Beijing Digital Huamao Smart Campus

Challenge

Network, security, BMS, parking, access control and energy metering were delivered in phases by different contractors, leaving seven disconnected systems. Property staff spent heavy hours on manual meter reading and patrols while energy bills kept rising, and tenant circuit activation took 2–3 weeks, slowing leasing.

GSS scope of responsibility

GSS owned design, integration, field engineering and resident-plus-remote operations for the campus backbone, wireless, IoT access and operations centre (IOC). Security, building-automation and parking subsystems were supplied by their vendors; energy and video-analytics targets were agreed with the owner.

Solution

GSS built a unified campus backbone and Wi-Fi as the foundation, onboarded 12,000+ IoT endpoints, delivered an Intelligent Operations Centre (IOC), and layered AI video analytics (perimeter / fire-lane / crowd), AI energy optimisation and automated tenant circuit provisioning, with on-site plus remote managed operations.

Background

Digital Huamao is a six-building, roughly 280,000 m² business campus in eastern Beijing hosting more than 180 companies. Built in three phases, its network, CCTV, building automation, parking, access control, energy metering and fire systems were delivered by different contractors, leaving property management juggling seven separate back-ends.

Leasing’s main complaint: after a tenant signed, network and circuit activation took two to three weeks. Property’s main complaint: manual meter reading and patrols were labour-intensive, yet energy bills rose year on year.

Solution

Campus network foundation (traditional network business)

• Unified backbone: the six buildings interconnected on a dual 10G ring with redundant cores; each building runs separate VRFs for property systems, tenant traffic and guest access.
• Campus-wide Wi-Fi: 860 Wi-Fi 6 access points across offices, public areas and underground car parks, with a single portal and enterprise 802.1X.
• IoT access network: wired PoE and LoRa connectivity for 12,000+ sensors, cameras, meters, door controllers and EV chargers, all registered in a single asset inventory.
• Automated tenant circuits: fibre pre-laid to every floor’s telecom room and a carrier meet-me point established on campus by GSS; activation standardised into “contract → ticket → config push → acceptance”, executed by GSS on-site engineers.

Operations centre and AI (AI business)

• IOC platform ingesting all seven systems onto one data bus, with live device status, alarms, energy and footfall rendered on a 3D campus model.
• AI video analytics on campus edge servers for perimeter intrusion, fire-lane obstruction, fall detection and crowd density, pushed to property staff’s mobile app; false-positive rate held under 5% versus manual monitoring.
• AI energy optimisation: a forecasting model trained on two years of consumption, weather and occupancy data drives time- and zone-based HVAC and lighting schedules, issuing weekly recommendations that are pushed automatically to the BMS.
• AI inspection assistant: patrol staff photograph equipment; the model reads nameplates and status and structures the record, replacing paper checklists.

Operations

Two GSS resident engineers plus the remote NOC provide 7×24 coverage across network, IoT and platform layers.

Results

Metric	Before	After
Separate management consoles	7	1 IOC
IoT endpoints	~3,000 (siloed)	12,000+ (unified)
Annual campus energy	Baseline	−18% (first year)
Tenant circuit activation	2–3 weeks	3 working days
Manual patrol hours	~640 / month	~260 / month
