What we do

Four services, one way of working.

Each one has its own page with the detail. This is the short version.

  • Patch cables plugged into a network switch under a numbered patch panel, its port lights glowing green

    Software and systems

    Websites, apps and internal tools, plus the email, servers and networks a business runs on.

  • A sofa washed in warm light from a wall lamp at dusk, beside a shelf and a window

    Home and space automation

    Lights, climate, curtains and cameras that work together. We supply the devices, install them and look after them.

  • Concept design render of a bathroom vanity: an oval basin on a dark stone top, a wall mixer, a mirror cabinet and rolled towels

    Space design and 3D visualisation

    Homes, offices and rooms designed in 3D, so you can see the light, the materials and the layout before anyone builds.

  • An edit desk in a dark room, a monitor showing a timeline and a desk lamp pooling warm light

    Post-production

    Editing, colour and delivery for films, in collaboration with Obelisk Studio.

The founder

Siddharth Agrawal

Founder, TDH Systems · Udaipur

I trained as an engineer first, with a B.Tech in Computers and Communication Engineering from Manipal University Jaipur. When COVID shut everything down, I was home in Udaipur, and I took a cinematography internship at an advertising agency. That settled it.

After my degree I went to the New York Film Academy in Los Angeles for an MFA in Cinematography, and learned from Anthony B. Richmond ASC BSC and Jacek Laskus ASC PSC.

I contributed to more than 100 productions, and worked as a producer, cinematographer and editor on short films. Exsanguination, which I shot, produced and edited, won Best Production at the International Film & Entertainment Festival Australia.

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.

Whether it is software, a home that runs itself, a room you can walk through before it is built or a film on its way to the screen, I want you to see it clearly first and own it fully after.

How we work

Plan first, then build.

Every project runs the same way, whether it is a website, a smart home, a room or a film.

  1. We start by listening: a call, a site visit or a few emails about what you need.
  2. You get a written plan and a quote before any work begins.
  3. We build to that plan and show you the work as it takes shape.
  4. At handover we walk you through everything, and we stay on for support.
