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.

Home Video Surveillance

Written By:
Monday, March 14th, 2011

In this day and age home video surveillance is becoming more of a necessity than an accessory.  Digital video security and surveillance systems are very affordable and meet just about any budget.  In addition, the systems are easy to install and do not require installation by a professional.

Not too long ago, home video surveillance was a luxury that only the incredibly wealthy could afford.  That’s because the cameras and recording machinery were expensive; it normally required a licensed contractor or professional to install the system, and remote monitoring-if it could be done at all, was also expensive.

These were the times when cameras worked on the basis of the analog format only and video recorders were usually tape formats of either Beta or VHS formats.  If one could afford remote monitoring, it was normally done by sending the system’s signal via radio frequency to a nearby monitoring station, which also was expensive.

However, in the late 1990’s to the turn of the century, the digital age had spawned the Digital Video Recorder or DVR.  The DVR was used for many applications including recording television shows from cable or satellite subscribers.  There were many advantages to digital recording as compared to its analog tape counterpart.  One major difference is that the digital recording does not degrade over time like a VHS or Beta Tape.  In addition, instead of using “looping” recording tapes, DVR’s could just start recording over on their hard disk drives.

As we “fast-forward” our account of the video security industry there have been several additional changes that have made home video surveillance more of a commonplace item than a rarity.  Technological advances in electronics as well as computers have yielded powerful, smaller, and more efficient security components such as cameras, microphones, and monitors.

Today’s digital video security and surveillance system is more apt to be a component system.  That is, individual pieces work and coordinate together to produce the outcome of the total system, much like the different peripheral devices of a computer.  This has definitely proven itself advantageous for home video surveillance.  Now homeowners can design systems with specific requirements and meet those needs using different components.  In essence, the age of the “tailor made” or “individualized” home video surveillance system is here.

A typical home video surveillance system consists of three separate components; the cameras, the DVR and the monitors.  Modern digital video surveillance systems don’t even necessarily require a monitor except to set the system up.  However, the monitor is still probably the most widely used component of the system but may become not nearly as important in the future.

This is because more digital systems are becoming Internet compatible.  For example, each of the feature DVRs offered by Security Camera King have built in Web server technology.  That means that once connected to the Internet one or more users can control and view the home video surveillance system remotely, either from another Internet connected computer or a smart phone.  Therefore, the use of a local system monitor is slowly becoming limited.

For that matter, with an increase in technology, newer features and improvements are being regularly added at astoundingly economical costs.  Home video surveillance requires cameras of course, to gather the image (in the digital world this is referred to as “capturing).  The digital video camera features available today seem almost limitless.  Here’s a short list of just some of the features offered for digital video cameras:

  • Infrared based total darkness video capture;
  • Motion Detection;
  • Pan-Tilt-Zoom or PTZ camera movements;
  • Wireless equipment; and,
  • Internet Protocol or IP ready cameras that connect directly to the Internet.

There are as many features available for DVRs as there are uses.  The following is a very short list of the many features offered for DVRs:

  • IP ready DVRs;
  • Motion Detection at the DVR level;
  • Pentaplex operation ( the ability to simultaneously monitor, record, playback, network, and backup);
  • Email notification alerts;
  • Burglar alarm sensor inputs and alarm devices outputs;
  • High resolution recording with high definition playback;
  • Two way voice support; and
  • The ability to add additional internal hard disk drives, CD/DVD writers, external Thumb drives, SD cards and other peripherals.

These are just a few of the features that are offered by today’s home video surveillance systems.  If you are interested in purchasing a system or would like to inquire about one or any of its features, contact Security Camera King today.

Night Time Outdoor Security Camera Kits

Written By:
Thursday, December 23rd, 2010

If you have property that you need to protect or monitor during low or no light conditions consider purchasing night time outdoor security camera kits. These kits can provide you with all the equipment you need to effectively monitor and protect your property, without the need for expensive outdoor lighting. Thanks to modern technological improvements, these kits are reasonably priced as well.

So what do night time outdoor security kits contain? Kits may vary based on manufacturers or vendors, but most kits contain at least two major components of a digital video security camera system: 1) Very low light or no light outdoor security cameras; and, 2) A Digital Video Recorder (DVR) with a Digital Signal Processor (DSP). Since monitor applications differ, and many systems may be able to use an existing computer monitor for your security camera system, monitors are usually sold separately from the kit.

Security Camera King offers a variety of digital video security camera kits including night time outdoor security camera kits. However, in addition to the digital video cameras and a DVR, Security Camera King’s security kits come complete with either plug and play camera cables or bulk cable, and either a multiple channel space saving power supply or a multiple channel power distribution box.

A night time outdoor security camera kit is a highly specialized type of digital video security camera system. These systems contain cameras that are designed for outdoor use and can record video in very low-light or no-light conditions. Let’s take a look at these cameras.

First, there are two basic types of digital video security cameras, indoor and outdoor. Indoor models are designed to operate under the protection of a building or cover of some type. They are not designed to operate when exposed to weather or the elements, such as rain, snow, hail, ice, etc.

Outdoor cameras are designed to operate in outdoor settings, exposed to and offering protection to the camera from, weather and the elements. The cameras are normally enclosed by a protective covering. Outdoor cameras are often rated with an International Electrotechnical Commission (EIC) code or rating that indicates the degree of protection that is provided to the camera. The rating is called an IP code or IP rating.

An IP code consists of the letters “IP” followed by two digits. The first digit indicates the size of the object that the camera is protected from ranging from 0 (meaning no protection) to 6 (meaning dust tight). Numbers from 1 – 5 indicate different sizes ranging from >50 mm to particles the size of dust. The second digit indicates the degree of protection against liquids ranging from 0 (meaning no protection) to 8 (meaning protection from immersion beyond 1 m in depth). For example, a very good IP rating is IP66 which means the camera housing is dust tight and offers protection against powerful water jets from any direction.

Night time outdoor security camera kits normally include digital video cameras that are specifically made for low-light (also called low “lux”) or no-light (infrared) use. “Lux” is a measurement term used to measure the intensity of light. For example, the light available in full daylight, but not directly in the sun ranges from 10,000 to 25,000 lux. In contrast, the visible available light of a moonless clear night sky is approximately 0.002 lux. Low-light or low-lux cameras can record video in lighting conditions as low as 0.002 lux, depending on the quality of the camera.

No-light cameras are usually called night vision infrared cameras. These cameras are designed to record high-quality video using near infrared illumination. The cameras sensor chip can detect near infrared spectrum radiation just like visible light; however, this illumination is invisible to the human eye.

Infrared cameras usually have an array of infrared Light Emitting Diodes or LEDs that surround the camera lens or are placed next to it so that their infrared illumination is focused on the same field of view as the camera. There are also LED “Illuminators,” separate arrays of just LEDs that can provide illumination for the camera also. Generally, the more LEDs the longer the range of the camera, so when purchasing these cameras be sure they have the night time range that you require.

Night time outdoor security camera kits have come a long way with the technological advances in computer and electronic components. Security Camera King offers several different night time outdoor security camera kits. Check out our products under “Security Camera Systems.”
