Lockin Veno Solar Palm vs Veno Solar Face comes down first to how you want to unlock your door: Veno Solar Palm centers on Venokey™ Palm Vein Unlock, while Veno Solar Face centers on 3D Face Recognition Unlock. Both are Lockin Veno Solar smart locks with ABX3™ Perovskite Solar Self-Charging, but solar-assisted charging should be understood as support for reducing charging hassle—not as battery-free operation.
Quick answer: the main difference is palm unlock vs face unlock
For everyday homeowners and renters, the simplest comparison is the biometric interaction at the door.
Veno Solar Palm may be the more natural choice if you want the door interaction to be deliberate: approach the lock and use your palm. Veno Solar Face may be the more natural choice if you prefer face-based recognition as the main entry experience. The right choice is not about declaring one model universally better; it is about which unlock habit fits your household, front-door layout, and comfort level.
Both models sit within Lockin’s broader Veno Solar line, so the comparison is narrower than choosing between entirely different product categories. You are mainly deciding between palm vein recognition and 3D face recognition while keeping the same solar-assisted smart-lock concept.
What Veno Solar Palm and Veno Solar Face have in common
Veno Solar Palm and Veno Solar Face share several confirmed product facts that matter for home buyers. Both include ABX3™ Perovskite Solar Self-Charging, which uses light to help reduce everyday charging burden. Both include a battery, 5 unlock methods, Built-in Wi-Fi with no hub required, Matter compatibility with Apple Home, Alexa, Google Home, and SmartThings, Auto-Lock, IP53, ANSI Grade 3, an operating temperature range of -22°F to 158°F, and USB-C emergency power.
That means many of the practical buying questions are similar for both models:
- Do you want a smart lock that can work with common smart-home ecosystems through Matter compatibility?
- Do you want a lock with Built-in Wi-Fi instead of planning around a separate hub?
- Do you want Auto-Lock as part of the daily entry routine?
- Is the confirmed IP53 rating appropriate for your door’s exposure, porch coverage, and local conditions?
- Do you have a plan for USB-C emergency power if the battery becomes critically low?
The shared feature set also means buyers should avoid assuming the Face model is a completely different class of lock from the Palm model. Based on the provided product facts, the core decision is not about one having solar assistance and the other lacking it. Both are Veno Solar products. The choice is primarily about the biometric method you want to use every day.
One practical note: specs, availability, ratings, and prices can change. Before buying, confirm the latest product page details directly with Lockin, especially if you are comparing current pricing, package contents, installation requirements, or weather-exposure guidance.
Solar-assisted charging: helpful support, not battery-free operation
The most important power expectation is this: Veno Solar Palm and Veno Solar Face are solar-assisted smart locks, not battery-free devices. The provided product facts confirm that both models include ABX3™ Perovskite Solar Self-Charging and a 37Wh 7.4V 5000mAh battery. In other words, the solar system supports the battery; it does not remove the battery from the product.
Lockin’s Veno Solar positioning is helpful for homeowners because front-door devices are easy to forget until the battery is low. Solar self-charging can reduce the routine charging burden by using available light, and the provided facts state that both models support daily light charging and low-light charging on cloudy or rainy days. That is a meaningful convenience feature for many homes.
However, buyers should not interpret solar-assisted charging as a promise that charging management disappears in every environment. Real homes vary: some doors face direct sun, some sit under covered porches, some are shaded by trees, and some receive limited winter light. A lock on a bright, south-facing entry may have a different light environment than a lock in a shaded hallway or recessed apartment entry.
A practical way to think about it:
- Solar assistance helps replenish stored battery power when light is available.
- The internal battery still matters because the lock must operate when light is limited or unavailable.
- USB-C emergency power still matters as a backup option if the battery becomes critically low.
- Battery monitoring remains part of responsible smart-lock ownership.
This is the safest expectation for a household purchase: treat the solar feature as a charging-support system that can reduce charging hassle, not as a reason to ignore power planning altogether.
What happens at night, in winter, or on cloudy days
At night, there is no active sunlight for the lock to collect. In that situation, Veno Solar Palm and Veno Solar Face should be understood as relying on stored battery power. That is why the confirmed battery is part of the product facts and why USB-C emergency power is relevant.
