Questions asked first.

Does it work over CGNAT and consumer cellular?

Yes. The Nebli Drones field proxy makes only outbound connections to the Nebli cloud relay; nothing inbound is required. CGNAT, double-NAT, hotel WiFi, hotspot, Starlink: if the proxy can make outbound traffic to the public internet, the relay carries the rest. No firewall rules to coordinate with the carrier. No port forwards.

What drones does it work with?

DJI drones connect directly, no install required: see the DJI drones page for the three ways in. Anything else that exposes RTSP video and MAVLink on its local network runs through the Nebli Drones relay instead, covering most other professional drones used in public-safety operations, including Parrot, Skydio, Autel, and custom builds based on PX4 or ArduPilot. Nebli Drones does not modify drone firmware. If you have a candidate drone and you're not sure, send us its product spec and we'll tell you within a day.

What about latency? How "live" is live?

Sub-second is typical on stable terrestrial paths: hotspot in a city, Starlink with line of sight, fixed broadband at a command post. Latency depends on your field network, and we don't guarantee a specific number because we don't control your uplink. The Hover Relay app (and hover logs) shows live link counters so you can see what the path is actually doing.

What about packet loss? What's the operator going to see when the link is bad?

The relay carries a loss-recovery layer in both directions. Single-packet drops on a healthy cellular link are recovered transparently and do not produce visible artifacts. Sustained high loss (5%+) on a saturated uplink will eventually show up as pixelation regardless of any recovery layer. That's a UDP-video reality. The Hover Relay app shows live link health so the operator can read the state at a glance, and the relay's logs preserve the same data for after-action review.

Can multiple people watch the feed at once?

Yes. The operator client at the command post is the primary surface. The optional public viewer gives you a browser URL the incident commander can hand to a partner agency or a public-information officer; they don't install anything. Concurrent viewers on the public-viewer side are not metered today.

Does it record? What's the chain of custody?

For a relay-connected drone, yes: the canonical recording is field-side, to a labeled SD card on the proxy, local-first by design, so an uplink failure doesn't lose footage. The operator swaps the card and hands it to evidence the same way they'd hand off a body-worn-camera card. A DJI drone has no field proxy, so cloud recording is its primary cloud-held copy instead of a fallback. On any plan you can also opt a deployment into cloud recording: the flight is muxed to cloud storage so it's browsable and shareable from the dashboard, auto-deletes on a tier-based schedule (Pilot 7 days, Crew 30 days, Fleet 1 year, Enterprise custom), and is deletable sooner. The relay itself forwards video and never retains it. See Security.

What does compliance look like?

Nebli has not been audited or certified against CJIS, SOC 2, FedRAMP, or HIPAA as of today. The platform is built with the practices those frameworks expect (per-session secrets, HMAC integrity, AWS-hosted compute, no warehousing of customer data) but does not carry a third-party attestation. If your procurement requires one, raise it during discovery. We will give you a straight answer about whether the framework is on a credible path or whether Nebli is the wrong fit for that procurement. See the Security page for what we do today.

How does pricing actually work?

A flat monthly fee per tier. You are not charged per drone. Each tier includes a set number of drones and raises your other caps (members, tenants, teams) and unlocks features. Pilot is free and includes one drone; Crew and Fleet include more; Enterprise is sales-led with an annual floor, for multi-agency and procurement-driven contracts. The pricing page has current rates. There are no per-viewer charges on the public viewer; bandwidth above ordinary-course usage may be billed separately, with notice.

Is there a self-service portal? An API? An SDK?

Yes to the portal: dash.nebli.ai is where you sign up, create and manage deployments, invite members, and handle billing, with no sales call required. There is no public API or SDK today; programmatic integration isn't an offered surface yet. (The Nebli CLI drives the field proxy and operator client, but it's a runtime tool, not a management API.)

What happens to my data if we end the contract?

Field-side SD recordings are on your hardware and stay with you. The relay holds no customer video; if you enabled cloud recording, those copies are deleted. Session and usage events are retained only about a week; the flight-index metadata follows your tier's retention; account records are removed on termination. Specifics live in the master services agreement.

Can my agency host its own relay?

Self-hosting is not the product Nebli sells today. Nebli is operated as a managed service, and the cloud relay is part of what you're buying. If a procurement requires on-prem hosting, that's a conversation to have early; it's a different shape of engagement than the standard contract, and we will be honest about whether it's a fit.

Does my DJI drone work with Nebli?

Your controller decides, not your drone. If your DJI Fly app has a Live Streaming option, the drone streams to Nebli; the basic DJI RC is the one controller that has no such option. Enterprise drones on DJI Pilot 2 get both streaming and binding. Check your model and controller.

Does my DJI Mini work with Nebli?

The Mini 5 Pro and Mini 4 Pro stream with any controller they ship with. The Mini 3 Pro and Mini 3 stream with the RC-N1, but not with the basic DJI RC, which has no live streaming in DJI Fly. The full model list is here.

Why is there no Live Streaming option in my DJI Fly app?

You are almost certainly on the basic DJI RC. DJI Fly has no live streaming on that controller, which is a limit of the DJI app rather than anything to do with Nebli. Pair the same aircraft with an RC-N1, RC-N2, RC-N3, RC 2, RC Pro or Smart Controller and the option appears. See which controllers stream.

Will my stream be 1080p?

That depends on the controller too. The RC-N3, RC-N2 and RC-N1 stream at 1080p. The RC 2, RC Pro 2 and RC Pro cap at 720p, which DJI attributes to the controller hardware. Controller-by-controller detail.

Who actually operates this?

Nebli is responsible for the cloud-side infrastructure, monitoring, and continued development of the platform, and is the contracting party on the master services agreement.
