The Pan Tilt Zoom camera or PTZ is one of the most versatile dome cameras on the market today. Not only does it offer the standard electronic features of most other dome cameras, but the PTZ can do just that–Pan, Tilt, and Zoom.

In the video industry, Panning is the ability of the camera to about a horizontal plane, simply put turning from left to right and all the way around in a circle.  Tilting refers to the cameras ability to move about a vertical axis, once again simply put up and down.  With no walls, poles, or mounts to impede the view, a pan tilt zoom camera can easily maneuver its lens in any position equal or greater to that of an area covering 1/2 sphere.

In addition Pan Tilt Zoom cameras have the ability to change their focal length such to allow a field of vision that can range from “wide angle” to “Close-up” depending on the lens.  This lens movement and/or electronic (digital) action is called Zoom.

Pan Tilt Zoom cameras usually have a motorized mechanism that moves the camera about the axis, although some may also be able to perform these functions on a limited basis electronically.  When this technology is coupled with motion detection or object (shape) detection, the PTZ camera can be elevated in application from not only its PTZ functions but can also perform auto-tracking and following.

Security Camera King (SCK) offers a variety of Pan Tilt Zoom Cameras which range in price from $199.95 to $985.99.  SCK’s PTZ-LX550L3X is an affordable solution for a PTZ camera priced at $199.95 with a resolution of 550 TVL!  This camera has a 3X Zoom lens with 360 degree continuous rotation pan.  It can tilt from 0 to 90 degrees and flip.  The maximum pan speed is 60/sec, tilt 30/sec, and the present speed is 100/sec.

The PTZ-LX550L3X offers 32 preset points with pattern tours including programmable 16 preset point number and dwell time/speed.  The camera can auto scan as well as be programmed to auto return to its home position.  This camera is rated IP66 for outdoor use so it can be used as an indoor or outdoor camera.

Our PTZ-HN03100 is the perfect solution for a hands down high quality Pan Tilt Zoom camera that works well with any of our featured Digital Video Recorders or DVRs.  This camera is also a super high resolution camera weighing in at 540 TVL.  It is vandal proof, IP66 rated with the outdoor mount, has auto gain control, auto white balance, and an on-screen display.  In addition it offers 10X optical and 10X digital for a combined 100X zoom capability.

Next in line is our SVP-54CDN10X 540 TVL Mini Dome Surveillance Camera.  This is a Veilux camera and as many of our customers attest on their reviews, you can’t go wrong with a Veilux when it comes to quality.  This mini camera may be small but it delivers BIG results.  It offers true day/night with color day time video and black and white when the ambient light becomes less than .02 Lux.

This camera offers up to 256 presets and it offers high speed pan and tilt.  This camera even comes with its own wall mount!  Priced at $664.50 it’s a professional level camera that offers professional results.

SCK offers two different models of auto tracking Pan Tilt Zoom cameras.  The first, Product# VP-ATDNC27X is priced at $707.69 and includes day/night capture and 27X zoom.  Once again this is a Veilux brand camera and stands for high quality.  The second model is SCK’s SVP-ATDN36X and is also a Veilux camera similar to the first with the major difference being an increase in zoom capability to 36X.

Regardless of the model you choose, a Pan Tilt Zoom camera is a versatile, powerful, and cost savings camera.  When these camera are placed properly, one camera can easily replace the need for 2, 3, or 4 otherwise stationary cameras.  In addition, if standard non-PTZ cameras were used, these Pan Tilt Zoom Cameras also offer the powerful zoom function that allows you to get in close.

Home Door Security Systems

Written By:
Tuesday, June 29th, 2010

Are you unable to see through the peephole on your front door? Would you like to be able to see who is at your door before they see you? Home door security systems could be the answer for you. Home door security systems can range from a very simple one-camera system to a more complex multi-camera system with entrance controls.

A simple home door security system consists of a digital video camera and a monitor. The camera is placed in an appropriate location so that it best captures the identity of the person or person knocking on your door. The monitor may be located anywhere within the house that is the most convenient for the user. A transmission cable is run between the camera and the monitor. The unit is generally in a continuous “on” state so that potential guests can be seen approaching the door.

A more sophisticated setup may include a Pan-Tilt-Zoom (PTZ) camera and monitor. If used correctly, a PTZ home door security system can take the place of two or more cameras. A PTZ camera can move about a horizontal or vertical axis increasing the field of view for the camera. In addition, the zoom function permits the user to use the telephoto capabilities of the lenses to enlarge the field of view. Using a PTZ camera, you can easily enlarge the field of view to get a close up of the visitor’s face.

Another more sophisticated home door security system setup may include more than one camera. A camera can be placed at every exterior entrance/exit of the residence. This provides the homeowner with the ability to monitor all the doors of the residence from one central location.

You can take advantage of the audio feature for your home door security system too. Most digital video cameras have the ability to record audio as well as video. You can easily monitor sound by using a setup that has a monitor with speakers. Some systems also have two-way audio, which allows the user to interact with the visitor as well.

