DJI Air 3 Rear Lower Vision Sensor Assembly

Backing away from a subject to reveal the scenery is one of the most common drone shots, and it's exactly when an Air 3 relies on its rear sensors. If they're damaged, the drone can't see what it's reversing toward, and the app will usually say so.

This rear lower vision sensor assembly is listed for the DJI Air 3, part of the drone's all-round vision system. Its listing gives no maker, so we sell it as aftermarket.

Diagnosing Air 3 rear-sensor errors

1. Note whether errors mention rear or backward sensing specifically.

2. Clean the rear lenses and check for cracks.

3. Test in good light over textured ground.

4. Inspect the rear vision flat cable for damage, since it's a cheaper fix.

5. Replace the assembly if errors persist.

After installation

The listing recommends sensor calibration after replacement. Calibrate the vision system, then test backward flight slowly in an open area before relying on rear obstacle sensing.

With the rear sensors working, reveal shots and reverse flight are protected again. Keep the old assembly until the new one has passed a few flights, in case you need to compare connectors.
