Seven Systems SL-7739BF

The Seven Systems brand's electronic lock is a relatively budget-friendly solution in a smart handle form factor. Along with the model comes a mortise part, which only controls the latch: for enhanced security, it is necessary to use smart cores with bolts (these mortise elements must be purchased separately). The device is equipped with Bluetooth, allowing synchronization with the Oji Smart mobile app: from a smartphone, it is possible to remotely unlock the Seven Systems SL-7739BF, change access settings, view visit logs, etc.

When using a special gateway (purchased separately), the model can be connected to the internet, and thanks to the integration module, it can work with video intercoms and Ajax alarms. By default, various unlock methods are available — by code, contactless Mifare cards, or fingerprint scanning. The device functions autonomously — powered by four AAA batteries. These should last up to a year or up to 10,000 unlock cycles.

When the power sources are fully discharged, two backup opening options are available — using the included mechanical keys or emergency power via the USB Type C port. Also, consider before purchasing that the smart handle is compatible with door panels 35 to 65 mm thick. This lock stands out for its budget-friendly smart handle form factor and its capability for remote unlocking and access setting changes via Bluetooth synchronization with the Oji Smart app. Versatile unlocking methods, standby power options, and compatibility with additional smart systems enhance functionality and security.
