ALSOK-G7 from Sohgo Security Services looks almost friendly as it hums across a quiet shopping-mall corridor at night, LEDs glowing faintly in blue. The white body reflects ceiling lights, and the soft motor whir is the only sound. This is not a toy but a working guard.

How the ALSOK-G7 patrols

The ALSOK-G7 is a self-driving security robot designed to patrol large indoor spaces such as shopping centers, stations and office lobbies in Japan. It navigates via maps created for each facility, using lidar and cameras to avoid people and obstacles. An ALSOK product release describes it as a mobile platform that can operate for several hours per charge.

On patrol, the robot checks for suspicious objects, detects people in restricted zones and can spot smoke or abnormal heat depending on the sensor package installed. When something looks wrong, it sends images and alerts back to the ALSOK monitoring center so human guards can respond quickly.

Sensors, calls and deterrence

At eye height for a seated person, a camera dome on the ALSOK-G7 quietly tracks the corridor, supported by additional sensors around the body. According to ALSOK materials, the robot can handle two-way voice calls so an operator can speak directly to a person on-site through built-in speakers and microphones. The official service page highlights this as a way to guide lost visitors or warn intruders.

Akira Ai, who serves as president and CEO of Sohgo Security Services, often emphasizes the labor shortage in Japan’s security industry in interviews. The ALSOK-G7 is positioned as a tool that allows one guard to cover a far larger area, while the robot’s visible presence and recorded video add deterrent value for petty theft and vandalism.

Daily use in Japanese facilities

In practice, facility managers program patrol routes so that ALSOK-G7 rolls past entrances, escalators and blind corners at fixed times. Some deployments include automatic elevator integration, so the robot can ride between floors without human help, according to ALSOK case descriptions.

For a mall tenant arriving early, meeting the robot can feel slightly surreal: the glossy shell passes at walking pace, a soft fan noise audible as its sensors scan their face and badge. If needed, the tenant can tap a panel on the body to call ALSOK’s remote operator for assistance.

Battery, charging and limitations

ALSOK specifies a multi-hour operating time per charge under typical patrol conditions, though exact figures depend on route length and sensor load. The robot returns automatically to a docking station to charge when the battery reaches a preset threshold, ensuring it does not suddenly stop in a busy corridor.

There are limits. The ALSOK-G7 is built for flat indoor floors, not stairs or outdoor terrain. It also relies on good connectivity to stream video and sensor data, so network outages can reduce its benefits. Human guards still handle complex judgment calls and physical interventions.

Market position and stock context

ALSOK markets the robot primarily to Japanese commercial property owners, railway operators and large office complexes, often bundling it with remote monitoring services rather than selling it as stand-alone hardware. That service-heavy model aligns with ALSOK’s broader strategy of recurring revenue from guarding and building management.

Sohgo Security Services shares (ISIN JP3160000000) trade on the Tokyo Stock Exchange, where investors watch whether robotics and integrated services such as ALSOK-G7 can support long-term margins in a tight labor market.
