The long range surveillance UAV
The DeltaQuad Pro #VIEW is designed for organizations who need an eye in the sky.
Its smart features and powerful performance enable effective surveillance & reconnaissance strategies.
Key Features
Flight time of up to 110 minutes
This is including a payload. Being able to stay in the air for a long time is crucial for effective surveillance missions.
Autonomous object following & tracking
Running proprietary control software allows the system to safely and intelligently follow a human, car, vessel, or even another UAV.
VPN Secured command center integration
Control & command sharing enables you to let operators anywhere in the world take over control of the UAV through WiFi.
50KM HD video range (or unlimited via LTE/4G)
We are the only platform that can offer up to 50KM transmission range of HD quality video from a hand-held remote controller.
Deployable in rain or snow
Smart technology gives the DeltaQuad the unique ability to safely fly in moderate rain & snow.
Airborne within 2 minutes
No pre-flight calibrations are necessary. This feature allows the DeltaQuad to be airborne in under 2 minutes.
Thermal/IR night vision
Heat sensors help spot living organisms during nighttime and enable 24/7 surveillance missions.
Fully autonomous missions
Fully autonomous missions from takeoff to landing are possible, even beyond communication range.

Your investment secured & your pilots trained
The DeltaQuad platforms come with the full force of the DeltaQuad team behind you.
With elaborate training, personal support, and a skilled support staff your team will have the resources to achieve your objectives, with the confidence and skills to operate the platforms.
Full warranty for up to 2 years, with fast resolutions and readily available spares for any circumstance, will ensure maximum availability and the peace of mind that your investment is made with minimal risk.
Discover autonomous object following
Autonomous object following is the ability of the DeltaQuad Pro #VIEW to autonomously follow an object and to track it with the camera. Using the touch-screen enabled controller, the pilot can tap on any moving object, and the UAV will automatically alter its flight path to follow.
- Touch screen & point click following
- Follow a car, a human or even another UAV
- Object following through remote device or command center
Advanced safety features ensure a secure flight
Automated pre-flight checks
The DeltaQuad automatically performs pre-flight checks. Depending on the workflow settings it will prevent take-off if certain conditions fail.
Mission Validator
Using the Mission Validator you can be assured the mission is safe to fly based on the checks performed.
Redundant flight system
A redundant flight system allows for automatic fallback recovery in the event of a failure in the fixed-wing or hover flight system.
Continuous in-flight monitoring
The UAV monitors itself during flight. If it is incapable of maintaining safe fixed-wing flight it will abort the mission and revert back to rotor flight.
ADS-B
The ADS-B add-on can detect and avoid most manned aviation. This is often required for certified operation and improves overall safetyADS-B
