Pan Tilt Zoom Internet Cameras

Written By:

Pan Tilt Zoom Internet CamerasPTZ or Pan Tilt Zoom Internet cameras have the freedom of mobility to move about a horizontal and vertical axis thereby increasing the field of view for the camera.  In fact in some situations one Pan Tilt Zoom Internet camera may be able to perform the work of two or more stationary cameras.  In addition, the zoom function allows combinations of lenses to create telephoto enlargements for better clarity of objects that may be too far away from a normal camera lens.  These cameras also have the benefit of using the Internet too monitor and control the cameras.

 

Pan Tilt Zoom Internet cameras are excellent for use in retail stores where tracking and zooming in on a potential shoplifter may be needed.  Depending on the size of the store, the location of the camera, and the type of camera, it may be able to follow the shoplifter the entire route that’s made in the store.  Considering the high rate of retail theft that’s been reported lately especially in the major metropolitan areas, Pan Tilt Zoom Internet cameras are ideal for this purpose.

 

Pan Tilt Zoom Internet cameras are not limited to use in parking lots and retail stores; they have many other useful applications as well.  Let’s take a closer look at a Pan Tilt Zoom Internet camera.

 

Pan-tilt-zoom cameras are usually, but not always dome-type cameras.  These cameras are usually mounted on the ceiling with the orientation of the dome (and thus the camera lens) downward.  They may also be mounted on brackets on a horizontal surface (such as a wall or pole) with the brackets extending away from the horizontal surface just enough to provide clearance for hanging the dome in a downward position.

 

Pan Tilt Zoom Internet cameras may be indoor or outdoor models.  Outdoor models are basically the same as indoor models but are enclosed in a protective case or cover.  The outdoor cameras are normally rated according to the International Electrical code standard for the protection they offer from weather and other environmental elements.  This rating, called an Ingress Protection code or IP rating consists of two numbers that represent corresponding protection standards.  For an outdoor PTZ camera, look for a rating of IP66 or IP67.  Both ratings indicate the cameras are dust tight but the IP66 also indicates that the camera can withstand powerful jets of water from any direction while the IP67 also indicates that it could be submerged in up to 1 meter of water without damage.

 

Some PTZ cameras are set manually, but the majority of Pan Tilt Zoom Internet cameras marketed today are remotely controlled.  This is normally done by a keyboard or joystick control connected to the processing unit/digital video recorder or DVR.  If the camera is connected to a personal computer or the Internet, it may use the computer’s keyboard and/or mouse, or may provide software that has graphics that are used to control the cameras.

 

Pan Tilt Zoom Internet cameras may also come with software that can be used to preprogram the movement of the camera.  Programmable preset points will move the camera to that position and hold it there for a predetermined amount of time (often referred to as a “dwell time”).  After moving to each preset point and holding, the camera returns to the first preset point and repeats the cycle over again.  Different cameras have a different total number of preset points available. When looking for a PTZ camera with this option, check the specifications to make sure the camera can be programmed for the number of presets you will need.

 

Most Pan Tilt Zoom Internet cameras also have the ability to detect motion.  This is not so much a function of the camera as it is the programming or software that is controlling it.  However, once these cameras detect a moving object they have the ability to “lock on” to the object and follow it throughout the total range of view for the camera.  If cameras include the zoom option, they can even zoom in on the object while following it.  These cameras are usually referred to as “Auto-Tracking PTZ Cameras.”

 

PTZ cameras are incredibly versatile, easy to install, and reasonably priced making them an excellent choice for many business and residential applications.  Contact one of our security experts today for more information either via Live Chat or by telephone at 866-573-8878 Monday through Friday from 9AM until 6PM EST.

CCTV Home System

Written By:
Friday, September 16th, 2011

If you are looking for peace of mind as far as the security of your home is concerned, try a Closed Circuit TeleVision or CCTV home system.  Today’s systems are so versatile that there is hardly an application that can’t be covered by digital video security.  And, there are many different types of systems for just about every application and budget.

Because electronic and especially personal computer technology has advanced so quickly CCTV home systems have become so versatile that it’s actually hard to find an application that they can’t cover.

