Using Body Worn Camera to assist in contact tracing for novel coronavirus (COVID-19)

BWC058-4G – OMG Mini Body Worn Camera with Facial Recognition 4G

Using Body Worn Camera to assist in contact tracing for novel coronavirus (COVID-19)

Leverage body worn camera video footage to help support and supplement current contact tracing efforts in the nation-state in an effort to reduce the spread of COVID-19.

How it Works

Currently, contact tracing relies on the recall and memory of interviewees. There were however, instances when interviewees could not remember all their contacts, or did not have information on whom they had been in contact with. Video footage that is recording by the body Worn Camera can use to perform contact tracing; identification of persons who may have come into contact with an infected person (“contacts”) and subsequent collection of further information about these contacts. This facilitates the contact tracing process, and enables contact tracers to inform users who are close contacts of COVID-19 cases more quickly. This enables users to take the necessary action sooner, such as monitoring his own health closely for signs of flu-like symptoms.

The goals of contact tracing are:

  • To reduce spread of an infection & interrupt ongoing transmission
  • To learn about the epidemiology of a disease in a particular population
  • To alert contacts to the possibility of infection and offer preventive counseling or prophylactic care
  • To offer diagnosis, counseling & treatment to already infected individuals
  • If the infection is treatable, to help prevent reinfection of the originally infected patient

Steps in contact tracing using body Worn Camera

Contact tracing generally involves the following steps:

  • An individual is identified as having a communicable disease (often called the index case). This case may be reported to public health or managed by the primary health care provider.
  • The index case is interviewed to learn about their movements, whom they have been in close contact with or who their sexual partners have been.
  • Depending on the disease and the context of the infection, family members, health care providers, and anyone else who may have knowledge of the case’s contacts may also be interviewed.
  • Retrieve video footage of index case from Body Worn Camera – Digital Evidence Management System base on Period (Date & Time) .
  • Retrieve all Photo Registered by Body Worn Camera – Facial Recognition Function.
  • Once contacts are identified, public health workers contact them to offer counseling, screening, prophylaxis, and/or treatment.
  • Contacts may be isolated (e.g. required to remain at home) or excluded (e.g. prohibited from attending a particular location, like a school) if deemed necessary for disease control.
  • If contacts are not individually identifiable (e.g. members of the public who attended the same location), broader communications may be issued, like media advisories.
  • Although contact tracing can be enhanced by letting patients provide information, medication, and referrals to their contacts, evidence demonstrates that direct public health involvement in notification is most effective.

Product Features

  • Low power, long battery life

  1. 1080P HD video recording is about 0.8 watts, which is half of the power consumption of the Ambarella A7 solution, and 1/4 of the MTK solution.
  2. 4200mAh battery can record up to 14 hours with h.265 1080p video only.
  3. PWM charging technology can provide 2 Amp fast charging and avoid overheat which extends battery life significantly.
  • Low bit-rate, high definition.

  1. Our body camera with 3D motion compensated noise reduction (MCTF) and H.265 (HEVC) video encoding can provide 50% off bitrate to the competitors who use H.264 (AVC) only. And Smart HEVC technology can achieve very low bitrate up 80% off with relative static scene. 32GB can save upto 25 Hrs of video footage.
  2. 1080P (1440P Max) high definition remote live video can present much more details than 720p video.
  • Quick connecting, fast charging

  1. Boot up in 6s.
  2. 3.5 hours fast charging with charging cradle (4200mAh battery, 2A power adaptor);
  • Better User Experience

  1. Small size (83.2*54.8*29.8mm), light weight (145g).
  2. IP68 waterproof level;
  3. Qualified waterproof speaker provides continuous good sound quality even it has been dipped into water.
  4. Better night vision effect is achieved by scattering glass to avoid flash light effect;
  5. High video resolution up to 1440P (2560×1440) with affordable bitrate;
  6. Customized logo can be burned into the record video;
  7. Dewarp function to correct image distortion;
  8. Wide working temperature from -30 to 60 degrees Celsius;
  9. 8 hours recording time can be reached at -30 degrees Celsius with normal battery.
  • AI (Optional)

  1. 4 core ARM Cortex A53 processors help implementing AI functions, for example, face recognition. It can support deep learning, faster and more accurate face recognition, and the face number can be up to 10,000 with local face database.
  2. It can co-operate with cloud server for face recognition and comparison (under developing).
