in illustration 3, there is a current going through this line and it could backfeed into the RF Modulator causing it to malfunction or in worst case scenario rendering the RF Modulator useless as it would burn up the internal components.

Illustration 3 shows the connection required from the RF Modulator to the diplexer which is injecting an RF Signal to the existing line.

Setting up your Adapter

Adapter is optional and it will only work in single channel mode, meaning one channel has to be in full screen for that one channel Adapter to work unless the Adapter is tapped from the microphone to the DVR using a ”Y” splitter Adapter cable. No Adapter connection is needed at the receiver end since it will be added to the RF Signal . See Illustration 4 for the cable needed.

Illustration 5

connections to dish receiver

Connecting the Satellite Receiver is very simple, on Illustration 5 connect SAT Cable from the first diplexer we already installed to the top in/out ‘A” on the diplexer after that connection is made connect the antenna to the TV in/out on the diplexer “C” and finally connect “B” Sat in/out to the Sat in on the Satellite receiver.

Once you have done this you are done when it comes to making all connections the rest is done via the on screen settings in your receiver.

Searching for your local channels after the connections are made

Power up your Satellite Receiver and go to the Menu by pressing the menu button in your remote then select option 6 which is “System Setup” , go to option 8 “local Channels” on the new window select local channels , select “Scan Locals” your receiver will now scan your local channels , the local channels that the receiver found will not be displayed on the left of the screen. You can highlight each channels to see the channel strength after that you can hit “DONE”, then you can press “CANCEL” twice to exit the menu, finally go into your guide and search the channel that the RF Modulator is on, Channel 65 or a channel that is not being used by any station is required since those channels will cause interference.

Once you have selected the channel in your RF Modulator and tuned into the same channel in your TV you should see all your cameras in that channel as well as Adapter only if you have installed the optional Adapter splitter or selected the Adapter out from your DVR.

Setting up your Cable TV System

Setting up your Cable TV system is much easier than setting up a satellite system with your DVR and RF Modulator.

The system we will be installing this RF Modulator will be a Comcast system with internet.

Covert or Overt?

governmental, personal and commercial security
When it comes to governmental, personal and commercial security, one might wonder, is it better to be Covert or Overt.
In other words is it better for a cop to sit hidden on the side of the road waiting to catch someone speeding, or would it be more advantageous to wait in plain sight, sporting a bright orange police car that could be seen from miles away?

Is it better to catch a person who committed a crime or prevent the crime from happening in the first place?

co•vert


  1. Not openly acknowledged or displayed.
    “covert operations against the dictatorship”
    synonyms: secret, furtive, clandestine, surreptitious, stealthy, cloak-and-dagger,hole-and-corner, backstairs, backroom, hidden, under-the-table,concealed, private, undercover, underground;

o•vert


  1. Done or shown openly; plainly or readily apparent, not secret or hidden.
    “an overt act of aggression”
    synonyms: undisguised, unconcealed, plain (to see), clear, apparent, conspicuous, obvious, noticeable, manifest, patent, open, blatant;

This is something you might want to consider when choosing your CCTV security system and cameras.

Do you want the cameras to be noticeable? That might make potential criminals think twice and hopefully deter them compliably before even committing a crime?

Do you want your cameras to be inconspicuous or even totally hidden?

scary cam bot
There are arguments for both, but it really depends on what you are trying to achieve.

Many people like for their security cameras to be very visible or overt. They believe that the noticeable presents of the cameras, is the first level of their security system, and will aid in preventing a possible theft or vandalism.

Although there are many styles of cameras available today, some people prefer to choose cameras with a very “Traditional Security Camera” look. This is usually a good option for retail stores or marketplace type businesses.

A good example of an overt security camera is the OB-EF700IR100L2812D-W Varifocal Bullet Security Camera sold by securitycameraking.com.

On the other hand there are people who are not only concerned with security, but the aesthetics of the cameras. This may be the case if you are a home owner or the proprietor of a business that caters to luxury, like a fancy boutique or restaurant.

In cases like this one may choose a more sleek and covert security camera like the 1.3 Megapixel IP Network Indoor Dome by Tech Pro Security Products.

Another situation may be when you are not necessarily trying to prevent a crime, but one where you absolutely want to catch someone RED handed. Maybe that sneaky babysitter or catching you’re cheating husband! If so you might need a hidden security camera. These are cameras that are totally hidden from view or disguised as other items completely.

