Case study
Metro Command Centre
Infrastructure · Bengaluru — 40+ station video federation, dual NOC desks and redundant WAN.
01 · Challenge
What the client needed to solve
The operator ran legacy analog CCTV at older stations while newer lines used incompatible IP systems. Incident operators switched between four client applications, slowing response during peak hours.
Network links between stations and the central office lacked redundancy — a single fibre cut had previously blinded an entire corridor for six hours.
02 · Approach
How Hello Trading structured the program
Hello Trading led a discovery phase mapping every station's camera inventory, retention needs and operator workflows. We designed a federated VMS architecture with edge recorders, standardised analytics rules and a dual-path MPLS plus LTE backup WAN.
Migration ran corridor-by-corridor during night maintenance windows, with parallel recording to avoid evidence gaps.
03 · Solution
What was delivered
- Central command floor with 2×4 video wall and dual operator desks
- Federated VMS linking 40 stations with global search
- 1,200 cameras — mix of new 4MP domes and retained encoders
- Redundant core switching and dual WAN with automatic failover
- Integration with PA/help-point alarms for video pop-up
- Operator SOPs and 120 hours of scenario-based training
04 · Result
Measured outcomes
Mean time to locate incident video dropped from 4.2 minutes to under 45 seconds. The corridor fibre cut drill proved seamless failover — operators retained live views within 90 seconds.
Monthly NOC reports now track camera health proactively; offline devices are restored before shift handover 94% of the time.
