| Meeting Room AV Solution | Boardrooms, training rooms, discussion rooms and presentation spaces that do not require a full remote-conference workflow. | Speakers and amplification where required, microphones, projector or display, projection screen where specified, source connection, signal switching, cabling, equipment mounting, basic control, testing and user handover. | Room size, ambient light, viewing distance, acoustics, source devices and operating simplicity determine the design. A projector and speakers alone do not create a conference system. |
| Conference & Collaboration Solution | Hybrid meetings, management rooms, client presentations, training and teams that regularly use Teams, Zoom or compatible SIP-based conferencing. | Meeting-room AV scope plus conference camera, microphone system, DSP where required, wireless presentation, conferencing endpoint or room computer, display, speakers, USB/IP signal path, room control, network coordination, platform testing and handover. | Teams, Zoom and SIP are not interchangeable licences or room modes. HJ confirms the selected platform, user accounts, device compatibility, echo control and support boundary before quotation. |
| Auditorium & Multi-Purpose Hall AV Solution | School halls, auditoriums, houses of worship, function rooms, training centres and multi-purpose venues. | Audience and stage audio design, microphones, mixer/DSP where required, amplification and loudspeakers, LED/display/projector and screen where specified, source and signal distribution, control position, rack/cabling, system tuning, commissioning and operator training. | Audience capacity, acoustic behaviour, stage use, rigging, electrical supply, sightlines, emergency systems and operator skill must be surveyed. Final structural and authority requirements remain project-specific. |
| HJ PA & Audio Distribution | Schools, retail, offices, factories, commercial buildings and public areas. | Basic, zoned or IP-audio architecture, source and microphone inputs, amplifiers, speakers, schedulers or network endpoints where specified, cabling, tuning, tests and training. | Emergency voice alarm or life-safety scope is not implied by a general PA package and must satisfy the relevant design and authority requirements. |
