Physical Mounting and Environmental Requirements
The Biomax N-G4W terminal features an industrial enclosure measuring 192 x 146 x 95 mm, engineered with rigid construction to withstand demanding heavy industrial environments. When planning wall mounting or turnstile integration, installers must position the unit at an ergonomic height that accommodates its auto-focus distant face recognition system. The onboard optical camera verifies facial templates at distances up to approximately 1.5 meters (4 feet) in ambient conditions ranging from normal room illumination to low light. The 4.3-inch color touch screen (480 x 272 resolution) and 500 DPI optical fingerprint sensor should be mounted within standard reach to facilitate seamless card presenting, pin entry, and touch-screen interaction.
Site engineers must ensure that the installation location maintains an ambient operating temperature between 0°C and 50°C. Although engineered for heavy industrial deployment, the terminal must be shielded from direct precipitation or extreme thermal exposure beyond rated operating limits to safeguard the embedded 1 GHz Linux processing platform and internal optical sensors.
Power Supply and Backup Battery Integration
The Biomax N-G4W operates on a dedicated 12V DC, 2A power feed. Stable electrical delivery is critical to maintaining high-speed identification routines (less than or equal to 1 second) across high-volume transaction points. Installers must route correctly sized low-voltage cabling from a regulated power source to prevent voltage drops over extended distances.
For mission-critical facilities requiring uninterrupted attendance logging and perimeter security during mains failure, the terminal supports power backup battery (they are not included) configurations. The hardware accommodates internal or external backup battery (they are not included) options to ensure continuous power delivery during outages, securing access points and retaining full verification capabilities without system reboot or data disruption.
Door Lock Relays and Access Peripheral Integration
The N-G4W terminal is engineered for full access control automation and physical security management. It includes an onboard relay output for direct integration with electronic door strikes, electromagnetic locks, automatic gates, and perimeter barriers. For egress management and dual-direction door security, the hardware supports various exit peripherals:
- Wiegand Interface: Dedicated Wiegand In and Wiegand Out ports allow the terminal to interface with external slave credential readers or connect directly to third-party building access control panels.
- RS485 Port: Supports external serial exit readers, such as fingerprint or card slave units (like the N-FR12), enabling coordinated ingress and egress logging.
- Egress Controls: Dedicated inputs accommodate mechanical push buttons, contactless no-touch sensors, and wireless remote triggers.
- Serial Integration: An integrated RS232 communication port allows direct connection to thermal receipt or token printers for automated canteen management applications.
Network Infrastructure and Software Deployment
Data synchronization between the terminal and centralized attendance management software (Desktop, Web, or Cloud) is achieved via versatile communication options:
| Interface | Application / Integration Mode | Deployment Purpose |
|---|---|---|
| TCP/IP (RJ45 Ethernet) | Wired local area network (LAN) | High-reliability enterprise networking with real-time Push Data transmission |
| Wi-Fi | Integrated wireless network | Eliminates physical data cabling runs across complex industrial facilities |
| 4G GPRS (Optional) | Cellular data communication | Remote deployment across geographically isolated or off-grid sites |
| USB Host / Slave | Direct flash drive and maintenance link | Offline event log retrieval (up to 200,000 records) and local firmware servicing |
Once network connectivity is established, the N-G4W terminal interfaces with Biomax centralized software or enterprise platforms using available SDK protocols. This infrastructure supports remote user enrollment, central credential push (supporting up to 10,000 face templates, 30,000 fingerprint templates, and 10,000 RFID card credentials), and automated administrative commands such as user expiry and privilege revocation across distributed multi-branch deployments.
