If you are asking whether the Lockin Veno Solar Face works in the dark, the answer is yes: Lockin says its face-recognition system uses infrared fill light, so a porch light is not required for face recognition. The lock’s product page also describes face entry for low-light and day-and-night use.
That answers recognition, not charging. The porch light does not replace daylight for the integrated solar panel, and face recognition can still depend on your distance, face position, enrollment, and a clear scanning window.
Does the Lockin Veno Solar Face work in the dark?
Yes. The official Veno Solar Palm/Face FAQ says the Veno Solar Face is equipped with infrared fill light for recognizing faces in darkness. In practical terms, you do not need to leave a visible porch bulb on solely so the lock can see your face.
This is a capability description, not a guarantee that every attempt will succeed. Treat the porch light as optional assistance for your approach and surroundings—not as a required part of the face-unlock system.
Why infrared recognition is different from solar charging
The Veno Solar Face has two separate light-related functions:
| Function | What it needs | What a porch light means |
|---|---|---|
| Face recognition | The lock’s infrared fill light, plus a usable face view | Not required for recognition in darkness |
| Solar assistance | Daylight reaching the integrated panel; the FAQ specifies at least 1,000 lux and a battery below 90% before harvesting starts | A typical porch bulb should not be treated as a substitute for daylight |
So you can turn the visible porch light off after dark and still use face entry. The solar panel simply will not harvest energy from darkness. For a shaded, covered, or apartment entry, check the product’s daylight conditions before relying on solar assistance as a maintenance plan.
How to get a better nighttime face-recognition result
Use this short setup and arrival check:
- Stand in the documented range. Lockin’s FAQ gives an effective face-recognition distance of 1.64–2.30 feet (50–70 cm). At the stated 50 cm optimum, it gives a height range of 3.94–6.56 feet (1.2–2.0 m).
- Face the scanning area. Keep your face visible and avoid an extreme angle or an obstruction that changes the view of your face.
- Enroll more than one view when needed. Lockin recommends re-enrolling under different lighting conditions, including day and night, or from different angles. The FAQ says the system supports up to five sets of data per user.
- Keep the scanning window clean. Fingerprints, oil, dust, condensation, or other obstruction can reduce recognition precision. Wipe the exterior scanning area according to the care guidance in the current manual.
- Test before depending on it. With the porch light off, try the lock from the normal approach and standing distance. If it does not recognize you consistently, use the Lockin Smart App to review enrollment and settings, then keep a backup method ready.
What if face entry does not work at night?
Do not solve every failed attempt by adding more visible light. First check the basics: your distance, face position, enrollment quality, obstructions, and whether the scanning window is clean. Intense light aimed directly at the sensor can also affect recognition, so more light is not automatically better.
The Veno Solar Face provides other unlocking methods, including a PIN code, app control, a mechanical key, and voice-assistant control. The product page lists five methods in total. Keep a mechanical key in a secure, accessible place, and know where the exterior Type-C emergency-power connection is before you need it. The FAQ says a depleted battery can be temporarily powered through that exterior port or opened with the backup mechanical key.
Remote app and voice features may depend on the lock’s connectivity and the relevant platform. A backup PIN or mechanical key is therefore useful even when the porch light is off or Wi-Fi is unavailable.
Should you leave the porch light on anyway?
Leave it on if you want safer footing, a clearer view of the doorway, or better visibility for visitors and cameras. Do not leave it on because the Veno Solar Face requires visible light for face recognition—the official product and FAQ information support nighttime recognition with the lock’s infrared fill light.
If you are buying the lock for a covered porch or another low-daylight location, separate the decisions: confirm that the door and exterior assembly fit the installation requirements, then decide whether the available daytime light is sufficient for solar assistance. The product page notes that the interior assembly is for indoor use and that covered or shaded locations may not be suitable for solar charging without enough daylight.
Bottom line
The Lockin Veno Solar Face works in the dark and does not require a porch light for face recognition. Its infrared fill light supports recognition in darkness. Solar charging is a separate daytime question, and reliable entry still benefits from correct distance, enrollment, a clean sensor, and a backup method.
