Motorola DP1400 — 32 Channels, 98 Phon, IP54 at 19 Hours
The industry’s most deployed analog-to-digital migration radio. Dual-mode analog/digital operation with auto-detection lets a fleet be upgraded in phases instead of replaced at once, 98 phon audio carries over industrial noise, and 32 channels with 5W UHF/VHF TDMA dual-slot cover straightforward talkgroup layouts. IP54 sealing is rated for thermal shock and humidity rather than immersion. A 1,500mAh battery delivers 19 hours at 310g in a no-display body that stays operable with gloves. DMR Tier II, GPS-ready, with Transmit Interrupt supervisor priority override. Its real leverage is ecosystem continuity — every accessory, repeater and programming cable is shared across the DP1000/DP2000/DP4000 families.
Motorola DP4401e — 99 Channels, IP67, 28-Hour IMPRES 2
The next rung in the same family: 99 channels across multiple zones — 3.1 times the DP1400 codeplug — with a color display for call management instead of blind channel stepping. IMPRES 2 battery management lifts runtime to 28 hours, a 47 percent gain on the DP1400’s 19. Ingress protection steps from IP54 to IP67 submersible, and GPS plus AES-256 encryption with Enhanced Privacy options add location tracking and a security tier the entry model does not carry. Runs MOTOTRBO DMR on licensed or license-free spectrum with Capacity Max and Tier III options for multi-site growth. The upgrade to buy when a DP1400 fleet outgrows its codeplug, its shift length or its dry-environment assumption.
| Specification | Motorola DP1400 | Motorola DP4401e |
|---|---|---|
| Tier / Positioning | Entry analog-to-digital migration bridge | Mid-range full-featured MOTOTRBO |
| Channel Capacity | 32 channels | 99 channels across multiple zones (3.1x) |
| Battery / Runtime | 1,500mAh / 19 hours | IMPRES 2 battery management / 28 hours (+47%) |
| Ingress Protection | IP54 (thermal shock and humidity tested) | IP67 submersible |
| Display / Interface | No-display form factor at 310g, gloved-hand operable | Color display for call management |
| Location & Security | GPS-ready; no encryption tier | GPS + AES-256 with Enhanced Privacy options |
| Trunking / Networking | DMR Tier II conventional | DMR Tier II with Capacity Max / Tier III options |
| Ecosystem | Shared MOTOTRBO accessories, repeaters and programming cables | Same family ecosystem — zero-migration upgrade path |
The Entry-to-Mid Fork
Stay on the DP1400 while the requirement is cheap, proven, phased analog-to-digital migration: 32 channels cover flat talkgroup layouts, 19 hours covers a single shift, 98 phon covers noisy sites, and the no-display 310g body is the most glove-friendly option in the tier. Every unit stays inside the same MOTOTRBO accessory and programming ecosystem, so nothing is orphaned. Step to the DP4401e when any one of four constraints breaks: the codeplug outgrows 32 channels (99 across multiple zones is 3.1x), the shift outruns 19 hours (IMPRES 2 delivers 28, up 47 percent), the site gets wet (IP54 becomes IP67 submersible), or the audit requires encryption and location (AES-256 with Enhanced Privacy plus GPS). The economics are blunt — DP1400 is bought per unit, DP4401e is bought per constraint removed. For mixed fleets, run DP1400 on the floor and DP4401e for supervisors and multi-zone sites; the shared family ecosystem means the two tiers program, charge and service from one toolchain.
