P400M9-DMR

The P400M9-DMR is a hybrid device that combines a rugged Android smartphone with a professional DMR Walkie-Talkie. Its biggest advantage is "Multi-mode Communication": it supports PoC (Push-to-Talk over Cellular) for nationwide communication via 4G/LTE, and DMR (Digital Mobile Radio) for off-grid, direct device-to-device voice communication when cellular signals are unavailable.

Yes, the DMR function works completely without a SIM card or Wi-Fi. Because it features a built-in UHF (400-480 MHz) or VHF (136-174 MHz) radio transceiver, users can communicate directly with other standard Walkie-Talkies within range (typically 2-5 km depending on terrain), making it critical for basement, tunnel, or remote area operations.

It runs on Android 11 (or newer). Unlike traditional "dumb" radios, the P400M9-DMR allows users to run modern enterprise apps, check emails, view maps, and access web-based databases, all while maintaining a voice channel open for team coordination.

The device features a compact 4.0-inch display (800 x 480 resolution). This size is intentional for "Tactical Portability". It is small enough to be operated with one hand or clipped securely to a vest/uniform without weighing the user down, yet large enough to view maps and read text clearly thanks to optical bonding technology.

Yes, it is compatible with standard DMR Tier I and Tier II radios. It supports both Analog and Digital modes. IT managers can program the device's frequencies to match the existing fleet of handheld radios (e.g., Motorola, Hytera) used by security or construction teams, ensuring seamless integration.

Yes, it features a large, textured PTT (Push-to-Talk) button. Located on the side of the device, this tactile button enables instant voice transmission without waking up the screen or unlocking the app. There is also an Emergency (SOS) button and a channel selection knob for quick adjustments without looking.

It is built to IP65 and MIL-STD-810H standards. The device is fully protected against dust ingress and low-pressure water jets (rainproof). It is also tested to withstand drops from 4 feet (1.2 meters), ensuring it survives the rough handling typical of police, security, and industrial work.

Yes, it supports an optional integrated 1D/2D Barcode Reader. This turns the radio into a powerful data collection tool. Security guards can scan checkpoints (NFC or Barcode) to log patrols, while warehouse staff can scan inventory, all while staying connected via the radio headset.

The device comes with a 2700mAh (or higher) user-replaceable battery. While radio transmission consumes power, the efficient ARM Cortex processor ensures it lasts through a standard shift. The removable battery design allows heavy users to swap in a fresh battery in seconds, which is essential for 24/7 mission-critical operations.

Yes, it features a professional multi-pin audio connector. Aside from the loud front-facing speaker, it includes a specific Kenwood-style or proprietary connector (depending on SKU) for secure attachment of tactical headsets, surveillance earpieces, or remote speaker microphones (RSM).
