If you are just starting to build your commercial semi fleet, then you may decide to start off small with a single used freightliner. This is wise, so you can make some money and invest in some other commercial trucks in your future. If you are serious about expanding, then you need to follow a tight budget and you also need to make sure that your commercial insurance rates are kept as low as possible. This means avoiding accidents as much as you can. Back up accidents are common and can result in serious damage and injuries. You can easily reduce these sorts of issues with a backup camera system. These systems have a wide variety of features you can choose from. Keep reading to learn about a few that you will definitely need. 

Wireless Setup

Many aftermarket or consumer cameras made for easy setup are wireless. This allows you to secure the camera without worrying about installing wires through the cab and trailer of the truck. Wireless cameras are fairly simple devices and work similarly to wireless security cameras. Simple wireless devices allow for digital or analog data transmissions. Since analog devices use a specific and set frequency to transmit data, there is a chance that the system can create some interference issues. If you have other sorts of systems that receive and transmit data, like a CB radio, then it is wise to opt for a digital setup. Digital camera systems cycle through different frequencies as they transmit data. 

WiFi wireless setups are available as well. WiFi enabled devices allow you to setup a variety of cameras, audio equipment, radios, and other devices. All the equipment can receive and transmit data through the router. This allows for consistent communication between devices and the router so you can receive visual and audio information without interference. Also, WiFi systems allow you to set up your own secure network that cannot be accessed by other individuals. 

WiFi devices typically have a wide range of at least 150 feet. This is more than large enough so you can secure the camera on the back of the trailer and fit the router and monitor inside the cab. 

If you decide to go with a more traditional wireless system, then you will need to make sure that the transmitting and receiving distance matches the length of your truck. Otherwise, the rear camera may sit too far away from the receiver. If you choose a device that is specifically made for freightliners, then this should not be a problem.

Advanced Image Capabilities

If you want to back up precisely without an incident, then you should opt for a camera system that is capable of producing crisp and clear images. A camera with a wide angle lens can create a more accurate picture. This sort of device should be paired with a video screen that is large enough for you to see. Screens that are 10 to 12 inches are a good choice. Also, you want the camera to be able to produce HD or high definition images.

When it comes to image quality, you want to make sure that the camera can produce a clear picture in a variety of situations. A waterproof lens is ideal that has an angled protrusion on the top. This protects the lens from rain and snow and keeps it clear from condensation as well. A camera with a light sensor that adjusts images according to light level is a good choice as well.

You will likely be backing up in the dark on occasion, so look for a device that has infrared capabilities. Also, cameras that have their own dedicated light systems can help with producing clear video in the dark.
