Bus passenger counter system

Modern systems primarily utilize 3D Stereoscopic Vision or Time-of-Flight (ToF) technology to achieve accuracy rates above 98%. These technologies allow the system to distinguish between adults, children, and inanimate objects like luggage. For high-traffic urban buses, ensure the system supports bi-directional counting (simultaneous entry and exit) and performs reliably in low-light or high-contrast environments.

The hardware must support standard communication protocols such as RS485, RS232, or RJ45 (Ethernet). To ensure seamless data synchronization, verify that the device supports SDK/API integration and is compatible with GPS/GPRS modules for real-time location-based passenger data. Look for systems that offer XML or JSON data output formats for easy cloud-server processing.

Since the equipment is installed in a moving vehicle, it must meet EN50155 (Railway/Vehicle Electronics) or ISO 16750 standards for vibration and shock resistance. Additionally, ensure the sensors have an IP67 waterproof and dustproof rating to withstand cleaning and humidity. For the European market, E-mark (ECE R10) certification is mandatory to ensure electromagnetic compatibility.

Most sensors have an optimal installation height between 2.0m to 2.5m. Buyers should request the Field of View (FoV) specifications to ensure the sensor covers the entire door width without blind spots. Suppliers on Made-in-China.com often provide customized mounting brackets to adjust the tilt angle, which is crucial for buses with slanted entryways.

Always request a sample unit for bench testing before placing a bulk order. Verify the voltage range (typically 8V-36V DC) to ensure it matches the bus electrical system. Use the 'Audit Reports' feature on Made-in-China.com to confirm the supplier has a dedicated R&D team capable of providing remote technical debugging support.

Focus on Total Cost of Ownership (TCO) rather than just the unit price. Negotiate for extended warranties (2-3 years) and the inclusion of configuration software at no extra cost. For orders exceeding 500 units, aim for a 15-20% volume discount and request OEM branding (logo silk-screening) to be included in the package.

Ensure the supplier uses anti-static packaging and reinforced shock-absorbent foam. For international trade, FOB (Free On Board) is recommended for larger volumes to maintain control over freight costs. Ensure the HS Code (typically 8529.90 or 9029.10) is correctly declared to avoid customs delays or incorrect tariff applications in your destination country.

Utilize Secured Trading Services provided by Made-in-China.com to ensure payment is only released after the goods pass a third-party pre-shipment inspection. This inspection should specifically verify the MAC addresses and firmware versions of the sensors to ensure they match the agreed-upon specifications.
