Pan Tilt Zoom Camera

Written By:
Wednesday, March 30th, 2011

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.

CCTV Housings

Written By:
Monday, February 21st, 2011

Digital video security cameras may need CCTV housings, especially if they will be placed outdoors or in a potentially violent or hazardous environment. Though some cameras are made with protective Closed Circuit Television or CCTV housings, other may require that you install your camera in one before mounting.

Security Camera King offers a wide selection of outdoor cameras and CCTV housings. Normally when a digital video camera is marketed as an “outdoor” camera, it comes from the manufacturer with its own protective housing for use outdoors. However, some outdoor cameras still require CCTV housings under certain conditions.

You may have noticed that certain CCTV housings or outdoor cameras are accompanied by an IP rating that usually looks something like this: IP56. This is actually a rating based on a standard created by the International Electrotechnical Commission or EIC. This rating was designed to provide consumers and manufacturers with a more precise yet standardized method of describing the protection that is offered to an electronic device, in this case of course, the digital video security camera.

The IP rating or sometimes called the IP code stands for International Protection Rating or Ingress Protection Rating. Some times the rating may include a letter after the two digits, but that is seldom seen in reference to CCTV housings or cameras and is really irrelevant for these applications. The two digits following the “IP” however, do have a meaning. Let’s take a closer look.

The first digit of the IP rating represents the degree of protection offered against solid material. This digit’s range is from 0 to 6, with 0 indicating no protection whatsoever and 6 meaning the CCTV housing is absolutely dust tight. For a sense of the rating, a 2 means protection against ingress of objects greater than 12.5 mm such as fingers or other objects.

The second digit of the IP rating represents the degree of protection offered against liquid material. The digit range in this category is from 0 to 8, again with 0 indicating no protection whatsoever from liquids. A rating of 8 however, indicates that the CCTV housing can with stand immersion in water beyond 1 meter in depth. Once again for a sense of the rating, a 4 means protection against splashing water against the housing from any direction shall have no harmful effect on the camera. A good IP rating for a CCTV housing is at least IP55.

Dome and Bullet type digital video security cameras are the most likely models to be manufactured with their own “built-in” or perhaps more accurately, “built-on” CCTV housings. Likewise, these cameras are also most likely to be marketed as “outdoor” or “indoor/outdoor” use cameras.

Security Camera King carries many different types of indoor/outdoor dome cameras including those whose CCTV housings are classified as “vandal proof.” Outdoor dome cameras are often installed in vulnerable locations; that is, since they are the most visible component of a digital video system they are usually installed in areas of high risk (if the system’s layout is designed correctly). These cameras come with a strong metal housing, no visible screws (that could otherwise be maliciously undone), and very strong Lexan domes.

Most of our bullet-shaped cameras come with their own CCTV housings and are marketed as indoor/outdoor types. Bullet cameras are typically used outdoors in areas of low-risk vandalism because the cameras can maliciously be repositioned rather easily.

Box cameras are very popular cameras; however they usually offer no weatherproofing CCTV housings or mounting hardware. If these cameras are purchased with the intent to use them outdoors, you’ll want to purchase you’ll want to purchase our Metal CCTV Security Camera Outdoor Housing with Mount (product # OUTDOOR_HOUSING).

However, if your box camera will be used outdoors in extremely cold climates, you’ll risk fog and condensation forming inside the housing and on the camera lens. In this particular case, you may want to consider purchasing Security Camera King’s Outdoor Camera Housing with Heater and Blower (product# OUTDOOR-HEATED-HOUSING) for just a few dollars more.

Finally, we should mention that we also offer a very large variety of explosion proof CCTV housings and mounting brackets. Explosion proof housings prevent any volatile and potentially flammable vapors from coming in contact with the camera’s electrical components which could cause the gas to ignite. These housings are also made of hardened stainless steel that is able to withstand severe weather conditions. These are excellent for use in any area where extreme security measures are required.

Outdoor Motion Activated Security Camera System

Written By:
Thursday, July 22nd, 2010

An outdoor motion activated security camera system is an ideal choice for perimeter coverage of a home or business. In addition, motion activation is a conservative, economical choice that produces excellent video surveillance and security results.

What exactly is an outdoor motion activated security camera system? The description sounds fairly complicated but in reality the system is relatively simple. Anytime motion is detected, the digital video cameras switch on and begin recording video images. So if no motion is detected, the cameras shut off. This conserves digital video file storage space on a Digital Video Recorder or DVR since the system only records when motion is detected.

Let’s take a closer look at an outdoor motion activated security camera system. These systems are similar to any other digital video security system in that they consist of one to several cameras, a processor/DVR unit, and a monitor. The camera produces an electronic image and sends it along to the processor/DVR. The processor reads the camera data and uses it to create a digital video file. The digital video file may then be viewed on a monitor and/or stored on the DVR for later use.

Most digital video security systems will record constantly, that is 24 hours a day, 7 days a week. However, an outdoor motion activated security camera system only records when motion has been detected. There are several advantages to this type of system.

Many digital video cameras today are wireless; that is they do not have a coaxial cable that transmits the video signal to the DVR. Instead, these cameras have a built in transmitter and antenna that they use to send the signal via radio waves to a corresponding receiver. The receiver then passes the signal electronically to the processor/DVR. However, these wireless cameras still need a wire for a power supply.

