1. Key Advantages of the Rd-03_V2

Winner of the “Distance Battle”: It supports up to 10 meters of detection range. My room is about 8 meters deep, so with the Rd-03E’s 7-meter coverage, it always felt like it was “just one step away” from perfection. The Rd-03_V2, on the other hand, covers the entire room with no sweat.

Supercharged Features: Beyond basic detection, it allows up to 15 threshold settings, which work like 15 invisible defense lines mapped across the room. Each threshold covers 0.75m, enabling detection up to 10.5m.

Smart “Mind Reader”: It can tailor an “invisible sensing grid” for your home layout — like having personalized spatial sensing coverage based on your environment.

2. Testing Experience — Solid 10/10!

A Blessing for Lazy Users: The PC debugging tool deserves a shout-out! It can auto-generate recommended threshold settings based on your room layout — like having a professional “private detective” fine-tune the configuration for you, saving tons of manual debugging time.

Almost “Creepy” Precision: Although I didn’t measure exact values, you can clearly feel that its distance detection accuracy is sharper than the Rd-03E. That level of effortless confidence only comes from a well-designed product.

3. Tips for Using the Rd-03_V2

Before you “master the skill,” here are a few small but important details that are not explicitly mentioned in the documentation — read these to avoid traps:

Detection distance varies by user state: The 10m range applies when you’re moving. If you’re lying still on your bed scrolling on your phone (“stealth mode”), the effective range drops to 6m. For micro-movement detection, it’s around 8m. So don’t expect it to detect you at 10 meters if you’re motionless like a ninja.

Don’t “double-connect”: You cannot use the PC tool and the OT2 output at the same time. Once connected to the PC tool, the OT2 level output becomes locked. Think of it as: you can’t have both a fish and a bear’s paw at once. (Shared by Ze Ge – not yet personally tested)

There’s more to the reporting mode: Apart from “0” and “1” mentioned in the manual, there is also a value “2,” and likely “3.” Based on testing:

  • 2 = Micro-motion
  • 3 = Stillness (This is still an assumption and not yet verified)
