Video Cat-Eye Smart Door Lock

The HKM-8791379 is an aluminium-alloy smart door lock with a built-in video cat eye, a real-time view screen on the indoor panel and six ways to open the door: face recognition, fingerprint, PIN code, RFID card, the mobile app and a mechanical key. The outdoor panel runs a dual-lens camera above a backlit keypad with a status strip and a hidden keyhole, the indoor panel carries a colour screen with playback controls and a manual handle, and both panels ship in Black or Grey with the same full-automatic lock body inside.

Picture the door on a weekday evening: the camera wakes as someone approaches, the indoor screen shows who is standing outside before anyone touches the handle, and a family member walks in with a glance at the face sensor while the lights and curtains of a linked smart home scene follow the unlock. On delivery day the same screen answers the bell without opening the door, and the app logs every unlock event for later review. That is the range the HKM-8791379 is built around.

At a Glance

• Video cat eye with dual-lens camera and real-time view screen on the indoor panel
• Six unlock modes: face, fingerprint, PIN code, RFID card, app and mechanical key
• Aluminium alloy panels with a full-automatic lock body and Grade A cylinder
• Two finishes in the range: Black and Grey, identical configuration across both
• Wi-Fi app control for remote unlock, unlock logs and scene settings
• Works with a companion app and mainstream smart-home scene automation

Materials and Construction

Both panels are machined from aluminium alloy with a slim vertical profile: the outdoor unit stacks a dual-lens camera module on top, a fingerprint sensor and a backlit numeric keypad in the middle, and a hidden mechanical key cylinder behind a cover at the bottom, finished with a slim status light strip. The indoor unit pairs a colour view screen with three playback buttons, a manual handle for free egress and a thumb-turn knob, so the door can always be opened from inside without power.

The lock body is a full-automatic mechanism driven by a motorised deadbolt, rated Grade A on the cylinder security scale and built to fit wooden, steel, stainless steel, brass and aluminium doors. The app layer runs on Wi-Fi through the companion app, and the same hardware is offered in two finishes — Black and Grey — with identical electronics, identical unlock modes and identical mounting hardware in the box.

How It Works

Each unlock method runs its own path into the same lock controller. The face module reads a 3D face map at the top of the outdoor panel, the fingerprint sensor verifies a stored print in about a second, the keypad accepts PIN codes with scramble-entry support, and the RFID reader handles registered cards. The app sends a remote unlock command over Wi-Fi and records the event, while the mechanical key is the offline fallback when electronics are unavailable.

The video cat eye works independently of the unlock path: the dual-lens camera wakes on approach or on doorbell press, streams to the indoor colour screen in real time, and can hand the feed to the app for remote viewing. Scene automation is supported through mainstream smart-home ecosystems — an unlock event can trigger lights, curtains and other linked devices as part of a family routine.

Placement and Use

The lock mounts on the entry door as a full replacement for a standard handle set: the outdoor panel sits on the exterior face, the indoor panel on the interior face, and the motorised lock body bridges the two through the door cutout. It is built for residential and apartment entry doors in the supported material list, and the camera height is set to frame a standing visitor's face without tilting the lens.

Everyday use is hands-full friendly: groceries in both hands means a glance at the face sensor opens the door, a child uses a PIN, a cleaner uses a time-limited card, and a guest uses a temporary app code. The indoor screen answers deliveries without opening the door, and the manual handle and thumb-turn keep the door operable from inside at all times. This is a security and access product, not a certified fire door or a life-safety device.

Included and Optional

Colours and Finishes

Two finishes are listed for this model: Black and Grey. Each finish covers both panels and the handle set, and supplier photography shows the Black version as a deep matte black with a green status strip while the Grey version carries a brushed silver-grey face with the same strip. The configuration, the camera module, the screen and the lock body are identical across both.

Colour is the only difference between the two versions. Both share the same six unlock modes, the same aluminium alloy panels, the same indoor view screen and the same mounting template, so the choice comes down to matching the door and the surrounding hardware rather than to features.

Care and Maintenance

Wipe the panels with a soft, dry cloth and keep the camera lens and fingerprint sensor free of smudges; a microfibre cloth is enough for the screen indoors. Avoid solvent cleaners on the painted surfaces, and keep the outdoor keypad clear of ice build-up in winter by brushing rather than scraping. Replace the batteries on a set schedule and keep a mechanical key outside the house as a backup.

Check the app's unlock log periodically and remove cards or prints that are no longer in use, for example after a tenant moves out. If the face module is used outdoors in direct sun, re-register the family's faces in the lighting where they normally stand. The lock is an access device, not a certified fire door, and it is not marketed as a fire or life-safety product.
