A construction site changes daily, many subcontractors work on it, and safety supervision relies on walkarounds. It is an environment where continuous observation adds the most, but which also demands a system that tolerates constant change of scenery.
Typical risks in this sector
Missing helmets and harnesses at height
This is the most common cause of fatal accidents in the sector, and control depends on a coordinator being in the right place at the right time.
Crane and vertical transport zones
Standing under a moving load is prohibited but hard to enforce across a large site.
Unauthorised entry
Sites in built-up areas are exposed to unauthorised entry, including outside working hours.
Lone working in separated sections
A worker performing a task alone, out of sight of others, may wait a very long time for help if they collapse.
What the system detects
- missing helmet or vest in an area where they are required
- a person in the crane working zone or under a load
- entry into a fenced area outside working hours
- a fall or absence of movement for a defined period
- the number of people present in designated zones
Site variability as the main challenge
On a construction site everything changes: the layout of barriers, equipment positions, even the terrain. Zone rules must be quick to move, otherwise within a week they no longer match reality.
What works is a model where the safety coordinator moves zones on the image without involving the supplier. Without that the system ages faster than the building rises.
Many subcontractors, one supervisor
The main contractor is accountable for safety, but people from a dozen companies work on site, with different standards and different workwear. Object detection does not distinguish employers and treats everyone the same.
The event record can become material in conversations with subcontractors. It is worth agreeing up front how it will be used, because that shapes how people regard the system.

Frequently asked questions
Does the system suit a site with no fixed infrastructure?
Yes. Standalone units with their own power and connectivity are used, relocated as the work progresses.
Will it detect a missing harness?
Recognising a harness is harder than a helmet, because it is often covered by clothing. Effectiveness depends on framing and needs checking in the specific conditions.
Can the site be monitored outside working hours?
Yes, and it is one of the simpler applications: at night any presence in an area is an event, so the rule is unambiguous.