Finally, the ultimate home door security system could include not only a camera monitoring system, but a remote entrance control as well. You can install remote door locks that can be unlocked (or locked) at the push of a button. Used in combination with a camera with two-way audio and a monitor, this is the ultimate in safety and security for a home door security system.

As visitors approach the door you can monitor both video and audio. When the visitor knocks on the door, you can greet the visitor or inquire as to their visit, before allowing them entrance to the premises. Once you have decided to grant the visitor(s) access, you can remotely unlock the door and invite them in. These systems work great not only with security as the primary consideration, but they are especially useful for physically challenged individuals that would find it difficult to greet every visitor at the door.

Home door security systems aren’t limited to just doors either. The same sort of set can be used on entrance gates to properties, providing even greater preemptive security monitoring, especially when combined with a remote automatic gate control.

Also, home door security systems aren’t just limited to use in single family homes; they can be utilized for apartments or condominiums as well. This is especially useful if you live in a multi-apartment building and there is no fulltime door man or building monitoring system. In this case a camera could be monitored on the exterior of your wall next to your door. Or, if you want to use something less noticeable, you can use a very small “pinhole” type wireless camera mounted on your door itself.

Thanks to the versatility of digital video security cameras, there are literally dozens of ways to set up a home door security system. In addition, modern innovations in electronics have driven component prices down so that these systems are reasonably priced.

If you are looking for a simple and affordable method for monitoring visitors at your residence, a home door security system is a cheap and sensible investment.

Home Camera System with DVR

Written By:
Friday, June 25th, 2010

A home camera system DVR or Digital Video Recorder is a standalone digital video security camera system suitable fur residential use. Recent advances in computer and electronic technology have provided the home camera system DVR user with an abundance of optional features, making the system versatile enough to be used just about anywhere.

A home cameras system DVR is basically a component system. There are different parts that make up the entire system and each individual part can differ to provide a specific function. These “parts” are the components and when put together create the system.

A typical home camera system DVR consists of the following components:
• Camera or cameras;
• Power supply;
• Processor/Digital Video Recorder with CODEC utility; and,
• Monitor

Cameras used in a home camera system DVR may be indoor or outdoor types. Outdoor cameras have a protective cover that keeps dust, water, weather and other environmental elements from penetrating it and harming the camera. These cameras are often rated based on a standard called an Ingress Protection or IP rating. When shopping for an outdoor camera, make sure it has a rating of either IP66 or IP67. Both ratings indicate complete protection from dust and water.

When creating your own custom home camera system DVR, you generally will require both outdoor and indoor cameras. Outdoor cameras may be used for monitoring the perimeter of your residence or for specific outdoor areas. Indoor cameras are generally used for monitoring rooms, doors, and areas inside the home.

Regardless if the camera is an indoor or outdoor model, each camera will need to be connected to a power supply, and a coaxial cable will need to be run from each camera to the processor/DVR. However, the coaxial cable can be eliminated by using wireless cameras instead.

A wireless home camera system DVR differs from a standard home camera system DVR in that each camera has its own transmitter and antenna. The camera transmits its video signal using the 2.4 or 5.8 GHz radio band to a corresponding receiver. The receiver is usually in the same location as the DVR. The receiver passes the radio signal in electronic form to the processor/DVR. Wireless cameras are quick and easy to install.

The digital video cameras used in a home camera system DVR are state-of-the-art electronic devices. They create a digital video image by capturing light from the lens on a special electronic sensor chip. There are two types of sensor chips; Charged Coupled Devices or CCDs and Complimentary Metal Oxide Semiconductors or CMOSs. These chips range in size from less than ¼ inch to about 1 inch. Generally, the larger the chip, the greater the resolution of the video image that is produced.

Cameras may contain special highly sensitive chips to produce digital video under different lighting conditions. Day/night vision cameras produce high quality color video with very little available visible light. Night vision infrared cameras produce high quality color video under normal lighting conditions and high quality monochrome or black and white video under infrared conditions.

Night vision infrared cameras contain Light Emitting Diodes or LEDs that project infrared light onto the target area of the camera. This illuminates the target area like a spot light or flood light; however the human eye cannot see this light. On the other hand, the camera can see the infrared illumination and indeed uses it to produce a clear, high quality video,

Day/night vision cameras require at least some sort of visible light; night vision infrared cameras can produce an image in total darkness. However, infrared cameras are limited to how far they can “see” in total darkness based on the LEDs used to illuminate the target area. If your home camera system DVR requires infrared cameras, be sure to check the range of the camera before purchasing to make sure you have one that will fulfill your needs.

Other available options for cameras include audio recording, and Pan-Tilt-Zoom (PTZ) functions. A PTZ camera with motion detection can be programmed to track moving objects.

The DVR of a home camera system DVR is like the hard disk drive on a personal computer. Its main function is to store the digital video files. Raw digital video files are extremely large which makes them difficult to store and handle. The DVR uses a CODEC utility to shrink file size but retain video clarity. DVRs can be purchased in a variety of storage sizes ranging up to several Tera bytes.
