3D Binocular Recognition: Uses dual cameras to calculate depth, preventing the system from being fooled by high-resolution photos or videos.
Integrated Video Intercom: When the doorbell is pressed, the internal 3.5-inch TFT screen activates, allowing you to see visitors without opening the door. It also pushes a "Real-time Video Call" to your smartphone.
Emergency Features: If the 4200mAh-7750mAh Lithium battery runs out, you can jump-start the lock via a USB-C port or use the hidden mechanical override key.
A more standard, robust choice for internal office doors or side entrances.
Semiconductor Sensor: recognizes a fingerprint in under 0.3 seconds. These are much more reliable than older optical sensors, especially for elderly users or those with faint prints.
Virtual Password: You can enter random digits before or after your actual PIN (e.g., xxxx123456xxxx) to prevent "shoulder surfing" from onlookers.
Capacity: Most models store up to 100 fingerprints and 100 passcodes, making them suitable for small-to-medium teams.
Both cameras you've identified are "Off-Grid" solutions, meaning they require no wiring for power or data.
Most battery cameras only record when they "see" motion, often missing the first few seconds of an incident. AOV technology fixes this.
24/7 Low-Frame Recording: The camera captures at a low frame rate (1 fps) constantly, then instantly switches to high-speed HD recording when AI detects a human.
AI Humanoid Filtering: Uses an algorithm to ignore swaying trees or animals, reducing false notifications to your phone by up to 99%.
This is the "All-in-One" solution for large property perimeters or construction sites.
The Triple View: On the mobile app (typically V380 Pro), you get three screens: two fixed wide-angle views for a 180° panorama, and one PTZ view that you can rotate.
4G LTE Connectivity: By inserting a 4G SIM card, the camera functions anywhere with cellular service—no Wi-Fi router needed.
Active Deterrence: It features "Sound and Light Alarm." If an intruder is detected at night, it can trigger Red and Blue flashing lights and a siren.
