Whether you're monitoring your home, managing a retail chain, or overseeing a multi-site operation, having reliable remote access to your security cameras is essential. Kalay is the official mobile app from ThroughTek (also known as TUTK), built on the powerful Kalay AI-IoT cloud platform — giving you live video monitoring, two-way audio, cloud and SD card playback, push alerts, and multi-device sharing from one unified interface.
What Is Kalay?
Kalay is a free video surveillance app designed to work with any IP camera, DVR, NVR, or AI-enabled smart box built on ThroughTek's Kalay platform. The name "Kalay" comes from an indigenous Dawu word meaning "handshake," symbolizing the seamless connection between your devices and your phone.
Unlike single-brand camera apps, Kalay supports devices from hundreds of OEM manufacturers worldwide — making it one of the most versatile surveillance apps available. With over 90 million connected devices across 190+ regions, the Kalay platform is a proven infrastructure for both consumer and enterprise surveillance.
The app has a 1.9 rating on the App Store and 2.2 on Google Play, with over 100,000 downloads. It supports 8 languages including English, French, German, Italian, Japanese, Chinese, and Spanish.

Cloud Recording & Storage

You can review, download, and manage cloud recordings through the app's playback feature. For users who prefer free storage, local SD card recording is supported at no additional cost.
