Lidar vs ultrasonic, radar and camera — where laser ranging actually loses
Board-level modules · published single-unit prices · figures verified 2026-10-23
Ultrasonic wins on clear liquid and dust, radar wins in rain and fog, camera wins on classification. Laser time-of-flight wins on angular precision and on a small spot at long standoff. The failure mode of laser is not distance, it is an unclean window or a target that is not where the beam is.

What this page does not claim
It does not quote competitors' specifications from memory, and it publishes no number our catalogue does not carry. Where a figure matters and is unpublished, ask for the datasheet.
Frequently asked questions
The same answers are published below as visible text and as FAQPage structured data, so the page and the markup cannot drift apart.
- Do you publish prices?
- Yes — the published single-unit price for every class is on the price ladder page, dated 2026-10-23. Volume tiers sit below these numbers and are quoted per order.
- Against what target is the maximum range measured?
- Long-range figures are stated against a 2.3 × 2.3 m reference target at the stated reflectance and visibility; short-range classes are stated against a 90% whiteboard. Compare the test condition, not the headline metre count.
- What interface do the modules use?
- UART-TTL with a documented frame and checksum on every published class. There is no native analog or 4–20 mA output; RS-485 needs a host-side transceiver.
