Mobile phone and seatbelt detection cameras will detect a seatbelt offence for people who:

1. Are not wearing their seatbelts while driving or riding in a vehicle. These cameras are designed to identify individuals who are not properly secured in their seats.

2. Are using their mobile phones while driving. This includes holding the phone in their hand, texting, or making a call without a hands-free device.

These cameras use advanced imaging technology to detect these offences even at high speeds. They are typically installed on roadsides or overhead on highways.

Please note that laws and regulations regarding seatbelt use and mobile phone use while driving may vary by location. Always follow local laws to ensure your safety and avoid penalties.