Popular models may look like, smoke detectors, motion detectors or even a stuffed animal like the popular, teddy bear security camera. Here are a few more that you might find interesting.

Should You Just Fake It?

Maybe you are the type of person that feels a deterrent is good enough, or you just don’t have the cash for a full blown security system. Don’t fret, you have another option. You can get fake or dummy security cameras.

At first you might think this is a ridiculous idea, but think about it. You could give the appearance of being protected by security cameras, for a fraction of what it would cost for a full (working) security system. On top of that, installation is a snap.

fake


  1. a thing that is not genuine; a forgery or sham.
    “the painting was a fake”

    synonyms: forgery, counterfeit, copy, pirate(d) copy, sham, fraud, hoax, imitation, mock-up, dummy, reproduction;

Should I Hide My DVR or Even Lock It Up?

Another thing you might want to think about is the placement of your DVR (digital video recorder) or NVR (network video recorder).
Most people might say, that’s easy, I will just put it near the rest of my electronics or in a place that is easily accessible.

If you using your cameras to keep an eye on the kids, or see who’s at the front door, that might be fine. But think about this, what good is catching a thief on camera if he decides to steal your DVR/NVR along with your brand new, 60″ LED smart TV? No recorder, no way to review the recorder video.

For this reason many people prefer to keep their recorder in an inconspicuous place, like in a bedroom closet on the top self. Another option is to use a lockbox. DVR or NVR lockboxes are exactly that, a metal box that encases your recorder. They can be locked and permanently mounted. This will ensure that the recorder cannot be easily stolen or tampered with. Both the lockboxes and mounting brackets can be found on www.securitycameraking.com

How will I view my Live or Recorded Video?

Many of the newer model recorders have VGA, HDMI and BNC video outputs built-in. You can simply hook up a monitor directly to the unit as you would any standard computer or laptop.

As a matter of fact this is the most common method used for the initial setup of the recorder. Once the setup is complete, you may want to leave the monitor connected. Then you will just manage the recorder or view your live or recorded video directly at the unit.

If your recorder has a network card and supports remote viewing, you can also disconnect the monitor and view or manage it remotely. All TechPro Security Products DVRs and NVRs have several options for remote viewing.

These options include using a web browser on your computer or laptop, as well as being able to use mobile devices such as iPhones, iPads, Android phones and tablets.

Conclusion?

As you can see when choosing a security camera system, there are several factors to consider beyond just the basics. With a little extra thought and planning, you will be sure to choose a solution that will fit your needs for the long term.

Security Camera CCD

Written By:
Tuesday, June 21st, 2011

We are asked quite often about the security camera CCD (Charged Coupled Device) and the CMOS or Complementary Metal Oxide Semiconductor.  In the following article we’ll discuss how a digital video system actually works and what importance a security camera CCD has within this system.

First let’s describe a digital video security and surveillance system.  It normally consists of three components; the camera(s), the Digital Video Recorder, and a monitor(s).  The camera’s function in this system is to capture a video image created by light reflectance and transform it into an electronic image based on electricity.  Both live and recorded material is played back by the DVR and may be seen by watching the monitor.

So now that we have a general idea of what each component does, let’s talk specifically about the camera and the security camera CCD.

A digital video camera works by using a combination of mechanical (lenses) and electronic (Integrated Circuit or IC chips and printed boards).  Whatever direction the camera may be pointed in, the area that you will see as a point of view from the camera is called the camera’s field of view.  The field of view is the specific area that will constitute the video image.

The field of view can be made larger or smaller depending on the focal length of the lens.  A standard lens has one focal length and therefore on field of view.  Varifocal lenses can vary their focal length (either manually or remotely).  The field of view contains objects that reflect light.  This reflected light is captured by the lens and when in focus, the lens focuses the reflected light on a sensor chip which is usually only 1/4 to 1/3 inches square.

This sensor chip, in our case, is the security camera CCD.  As the focused light strikes the security camera CCD, tiny pixels on the sensor emit a very small but measurable electric impulse.  Their may be more than one CCD and their maybe the use of one or more filters involved as well.

