What we do

One studio for the technical and the visual.

Every job starts with a written quote and ends with something you own and understand.

What it is
Software that plans and runs a film shoot, from the first script to the last shoot day.
What it does
It turns a script into the schedule, the budget and the daily call sheet.
Who it's for
Producers, production managers and assistant directors who run the set every day.
What it saves
The late nights spent rebuilding schedules, budgets and call sheets by hand.
A modern home at blue hour: lit steps up to a warm-lit entrance, garden lights along the lawn and a softly glowing facade

Lights, climate and security that work as one.

We supply the devices, then design, install and support the system. Where no product does the job, we build one.

Space design

Every room, lit before it is built.

We design rooms in 3D with their real light fittings, so you can see them at noon and at night before work starts.

The founder

Siddharth Agrawal

Founder, TDH Systems · Udaipur

I trained as an engineer, then took an MFA in Cinematography in Los Angeles and worked as a producer, cinematographer and editor on short films. Film taught me to plan every shot before anyone presses record. Engineering taught me to build things that keep working. In 2026 I moved back to India to start TDH Systems, where those two halves meet. I want you to see it clearly first and own it fully after.
