Wow, did I ever get an education when I wanted to purchase a hunting game camera for my significant other. Short forms with the capital letter combination, What did they all mean? After countless hours of looking up the meaning to each combination I thought I would share my now wisdom with those of you that might be up the same tree as I was.
First of all, What is a hunting game camera?
A hunting game camera is a unit of molded hard plastic that is an excellent piece of equipment which is used by hunters to set-up in designated areas usually attached to trees to capture images of their would be prize hunted. (deer, bucks, does, whit-tail deer). The camera has a lens and features that can be manually set for daytime and night-time use being left unattended at destinations a couple of weeks at a time. It is the replacement of your own watchful eyes and less disturbing than your own body movement while perched in trees and sitting in camouflage huts. It does not leave the human scent readily active to spook the animals.
CMOS: Complimentary Metal Oxide Semiconductor. This is the most widely used integrated circuit design. It is found in almost every electronic product from hand-held devices to mainframes. The CMOS Image Sensor enables the integration of all required camera circuits onto the same chip.
CCD: Charge-Coupled Device. An electronic memory that records the intensity of light as a variable charge. Widely used in still cameras, camcorders, and scanners to capture images. CCDs are analog devices. Their charge equate to shades of light for monochrome images or shades of red, green and blue when used with color filters. Devices may use three CCDs one each of red, green, and blue colors. The "coupled" in the name is because the CCD is comprised of an array of imaging pixels and matching array of storage pixels that are coupled together.
SD Card: Secure Digital Memory Card. A flash memory card that provides storage for digital cameras, cellphones and PDAs. They are available in a great number of size capacities. 1GB - 64GB.
MMC: Multi Media Card. A flash memory card that provides storage for cellphones, PDAs and other hand-held devices. The card uses flash memory for read/write applications and are noted for their fast transfer rate.
MP: Mega Pixel. Mega pixel is one million pixels (dots). Referring to the resolution of a digital imaging device (monitor, scanner, still camera, video camera etc). An example a 5MP still camera captures a picture composed of 5,038,848 pixels, each pixel containing a red, green, and blue color dot. Such an image would have 2592 x 1944 resolution: 2,592 pixels (dots) across and 1,944 pixels (dots) down. Mega = a-lot Pixel= pix-picture el-element.
GB: Giga Byte. A very large common unit of storage from desk-top computer to mainframe. Giga is a prefix attached to common non-computer words that mean a very large size or quantity. Byte: is the first and last letter of 2 combined words which are Binary Table.
Mega > means million and Giga > means billion.
Resolution: The resolution on the game camera means the size of the digital images produced which is usually expressed as mega-pixels. Game cameras start at a 2 MP and have now with improved technology 12 MP are available. So depending on the size of the images you want to show off, the larger the mega-pixel the larger the image. You also have game cameras that incorporate different resolutions in the one unit enabling you to choose what mega-pixel you want to use. Example: An 8 MP that allow you to use 3 MP, 5 MP or the 8 MP.
JPG: (JPeg): Joint Photographic Experts Group. An ISO/ITU standard for compressing still images. The JPeg format is very popular due to its variable compression range. JPegs are saved on a sliding resolution scale based on quality desired. **High quality - for photo printing. ** Medium quality - for the web. ** Low quality - for attaching e-mails.
TFT screen: Thin Film Transistor. A transistor that is deposited onto a substate in thin layers. TFT transistors are commonly used in active matrix LCD screens, which are sometimes called TFT screens.
LCD screen: Liquid Crystal Display. Sandwiched between polarizing filters and glass panels, liquid crystals are rod-shaped molecules that flow like liquid and bend light like crystal. The orientation of the filters and panels determine how light passes through the crystals. Major categories are Passive and Active. Passive displays are widely used for fixed purpose, mostly monochrome read-outs on printers, appliances, and industrial products. In contrast, active displays, which are mostly color, are the graphic-based screens used in TVs, computers and numerous other devices.
LED: Light Emitting Diode. A display and lighting technology used in almost every electrical and electronic product on the market, from a tiny on/off light to digital read-outs, flash-lights, traffic lights etc. They last for decades and are virtually indestructible.
IRED: InfraRed Emitting Diode. A LED that emits infrared light. IREDS are widely used in audio and video controls as well as IrDA ports on the computers and peripherals.
PIR sensor: Passive Infrared Sensor. A device used to detect motion by receiving infrared radiation. Example: When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR sensors are used for applications such as automatically turning on lights when someone enters a room or causing a video camera to begin operating.
Trigger Time: Is the time elapsed from one image to the next image. Depending on the make and model of the game camera trigger times can be from a fraction of a second up to 10 seconds.
OS: Operating System. The operating system set the standards for all application programs that run in the computer. 98SE: is Windows 98 standard edition. 2000XP: is Windows 2000 Extreme programming, you can have XP - Home edition for the consumer or XP-Professional Office edition. ME: is Microsoft Exchange - exchange server supports web-based access and smart phone access. Also popular e-mail messaging system.
USB cable: Universal Serial Bus. The most widely used hardware interface for attaching peripherals to a computer. One use (among many) of the USB cable is to transfer (down-load) data from one device to the computer.
AVI cable: Audio Video Interleave. A container video format that specifies certain structure how the audio and video streams should be stored with-in the file.
NTSC: National TV Standards Committee. This is encoded in the YUV color space, which provides a mathematical equivalent of red, green, and blue. It also includes an audio FM frequency and an MTS signal for stero. Also a lot of history and specifications go with NTSC, TV jargon.
PAL: Programmable Array Logic. PALs are defined by their number of inputs and out-puts. Has to do with voltage, fuses, circuits and out-put lines.
I certainly hope this has helped any-one with inquiring minds and enhances your wisdom the next time you look at, or shop for a game camera.
