Smart Home Camera K21: Night Vision Rotating Facial Scanning, Embarking on a New Era of Active Security
In today’s increasingly high demand for home security, K21 smart home cameras redefine security standards with “3D protection+AI intelligent recognition”. This intelligent device, which integrates 2K ultra high definition night vision, 360 ° pan tilt rotation, and precise facial scanning, is not only an “electronic sentinel” guarding the home, but also a thinking and warning home security center, making every corner of the abnormality invisible. ​
1、 Night Eye: 2K ultra clear night vision, making the night as bright as day
Breaking through the limitations of traditional camera night vision blur, K21 is equipped with a starlight level night vision system to achieve clear monitoring of all scenes:
Infrared+White Dual Mode: Equipped with 8 built-in 940nm non red burst infrared lights, capable of presenting high-definition black and white images even in low light environments of 0.01Lux; Automatically switch to white light supplement in case of abnormal situations, instantly illuminating the scene and recording color videos, leaving no escape for intruders at night; ​
Intelligent photosensitive adjustment: The light sensor monitors the brightness of the environment in real time, automatically switches between day and night modes, and avoids strong light overexposure or weak light noise. Whether it is a balcony backlight or a dimly lit hallway scene, the image is always delicate and smooth; ​
2K ultra high definition image quality: 2304 × 1296 resolution paired with a 1/2.7-inch large-sized sensor, the detail capture ability is increased by three times, and key information such as license plate numbers and facial features are clear and distinguishable. ​
2、 Guardian who can turn its head “: 355 ° horizontal+90 ° vertical rotation, cruising without blind spots
The dual axis gimbal motor of K21 endows the camera with the ability of “active observation”, completely bidding farewell to the blind spot of fixed viewing angle:
Autonomous cruise mode: supports customizing 4 cruise routes, with the camera automatically rotating and scanning at preset points, covering key areas such as the living room, hallway, and entrance; ​
Remote real-time control: By dragging the screen with one click through the mobile app, the camera synchronously turns to the target area, and you can click wherever you want to see. You can control the dynamics of pets under the sofa and whether the package has been delivered to the door at any time; ​
Tracking and tracking technology: After AI mobile object recognition is activated, the camera automatically locks onto the moving target (such as a person, pet, or vehicle) and rotates with its movement trajectory to ensure that the target does not leave the field of view. ​
3、 Facial scanning expert: millisecond level recognition to distinguish between family members and strangers
Built in AI facial recognition chip, K21 achieves dual intelligent protection of “identity verification+behavior analysis”:
Accurate facial database management: supports the entry of 20 sets of facial data, and the system automatically learns the facial features of family members. When visitors, couriers, and other strangers visit, the system will immediately push an “Unknown Face Found” alert; ​
Dynamic trajectory tracking: After recognizing the face, the camera automatically follows the target’s movement and records its action route. If a stranger stays at the door for more than 30 seconds, an abnormal alarm will be triggered immediately; ​
Facial expression/posture analysis (optional function): Through deep learning algorithms, abnormal postures such as elderly people falling or children crying can be preliminarily identified, providing more dimensions of security for home care. ​
4、 Universal Security Center: Multi scenario linkage to build an intelligent protection network
K21 is not only a camera, but also the core node of smart home linkage:
Device interconnection: compatible with Wi Fi, Zigbee, Bluetooth protocols, can be linked with smart door locks (automatically closing alarms when opening doors), smart lights (automatically turning on when detecting abnormalities), smoke alarms (synchronously recording videos when alarms occur), forming a three-dimensional security system; ​
Two way voice communication: built-in noise cancelling microphone and speaker, supporting real-time intercom, remotely reminding children to do homework, persuading suspicious persons in front of the door, and communicating at zero distance; ​
Emergency one click call: The camera body is equipped with a physical call button. In case of an emergency, the elderly/child can long press it for 3 seconds to send an alert to the preset contact and start a video call. ​
5、 Dual protection of privacy and storage: local+cloud, secure and worry free
Flexible storage options: Supports local storage with up to 128GB Micro SD card, paired with 7-day loop recording; Optional cloud storage services (encrypted transmission+blockchain authentication), fearless of device damage or theft, and video data will never be lost; ​
Privacy protection mechanism: physical lens occlusion slide, timed sleep function (such as automatic camera shutdown at night), custom privacy area mosaic, triple protection to protect family privacy; ​
Network disconnection and battery life design: Equipped with a built-in 5000mAh battery, it can still last for 4 hours even after a power outage. Paired with a 4G data card (to be purchased separately), it can continue to transmit alarm messages even when the network is disconnected. ​
6、 Ready to use: Minimally deployed, adaptable to all scenarios
Zero installation difficulty: supports two installation methods: magnetic base (no drilling) and wall bracket. Deployment can be completed in 5 minutes, and security systems can be quickly set up for rental and small apartment layouts; ​
Multi terminal real-time viewing: synchronized on mobile app, tablet, and computer, allowing you to view home updates anytime, anywhere during business trips and travels, supporting up to 5 people to preview online at the same time; ​
Strong environmental adaptability: operates in a wide temperature range of -20 ℃~50 ℃, with an IP65 dust and waterproof rating (requires a waterproof casing), and can also operate stably on outdoor balconies and courtyards. ​
