Restricted area monitoring: red zones and restricted rooms, on the cameras you already have

A site has two kinds of restricted area, and both can run on the same cameras: safety red zones, dangerous while work goes on (under a suspended load, a press or robot cell, an open excavation), and access-restricted rooms such as electrical and server rooms, chemical and fuel stores and control rooms, where only authorised people may enter. Security alerts have their own pages: intrusion alerts for zones you mark on a camera and fence-line detection for plants and ports.

Some red zones stay put, such as a robot cell. Others move with each lift, or as a laydown area shifts, so a dynamic red zone needs an arrangement agreed before go-live. Interkey sets it up in one of three ways:

1. Pre-drawn zones, switched on per lift. Each lift area named in the lifting plan gets its own zone, active only during its window.
2. A named person redraws the zone. When the work moves, a supervisor or control-room operator updates the zone, and the change is logged.
3. A link to the lifting plan. Where the plan is held in a system, the zone schedule can follow it.

Around moving plant, the risk is often a person close to a vehicle rather than a person in a place. That case is covered in forklift and pedestrian alerts in warehouses and yards.

An access-control system records a badge at the door, not the person who walks in behind it or through a door left open. A camera on the room or its doorway adds that picture:

• a person in the room outside permitted hours raises an alert with video evidence;
• validity windows leave planned maintenance and permitted work quiet;
• door sensors and cameras together show both that a door opened and who came through.

At the entry to a red zone, the same camera can also check that people wear the PPE the zone requires; see hard hat and vest checks at zone entry.

SquintPRO runs on-premise, so footage stays on your site, or in the cloud with 3, 6 or 12 months' retention; for Saudi sites with a policy on where video may be held, on-premise is usually the starting point. It detects that a person entered a zone, not who they are; agree before go-live who sees alerts and footage and how staff are told. Interkey carries out the survey, integration, tuning and support from Riyadh, in Arabic and English.
