Translation: The on-site law enforcement recorder is capable of video evidence collection and is widely used in the public security system. The success of cloning the on-site law enforcement recorder by Shenzhen EastDAO Technology in the fields of PCB copying, PCB cloning, reverse engineering, chip decryption, sample clone, sample production, and sample debugging serves as a model example.

EastDAO Technology first conducted a comprehensive evaluation based on the sample provided by the customer, including cost estimation of PCBA production and material calculation, and then provided a quotation to the customer. Subsequently, we assisted the customer in cracking the specialized encryption IC on the mainboard of the on-site law enforcement recorder. Due to our extensive experience in this area, we quickly identified and successfully decrypted the encryption IC, followed by the completion of PCB cloning, sample production, and debugging.

We provided the customer with full-service support throughout the project (on-site law enforcement recorder), from evaluation to sample delivery. The customer was highly satisfied with our attitude and quality. Besides offering clone and imitation of this product series and secondary development, we also provide various vertical services, such as PCB design, PCB cloning, chip decryption, sample production, sample debugging, and SMT processing, ultimately helping to maximize customer benefits.
