How to Clean Digital Camera Lenses:
- Sharp pictures from a digital camera depend on a spotless lens. All digital camera lenses are made of precision-ground glass with a protective coating over the surface. But that coating can still get dirty, and it will not stop grains of sand or grit from scratching the glass unless you take care to clean the lens properly
- Inspect the lens surface for fingerprints, grime, dirt and grit or sand. Turning the lens at an angle to reflect the light will help you spot grime that might not immediately be visible
- 2Blow any particles, such as sand or grit, gently off the lens with the compressed air before attempting to wipe it. Rubbing a lens with grit is an invitation to disaster, as the lens is likely to become scratched and ruined
- 3Pour a small amount of lens-cleaning solution on a lens paper or clean, lint-free cloth, and gently wipe the surface of the lens in a circular motion
- 4Allow the cleaning solution to evaporate, rather than attempting to dry the lens by continuing to wipe it. This minimizes the risk of scratching
How to Choose the Right Camera Lens:
- Choose a subject to photograph
- Opt for a telephoto lens (a lens with a focal length greater than 55 mm) to bring your subject closer.
- Select a wide-angle lens (a lens with a focal length of less than 40 mm) to broaden the scope of your photograph
- Use a regular lens (a lens with a focal length of 40 mm to 55 mm) for most situations, because it offers the maximum aperture range, which allows you to photograph under a wider variety of lighting conditions
- Go for a zoom lens (a lens without a set focal length) to reduce expense and increase flexibility because it lets you shoot across a wide range of focal lengths from wide-angle to telephoto using one lens
How Does a Rear-View Camera Work in a Car?
- Rear-View Camera Versus Rear-View Mirror
Rear-View Camera Display Monitor on sun visorRear-view mirrors allow drivers to view a large portion of the area behind their vehicles. However, trunks and rear decks often limit the view of the road as much as ten to 15 feet behind the vehicle. Rear-view cameras, also known as "reversing cameras" or "backup cameras," resolve this problem. These cameras enable drivers to see objects and people directly behind their vehicles.
- How Does a Rear-View Camera Work?
Rear-View Camera Display Monitor on dash boardThe structure of a rear-view camera is different from other cameras. The reflection of a rear-view camera is horizontally flipped so that it produces a mirrored image. This is essential because the driver and the rear-view camera are in opposite positions. The mirrored image is also necessary because it causes the direction of the display to be constant with the mirrors mounted on the motor vehicle. The rear-view camera display is usually wired to automatically sense when the transmission is set in reverse, and it shows the rear view while the car is in reverse. The other items in the rear of the vehicle are also shown at all times. The rear-view camera usually consists of a wide-angle or fish-eye lens. Although the lens doesn't allow the camera to view distant objects, it does permit the camera to view a continuous horizontal view from one corner, behind the car, to another. Rear-view cameras are also generally mounted at a downward angle. This allows the camera to show potential barriers on the ground in addition to the location and position of walls and docks that may be looming around the corner.
- How is a Rear-View Camera System Installed in a Car?
Plate-mounted rear-view cameraRear-view camera systems are generally mounted to the lower outside areas of the vehicle or to the vehicle's bumper. With the camera mounted in these locations, it allows greater visibility. The rear-view camera display is often mounted inside the vehicle on either the sun visor or within the dash board area. Rear-view camera systems can be purchased as either wireless or wired back-up systems. In wired systems, the camera is linked to the display monitor via a long cable wire. In wireless systems, images are transformed to radio signals, transmitted and then converted from a radio signal back to a video image once it reaches the receiver and monitor.
Wired systems such as portable rear-view camera systems or semi-permanent, all-in-one back up camera systems, for example, are generally sold to consumers who have smaller vehicles. These portable units include small display screens. The screen is easily attached to the sun visor and has a lengthy wire that connects to the camera.
Because signals have to be converted via the airways with wireless systems, they sometimes receive interference from other wireless components as well as poor signal reception. As a result, many believe that much better quality is received with wired systems.
How to Install a Rear-View Camera in Your Car?
- Disconnect the battery cables from the battery. Check the vehicle's repair manual to find out what size wrench to use. Leave the disconnected cables a safe distance from the battery posts.
- Decide where you want to install the rear-view camera. Most people put them in the plastic bumper so they don't have to drill into the car's sheet metal.
- Drill a hole for the camera. Check the installation instructions to see what size drill bit to use. Don't make the hole too large or the camera will fall out.
- Place the camera in the hole using the rubber grommet supplied with the camera. Make sure the camera and grommet are tight.
- Attach the camera's power wire to the backup-light power wire on your car. You'll have to splice the wires together. Use wire cutters to cut the wires, leaving enough excess wire to reconnect. Strip the ends of the wire to expose the bare wire using wire strippers. Splice the wires together using a two-into-one connector. This will give the rear-view camera power when you put the car in reverse.
- Route the camera's output wire to the rear-view monitor and connect the wire to the monitor's input. For installation of the monitor, see the monitor's installation instructions.
- Reconnect the battery, start the car and put the car in reverse. The rear-view monitor should turn on and give you a view of what's behind you.
Tips & Warnings:
- Don't rely solely on the rear-view camera when backing up. Use it as a supplementary aid
- You must have the rear-view monitor set up and installed correctly to receive the video signal from the rear-view camera
- Don't install the camera (or any electrical device) with the battery connected, or you'll risk a severe electric shock
