★ Traffic recorder is the instrument to record the image and sound of the vehicle in the road and other relevant information. After the installation of dashcam, it can record the whole process of car driving video images and sound, which can provide evidence for traffic accidents. People who like road trips can also use it to record the process of conquering difficulties and obstacles. Driving while walking video, at the same time time, speed, location are recorded in the video, rather "black box". It can also be used at home as a DV shot fun life, or as a home monitor. In peacetime, parking monitoring can also be done and dashcam can be installed. Video data can not be clipped. If clipped, it will not be able to provide help after the occurrence of liability accidents.

★ The difference between law enforcement recorder and traffic recorder

There are big differences between law enforcement recorders and dashcams. Let's take a look at the differences between the two products:

1 Wearing and mounting methods:

Law enforcement recorder: the structure design conforms to the characteristics of man-machine engineering, suitable for wearing in a certain part of the body, wearing direction can be adjusted. Recording, recording, photography keys can be single hand single key single operation.

Dashcams: Usually mounted on the windshield, most dashcams use suction cups, but some use adhesive.

2 Battery working time:

Law enforcement recorder: Battery working time According to the actual work requirements, the situation is as follows. 1)

Class A: The battery can respectively support the law enforcement recorder continuous recording time 8h, standby state 24h(battery capacity more than 3200mAh);

Class B: The battery can respectively support the law enforcement recorder continuous recording time of 4h, standby state of 12h(battery capacity above 2000mAh);

2) If the battery capacity is insufficient and replaceable batteries are used for power supply, the above requirements must be met when the battery is replaced once.

Tachograph: Generally speaking, the built-in battery capacity is about 350mAh, and the video recording time is about 1.5 hours using the built-in battery, so the tachograph needs to be connected to the car charger to keep the power supply.

3 Data Integrity:

Law enforcement recorder: the stored data should be protected, the stored data can not be deleted or overwritten by the local machine or unauthorized upper computer. The encoded video stream should have anti-tamper and anti-illegal copy authentication measures (such as watermark overlay) to ensure the integrity of the original data.

Dashcam: The recording mode is circular recording.

4 Data Storage:

Law enforcement recorder: can be stored in the data acquisition workstation, storage server, and management server, single police law enforcement video and audio recorder data management system to form a mobile law enforcement information management platform.

Car recorder: Generally connected to the computer with USB data line, in the U disk mode, the recorded files can be copied or cut to play in the computer.

5 Reliability:

Law enforcement recorder: The protection grade of the case of law enforcement recorder meets the requirements of IP68 in GB4200-2008. IP68 conditions are 1 meter deep water and 1 hour soaking time; Bare machine drop height 3000mm, after the test can work normally, stored data will not be lost.

Dashcam: No such requirement.

6 Scalability:

Law enforcement recorder: It has abundant external equipment, which can be connected with external GPS, Beidou module, external camera, external battery, intercom, external 3G/4G transmission terminal, etc. The powerful software management platform can manage massive data more effectively.

Tachograph: Generally, only external GPS module is supported.
