Auto Iris Sensor Senses ambient light and automatically adjusts infra-red strength based on the ambient light. Display Contrast/Contrast Ratio The ratio of the brightest color (white) to the darkest color (black) that the system is capable of producing. A high contrast ratio is a desired aspect of any display. Display Format/Display Aspect Ratio The proportional comparison between a display’s width and height. It is expressed as two numbers separated by a colon. Common aspect ratios for displays are 4:3, 16:9, and 21:9. 16:9 is the international standard format for Full HD.

Universal License Plate Mount Rear View Camera with with Distance Scale Line by Pyle®. This rear-view backup camera that easily mounts to your vehicle's license.

Dot Pitch A dot pitch measures the maximum sharpness of a displayed image. Usually measured in millimeters (mm), a smaller number means a sharper image. Dot Resolution Dots are elements that make up an image. The higher the dot resolution, the higher quality the image. Event Mode Video recording mode which causes footage to be overwrite protected.

Event mode is usually triggered with unusual vehicle movement or sudden impact. FPS Frames per second (FPS) is a measurement of how many unique consecutive images a camera can handle every second. G-Sensor Measures impact or sudden changes in velocities.

Once the G-Sensor is activated, event mode automatically begins. Gamma Correction Corrects colors on your display. H.264 A style of video compression that allows for the greatest video quality with the smallest storage space. IP Rating The IP rating measures protection against solid and liquid objects. The larger the number, the higher the rating. An IP69K rating is the highest rating available, meaning that the system is completely weatherproof. Infra-Red Illuminator Infra-red lights are for night vision.

Infra-reds emit light which the human eye cannot detect but cameras can. This greatly increases visibility in zero or low light conditions without an actual visible light source. Many of our cameras are equipped with infra-red lights. Loop Recording Video recording mode where after video storage is full, the camera will seamlessly loop over and begin recording over the oldest footage. Mobile DVR A recording device used to record video footage. DVR's are useful for fleet managers because they provide footage of accidents and information on vehicle's whereabouts and driving routes.

Motion Detection A feature that automatically records before, during and after an impact while in parking mode. This way the driver has footage from an accident, even when they’re away from their car. Multiplexer The control unit or 'brain' of the system. The multiplexer powers the system, receives all cameras feeds and sends them to the monitor. The multiplexer is connected straight to the fuse box and has a power capacity of 12-24 volts. NTSC National Television System Committee (NTSC) is a video system that transmits 30 frames per second (FPS).

Necessary/Usable Illumination Measures how much ambient light (measure in lux) is needed to view an image. If your system has infra-red illuminators, 0 lux is needed. OEM Original Equipment Manufacturer (OEM) refers to equipment that was installed in a vehicle when it was manufactured. OEM style is an installation with a clean, factory look. PAL Phase Alternation by Line (PAL) is a video system that transmits 25 frames per second (FPS).

Picture Elements Picture elements is another way to write pixel. A pixel is the smallest addressable element in digital imaging. Free Download Software Design Rumah 3d. The more pixels, the higher the quality image.

Power Supply Most of our systems may be powered by 12 or 24 volt batteries, meaning they can be powered by the vehicle battery. DC stands for direct current. S/N Ratio (Signal-to-Noise Ratio) Compares the level of desired signal to the level of background noise. A ratio above 1:1 (greater than 0dB) indicates more signal than noise. Shock A physical or mechanical shock is a sudden acceleration caused by outside factors such as impact.

It is usually measured in G units, which represent multiples of the acceleration of gravity. TFT LCD A high quality monitor used in appliances such as television sets, computer monitors and mobile phones. A TFT LCD monitor improves image qualities including contrast and sharpness.

These displays only use up to half the power of a traditional monitor. TV Lines The maximum number of alternating light and dark vertical lines that can be resolved per picture height. The higher the number, the better the image quality Trigger An automatic action that occurs when a specific operation occurs.

Logilink Ua0072 Webcam Driver. An example is a rear camera view displaying when a car is put into reverse. Vibration A mechanical phenomenon where fluctuations occur about an equilibrium point. It is usually measured in g units, which represent multiples of the acceleration of gravity.

• Infrared LEDs provide good night vision. • Easy license plate installation. • Baked-in marks help with calculating distance. Cons: • Questionable build quality.

• Not waterproof. • Wires not long enough for all applications. Specifications: • Color CMOS camera. • 628x582 (PAL) resolution.

• RCA connectors for video output. The Good There are a few things you should look for in a rear view camera, including a wide viewing angle, high resolution, and night vision that actually works. With its 120-degree viewing angle and 628x582 (PAL) resolution, and seven IR LEDs, Koolertron's license plate backup camera delivers on all of those counts.

The infrared LEDs won't light up the night sky, but they will allow you to safely back up and park after the sun goes down. In addition to the basics, Koolertron's license plate backup camera also includes built-in guidelines, which is another tremendously useful feature. It can be difficult to accurately judge distances when you're dealing with a, which can lead to accidents. Since it uses RCA outputs, you can plug it into your existing or most stand alone LCD screens on the market.

The Bad The biggest issue you're likely to run into with Koolertron's rear view license plate camera is that these units aren't nearly as waterproof as the manufacturer claims. You might luck out and end up with a unit that's completely sealed off, but chances are that you won't. After a hard rain or trip through a car wash, your camera is very likely to have water inside it. They can also end up with condensation on the inside. The picture quality also leaves a little to be desired.

While the resolution is good, the picture can appear washed out, and many green objects can appear reddish. This isn't a huge issue, but it does raise questions about the quality of the color.

Depending on the size and configuration of your vehicle, you might also find that the wiring harness included with the Koolertron rear view license place camera isn't long enough to get the job done. If you drive a big SUV, don't be surprised if you end up having to solder on some extensions. On that note, you should also be aware that the wires themselves are pretty thin. The Bottom Line Koolertron's rear view license plate camera is a great little unit for anyone who is working on a budget. You'll have to be the judge as to whether the positives outweigh the negatives, but if you can pick the unit up for under $20, you'll probably be happy with your purchase. The biggest issue with the camera is the fact that water can penetrate the housing, but that's pretty easy to deal with preemptively.

Before you install the unit, run a bead of silicone around the seam. Just to be safe, you might also want to tag the screw holes, and a thin coating of wax on the lens couldn't hurt either (just don't cake it on so thick that you can't see through it).

That might seem like a lot of work to 'fix' a newly purchased item, but the Koolertron license plate camera is a tremendous value for the money.
