Introduction: Automatic light tracking becomes relevant when a stage must illuminate several moving people across defined performance zones.
Theater and school stages often involve more than one movement path. A lead performer may cross the stage while supporting performers remain in separate areas. A school event may move from a lectern to a presentation zone and then to a performance area. The main question is whether the number of tracked people, frequency of zone changes, and available fixtures justify evaluating an automatic tracking system. TraceLock uses a host, signal base stations, and individual Beacon/Tag devices to link target movement with assigned lighting effects. Its stated capacities include up to four simultaneous targets, up to 32 tracking effects, and control of up to 60 fixtures.
Automatic tracking is most useful when lighting tasks change repeatedly within a planned production structure. In a theater scene, for example, two principal performers may move independently, with each carrying a separate Beacon/Tag so the system can distinguish between them. On a school stage, one tag might follow a presenter moving between a lectern and demonstration area while another is assigned to a participant waiting in a performance zone. These situations create recurring followspot or fixture-switching tasks that can be programmed as tracking effects. By contrast, a speaker who remains at a fixed mark may be adequately served by a static fixture and conventional cues. The limit of up to four simultaneous targets provides a practical starting point. Productions centered on one to four individually identified speakers or performers are suitable candidates for evaluation. For a larger ensemble, designers could consider tracking selected principals while lighting the remaining performers by zone. Up to 32 tracking effects can support changes between scenes, songs, presentations, or other stage activities. Each effect can be planned around the required fixtures, positions, and lighting behavior. The goal is to match those effects to the running order rather than use the full capacity without a production need. TraceLock can also switch between regular lighting programs and tracking effects. A designer might use conventional cues for an opening sequence, activate tracking for a moving speaker, and return to programmed looks for a group performance. This allows automatic tracking to support selected parts of the production alongside manual followspot work, programmed cues, and operator decisions.
A multi-target design connects three elements: the person carrying a Beacon/Tag, the fixtures assigned to follow or respond to that person, and the stage zones through which the person moves. TraceLock is stated to control up to 60 fixtures. It can use DMX moving heads for tracking and activate static fixtures according to target position, allowing moving light and zone-based illumination to work within the same design. The practical fixture quantity depends on fixture functions, channel requirements, stage geometry, and the effects required for the production.
Each tracked person carries an individual Beacon/Tag. The available target positions should therefore be assigned to meaningful lighting roles rather than simply to anyone who appears on stage. In a play, two tags could be assigned to principal actors, one to a narrator, and one to a performer entering from a separate area. For a school production, the tags might be assigned to a host, a teacher, and two student presenters. Each target can then be linked to an appropriate effect or fixture group. When two targets share a scene, their assigned fixtures need suitable positions and enough separation to avoid confusing or competing beams. Rehearsals should cover entrances, crossings, tag handovers, and the points at which each target enters or leaves the tracked area. This preparation connects the technical target limit to actual production responsibilities. It also identifies scenes in which individual tracking should give way to a shared stage look.
Zone division allows different fixtures to respond as a target moves across the stage. A performer leaving a central acting area for a side platform may move beyond the useful coverage of one fixture group and into another. TraceLock can switch tracking between fixtures assigned to those zones, while static fixtures can also respond to the target’s position. This approach is relevant to wide stages, thrust areas, side presentation spaces, and school halls that use several activity areas during one event. Zone boundaries should reflect actual fixture coverage and expected movement paths. A boundary placed across a common stopping point could cause unnecessary switching. Positioning boundaries within natural transition areas can make the lighting change more purposeful and less distracting. Target count, fixture allocation, and zone design should be planned together. Four tracked people do not necessarily need four dedicated fixture groups throughout the venue. Some scenes may use individual tracking, while others may use a shared zone look. Each fixture should also be assessed for whether its mounting position, beam movement, and optical range suit the assigned target area. A useful initial plan marks target routes, performance zones, fixture positions, and the points where tracking should take priority over regular cues.
Base-station placement is part of the system design because target-related signals must reach infrastructure positioned around the tracking area. Indoor wireless location systems can be affected by walls, scenery, metal structures, equipment, audience areas, and people through signal obstruction and reflection. A clear rectangular stage may therefore require a different arrangement from a long hall, an irregular thrust stage, or a set containing large scenic walls. Available hanging positions, network routes, and the physical layout of the working area all influence the configuration. TraceLock has three separate coverage descriptions. A four-base-station version is described as covering 200 square meters. Another specification gives coverage of up to 600 square meters, with expansion through additional base stations. A larger example uses up to eight base stations for approximately 900 square meters, or about 30 × 30 meters. Each figure relates to a different configuration description and requires confirmation for the proposed venue. Published guidance also recommends 15 meters between base stations and gives a maximum communication distance of 25 meters in a stage environment. Stage shape, mounting positions, obstructions, and the required tracking area should all be considered alongside floor area when choosing the quantity and placement of base stations. A site assessment should follow the actual production path. Mark where each target enters, pauses, crosses another target, approaches scenery, and leaves the stage. Compare those routes with potential base-station positions and the usable coverage of the existing fixtures. Rehearsal testing should use representative scenery, costumes, audience conditions, and normal performer movement rather than relying only on an empty-stage walk-through. Site-specific testing is worth checking coverage, accuracy, response, zone-boundary behavior, and operation under expected movement and temporary obstruction conditions. Existing fixtures also affect project suitability. TraceLock is intended for use with DMX moving heads and a DMX console, but fixture models, control functions, protocols, and channel mapping require project-level review. For an assessment with a DMX lighting controller manufacturer or DMX lighting controller supplier, provide the venue drawing, stage dimensions, fixture schedule, console information, target count, proposed zones, and representative show cues. These details support a review against the stated target, effect, fixture, and base-station capacities.
Automatic light tracking is worth evaluating when a stage repeatedly follows one to four identified people, switches fixtures between defined zones, or alternates between regular cues and tracking effects. TraceLock supports up to four simultaneous targets, up to 32 tracking effects, zone division, and control of up to 60 fixtures. Project suitability depends on movement paths, fixture positions, stage shape, scenery, base-station placement, and wireless conditions. Submit your stage plan, fixture models, console details, target routes, and zone requirements to request a configuration discussion, demonstration plan, and quotation.
A：TraceLock supports up to four simultaneous targets. Each tracked speaker or performer carries an individual Beacon/Tag, and the project configuration depends on the number of tags and the lighting role assigned to each target.
A：Yes. TraceLock supports stage-zone division and can switch tracking between assigned fixtures as a Beacon/Tag moves from one zone to another. Static fixtures can also respond according to target position, with zone boundaries and fixture assignments planned around the stage layout, fixture coverage, and movement routes.
A：The approximately 900-square-meter description is a larger configuration example using up to eight base stations. TraceLock separately describes four base stations covering 200 square meters and another configuration reaching up to 600 square meters, so the appropriate arrangement depends on stage shape, obstructions, mounting positions, and target routes.