First, the term “CCTV” is a carryover from the earlier analog systems.   A CCTV home system was so designated because the entire system was connected by cable in a closed circuit.  This was contrary to a typical studio analog system where the camera recorded the image and past it along to a control room where it was manipulated and amplified and sent out to a fairly large and tall antenna.  Under this system, anyone with a TV could become part of the system (by tuning their TV to the right channel).

A closed circuit television system by comparison was designed to be seen by only those who were directly hard wired into the system, hence the term “Closed Circuit.”  Today, the term is used a little more loosely, but the general meaning still applies.  Even though there are cameras that are wireless and therefore transmit their signals via an on-board antenna, the radio signal is usually a vary specific frequency that designated receivers or DVRs possess to receive the information.  In other words, a CCTV camera security system is still meant for only those people to receive that are within the defined circle of users.

CCTV home systems are rapidly becoming the system of choice for monitoring and protection for residential applications.  One of the reasons for this is because the system is digital.   Since the system is digital, it is able to share a lot of the same equipment and programming as a typical personal computer. This has great beneficial implications for a CCTV camera security system.  For example as hard disk drive technology increases creating storage capacities well into the Terabyte (TB) range, the video security camera system can take advantage of this large storage because video files are stored on such a mechanism.  Greater storage capacity yields a longer turn around time before the DVR re-writes older video files with new ones.

Today’s CCTV home systems are basically component systems which provide even more flexibility.  Generally, cameras and other peripherals to the Digital Video Recorder can be mixed and matched to the users’ utmost benefit.  For example, a typical 8 channel system may have 2 vandal proof dome cameras, an indoor box camera, 3 outdoor dome cameras that also have infrared “vision,” a door monitor camera with two way audio, and a Pan-Tilt-Zoom or PTZ camera covering the driveway and street entrance.

Security Camera King offers a tremendous variety of components to create your own tailor-made system.  Basically, these systems are based on the DVR’s that coordinate them.  Therefore, Security Camera King has 4 of their own proprietary DVRs so we’ll take a quick look at the four.

Elite Mini Economy
This DVR carries the same basic features as the other DVRs with a few exceptions.  It only has VGA and BNC connectors (no HDMI).  A PTZ control interface is also absent on this entry level DVR.  This DVR can record CIF quality on all channels at once, with D1 quality on channel one, all at 30 fps.

Elite Mini HD
This system has everything the Elite Mini Economy has except it does have an HDMI interface and can display high definition at 1080 p.

Elite Series
The Elite series has a multitude of features.  It offers everything the Elite Mini’s offer and more.  For example, in addition to camera hooks up that Elite DVR can accept alarm input channels and alarm output channels.  It can produce a display in High Definition (1080p) but also has video loop output options as well as video matrix output.  This DVR also contains a DVD-RW burner for making backups of digital video files held in storage on the hard drive.  PTZ control is also available on this model.

Ultimate Series

The ultimate Series has everything that the Elite has to offer with the significant difference being in recording power.  The Ultimate Series DVR package includes 520 TVL cameras and can record 704-480 at 30 fps on all channels simultaneously.

Auto-Tracking Dome Camera

Written By:
Wednesday, April 27th, 2011

Have you tried an auto-tracking dome camera?  Be careful if you do because once you get hooked on them, it is pretty difficult to keep you from getting more.  These cameras represent some of the highest quality electronics available today.

What is an “Auto-tracking Dome Camera?”  It’s a special type of PTZ (Pan-Tilt-Zoom) camera that can lock onto moving objects and follow them where ever they go (within line of sight to the camera).

To use such a camera you first need to install it, and then set it up, and finally let it work so you don’t have too!  Auto-tracking Dome Cameras have circuitry built right in that allows them to recognize a moving object, get a lock on the target , and follow it until it leaves the area of the Field of View for the camera.

This is particularly useful if you require constant live monitoring of your security system.  For example, if you were using this camera in a parking lot, not only could you set it to watch cars come and go, but it could even track the people getting out of the cars.

