Development of Dynamic DNS Allocation System for L&T Electrical and Automation to allow their DVR (Digital Video Recorder) vendors to create DNSs for devices sold to end-customers.

Client: Larsen & Toubro

Project:  Web App Dev for Dynamic DNS Allocation


The critical business need was to enable L&T’s end-customers to monitor and access Digital Video Recorder remotely from anywhere.


  • Visits and interaction with Sparsh (Client).
  • Balsamiq mockups of solution.
  • Poker Planning, Agile methodology with daily stand-ups, sprints and retrospectives.
  • Test Driven Development
  • Code and Progress of work shared with Client on Git and Trac.
  • Daily 15 min interaction with Client during stand-up, to ensure maximum communication and quick reactions.


  • Devices can be configured with the DDNS Service.
  • DDNS sends “API” calls to update its status on Sparsh servers.
  • Users login to their accounts and monitor their DVRs (Digital Video Recorders).

“Client business has grown many times since the implementation.”


  • Client received huge appreciation from new & existing customers for this feature.
  • Users can stream video recordings remotely from anywhere with zero downtime.
  • Users can anytime retrieve previous recording stored on remote servers.
