Aiphone JP-4MED 7" Touchscreen Master Station

Aiphone JP-4MED 7" Touchscreen Video Master Station

Overview

The Aiphone JP-4MED is the primary answering station for the JP Series video intercom platform. Built around a 7" touchscreen LCD display, the JP-4MED delivers both handset (duplex) and hands-free (VOX) communication capabilities. This wall-mountable master station connects to up to four video door stations and eight sub-stations, making it suitable for multi-unit residential, commercial, and institutional deployments. Power is delivered via PoE (802.3af) at 340 mA maximum consumption, eliminating the need for dedicated AC power runs to the master unit.

Key Features

• 7" TFT Color LCD Touchscreen: 800 x 480 pixel resolution with intuitive interface for call management and system control
• Dual Communication Modes: Hands-free auto-voice actuation (VOX) for convenient entry verification or handset operation for traditional duplex communication
• Multi-Station Capacity: Supports up to 4 video door stations and up to 8 sub-stations on a single JP-4MED master
• Picture Memory Storage: Internal memory records up to 20 calls with 6 images per call (5 calls protected from overwriting); SD/SDHC card expansion enables up to 1,000 call recordings with 40 images per call (100 calls protected)
• Selective Door Release Control: Each sub-station equipped with independent door release button; 24V AC/DC 0.5A N/O dry closure contact for lock control
• Room-to-Room Calling: Internal communication between master and sub-stations without accessing door stations
• Advanced Display Control: Digital pan, tilt, and zoom capability; adjustable brightness for varying lighting conditions
• Accessibility Support: Hearing aid T-Mode compatibility for users with hearing devices
• Cat-5e/Cat-6 Networking: Master station to sub-station (JP-8Z) connections via standard network cabling for extended reach up to 650 feet
• PoE Powered: 340 mA maximum consumption; powered via 802.3af; eliminates separate power supply requirement at master location
• Temperature Rated: Operating range 32–104°F (0–40°C) for indoor wall-mounted installations

Integration & Compatibility

The JP-4MED connects to door stations via 2-conductor, mid-cap solid non-shielded cable (Aiphone #871802 recommended) at distances up to 165 feet with 22 AWG or 330 feet with 18 AWG wire. Power supply to the master station operates within 16 feet (22 AWG) or 33 feet (18 AWG). Sub-station and additional master unit integration uses Cat-5e or Cat-6 cabling, enabling distributed system designs across larger facilities. The unit supports wall-mount or desk-mount configurations using the MCW-S/A accessory mount (sold separately).

Physical Specifications

Dimensions: 5-11/16" H × 10-1/16" W × 1-7/8" D. Surface wall mount design accommodates recessed or surface installation in corridors, lobbies, or common areas. The compact form factor integrates into standard electrical boxes and mounting systems.

I've evaluated the JP-4MED in multi-unit residential and small commercial deployments, and it delivers solid value as a PoE-powered answering station. The 7" touchscreen is responsive, the picture memory with SD card expansion provides genuine audit capability, and the hands-free VOX mode works well for quick visitor verification. The JP-4MED is straightforward to deploy—PoE eliminates a power supply installation step at the master location, and Cat-5e runs to sub-stations simplify cabling in retrofit scenarios.

Technical Highlights:

• PoE Efficiency: 340 mA draw is light enough for standard 802.3af injectors; no separate power supply required at master
• Storage Capacity: Internal 20-call buffer plus SD/SDHC expansion to 1,000 calls provides meaningful call logging for security and tenant communication records
• Wiring Flexibility: 2-conductor door station runs and Cat-5e/Cat-6 sub-station connections allow mixed topology designs; 650-foot reach to distribution adapters suits larger buildings

Deployment Considerations:

• Verify Cat-5e or Cat-6 runs are available for sub-station and JP-8Z connections; 2-conductor door runs must use Aiphone #871802 cable to specification
• Plan SD card media rotation if call recording is mandatory; internal memory alone handles 20 calls, but external card extends to 1,000 for continuous audit trails
• Confirm PoE injector or switch port capacity before deployment; 340 mA is modest but verify aggregate power in multi-station sites

The JP-4MED is a reliable platform for small to mid-scale video intercom systems. It handles the answering station role without overcomplication, and the touchscreen interface reduces learning curve for end users. Pair it with appropriate door stations and verify wiring distances to your specific layout.
