For homeowners and renters comparing Lockin Veno Solar Palm vs Veno Solar Face, the main confirmed difference is the biometric unlock experience: Veno Solar Palm is the palm vein recognition option with Venokey™ Palm Vein Unlock, while Veno Solar Face is the 3D Face Recognition option. Both are part of Lockin’s Veno Solar family and are listed with ABX3™ Perovskite Solar Self-Charging.
Solar-assisted charging is not the same as battery-free operation; both models still use an internal battery and buyers should understand sunlight conditions, low-battery behavior, and backup power before choosing.
Quick Answer for Homeowners and Renters
Choose Veno Solar Palm if your household prefers unlocking by presenting a palm. Choose Veno Solar Face if your household prefers face-oriented unlocking. Based on the supplied Lockin product context and official-site snapshot, both models share the Veno Solar positioning, while the clearest model-level choice is Palm Vein Recognition versus 3D Face Recognition.
A practical way to compare them is:
For everyday residential use, the decision should start with the people who use the door most often: you, family members, roommates, trusted guests, or anyone who regularly comes home carrying groceries, bags, or a child. If the household likes the idea of a palm-based gesture, Veno Solar Palm is the more natural comparison point. If the household prefers face recognition as the primary biometric method, Veno Solar Face is the relevant option.
Renters should also confirm lease rules and landlord approval before changing a lock. Homeowners should confirm door compatibility, installation requirements, exposure to light, and smart home setup details before buying.
What the Veno Solar Palm and Veno Solar Face Have in Common
Veno Solar Palm and Veno Solar Face sit in Lockin’s Veno Solar family, described in the supplied product context as solar self-charging smart locks focused on palm vein and face recognition. The official-site snapshot also lists both models with the same solar technology label: ABX3™ Perovskite Solar Self-Charging.
According to the supplied official-site snapshot, both Veno Solar Palm and Veno Solar Face are listed with:
- ABX3™ Perovskite Solar Self-Charging
- 5 unlock methods
- Built-in Wi-Fi with no hub listed
- Matter compatibility with Apple Home, Alexa, Google Home, and SmartThings
- Auto-Lock
- IP53

Because some purchase details can change, treat snapshot-based details as items to confirm on the current Lockin product page before ordering. That is especially important for live price, package options, exact current product URL, compatibility details, and any updated specification sheet.
For homeowners, the shared feature list matters because it suggests the choice is not only about “which lock has solar.” Both are presented as Veno Solar models. The more important practical question is whether your household wants the palm vein model or the face recognition model.
For renters, the shared feature list does not remove the need to check permission. A smart lock can involve door hardware changes, and lease terms vary. Before installing either model, confirm whether your rental agreement allows lock replacement, whether your landlord requires a physical key option or access plan, and whether the installation can be reversed when you move out.
Palm Vein Recognition vs Face Recognition: The Main Choice
The core comparison in Lockin Veno Solar Palm vs Veno Solar Face is biometric method.
Veno Solar Palm is the model associated with Venokey™ Palm Vein Unlock. In buyer terms, that means the unlock action is built around presenting your palm. This may appeal to households that prefer an intentional gesture at the door rather than a face-oriented interaction.
Veno Solar Face is the model associated with 3D Face Recognition Unlock. In buyer terms, that means the unlock action is built around face recognition. This may appeal to households that like the idea of approaching the door and using a face-based biometric method.
The supplied official-site snapshot includes performance details for each biometric method, including a stated 0.17s unlock speed for Veno Solar Palm’s Venokey™ Palm Vein Unlock and under 1s with over 99% accuracy for Veno Solar Face’s 3D Face Recognition Unlock.
Because recognition performance can depend on real-world conditions and current product specifications, buyers should verify the latest Lockin product documentation before treating those figures as current purchase criteria.
When comparing biometric methods, avoid assuming one is automatically better for every household. Instead, ask:
- Do you want a deliberate palm gesture, or do you prefer face-oriented access?
- Will all regular users be comfortable enrolling and using the chosen biometric method?
- Are there guests, cleaners, dog walkers, or relatives who may need non-biometric access?
- Do you understand what the other unlock methods are on the current model?
- Are you comfortable with the model’s biometric privacy and storage approach, once confirmed in official documentation?
Do not assume unlisted technical details such as liveness detection, encryption method, biometric storage architecture, false acceptance rate, or anti-spoofing certifications unless Lockin’s current documentation confirms them for these exact Veno Solar models.
Solar-Assisted Charging: What It Does and Does Not Mean
The Veno Solar name is important, but it should be understood carefully. Solar-assisted charging is not battery-free operation. Based on the supplied facts, both Veno Solar Palm and Veno Solar Face are listed with an internal 37Wh 7.4V 5000mAh battery. The solar feature is there to help reduce routine charging needs by using available light, not to remove the battery from the system.
The official-site snapshot describes ABX3™ Perovskite Solar Self-Charging as using light to reduce daily charging needs. The snapshot also states up to 11 hours of daily light charging and indicates low-light charging on cloudy or rainy days. Those statements should be read as condition-dependent: actual charging will depend on the entryway, light exposure, shade, season, weather, and how often the lock is used.
For example:
- A front door with regular daytime light exposure may give the solar system more opportunity to help replenish the battery.
- A shaded porch, apartment hallway, covered entry, or north-facing door may receive less useful light.
- Winter daylight hours and cloudy weather may reduce available light compared with brighter seasons.
- Nighttime provides no sunlight, so the lock relies on stored battery power.
- Higher daily usage can affect how much energy the lock consumes between charging opportunities.
This is why buyers should treat solar as a helpful charging support feature, not as a reason to ignore power planning entirely. Before buying, confirm the latest Lockin guidance for your installation environment, especially if your door gets limited sunlight.
What Happens Without Sunlight or When the Battery Is Low?
Without sunlight, the solar element is not receiving sunlight. At night, during extended low-light periods, or in a heavily shaded installation, Veno Solar Palm and Veno Solar Face rely on stored battery power. The supplied official-site snapshot says both models support low-light charging in cloudy or rainy conditions, but it does not support a blanket promise that every installation will stay charged under all light conditions.
When the battery becomes critically low, the supplied official-site snapshot lists USB-C emergency power for both Veno Solar Palm and Veno Solar Face. This should be understood conservatively as an emergency power option for a low-battery situation. Buyers should confirm the exact current procedure with Lockin before purchase, including where the port is located, what power source is recommended, whether emergency power only enables temporary access, and how the main battery is recharged afterward.
Before relying on either model, confirm these low-power details:
- How the lock alerts you when battery is low
- Whether alerts appear on the lock, in an app, or both
- What battery percentage or condition triggers a warning
- Whether Lockin provides an estimate of remaining unlocks after a low-battery alert
- How USB-C emergency power is used in practice
- Whether there is any physical backup access method on the current model
- How long a full recharge takes under supported charging conditions
- What Lockin recommends for shaded, indoor, or low-light installations
The key buyer takeaway is simple: solar-assisted charging can help reduce routine charging needs, but you should still know the backup plan before you install the lock on your main entry door.