Once the light strikes the security camera CCD, the CCD gives off it’s electrical pulses and this are measured and interpreted by the analog to digital processor IC chip.  This is when the video image becomes digital.  As the processing continues in the camera, the camera’s Digital Signal Processor or DSP, in essence another IC chip, makes adjustments to brightness, color intensity, contrast, etc. to make sure the video image is of the highest quality.

Once the video image information, now binary or digital data is sent to the DVR the DVR stores it or plays it live.  Either the camera or the DVR compiles the binary data and creates a digital video file out of it.   These digital video files are the same type of digital video files that can be watched on a personal computer.

The security camera CCD (and the CMOS) has a unique feature about it that makes it even more versatile.  The CCD inherently can also create video images using on infrared light.  Infrared light is invisible to the human eye, so this makes for a very powerful, useful security device.  Most night time infrared cameras have an array of Infrared producing Light Emitting Diodes or IR LEDs that are arranged around the lens of the camera.   The human eye cannot see their light, but to the CCD, they work like using a floodlight.

In addition to the array of LED’s around the camera lens, IR LED illuminators may also be used.   Illuminators are just a group of more IR LEDs to add more light to the picture.  Some illuminators boast IR ranges of as much as 300 feet when using the illuminator along with the camera’s own lights.

Incidentally, since this type of video construction is done with only IR light, the image will be in either black and white or monochromatic.  But very seldom will the detail or resolution degrade so the IR video image is as good of quality as the day time color versions.

Security Camera King has a large variety of security camera CCD cameras and systems.  Be sure to check the “Specification” tab when looking at a camera that you may be considering to purchase to make sure that the camera gets the proper night time range that you will need.

Remote CCTV System

Written By:
Friday, May 6th, 2011

There was a time in the not-so-distant pass where a remote CCTV (Closed Circuit TeleVision) system would be unheard of.  Today, thanks to the leaps and bounds of electronic technology, all of Security Camera King’s featured packaged systems include remote control of the system as a standard feature.

Security Camera King offers several different complete system packages and very competitive prices.  These systems are based on the number of cameras and the type of Digital Video Recorder or DVR.  We offer 4, 8, 16, and 32 channel systems that should appropriately fit just about any application.

In addition, we offer 4 different DVRs.  Each DVR has slightly different features (usually on the plus side) that make them suitable for your specific situation.  We offer the Elite Mini Economy, the Elite Mini HD, the Elite Series, and the Ultimate Series DVR systems.  Each one of these systems can be a remote CCTV system.

Before we go any further, let’s create a definition for remote CCTV systems so we know just exactly what we are talking about.  Each one of the DVR systems previously mentioned above come with an InfraRed or IR remote control that can be used to operate the DVR.  By strict definition of remote, each one of these systems qualify as a remote CCTV system.  However, this is not what we are talking about, in this article at least, when we say remote CCTV system.

Our definition of a remote CCTV system is one that can be easily controlled by an individual who is no where near the system.  Here is a good example:

You’re vacationing in Rome and are standing in line waiting to enter the Sistine Chapel, when you suddenly get the feeling you should check back with home because of the escalated rates of vandalism that have been occurring in your neighborhood lately.

So you get out your iPhone and start the application for your digital video system and while you’re standing in line you view each one of your cameras.  In addition, one is a Pan-Tilt-Zoom (PTZ) camera that covers your entire driveway.  You can control this camera right where you are to get a good view of your entire home and drive way after manipulating the PTZ by just using your iPhone.  You find that everything looks ok, and you have a better peace of mind feeling, just before you are ushered into the chapel to view the beautiful art work.

To some, this may sound a little like science fiction but it’s not.  Furthermore, it’s very easy to achieve with this remote CCTV system.  No matter where you are located, as long as you can connect to broadband internet through your 3G or 4G telephone you’ll always have remote control access.

In fact, you don’t have to have a smartphone to operate your CCTV system remotely.  You can even use a personal computer or Mac with a Web browser to access your system remotely and it only takes a couple of minutes to set up the system to do so.

How is this possible?  First, all of our DVRs run on an embedded Linux operating system.  This also includes the technology for an embedded Web server.  Just connect the DVR to a broadband internet perform a little set up work and you’re ready to “Go Remote.”  For those that are techno-savvy, our DVRs also have Dynamic DNS support, another indication of the versatility of these systems.  Since it is not necessary to have a Static DNS this saves you money (normally, Internet Service Providers can provide you with a Static DNS but will do so for an additional monthly fee).

