Security reset of builder-fitted smart locks and cameras when buyers move in
TL;DR Gablereset shows up on handover day and makes sure the buyer, and only the buyer, controls the app lock, cameras, video door phone and automation hub the builder fitted. Installer accounts go, passwords change and firmware gets updated. Builders pay per flat, and owners can renew a yearly patch round.
Premium Indian projects now ship with connected doors and cameras. One large developer's premium flats in Mumbai came with an app-controlled main lock and a camera pair streaming the living room and the lobby[1], and lock makers say digital locks are fast becoming a standard builder fitting[2]. Every one of those devices was set up months earlier by an installer, often on shared accounts.
Published research shows where that goes wrong. A 2025 study of one commercial smart lock found former guests could still open it after their access had expired[3]. India's own consumer IoT code asks for no universal default passwords and easy deletion of data when ownership changes[4]. So who checks that at handover? Nobody, as far as I can tell.
A two-person crew turns up with the builder's handover team. They list every connected device in the flat, move admin rights on the lock, cameras and hub to the buyer's phone, delete installer, show-flat and test accounts, change the hub and Wi-Fi credentials, update firmware and switch off any cloud features the buyer doesn't want. The buyer signs a one-page record of what was changed and the builder gets a tower-wide report.
After that, owners or the residents' association can buy a yearly round - firmware updates, an access audit (who can open the door today) and a reset whenever a tenant or domestic worker leaves.
The seed promised AI that predicts and fixes home threats. We reframed it because we found no independent evidence that prediction works for home devices, while stale access and unpatched firmware are documented and easy to check. Gablereset sells a verified state, not a forecast.
The builder pays at handover, out of the fit-out quality budget, much like snagging. There is no public price for this in India, so treat ours as a guess - roughly ₹1,500–4,000 per flat. Owners and landlords pay for renewals, which we'd put at ₹1,500–3,000 a year. For context, a single premium home firewall sells for US$949 (about ₹91,800)[5], so some premium households already spend real money on network control.
Builders have been adding app locks and cameras since about 2021[1], and the first wave of those flats is now passing to tenants and resale buyers. In September 2025 integrators at CEDIA Expo were told to sell maintenance plans that include firmware updates and to treat door locks as entry points[6]. India's camera security requirements, notified in March 2024, show the government is watching the same devices[7].
We found no published count of new Indian homes delivered with connected locks or cameras. If you want a number then build it bottom-up - count the premium towers in one city with smart fit-outs and multiply by flats. One adjacent signal is the Mirai botnet, which grew in 2016 by trying factory logins on cameras and routers[8], and that's why default credentials became the first rule in consumer IoT codes[4].
Home-automation vendors install and support systems in Indian towers, including biometric locks and video door phones at a Kolkata luxury tower[9]. Their after-sales desks fix faults but don't certify that installer access is gone. In the US, CEDIA-member integrators sell security service plans to homeowners[6]. Home-firewall makers sell the hardware route[5]. We found no Indian firm selling an independent security reset to builders at handover, and that's your gap.
| Difficulty | Moderate (41/100) |
| Starting capital | ₹45–85 L |
| Time to launch | 4–6 months |
The technical work is moderate. Each brand of lock and camera has its own admin-transfer quirks, so your real asset is a playbook per model that grows with every visit. The harder part is getting builders to sign on and running crews for handover days that slip without warning, which they will.
No government permit applies to this service. You need the baseline plus signed permission for every flat.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't trust AI to say a lock or camera is secure. Only the crew's hands-on check proves that.

Here's what can go south -
I think this is a good fit for a founder with field-service and home-automation experience in one metro with plenty of premium launches. If you want pure software margins then this isn't it. Prove two things first - that two builders will pay per flat in a live tower, and that a crew can finish a flat in under 90 minutes.
Plan for roughly ₹45–85 L, mostly on trained crews, tools and the time it takes to sign builders.
No permit applies. You need company registration, GST, a signed mandate from the builder and buyer, and DPDP consent before touching any device.
Yes, wherever builders fit smart locks and cameras in new homes. Check local data protection law and any consumer IoT security rules.

Thinking about building Gablereset or something close to it? The deciding bit is getting a builder's handover team to put a security step on their checklist, and I am happy to help you work out that pitch. If you need a hand, you know where to find me. Talk to Yash →
