Backup assistance

A device or system of devices (usually a park distance sensor or a back-up camera) designed to aid a drivers control of a vehicle in reverse.
 

Blind spot

Areas around a commercial vehicle that are not visible to the driver either through the windshield, side windows or mirrors. Stickers on the rear of trucks remind other drivers "If you can't see me in my mirrors, I can't see you!" A unfortunate part of rig operation, which is being assisted by rear-view cameras.
 

Exterior camera

A video camera mounted outside a vehicle that relays its signal to a monitor within the cabin.
 

Nightvision

An exterior camera that uses infrared technology to provide added visibility when driving in the dark.
 

Whats the difference between CMOS, CMD & CCD Cameras?

There are two different types of Reverse Cameras which are based primarily on the differences between image sensor technology, those being CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charged Coupled Device).
CCD cameras are the better of the two types as they use digital technology and have higher clarity especially in low light viewing conditions.
CMOS cameras are the cheaper of the two and use analogue technology which is generally of a lower resolution to a CCD camera and is considerably slower to react to low light conditions. CMOS cameras can also come with a CMD sensor which is a high definition sensor that offers better clarity than a standard CMOS camera but about the same night visibility.
Some cameras feature Infra-Red sensors with LED’s fitted to them. IR sensors are mainly found on CMOS cameras as they act in a way that use sensors to draw in light to improve visibility, the downside is that in pure daylight the image can “ash out” due to too much light being drawn in. These cameras are generally used on vehicles that have the camera mounted far away from the reverse lights, including trucks and other large vehicles.

Viewing Angle

There is a noticeable difference in the viewing angle between cameras mainly due to the size of the lens. Generally, cameras use either a 1.7mm or 2.8mm lens for the greatest viewing angle. Some cameras have a larger lens and offer a greater viewing distance but tend to be limited on viewing angle. CMOS cameras can also be prone to a fish-eye appearance due to a high viewing angle but lower sensor technology.

LUX Rating

The LUX rating on cameras refers to its sensitivity to light, the lower the LUX rating the better the camera responds to low lighting conditions. You may see some CMOS/CMD cameras with lower LUX ratings than CCD cameras, this is due to the picture quality of a CCD camera being far superior to the CMOS camera and not needing to be as sensitive to light.

Audio Capability

There are not a lot of cameras on the market that feature audio playback capability. It is mainly found in more robust truck styled cameras. They can be used to assist a driver when getting directions while reversing when there is a great distance between the driver and the rear of the vehicle.

Weather-Proofing

There are 2 different types of weather proof ratings available for reverse cameras, both dust and water. IP67/68 rating refers to a water proof rating, this allows for the camera to be submersible to a pre-determined depth suitable for vehicle applications. All cameras with this water rating exceed the dust rating for vehicle applications. Cameras are NOT able to be cleaned using high pressure water cleaners as this pressure exceeds the IP rating. Being used in salt water will also void warranty.
 

Backup Camera Mirror

A backup camera mirror includes both a backup camera and a monitor for the driver to see a vehicle's rear view. In addition, when the camera is off, the monitor doubles as a regular mirror. When the camera is on, the monitor works like a regular monitor, showing what the camera sees. The back up camera mirror monitor can be mounted on the windshield or dashboard of the vehicle. The back-up camera mirror provides additional safety when driving in reverse or maneuvering your vehicle.

Backup Camera Monitor

A backup camera monitor allows users to watch the rear view of their vehicle through a monitor. The back up camera is mounted on the back of the vehicle and connected to a monitor. The monitor can be mounted on the windshield or dashboard of the vehicle. The back-up camera monitor provides additional safety when driving in reverse or maneuvering a vehicle.

Car Back Up Cameras

Car back up cameras allow users to watch the rear view of their vehicle. The car backup camera is mounted on the back of the vehicle and connected to a monitor that can be mounted on the windshield or dashboard. Car back-up cameras provide additional safety when driving in reverse. Also see, Wireless Backup Cameras.

CCD Backup Camera

CCD backup cameras provide additional safety when driving in reverse. The backup camera is a special type of video camera specifically for the purpose of attaching to a vehicle to aid in backing up. Also known as a rear camera, rear view camera, or reverse camera. CCD backup cameras offer the clearest and highest quality images.

RV Backup System

RV backup systems allow users to watch the rear view of their vehicle. RV back-up systems include a camera, monitor, and all equipment needed to mount and connect these devices. RV back up cameras are mounted on the back of a vehicle and connected to a monitor. The monitor can be mounted on the windshield or dashboard of your vehicle. RV back up systems provide additional safety when driving in reverse or maneuvering your vehicle.

RV Camera

RV cameras allow users to view areas of their RV which may be out of their field of vision, like the rear view. The RV camera is mounted on the back of the vehicle and connected to a monitor. The monitor can be mounted on the windshield or dashboard of the vehicle. The RV camera provides additional safety when driving in reverse or maneuvering an RV. Also see, RV Backup Camera, RV Backup System.

RV Camera System

An RV camera system includes both the backup camera and the monitor. The RV camera system allows the driver of a vehicle to see areas which may be outside of their line of vision, like the rear view. A camera is mounted on the back of the vehicle and connected to a monitor. The monitor can be mounted on the windshield or dashboard of the vehicle. The RV camera system provides additional safety when driving in reverse or maneuvering a vehicle.

Wireless Back Up Camera System

Wireless backup camera systems allow users to watch the rear view of their vehicle wirelessly. The wireless back up camera is mounted on the back of the vehicle and connected to a monitor. The monitor can be mounted on the windshield or dashboard of the vehicle. Wireless back-up camera systems provide additional safety when driving in reverse or maneuvering a vehicle.

Rearview Mirror Carcam Car Digital Video Recorder

 
FPS - Frames Per Second - how many video frames are stored each second - typically around 30 - the higher this value is - the better (smoother) the video will be.

G-Sensor - a sensor inside the cam which detects whether the car has had a bump, braked sharply or cornered "hard".  This sensor often triggers a lock on the current video block preventing loop recording from overwriting it - as it may be required later for viewing.
 
Loop Recording - The method used to re-use memory once a memory card is full.