Another function of our DVRs that contribute to the remote CCTV system is email capability.  Instead of checking your system all the time when you are on the road, you can have your system send you an email based on your own criteria.  You can then use your smartphone to access y our system and “see what’s up.”

As you can see, remote CCTV systems are no longer science fiction and are a very dynamic feature for your digital video security and surveillance system.

If you have any additional questions about remote CCTV systems, please feel free to contact one of our security experts.  They can be reached on-line through the “Live Chat” feature or by telephone at 866-573-8878 Monday through Friday from 9AM to 6PM EST.

PTZ-TOOL Programming Module

Written By:
Thursday, April 14th, 2011

The PTZ-TOOL programming module makes programming PTZ cameras a cinch.  Security Camera King offers this for sale for customers because there are many people that have more than 1 PTZ (Pan-Tilt-Zoom) camera in their system.  In fact, this tool is only required if you use more than 1 PTZ camera in your system, but it can be used to control a standalone PTZ camera as well.

PTZ cameras make for a powerful addition to a digital video security system.  Often times, these cameras can take the place of two or more stationary cameras making them very cost effective as well.  These cameras usually come with factory pre-settings and it may be useful to “tweak” them a bit; that’s where the PTZ-TOOL programming module comes in.

Before we talk about the PTZ-TOOL programming module itself, let’s take a look at what makes up a digital video system and exactly what a PTZ camera can do in that system.

A basic digital video security and surveillance system normally consists of three components; one or more digital video cameras, a Digital Video Recorder or DVR, and one or more monitors (a monitor is needed for the initial setup of the system, but once the system is up and running a monitor is actually an optional choice).

The cameras’ primary function is to “capture” video images created by light that reflects off objects in the cameras’ field of view.  The lens focuses this light onto a small sensor that ranges in size from 1/4″ up to about 1/2″ square.  When light strikes its individual units (pixels for example) the sensor produces an electrical impulse that can be measured.  These electrical impulses are used to create a video image that can be displayed on an electronic monitor and/or compiled into a file that can be stored on the DVR’s hard disk drive.

There are many different ways to increase or decrease the field of view for the camera.  One way is to use a varifocal lens.  These lenses however are often only manually operated and can only enlarge or reduce the field of view.  Another way to increase security coverage is to use more than one camera in such a manner that their fields of view overlap just a little.

The third way to increase coverage is to use a PTZ camera. A PTZ camera can normally pan 360 degrees or a full circle and have a vertical movement of at least 180 degrees.  In other words, picture an object that looks like a sphere cut in-half.  Now imagine the camera lens in that half-sphere; generally this is the area that the camera lens can move/rotate through in order to capture video images.

PTZ cameras have become very popular, due to their extreme versatility and advanced electronically controlled features.  However, there are so many different features and functions that it may seem somewhat overwhelming to the do-it-yourselfer.  The PTZ-TOOL Programming Module helps to make the task of changing PTZ settings easy.

 

The PTZ-TOOL Programming Module is designed for use with Security Camera King’s PTZ-LX550L3X Pan/Tilt/Zoom Camera and our PT-LX540 Pan/Tilt Camera.  If you use more than one PTZ-LX550L3X or PT-LX540 Pan/Tilt Camera you will need the PTZ-TOOL programming module.  One of the reasons that this tool is required when using more than one PTZ or PT camera is so the address of the camera can be changed from the setting of “1.”

The DVR has virtual “ports” that are assigned to the cameras to keep them separate for the DVR’s sake.  These virtual ports or addresses can range from 0-255.  Programming the camera to a different address allows the DVR or other device to control that camera only.  It’s the equivalent of a first name when talking about someone in a particular family.  If you used the surname only, no one would know who you were talking to; mother, father or siblings.  However, when you use a first name, then the individual knows exactly who you are talking to (addressing).

With the Programming Module for PTZ-LX550L3X and PT-LX540, you can assign different addresses (first names) to the cameras so that the DVR can keep track of them.

If you have any additional questions about the Programming Module for PTZ-LX550L3X and PT-LX540 contact one of our security experts today either by on-line “Live Chat” or by telephone at 1-866-573-8878  Monday through Friday from 9AM to 6PM EST.
