Motorola MTP3150 — Class 3L 1.8W TETRA with NFC Patrol Checkpoint
TETRA patrol radio engineered for presence verification: Class 3L 1.8W power-optimized RF output for dense urban and campus coverage, plus integrated NFC for patrol checkpoint tap-and-go logging — guards tap the radio at each patrol point and the supervisor receives a verified route record with zero paperwork. The power tier is the design decision: 1.8W keeps battery drain minimal in coverage-dense environments where higher power adds nothing, while the NFC workflow replaces manual sign-in sheets for site security, campus patrol, and facility rounds.
Hytera HP705 — 256-Channel DMR with GPS and 22-Hour Battery
DMR field-team radio built for wide-area visibility: 256-channel capacity across multiple zones, integrated GPS so dispatchers see every team member on the map, IP67 protection, and a 22-hour battery carrying full-shift operations. DMR Tier II dual-slot TDMA doubles capacity on one frequency pair. The protocol decision: TETRA infrastructure delivers trunking and encryption as native features, while DMR delivers similar group-call capability at lower infrastructure cost — the HP705's 22-hour envelope and GPS visibility suit field teams whose priority is coverage radius and fleet tracking rather than patrol-log verification.