On cloudy or rainy days, the provided facts indicate that both Veno Solar Palm and Veno Solar Face support low-light charging. This is useful because real front doors do not always receive direct sun. Still, buyers should avoid assuming that low-light charging produces the same result as stronger light exposure in every setting. Cloud cover, shade, door orientation, and the amount of daily use can all affect the practical charging experience.
In winter, the same conservative logic applies. The official product facts list an operating temperature range of -22°F to 158°F for both models, but that does not replace the need to consider available daylight and exposure. Shorter days, shaded entries, storms, and covered porches may reduce available light. If your entry receives very little light for long periods, plan to monitor battery status more closely and understand the emergency-power option before installation.
For homeowners, the key pre-purchase question is: how much light does your door actually receive during a normal week? For renters, the question is broader: does your lease allow lock replacement or modification, and does your entry location provide enough light to benefit from the solar-assisted design?
Use this simple home-light check before choosing either model:
- Look at the door in the morning, midday, and late afternoon.
- Note whether the lock area receives direct light, indirect light, or mostly shade.
- Consider seasonal changes, such as trees with leaves, winter sun angles, and stormy months.
- Check whether a porch roof, screen door, hallway, or recessed entry blocks light.
- Treat solar support as a benefit, but keep a backup power plan.
How to choose the better fit for your household
Choose Veno Solar Palm if the hand-based interaction feels more natural for your household. Its confirmed differentiator is Venokey™ Palm Vein Unlock at 0.17s. This may appeal to buyers who prefer a clear, intentional unlock gesture rather than face-based recognition. It can also be easier to explain to household members: approach the door and use your palm.
Choose Veno Solar Face if face-based entry is the interaction you prefer. Its confirmed differentiator is 3D Face Recognition Unlock under 1s with over 99% accuracy, and the provided product facts include a supported user height range of 3 ft 11 in to 6 ft 7 in. For buyers who like face recognition as a primary unlock method, Veno Solar Face is the model built around that experience.
The better fit depends on household habits more than on a universal ranking. Consider these questions:
- Who uses the door every day: adults, children, visiting family, roommates, or occasional guests?
- Do users prefer presenting a palm or using face recognition?
- Is the lock location comfortable for the intended biometric method?
- Does the entry area provide enough light to make solar assistance worthwhile?
- Are you comfortable with the stated user height range for Veno Solar Face?
- Do you want the decision to be based mainly on unlock interaction, since many confirmed features are shared?
For renters, add a separate permission step before choosing either model. Check your lease, landlord rules, door compatibility, and local requirements before changing a lock. A smart lock can be a personal convenience upgrade, but rental installations should not be treated as automatic or universally allowed.
A balanced recommendation: consider Veno Solar Palm if you want a palm-based biometric smart lock in the Veno Solar line; consider Veno Solar Face if you want a face-recognition smart lock in the same solar-assisted product family.
Backup power and low-battery planning
Both Veno Solar Palm and Veno Solar Face include a 37Wh 7.4V 5000mAh battery and USB-C emergency power in the provided product facts. That matters because solar assistance does not remove the need for a backup plan.
If the battery becomes critically low, USB-C emergency power is the confirmed backup-power option provided for these two models. Buyers should understand where the emergency power port is, what type of USB-C power source is appropriate according to official Lockin instructions, and how to access the port before the lock is installed on a daily-use door.
The provided facts do not confirm specific low-battery alert timing, remaining unlock counts after a warning, app notification behavior, LED behavior, audible alerts, or mechanical-key backup details for these exact models. For that reason, those details should be verified in current Lockin support documentation or with Lockin directly before purchase.
A practical low-battery plan should include:
- Knowing how battery status is shown for your installed setup.
- Keeping a suitable USB-C power source accessible.
- Teaching household members what to do if the battery is critically low.
- Checking battery status more often if your door receives limited light.
- Reviewing official Lockin instructions before relying on emergency power.
This planning is especially important for shaded entries, rental units, vacation homes, and side doors that may receive less regular attention than a main front door.
