The Hollyland Solidcom H1-10S is a full-duplex professional wireless intercom system designed to ensure permanent communication between the members of a production team. The standard configuration offered for rent includes 10 Solidcom BPK01 belt housings and a Solidcom ANT01 antenna. Each user can listen and speak simultaneously, allowing for much more natural communication than a traditional push-to-talk system. The system operates in DECT 1.9 GHz, on the 1 880–1 900 MHz range in Europe, and offers a range of up to 500 metres in direct visibility with a correctly positioned ANT01 antenna. Up to 12 communication groups can be configured to separate the different teams: production, cameras, sound, light, production, control, stage or technique. Each BPK01 case has four customizable multifunctional buttons. Each button can trigger up to four actions, building complex workflows with multiple groups, calls or communication channels. The enclosures offer more than 15 hours of range and can be used with wired headsets provided or with compatible Bluetooth headsets and headsets. For larger productions, several ANT01 antennas can be networked. Up to three units can operate as an IP cascade without a central station to manage up to 30 Beltpacks. The addition of a Geo Central Station allows to extend the architecture to up to 80 users, 100 groups and eight antennas ANT01 with transparent roaming