Security Camera King offers two different auto tracking dome cameras, both made by Veilux.  Product# VP-ATDNC27X has an optical zoom of 27X and an additional digital zoom of 10X.  This means the total zoom effect attainable with these cameras would be up to 270X.  In addition here are some of the features of this camera:

  • 520 TVL high resolution output;
  • Minimum illumination is 1.0 Lux for day mode and .5 for night mode;
  • Automatic stabilization of images by reduced flicker;
  • Motion tracking, Intelligent Surveillance with an alarm function;
  • Preset, auto cruise and specified pattern scan function;
  • 360 degree continuous pan;
  • 0 to 9 degree tilt from horizontal plane as well as auto flip 180 degrees;
  • Iris, focus, and white balance;
  • Backlight compensation;
  • Wide Dynamic Range (WDR); and,
  • Outdoor version is IP66 rated for use out doors;

The second camera is very similar to the latter, with some slight advantageous changes.  Product# SVP-ATDN36X has an optical zoom of 36X and an additional digital zoom of 10X.  This means the total zoom effect attainable for this model would be 360X.  This camera is vary similar to the previously mentioned model so the features list will only include those features or items that are different:

  • 540 TVL high resolution output;
  • Minimum illumination is 0.1 Lux for day mode and 0.01 Lux for night; and,
  • Heater and blower included in outdoor model.

It’s only fair to note that PTZ cameras that can be controlled remotely, when coupled with special software on the DVR, can also track or follow objects.  However, in this case instead of the technology lying with the camera, it is actually the DVR that contains the software and does the work.  It uses software to analyze the video sent to it, and then initiates the commands to the camera to PTZ so as to stay with the object tracking it.

So as you can see today’s digital video camera systems can handle some pretty complex tasks without the need for any human interruption.  What’s more is that on PTZ camera mounted in the proper place may often be able to take the place of 3 or even 4 stationary cameras.  Even though the PTZ camera may be in the moderate price range this fact alone helps to reduce costs, if not directly than at least indirectly.

Another added value feature of Security Camera King’s DVRs is that all but the Elite Mini Economy can control PTZ cameras with just a mouse.  Point to where you want to go, and the PTZ camera aims there.  However, if you prefer more conventional means of control, Security Camera King does sell a separate PTZ control that has a joystick and a keyboard designed specifically for use with PTZ cameras.

If you have any additional questions about auto-tracking dome cameras please feel free to contact one of our security experts vie on-line live chat or by telephone at 866-573-8878 Monday through Friday from 9AM to 6 PM EST.

Network PTZ Dome Surveillance Camera

Written By:
Monday, April 25th, 2011

If you are looking for an Internet based camera you should consider one of Security Camera King’s Network PTZ Dome Surveillance Cameras.  These cameras are very versatile with lots of additional features than just Pan-Tilt-Zoom.  In the following article, we’ll take a look at how these cameras work and give an overview on each of these types of cameras that Security Camera King has to offer.

First let’s talk a bit about the camera.  There are IP or Internet Protocol ready dome cameras that may or may not have the ability to pan, tilt, and zoom.  Like wise there are dome cameras that are not IP ready that do have the ability to pan, tilt, zoom.  The dome cameras we discuss in this article are IP ready AND have the ability to pan, tilt, and zoom.  Often times they may be referred to as Network PTZ Dome Surveillance Cameras.

IP cameras are regular digital video cameras with extra electronic circuitry built inside.  The extra circuitry is what is needed to support the camera on the Internet; in other words these cameras do not directly plug into a Digital Video Recorder or DVR.  What they do connect to is a broadband internet connection, usually through CAT5 Ethernet cable.

The camera contains its own Web server technology and once a few pieces of information are provided to the camera’s setup program, the camera begins streaming video via the Internet to either a Network server or to your PC.  You may see an overwhelming amount of 3 and 4 letter initials mentioned under network protocol.  Don’t let these bother you, this is merely a list of the different network protocols that the camera is compatible with.

One acronym that we should mention is PoE.  If the camera is PoE capable (and most, but not all IP cameras usually are) that means the camera can obtain the power it needs to operate with the Ethernet connection, hence the term PoE stands for “Power Over Ethernet.”  This means it is not necessary for you to install a power cable for your camera.

While PTZ camera don’t have to be Internet ready cameras, many IP ready cameras do have “Digital PTZ.”  PTZ or Pan-Tilt- Zoom are movement terms somewhat unique to the photograph and film industry.  Pan means the camera can move horizontally.  Tilt means the camera can move up and down.  Zoom is a function that narrows the FOV and enlarges the appearance of individual objects.

Security Camera King offers four different network PTZ dome surveillance cameras.  The following list those cameras and provides a short summary of their features.

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.
