Gatehouse Design: What a Site Security Module Needs to Actually Control Access
Updated 2026-11-01 · JIUJIAN GLOBAL technical team
A gatehouse needs 360-degree visibility with glazing on at least three sides, a barrier positioned so a vehicle stops before the window rather than at it, backup power and communications, and a lockable log for visitors, vehicles and keys.
Gatehouses are the smallest modules on a site and the ones with the highest consequence of bad design: an access point that cannot see, cannot record and cannot communicate is a security gap with a roof.
Siting and visibility
- Position so the operator can see the approach, the barrier and the pedestrian gate without leaving the desk
- Glazing on three sides minimum, with the sill low enough to see a car and a person at the same time
- Set back from the road so a vehicle can stop clear of the highway — a queue at a gate on a public road is a hazard
- Lighting on the approach and on the pedestrian route, on its own circuit
Inside the module
| Item | Why |
|---|---|
| Counter at standing height with a drawer | Passing documents and badges without opening the door |
| Two screens or one screen plus printer | Visitor log and camera feed at the same time |
| UPS and a dedicated circuit | Barrier and comms must survive a power cut |
| Heating and cooling independent of the camp | The post is occupied 24 hours, unlike the camp |
| Toilet or access to one within 50 m | Otherwise the post is abandoned at shift handover |
Access control that survives reality
Manual barriers fail because nobody records anything at 03:00. A boom barrier with a vehicle loop and a badge reader handles staff traffic; manual handling should be reserved for visitors, and the visitor log should be a form that is completed before the barrier lifts. Keep a paper backup of the log — digital systems lose power and networks drop.
Communication
Radio to the site supervisor, a telephone that works when the mobile network does not, and a duress button. All three should be tested at commissioning with the site team present, not just installed.
Hardening without over-specifying
Bollards in front of the glazing, a door that opens outward with a deadlock, and a raised floor where the site floods. Armour plating is rarely justified; visibility, lighting and procedure do more for security than thicker steel.
