1. Earthquake resistance: Since the bus is in a bumpy state almost every day, the seismic requirements of the equipment are extremely strict, which is the main reason for the high damage rate of the ordinary hard disk type.
2, waterproof: especially for the application of public transport, passenger vehicles, often in the cleaning of the car floor, it is inevitable that water will be washed onto the equipment, so the equipment must be waterproof, water resistance should not be lower than four.
3, dust prevention: dust is another major "killer" of electronic equipment, especially non-air-conditioned vehicles, dust, dustproof should not be less than five.
4. Loss prevention: Since the monitoring system can monitor the behavior of the passengers in the vehicle during the use process, some monitored personnel do not want to be monitored, and will try to destroy the monitoring equipment, causing the illusion of damage during the use of the equipment, then monitoring The equipment does not work, so the vehicle monitoring must have a certain degree of damage prevention.
5, wide voltage: vehicle monitoring equipment needs to have good wide voltage support, especially in the vehicle ignition, acceleration, braking, battery output voltage fluctuations.
