How and where to install a tbox?

Generally speaking, there are two types of telematics devices. The most common one for UBI users is the OBD device. The insurance company give the device to its customers, who can plug it into the vehicle’s onboard diagnostics port (OBD-II port). The OBD-II port is usually located under the dashboard. Obviously this kind of device can be plugged-in and used, no special work required for installation. However, it also has obvious shortcomings. It is not fully tightly fitted in the OBD-II port as the vehicle shakes while driving. The data obtained from the OBD device are not very accurate either.

The other solution is to pre-install the telematics box in the car factories, just like Hopechart’s t-box which has been installed by over 40 OEMs of passenger cars, buses and trucks. In this case, the telematics device usually has more interfaces, e.g. CAN port, RS232 and RS485. Through CAN port, the t-box gathers information of vehicle status. Compared to the OBD device, this device is more stable and can record more valuable and useful information.

Telematic Box Review

Advantages The concept of telematics device is more inclined to the improvement of electrical equipment. For example, for traditional cars, the music cannot be connected to the Internet, and its perception of the road conditions and the people and vehicles ahead is relatively blocked. But the telematic can solve these problems, it can achieve more entertaining experience and provide optimal travel routes based on the omni-directional perception through communication technology and the Internet. Telematic focuses on intelligence and enjoyment, for example, it can provide services such as intelligent brake, cruise adaption, intelligent comfort, intelligent interconnection, etc. which is more in line with the taste of consumers. The practicability and maneuverability of the telematic is much higher than that of automatic driving. Disadvantages The larger in amount and more complex the electrical equipment the cars have, the higher the power consumption and the voltage of the vehicle work

FORD'S 'SYNC' DRIVING DATA TO PROVIDE INSURANCE DISCOUNTS

State Farm is expanding its Drive Safe and Save usage-based insurance program to include cars equipped with Ford's Sync  telematics system . Also known as "pay as you go," usage-based insurance programs look at how many miles drivers put on their cars and calculate premiums accordingly. Drivers willing to share how many miles they've traveled could get discounts between 10 and 40 percent in exchange for providing the insurer with a more accurate picture of their  driving patterns . Because Sync's Vehicle Health Report already keeps track of a car's mileage, Sync-equipped vehicles from model years after 2009 are ready to report verified odometer readings to State Farm to calculate possible premium discounts. The insurer also offers Drive Safe and Save to drivers who have installed OnStar's aftermarket FMV mirror in their vehicles. In cars without compatible in-vehicle telematics systems, State Farm requires a driver to plug a data recorder into a car

The Difference Between Mobile DVR And Ordinary Video Hard Disk Video Recorder

As one of the most important functions of vehicle video surveillance equipment, the capability of audio and video codec is one of the key competencies of a vehicle digital video recorder. On this point, there is no essential difference between the vehicle video recorder and the ordinary video recorder. They both choose the mainstream video codec chip and adopt the mainstream codec format to find the maximum harmony between coding efficiency and image definition. At present, most of the decoding methods of ordinary car video recorder adopt the H.264 standard. There is a big difference between the common DVR and the vehicle DVR in the use and acquisition of video. It is also used in truck video system . Common DVR is often used in fixed places and won't be moved casually. It can be displayed locally or through a fixed network (ADSL) access monitoring network. Any observation point in the network can access the DVR host through the network. The vehicle DVR can only monitor the specia
