About CETRA

cetra-logo-horizontal
CETRA stands for Citizen Entry Type Record Application. Prime Servant, Inc., the company running CETRA, is an information processing service and video platform business using artificial intelligence technology. It operates in Tokyo, Japan. CETRA is a video platform project that redefines dashcams as moving CCTV (closed-circuit television, i.e. security cameras) and uses them for local crime prevention, criminal investigation, and preparation for natural disasters.

The concept of CETRA

Safer local community created by cooperation between government and citizens.

What problems did CETRA need to solve?

In a country where citizens are concerned by privacy issues caused by static surveillance cameras, CETRA needed a solution to search/request only the required range of images from participants’ dashcam running in the vicinity of an incident and provide them to relevant agencies such as police or fire departments.

All this needed to be done while respecting privacy and in a cost-effective way.

CETRA aims to reduce reliance on costly surveilance camera systems and empower drivers to participate in making their neighborhoods safer and more respectful of individuals’ privacy. 

Why did Prime Servant choose BlackVue?

  • None of the local dashcam companies (in Japan) were able to meet CETRA’s requirements.
  • Prior to integrating with BlackVue, CETRA started the service with a dashcam application in smartphones. However, it faced limitations.
  • Later, the problem was solved by linking the BlackVue Cloud server with the CETRA server.

How did CETRA integrate with BlackVue?

 

  • CETRA connects to BlackVue Cloud at the server level, using the BlackVue Cloud API.

For example, if the police request the CETRA platform to search videos based on specific time and location criteria, CETRA forwards the request to the BlackVue Cloud server.

After it receives the request, BlackVue Cloud searches if any CETRA participant’s dashcam recorded video that meets the conditions (The GPS Log data of the dashcam is being collected 24/7). If there is any, the dashcam user is prompted to upload the video to BlackVue Cloud. As soon as the user uploads the video, BlackVue Cloud transfers the video to the CETRA server for processing and analysis.

After an incident is confirmed, a CETRA-authorized officer logs into the CETRA server and enters a search perimeter around the location of the incident, as well as a time interval. The request is relayed to participants’ dashcams via the BlackVue Cloud server.

After the dashcam receives the signal, the BlackVue dashcam searches for the footage. If there is footage recorded when the accident happened, it will identify relevant footage and prompt the user to upload it to BlackVue Cloud for CETRA purpose.

The footage uploaded from each dashcam is forwarded to the CETRA server, where it is analyzed and used for criminal investigation, identifying the cause of the accident, and preparing for natural disasters.
