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.

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. 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. 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.
