If your first priority is walking up to the door with your hands full, choose Lockin Veno Solar Face for its 3D face entry and integrated light-assisted charging. If you want to see, hear, and review activity at the doorstep, choose Lockin Veno Pro: it combines palm-vein and fingerprint entry with a built-in 2K/180° camera, two-way video doorbell, motion detection, and local video storage.

That is the practical answer to Lockin Veno Solar Face vs Veno Pro. Neither is a universal winner. The better fit depends on your entry habit, your need for doorstep awareness, the light around the door, and whether your existing deadbolt meets the model-specific requirements.

Choose Veno Solar Face for hands-free face entry

The strongest reason to choose Veno Solar Face in this comparison is the entry interaction. Lockin describes 3D face recognition, hands-free access in under one second, and recognition designed for users from 3 ft 11 in to 6 ft 7 in. That makes Lockin Veno Solar Face a natural candidate for a front door where people often arrive carrying groceries, a child, or packages.

The face reader is one of five listed access methods: face recognition, PIN code, app control, mechanical key, and voice assistant control. You still have alternatives if the camera cannot recognize a user or if a visitor needs temporary access. The product page also describes one-time, scheduled, and recurring passcodes through the app.

Veno Solar Face is not a video-doorbell substitute in this comparison. Its official product page emphasizes face entry, app controls, alerts, access logs, and solar-assisted power; it does not present the lock as a built-in doorstep camera with visitor video. If you need to check a delivery or speak to someone before opening, that missing video function is the deciding limitation.

What the solar feature does—and does not—mean

The Veno Solar Face product page describes an integrated ABX3™ perovskite solar panel, up to 11 hours of daily light charging, and charging in low light on cloudy or rainy days. Treat that as light-assisted charging, not a promise that your door will never need attention.

The same page gives two useful conditions:

1. Solar charging is described as activating when the battery is below 90%.
2. The panel requires at least 1,000 lux of ambient light to begin harvesting energy.

The page specifically says solar charging is not recommended for an interior garage entry with limited daylight, a covered or heavily shaded patio/rear door, or an apartment/condo entry without daylight exposure. A French door is listed as incompatible with this lock installation.

So, before selecting Veno Solar Face, stand at the planned mounting position and consider the actual light reaching the exterior panel. A covered porch may work when it still receives sufficient daylight; “outdoors” alone is not enough.

Choose Veno Pro for doorstep video and broader awareness

Choose Lockin Veno Pro when the question is not only “How do I get in?” but also “Who is at the door, and what happened while I was away?” Its product page describes:

• LockinCam™ with 2K resolution and a 180° view.
• A two-way video doorbell for visitor interaction.
• 60GHz radar and PIR sensors for person, package, and vehicle detection.
• Customizable detection zones and app alerts.
• 32GB local video storage with no monthly fee stated on the page.

For access, Veno Pro uses palm-vein recognition, fingerprint, PIN code, mechanical key, app control, and supported voice assistants. That makes Lockin Veno Pro the better match for a household that prefers raising a hand or using a finger rather than presenting a face—and for one that wants access hardware and doorstep awareness in the same exterior device.

The trade-off is power and hardware complexity. The official page describes a removable rechargeable battery with up to three months of battery life, low-battery alerts, emergency power-bank or key access, and an optional solar panel sold separately. Video and motion features can affect power use, so the product’s power-management settings and the household’s activity level matter.

Door and placement checks before you buy

Do not decide Lockin Veno Solar Face vs Veno Pro from biometrics alone. Confirm the door first.

Veno Solar Face checks

The current US product page lists these conditions for Veno Solar Face:

• Wooden or compatible standard entry-door setup should be checked against the product instructions.
• Door thickness: 1-3/8 to 2-11/64 inches (35–55 mm).
• Crossbore diameter: 1-1/2 inches (38 mm) or 2-1/8 inches (54 mm).
• Backset: 2-3/8 inches (60 mm) or 2-3/4 inches (70 mm).
• Door hole diameter: 1 inch (25.4 mm).
• Crossbore center to door stop: more than 1-9/16 inches (40 mm).
• The interior assembly is intended for indoor use.

The key extra question for the Solar Face model is daylight at the exterior assembly. A good mechanical fit does not by itself establish a good solar-charging location.

Veno Pro checks

The current Veno Pro page lists:

• Wooden doors.
• Door thickness: 1-3/8 to 2-11/64 inches (35–55 mm).
• Crossbore diameter: 2-1/8 inches (54 mm).
• Backset: 2-3/8 inches (60 mm) or 2-3/4 inches (70 mm).
• Door hole diameter: 1 inch (25.4 mm).
• Deadbolt latch-box depth of at least 1 inch (25.4 mm).
• At least 3 inches (75 mm) between the handle and crossbore center for the solar-panel installation option.

The page says Veno Pro is not compatible with storm doors because they may block the camera, and it is not compatible with round latch-faceplate cutouts. It also says the interior panel should remain in a protected indoor environment.

When in doubt, use the Lockin user manual library and the Lockin FAQ before ordering. If your door has a storm door, mortise lock, French-door layout, unusual trim, or a nonstandard latch cutout, ask Lockin support to confirm the exact configuration.

A simple decision workflow

Use this sequence for Lockin Veno Solar Face vs Veno Pro:

1. Start with the visitor question. If you need a live view, two-way conversation, package/person/vehicle detection, or recorded doorstep events, start with Veno Pro.
2. If video is optional, start with the entry question. If hands-free face entry is the priority, start with Veno Solar Face. If palm-vein or fingerprint entry is preferred, start with Veno Pro.
3. Check the power plan. Veno Solar Face needs useful daylight at the exterior panel and still has a 37 Wh lithium battery plus USB-C emergency power. Veno Pro uses a rechargeable battery and can accept an optional solar panel.
4. Measure the door. Compare thickness, crossbore, backset, hole, latch, trim, and storm-door conditions with the exact model’s documentation.
5. Plan backup entry. Keep the mechanical key or the documented emergency-power method available, and complete enrollment for more than one authorized access method before relying on the lock.
6. Test the real approach. After installation, test face or palm position, nighttime or low-light conditions, door closure, auto-lock behavior, app connection, and the path a visitor takes to the camera or sensor.

Bottom line

For Lockin Veno Solar Face vs Veno Pro, choose Veno Solar Face when the core relief is touchless, hands-free face entry and your door has enough daylight for the integrated solar system. Choose Veno Pro when the core need is doorstep video, two-way visitor communication, local event storage, and palm/fingerprint access—with the optional solar panel and its own door-placement constraints.

Review the exact Veno Solar Face product details, Veno Pro product details, Lockin FAQ, and user manuals before buying. The right answer is the model whose entry method, visibility, power plan, and door fit match your household—not a universal feature count.
