Drone Video for Search and Rescue | Live Feeds for SAR Teams

The Problem

The coordinator is at the trailhead. The drone is over the ridge. The video is trapped on the pilot's tablet.

SAR operations run on distributed decision-making. Ground teams in the field. A coordinator at the staging area who is not the pilot. Partner agencies responding from adjacent counties. A state SAR liaison watching from the regional EOC. Every person in that chain needs situational awareness, and the most powerful tool in modern SAR — a thermal drone circling the search area — produces a video feed that is usually visible to exactly one person: the pilot.

EyesOn is the layer that gets that video to everyone who needs it, in real time, on a phone or laptop, without anyone installing software or creating accounts. Designed for how SAR actually works: multi-team, multi-agency, small budget, high-consequence.

Why It Matters

Capabilities that change SAR outcomes.

Latency

Sub-Second Feed

300–800 ms glass-to-glass. Coordinator sees what the thermal drone sees, instantly. No 15-second RTMP delay that misses the subject moving through a gap.

Night Search

Thermal Streaming

M30T, Mavic 3T, and compatible thermal aircraft stream live thermal in real time. Overlay text for search areas, grid callouts, time stamps — visible to every viewer.

Multi-Team

Coordinator Grid View

One coordinator, multiple drones, one dashboard. Run an east-side and west-side overwatch on the same search simultaneously and watch both in split-screen.

Mutual Aid

Inter-County Guest Links

SAR does not respect county lines. Neither does EyesOn. Text a link to an adjacent team, a state resource, or a helicopter crew standing by — they view in a browser.

Low Bandwidth

Works on LTE Hotspots

Adaptive bitrate, TURN-relay fallback. Runs on the cellular hotspot you hauled up the trailhead road, even on one bar of LTE.

Small Budget

Volunteer-Tier Friendly

Personal ($39/mo) and Professional ($89/mo) self-hosted tiers. Managed ($499/mo) for teams without IT capacity. Nonprofit/volunteer scoping on request.

In the Field

SAR operational patterns EyesOn serves.

Lost Hiker, Night, Thermal Search

A family calls at 21:30. A hiker is overdue on a popular loop trail. The volunteer SAR team launches an M30T from the trailhead with thermal enabled. The coordinator is at the staging area with a laptop. Ground teams are already up the trail, two miles apart, with handheld radios. The coordinator watches the thermal feed live, spots a hot signature thirty yards off-trail, and vectors the nearest ground team by radio. Total time from drone launch to subject located: nine minutes. Without real-time thermal to a non-pilot coordinator, that search takes hours.

Swiftwater / Flood Response

County SAR is called to a vehicle-in-flooded-creek situation. A drone goes up to assess the scene for a rescue team. The ground safety officer watches the feed on a phone while the pilot concentrates on flight. The state resource en route watches the same feed and pre-stages their swift-water raft based on current direction visible in the drone video. Everybody is working off the same visual, live.

Multi-Team Search Pattern

Large-area search with two drones — one on the east drainage, one on the west. Coordinator runs grid view, watching both feeds at once. Ground team leaders each get a guest link scoped to the drone flying over their sector, so they can see their own overwatch on their phone without being confused by the other drone's feed.

K9 Deployment Support

K9 team is working a search grid. Drone overhead provides an aerial view of the dog's progress and any terrain features the handler cannot see from ground level. K9 handler and SAR coordinator share the feed. If the dog alerts, everyone on the call sees the context in real time.

Regional / State Liaison

Large operation where the state SAR liaison is coordinating multi-county resources from a regional EOC 40 miles away. Guest link generated, liaison has the feed, never has to drive to scene for situational awareness. After-action review runs off the same recorded video.

Deployment

Built for teams without IT departments.

Volunteer SAR teams rarely have a full-time IT person. EyesOn was designed for that reality:

Managed tier (Recommended for most volunteer SAR teams). BarnardHQ runs the whole thing on dedicated hardware. You get a URL, coordinator credentials, and guest-link capability. No setup, no maintenance, no upgrades. $499/mo.
Self-hosted Professional tier. $89/mo. One technically-capable member can stand it up on a Synology NAS or a $300 mini-PC at the team's operations trailer. Docker-based, one install script.
Personal tier. $39/mo. For single-drone teams validating the workflow before scaling.

Written line-item quotes for grant applications are standard — DHS SAR grants, state SAR funding, individual sponsor asks, and regional SAR foundation grants all accept EyesOn as a technology line item. We help draft the justification language.

Questions

FAQ

Our SAR team has no IT. Can we actually run this?

Yes. Personal and Professional tiers run on a Synology NAS or a mini-PC that one technically-capable member can set up in an afternoon. If that is still too much, the Managed tier ($499/mo) means BarnardHQ runs the whole thing on dedicated hardware — you just use it. Volunteer SAR teams often pick Managed for exactly this reason.

How does it help during a night search?

A thermal drone streaming live to the SAR coordinator (who is not on the drone controller, probably at a staging area) is the single highest-impact capability in modern SAR. Coordinator sees hot signatures in real time, directs ground teams by radio, and the ground teams never wait for someone to review recorded footage. Sub-second latency is what makes this work — RTMP-level delay defeats the purpose.

Can we share video with a responding state SAR resource or partner county?

Yes. Generate a time-limited guest link scoped to the incident, text it to the state liaison or partner team coordinator, and they view it in a browser. No account, no install, no vendor onboarding. Revoke when the incident closes. This solves the classic multi-agency SAR problem of "we have resources in the field from three counties and nobody can see the same thing."

What drones work with EyesOn for SAR?

Any DJI enterprise aircraft (M30T, M350, Mavic 3 Enterprise/Thermal, Matrice 3TD) and any drone with RTMP output. Thermal-equipped aircraft are the strongest SAR fit — M30T and Mavic 3T feed thermal streams that are exceptionally useful for locating subjects in cover or at night.

Are there volunteer/nonprofit pricing options?

Contact us. We work with volunteer SAR teams directly and can scope multi-year or annual pricing that fits a typical SAR operating budget. Written line-item quotes for grant applications are standard.

What about bandwidth at the staging area? We're often in rural terrain.

EyesOn uses adaptive bitrate and works over LTE hotspots, satellite internet (Starlink Mini is a popular SAR pairing), and any cellular modem that can sustain ~2–5 Mbps upstream. TURN relay fallback handles NAT-traversal on weaker links. For documented field-test numbers, contact us.

Can we record operations for training and after-action?

Yes. Every stream can be recorded locally and archived to the team's storage (NAS, agency evidence system, or encrypted offline drive). After-action debriefs run off the same video the coordinator watched live. Training replays are exactly that — a time-limited guest link to a recorded search.
