What Causes a Dash Cam to Flash?

A flashing red light on a dash cam indicates that it is in normal recording mode, which is a normal phenomenon. During driving, the dash cam usually activates automatically when it detects vehicles or pedestrians within the lens range, triggering the recording function. A dash cam is a device that records images, sounds, and other relevant information during vehicle travel. After installation, it can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. It can also serve as a parking monitor. The video footage from a dash cam should not be edited, as tampering with the footage may render it useless in determining liability during accidents. Additionally, it helps prevent unavoidable fraudulent claims in today's society. A dash cam can record continuously while driving, capturing details such as time, speed, and location. It can also be used at home as a DV camera to record life's moments or as a home surveillance device.

What are the new regulations for vehicle scrappage?

The new regulations stipulate that registered motor vehicles that fail to obtain the motor vehicle inspection qualification mark for three consecutive inspection cycles after the expiration of the inspection validity period will be forcibly scrapped. The vehicle scrappage process is as follows: First, the car owner applying for scrappage and renewal must fill out the "Application Form for Motor Vehicle Modification, Transfer, Modification, Suspension, and Scrappage Approval" and affix the owner's seal. Then, wait for the registration acceptance office to issue the "Vehicle Scrappage Notice" for vehicles that have reached the scrappage age. For motor vehicles that have not reached the scrappage age, after being verified by the motor vehicle inspection office and meeting the scrappage standards, the "Vehicle Scrappage Notice" will be issued. Next, the owner should choose a qualified recycling company to dismantle the vehicle with the "Notice". After verifying the "Notice", the recycling company will dismantle the vehicle and take photos. The requirements are that the engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. Finally, the owner should submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection office for verification and signature. After the license plates and certificates are reclaimed and the approval is reported according to regulations, the private vehicle scrappage registration can be completed.

Tensioner damage: Damage to the automatic tensioner or manual fixed tensioner can prevent the belt from maintaining the necessary tension for proper operation.
