Frequently asked questions before a project

Start with minimum viewing distance, content and environment. Closer viewers need a finer pitch, followed by a review of budget, brightness and buildable dimensions.

Outdoor LED requires higher brightness, weather protection and suitable structure. Indoor LED prioritizes close-view detail, uniformity and interior integration.

Most target dimensions can be approached, but final size follows module or cabinet increments. We show the requested and nearest buildable size before approval.

LED is best for one seamless image, large formats and custom shapes. LCD video walls can suit multi-source monitoring where narrow panel bezels are acceptable.

Yes. A CMS can schedule, update and monitor digital signage displays remotely within the project scope.

A site plan, coverage areas, required level of detail, recording duration, lighting conditions and any existing network or VMS platform.

The scope can include Fluke copper tests, OTDR fiber reports, labeling, port schedules and final drawings.

An approved interface such as dry contact can release doors in an emergency, subject to the Cause & Effect matrix and fire consultant approval.

Public address is designed for paging, zones, priorities and intelligible coverage, with background music or emergency messaging where required.

Yes, within an integrated implementation scope, covering installed points, routes, racks, addressing and test records.

A BMS supervises and controls designated mechanical systems and approved electrical interfaces, consolidating equipment status, alarms, operating schedules and trend data.

Typical interfaces include AHUs, FAHUs, FCUs, VAV boxes, chillers, pumps, meters and approved UPS, generator or KNX points, subject to equipment compatibility and scope.

BMS focuses on centralized building supervision, while KNX provides distributed room-level lighting, shading and HVAC control. Approved gateways can connect both layers.

Common protocols include BACnet/IP, BACnet MS/TP, Modbus TCP and Modbus RTU. Selection depends on the connected equipment, network design and approved points list.

DDC controllers process physical inputs and outputs and execute control sequences. An I/O schedule documents each DI, DO, AI and AO point, its function and associated controller.

This depends on platform condition, available integration protocols, controller compatibility and existing backups. A survey and documented points review define the practical scope.

Depending on the contract, deliverables include points lists, I/O schedules, sequences of operation, HMI graphics, as-built drawings, test reports, backups, training and warranty.

KNX is an open building-control standard for distributed lighting, shading, HVAC and sensor functions in homes, offices, hotels and other automation projects.

Essential local KNX functions normally operate over the local control network without internet access. Remote access and selected additional services may require connectivity.

ETS configures individual addresses, group addresses, device parameters, communication objects and scenes. The agreed handover should include the documented ETS project backup.

Yes. KNX-DALI gateways and approved thermostat, FCU or HVAC interfaces can be used after confirming compatibility and the required control functions.

KNX/BACnet or KNX/Modbus gateways can exchange approved monitoring and control points while maintaining local room-level operation.

KNX is a distributed control standard operating locally over a dedicated bus, with devices, addresses and functions documented in ETS. An app may be added as an interface but is not the foundation of local operation.

Arrival, away, meeting, presentation, night and energy-saving scenes can be configured after lighting, shading and HVAC commands are documented in an approved scene matrix.

KNX is used in luxury residences, hotels, offices, meeting rooms and commercial buildings that require reliable, documented and expandable local control.

The agreed package can include topology, device schedules, group addresses, actuator-channel mapping, scene matrices, ETS backups, testing records and user training.

It depends on seating distance, aspect ratio, source resolution and sight lines. Bigger is not always better if it exceeds a comfortable viewing angle.

Projection suits a very large cinematic image in a light-controlled room. Direct-view displays offer higher brightness and simpler use in multipurpose rooms.

Treatment improves sound inside the room; isolation reduces sound transfer to adjacent spaces. Dedicated cinemas often need both considered.

It can be excellent for a medium room and one main seating row when placed correctly. Larger rooms or multiple rows benefit from 7.1.4 or 7.2.4.

The scope can include levels, delay, EQ and subwoofer optimization, plus color, brightness, contrast and HDR setup.
