Lockin presents the V7 Max smart lock with vein biometric sensor

The brand Lockin expands its catalog with the launch of the V7 Max model. This device combines in a single unit an electronic lock for doors and a video doorbell with camera. The standout feature is its authentication mechanism, which does away with physical keys and uses a scanner that reads the vein pattern in the palm of the hand to grant access. 🔐

How does vein recognition work?

The V7 Max system uses a high-precision optical sensor. This emits infrared light toward the user's hand and captures the image of the internal vascular pattern. A specialized algorithm processes that unique pattern and compares it with the templates stored in the device's memory. If the match is valid, the lock unlocks automatically. Lockin argues that this technology surpasses fingerprint readers in security, as the biometric data is internal and virtually impossible to replicate without the individual's presence.

Alternative access methods:
  • Enter a numeric code on the backlit touch panel.
  • Use an NFC technology card to approach and unlock.
  • Manage opening remotely via the official mobile app.
Biometric data is processed and stored locally on the device to protect user privacy.

Connectivity and video doorbell features

The doorbell module integrates a night vision camera and motion detection capability. The lock runs on batteries and connects to the home network via Wi-Fi. This connectivity allows the owner to receive alerts on their smartphone when someone activates the doorbell, as well as view the live stream from any location. The V7 Max design features a weather-resistant finish to withstand outdoor conditions.

Key system advantages:
  • Advanced biometric authentication via the hand's vascular pattern.
  • Local data processing, without sending sensitive information to the cloud.
  • Complete integration of lock and video intercom in a single hardware.

A balance between innovation and everyday reliability

The Lockin V7 Max positions itself as a smart access solution that prioritizes biometric security. Although vein technology promises a superior level of protection, its effectiveness in daily use will depend on the sensor's precision in recognizing the user in any circumstance. The combination with the video doorbell and multiple opening methods makes it a versatile option for modernizing home entry. 🏠
