Indoor parking guidance camera Milesight PM3322-E Ethernet RS-485 for vehicle detection and monitoring

Milesight PM3322-E is an indoor parking guidance camera with Ethernet and RS-485 connectivity designed for vehicle detection and monitoring in parking facilities. The camera combines sensor-based detection and live image output to feed parking guidance systems and surveillance networks, delivering real-time presence information and visual confirmation for indoor garages, multi-level car parks and covered parking bays where centralized monitoring and system integration are required.

Advantages

The camera offers hybrid connectivity with Ethernet for network integration and RS-485 for legacy control systems, enabling flexible installation options. Built for indoor environments, it provides continuous vehicle detection and visual monitoring with low-maintenance operation. The device is compatible with common parking guidance system architectures and supports real-time data exchange to reduce manual checks and improve space utilization tracking.

Suitable for

• Indoor garages and underground parking facilities
• Multi-level car parks requiring central monitoring
• Parking guidance systems that need vehicle presence data and visual feeds
• Integration with building management or security control systems using Ethernet or RS-485

Key specifications

• Indoor installation design optimized for covered parking areas
• Ethernet network interface for IP integration and live video/data streaming
• RS-485 serial connection for control-system communication
• Vehicle detection capability providing presence/absence status in real time
• Visual monitoring output for verification and surveillance purposes
• Compact form factor suitable for mounting in parking bays and ceiling locations

How to use

Install the camera at a location with clear line of sight to the parking bays to be monitored and follow standard mounting and cabling practices for indoor devices. Connect the Ethernet port to the local network for IP-based data and video transmission; use the RS-485 terminal to link the camera with existing parking control panels or building management systems when serial communication is required. Configure detection zones and integration parameters within the parking guidance system or the device’s management interface to ensure accurate presence reporting and correct data routing to the central monitoring station.

Recommendations

Place the camera to minimize occlusions and strong backlight, maintain regular cleaning of the lens for reliable detection, and verify network and RS-485 settings after installation. For optimal performance, align detection zones with actual parking bay dimensions and test integration with the parking guidance controller before full system deployment.
