## Comparison Table

| Dimension | ViewPro Z40K | USG-231 | Factual Basis |
|-----------|-------------|---------|---------------|
| **Video Resolution** | 4K (3840×2160) @ 25/30fps; 8.29MP effective | Full HD (1920×1080); ~2MP effective | Fact #1, #2, #8 |
| **Sensor** | Panasonic 1/2.3" CMOS, 25.9MP total | Sony CMOS (likely 1/2.8" or 1/1.8" STARVIS), ~2MP | Fact #1, #11, #21 |
| **Optical Zoom** | 20x (FOV 62.95°→3.45°) | 30x (FOV 63.7°→~2.1°) | Fact #3, #8 |
| **Extended Zoom** | 25x iA (4K), 40x iA (FHD) — digital crop | 3x digital (90x total) — digital crop | Fact #3, #8 |
| **Gimbal Type** | 3-axis, ±0.02° accuracy | 2-axis, accuracy not published | Fact #4, #8, #12, #13 |
| **OIS** | 5-axis Optical Image Stabilization | None (digital EIS only) | Fact #4, #9, #14, #15 |
| **Wobble/Jello** | Minimal — yaw compensated + OIS | Susceptible — no yaw compensation, EIS can warp | Fact #12, #13, #14 |
| **Image Crispness at Max Optical Zoom** | 4K at 20x = 8.29MP of detail at 3.45° FOV | FHD at 30x = ~2MP of detail at ~2.1° FOV | Fact #2, #8, #19 |
| **Low-Light** | 0.05 lux @ F1.6, 65dB DR | If Sony STARVIS: 0.00008 lux, excellent | Fact #7, #24 |
| **Weight** | 595g (all-in-one) | 590g camera + 250g VPB = 840g total | Fact #6, #10 |
| **Autopilot Integration** | PWM/TTL/SBUS/UDP (needs custom integration) | Pixhawk/Ardupilot plug-and-play | Fact #22, #23 |
| **Combat/Field Proven** | No public combat deployment data | Proven on Shark UAV in Ukraine combat | Fact #16, #17 |
| **Price** | $2,999–$4,879 | Not public ("cost-effective") | Fact #20 |
