Frequently asked questions

No. The visitor just points their phone camera at the QR code and the call starts directly in the browser. Only residents use the Nelum app.

R$7.99 per unit (apartment or house) per month, with no base fee and no pricing tiers. There's a one-time activation fee equal to 10 months, which is R$79.90 per unit. Example: a 20-apartment building pays R$159.80 per month and R$1,598.00 once.

No. Nelum is not a hardware integrator. We are a 100% cloud-based intercom focused exclusively on audio and video communication between the entrance/visitor and the resident. Triggering locks or gates remains independent.

Never. Nelum operates 100% in compliance with LGPD (Brazil's data protection law). Calls are routed through our cloud, protecting all of the resident's personal information.

The QR code plate at the entrance needs no power or internet on site, because it's just a plate. The call uses the visitor's and the resident's mobile data or Wi-Fi. So even if the building loses power, the intercom keeps working as long as the phones have signal.

No. Nelum uses no cables, central unit or handsets in the apartments. Installation means mounting the QR code plate at the entrance and registering the units in the panel.

Yes. Since it doesn't depend on existing wiring, it works in any building. The plate can be mounted next to the current intercom, and both can run side by side during the transition.

The building manager decides what happens when nobody answers: the call can be forwarded to the front desk, the visitor can leave a message, or the screen can show that the unit is unavailable. It's configured per unit in the panel.

Activation happens within 24 hours of registration. Residents download the app and can receive calls as soon as the plate is at the entrance.

When a repair means replacing cables, the central unit or several handsets, the cost often approaches a new system and the problem tends to come back. Nelum has no wiring or central unit to maintain, so the cost is predictable: a fixed monthly amount per unit.

Hotels pay R$7.99 per month per call point that receives calls, such as the front desk, restaurant and services, not per room. A typical hotel has about three points. There's a one-time activation fee equal to 10 months, and extra QR code plates are charged separately.

Yes, the guest uses their own smartphone connected to the hotel's Wi-Fi or their 4G/5G network to scan the QR code in the room and start the call.

Through a simple web panel on the front desk's computer, or via tablet/smartphone, receiving an instant notification showing which room the call is coming from.

No. Our system is strictly a 100% cloud-based intercom for communication. Triggering turnstiles, gates, and relays remains the responsibility of the access control (hardware) system your company already uses.

Yes, calls generated by the QR code can be routed directly to your call center or operations base, streamlining your operators' workflow.
