Pliant Technologies PMC-2400M

The PMC-2400M is the standard single-channel beltpack in Pliant's MicroCom 2.4 GHz wireless intercom line, an economical way to put a small crew on full-duplex comms without a base station. One channel supports up to five full-duplex talkers plus unlimited listen-only users, and packs can talk directly to one another, so a camera team, stage crew, or house-of-worship volunteers can all hear and speak at once. Encrypted frequency-hopping spread-spectrum keeps the link private and stable in crowded RF, with latency held under 35 ms so conversation stays natural.

The pack is ultra-compact, light, and water-resistant for real-world use, and its internal battery runs up to 10 hours on a shift. It recharges over USB, so a single hub can top off several packs between calls. It ships with a holster, a neck strap, and a USB charging cable.