To avoid the necessity of a power supply line and transformer, digital video cameras have been manufactured that can utilize rechargeable batteries. A digital video camera with wireless video transmission and rechargeable batteries is truly wireless. This type of camera is incredibly versatile in that it can be mounted almost anywhere without the concern for any type of cabling or wire attachment. However, continuous video capturing can run down the batteries after several hours making replacement with freshly charged batteries necessary. An outdoor motion activated security camera system can greatly extend the run time of rechargeable batteries, because the camera only captures video when motion is detected. Although a very small amount of energy is needed for the motion detector, the largest amount of drain on the battery is during video capture.

Another advantage of an outdoor motion activated security camera system benefits the DVR. A DVR is basically the same thing as the hard disk drive on a personal computer. DVRs come in a wide variety of storage capacities ranging from gigabytes to terabytes in size. Still, digital video files can take up tremendous amounts of storage space, even when COmpression/DECompression utilities are used to make the files smaller in size filling up the storage disk in a short period of time. A motion activated camera only records when motion is detected, which means the DVR is not required to store video files for a continuous 24 hours, unless motion is present for all of that time. Recording video only when activated by motion can greatly reduce the amount of storage capacity needed on the DVR.

How do outdoor motion activated security camera systems detect motion? These cameras are connected to a special sensor called a Passive InfraRed or PIR sensor. When an object passes in front of the sensor, the sensor can detect the change in infrared radiation. A relay connected to the circuit board of the sensor then switches the camera on. Most cameras turn off either after the motion is no longer detected or for a specified time period after the motion is no longer detected.

Some examples of uses for outdoor motion activated security cameras include parking lot monitoring, building entrance and exits, pet monitoring, and perimeter monitoring of homes, yards, buildings, and industrial areas.

An outdoor motion activated security camera system can save time and money. It can enhance the use of wireless, rechargeable battery operated cameras and it can conserve DVR storage space for use when it is most needed.

Residential Security Camera

Written By:
Wednesday, June 9th, 2010

Nothing can provide you with more peace-of-mind about your home than a residential security camera. If you want to be able to “look-in” on your home during the work day, monitor your home from a distant location (for instance, when on travel), or have the ability to record the perimeter as well as the interior of your home, then a residential security camera system is for you. Not only do residential security cameras provide you with the means for real-time security monitoring but thanks current technological advances, they are affordably priced as well.

A typical monitoring system for the home includes from one to many residential security camera(s), a processing unit, a monitor, and a digital video recorder or DVR. There are systems that can use a personal computer in place of the monitor, processor, and DVR and these can save you even more money on the price of the system as a whole.

A residential security camera may be an indoor or an outdoor type camera. Outdoor cameras differ from their counterparts by being enclosed in a case that protects them from the weather and other environmental elements. Often times, outdoor residential security cameras are rated as to the protection they afford from damage by external matter. This rating, called an Ingress Protection code or IP code is based on an International Electrical standard. Most outdoor residential security cameras, unless they will be covered by some other type of covering or protection should be rated IP66 or IP67.

Both ratings indicate that the camera housing protects the inner contents one hundred percent from dust. This is what the first “6” is the code represents. However, and IP66 rating means that in addition, it can withstand powerful jets of water from any direction (the last “6” in the rating). IP67 rated cameras mean that in addition to the protection from dust, they can be submerged in up to one meter of water.

A residential security camera is a digital video Closed Circuit Television (CCTV) camera that can produce high quality color video. In addition to this standard feature, cameras may be able to produce video images in settings where there is very little light or no visible light at all. This is due to the image sensor chips that are used, either a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These integrated circuit chips are able to produce electrical impulses from light that is focused on them from the lens. These electrical impulses are further translated into digital video data.

A day/night vision residential security camera can produce high quality color video in very low light conditions. A night vision infrared (IR) residential security camera can produce high quality color video when there is visible light and high quality black and white or monochrome video under infrared conditions.
A night vision IR residential security camera works by providing its own IR light to illuminate the target area. Generally, these cameras have an array of IR Light Emitting Diodes (LEDs) that surround the camera lens or are next to it that “flood” the target area with IR light. Light that is invisible to the human eye but can be seen by the CCD or CMOS. The LEDs work like an invisible spot light. This particular type of residential security camera works great as a baby monitor or nursery camera. In addition, these cameras can also record audio.

Residential security cameras can be on their own standalone system which includes a DVR to record the video or they can be networked. There are IP ready residential security cameras. IP (Internet Protocol) cameras can be networked using the internet. This means that you can monitor your home cameras any time and any place there is access to the internet. These residential security cameras are particularly useful for people that must travel or as nanny cams that can be monitored from work computers during the workday.

There are several other features or options that are available on residential security cameras as well. Cameras can be purchased with pan, tilt, and zoom options that allow the camera to me moved horizontally or vertically to increase the field of view. In addition, zoom lenses can enlarge subjects using telephoto lenses.

A residential security camera has the versatility to be used anywhere throughout the home. In addition there are several monitoring and recording options available and all can be purchased an installed for an affordable price.
