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 and Director, TDH Systems · Udaipur

Hi, I'm Siddharth, a cinematographer by training and an engineer by habit. My films have won over 20 international awards and travelled to the European Film Market and the Marché du Film in Cannes. Through all of it I've worked to one motto: Superior Image Quality. At TDH Systems, I bring that same eye for detail to software, homes, spaces and post-production.
