Are Automatic Gates Safe and Secure?

An automatic gate can control a vehicle or pedestrian entrance, but it does not automatically make a property safe or secure. Safety is about preventing people and vehicles from being struck, crushed, trapped or exposed to other hazards. Security is about reducing unauthorised access and supporting detection and response. A good design addresses both without allowing one objective to undermine the other.

What an Automatic Gate Can — and Cannot — Secure

A gate can channel traffic through a controlled point, keep the entrance closed between authorised movements and make casual unauthorised entry less convenient. It cannot guarantee that crime will fall, stop a determined attack, identify a borrowed credential or prevent one vehicle following another. The outcome depends on the whole perimeter, gate construction, locks, controls, visibility, operating procedure and response when something unusual occurs.

That layered approach is consistent with NSW Police Crime Prevention Through Environmental Design guidance, which treats access control as one of several strategies alongside surveillance, territorial reinforcement and space management. Start with a site-specific threat and crime-risk assessment rather than an unsupported promise that a gate will prevent crime.

Security Questions to Resolve

Define who needs access, at what times, in which direction and under which exceptions. Decide how residents, employees, contractors, visitors, deliveries and emergency services are handled. The access control system should support prompt credential cancellation, appropriate event records and a controlled fallback when communications fail. Remote controls, PINs, mobile credentials, intercom release and licence-plate recognition each create different sharing, privacy and support risks.

Mechanical layout matters too: check climbing and reaching opportunities, vulnerable hinges or guides, lock engagement, gaps beside or below the gate, exposed release mechanisms and how the gate interfaces with the fence. Where monitoring is justified, camera security should cover the approach, credential interaction and incident area with lawful retention and access controls. Detection is useful only if someone receives, verifies and responds to the event.

Safety Requires a Movement-Risk Assessment

Automated gates can create striking, crushing, shearing, drawing-in and trapping zones at leaves, posts, hinges, guides and the travel path. SafeWork NSW’s industrial gate guidance records serious incidents and calls for risk assessment, competent installation, inspection and maintenance. The required controls depend on the gate and its users; photoelectric beams, safety edges, presence detection, guarding, force limitation and warning devices are not universal substitutes for one another.

Electric drives within scope should meet the applicable product-safety requirements. AS/NZS 60335.2.103:2024 covers specified electric drives for gates, doors and windows; the 2016 edition remains current during the transition period to 29 November 2027 and regulators may apply editions differently. Product compliance does not replace a site risk assessment, correct installation or commissioning.

Design the Failure State

Document what happens during loss of mains power, flat backup batteries, controller failure, fire alarm, damaged detection or a network outage. The safe and secure state may differ by site and direction of travel. Users need a controlled manual-release procedure, emergency access arrangements and a way to prevent an isolated fault from becoming an indefinite open gate or a blocked exit.

Maintenance Protects Both Outcomes

A misaligned leaf, worn guide, damaged safety device, unreliable lock or shared credential can erode safety or security long before the gate stops moving. Use documented gate service and maintenance to inspect mechanical condition, controls and safety functions, record defects and confirm repairs. After an impact, forced-entry attempt or safety-device fault, isolate the gate as necessary and have it assessed before normal use resumes.

The Practical Answer

An automatic gate can be an effective part of a safer, more controlled perimeter when it is selected from a real risk assessment, integrated with appropriate credentials and monitoring, commissioned for the site and maintained. It is not proof against intrusion and it is not inherently safe. Ask the designer to show how each identified hazard and threat is treated — and what operational responsibility remains with the property manager.
