PRISM+, a leading name in consumer electronics, has launched its latest innovation in smart home security—the PRISM+ Sentinel Door Lock and Sentry Gate Lock. These state-of-the-art locks are set to redefine home security in Singapore, blending top-tier protection with modern aesthetics.
The PRISM+ Sentinel and Sentry smart locks come equipped with a range of cutting-edge features, but the standout innovation is their DuoSync functionality. This allows users to unlock both the door and gate locks simultaneously – a first in the market. The Pro models also offer 3D facial recognition, adding another layer of convenience and security.
Jonathan Tan, Managing Director at PRISM+, highlighted the brand’s commitment to pushing boundaries: “With the launch of the Sentinel and Sentry smart locks, we’re setting a new standard in smart home security. These products not only provide top-tier security features but also elevate the aesthetic of any home, all while offering unmatched durability and battery life.”
Durability Meets Design


Built from a single block of aerospace-grade aluminium, the Sentinel and Sentry locks are designed to be both robust and visually appealing. The unibody design, created through precision CNC machining, ensures sturdiness, while the anodic oxidation coating offers protection against corrosion. Additionally, these locks are fire-rated to Singapore Civil Defence Force (SCDF) standards, making them a reliable choice for HDB households.
Despite their durability, the locks do not compromise on design. The Sentinel series, at just 11.5 mm, is the slimmest smart door lock available in the market. Homeowners can choose from three sophisticated colour options—Space Gray, Copper Rose, and Nickel Silver – to match their home’s aesthetic.
The launch of these smart locks further expands the PRISM+ smart home ecosystem. Through the PRISM+ Connect App, users can manage their entire suite of PRISM+ products remotely, including unlocking doors and viewing recordings of visitors. This integration offers a seamless smart home experience, tailored to the user’s preferences.
Pricing and Availability
The PRISM+ Sentinel and Sentry locks are priced competitively, with the Sentinel and Sentinel Pro available at $699 and $799, respectively, and the Sentry and Sentry Pro at $379 and $449. For a more comprehensive smart home setup, PRISM+ is offering bundles that include both door and gate locks, starting from $899. These bundles also come with additional smart home accessories, such as a free Video Doorbell.
The PRISM+ Sentinel and Sentry smart locks are now available for pre-order across all official PRISM+ channels.
