Reolink OMVI triple-lens AI security cameras combine 4K PTZ camera with dual-lens system with fixed 180° panoramic view

Reolink OMVI Series triple lens AI cameras

Reolink has launched the new OMVI Series of triple-lens AI security cameras, featuring a 4K PTZ motorized camera and a fixed dual-lens system that offers a 24/7 180° panoramic view. The camera also supports AI detection and video search, designed to eliminate the typical blind spots of a standard Pan-Tilt-Zoom (PTZ) camera. The series includes three models: the OMVI 3i PoE, OMVI 3i WiFi, and OMVI X16 PoE. All of them use the same basic design, combining a fixed dual-lens camera for a 180° panoramic view with a separate PTZ camera in a single housing. This setup allows the camera to monitor a wide area continuously while the PTZ lens focuses on and tracks specific objects. Reolink OMVI triple-lens security cameras specifications: The OMNI cameras are supported by the Reolink mobile app for iOS 15.1+ and Android 8.0+, the Reolink Client for Windows 8.1+ and macOS 10.15+, Reolink NVR, and […]

Privacy-focused, open-source Raspberry Pi Zero 2W DIY security camera offers end-to-end encryption, on-device AI

Secluso Open source Raspberry Pi security camera requirements

Secluso is a private, open-source, DIY home security camera system built around the Raspberry Pi Zero 2 W, featuring true end-to-end encryption (E2EE) and on-device AI for human, pet, and vehicle detection. It was designed as an alternative to commercial smart home cameras that require sending raw video feeds to a proprietary cloud, a practice that often raises significant privacy concerns. Developed by Secluso, Inc., co-founded by UC Irvine professor Ardalan Amiri Sani and John Kaczman, the project utilizes Messaging Layer Security (MLS, RFC 9420) to ensure end-to-end encryption between the camera and the user’s smartphone. Because the system uses an untrusted relay (either self-hosted on a VPS or via Secluso’s free beta relay), the server routing the footage only sees encrypted files and cannot decrypt the video or thumbnails. Secluso hardware requirements: SBC – Raspberry Pi Zero 2W Camera – Raspberry Pi Camera Module V1 (OV5647) or V2 (IMX219) […]
