SONOFF CAM-PT2 indoor security camera review with eWeLink, ONVIF-capable NVR, Home Assistant

Today, we’ll do a quick review of the new SONOFF CAM-PT2 indoor camera, which is the third model after the Slim Gen2 (CAM S2) fixed-angle camera and the Slim camera, both of which we reviewed previously. The CAM-PT2 (CAM Pan-Tilt 2) supports Pan/Tilt/Zoom functions. Its main features are quite similar to the CAM S2, including 1080p resolution, Motion Detection/AI Human Detection, and Privacy Zone support. In addition to Pan/Tilt, it adds new features such as the ability to set Preset Points to remember specific camera positions. It’s also the first SONOFF camera to support ONVIF, on top of RTSP, which has been available since the CAM S2. Let’s take a closer look at the details. SONOFF CAM-PT2 unboxing Inside the white box, you’ll find the camera itself, a mini manual, a USB-C cable, wall plugs with screws, a drilling sticker, and a camera holder. If you want other types of […]

Prophesee Starter Kit GenX320 camera for Raspberry Pi 5 enables low-latency event detection

The Starter Kit GenX320 is a power-efficient, event-based camera designed for the Raspberry Pi 5 that detects events with a latency of less than 150 μs, or the equivalent of about 10,000 FPS. The Prophesee GenX320 sensor offers a 320×320 resolution and a >140 dB dynamic range. The kit connects to the Raspberry Pi 5 like the official camera modules, through the MIPI CSI-2 connector. Starter Kit GenX320 specifications: Sensor – Prophesee GenX320 1/5 inch format event-based vision sensor Resolution – 320×320 array of 6.3μm contrast detection pixels Event Rate – ~10,000 FPS equivalent Latency – <150 μs at 1,000 lux, <1,000 μs at 5 lux Dynamic Range – >140 dB Host interface – MIPI CSI-2 (D-PHY) connector Power Consumption -<50 mW Camera (two variants) M12 mount Focal length – 1.8 Focal ratio (f-stop) – f/2.8 fixed iris FOV – 76° diagonal, 58° horizontal, 58° vertical IR cut filter – […]

Blackout Comms Cluster – A pre-configured off-grid LoRa texting and GPS system with cryptographic security

Blackout Comms Off Grid Encrypted Mesh Texting and GPS

Designed by Altware Dev Shop in the US, the Blackout Comms is an off-grid, LoRa-based encrypted mesh communication system built around ESP32 for texting and GPS location sharing without the need for any cellular networks or internet. The device uses asymmetric encryption and digital signatures for secure communication during blackouts, emergencies, or in remote areas where connectivity is unavailable. The device seemed a little bit pricey at first, but the complete kit includes two customized T-Deck communicators and one Altware Link/Node, all pre-configured and ready to use. Each communicator features a DFRobot GPS, Adafruit DS3231 real-time clock, 5000 mAh battery (≈48-hour runtime), external antenna, and PETG printed case, while the Link/Node integrates its own GPS, RTC, 3000 mAh+ battery, and antenna for cluster support. The system forms a private cluster with encrypted, frequency-hopping communication, signed delivery confirmations, and distributed mesh caching. Beyond messaging and location, it also supports proximity/motion sensing […]

Matter 1.4.2 adds support for WiFi only provisioning for cheaper devices, improves security, and more

The Connectivity Standards Alliance (CSA) released the Matter 1.4 specification in fall 2024, and we skipped Matter 1.4.1 here, but decided to cover the Matter 1.4.2 release, which enables WiFi only provisioning, removing the need for a Bluetooth LE radio often only used for onboarding Smart Home devices. This will enable device makers to reduce costs and hardware complexity by removing the Bluetooth LE radio and the associated software stack in designs where a BLE radio is only used solely for commissioning. While Matter 1.4.2 is a minor dot release, it includes many other changes we’ll cover below. Matter 1.4.2 highlights: Wi-Fi Only Commissioning – Relies on Wi-Fi Unsynchronized Service Discovery (USD), and removes the need for Bluetooth Low Energy (LE) radios to onboard devices to the Matter ecosystems. Security Enhancements Vendor ID (VID) Verification – Matter Controllers can now cryptographically verify that the Admins installed on a device are […]

Embedded Device Security: Protecting Linux Systems with Modern Tools

Embedded Device Security Protecting data on Linux systems

CNXSoft: This is a guest port by Erik Wierich, Senior Engineer at RISCstar Solutions, demonstrating a practical security implementation for embedded devices using standard Linux tools like dm-verity and TPM 2.0. It covers threat models, filesystem security, and TPM-based encryption with working code examples. Nowadays, it is (rightfully) impossible to put an embedded device into the market without comprehensive embedded device security measures. Most new devices store private data that we do not want to see leaked in dark corners of the Internet. We also want to avoid our device ending up as part of a botnet. Linux has a large set of tools to help us with security. What has historically been lacking is a simple, off-the-shelf way to integrate these tools into a secure-by-default configuration. This post will demonstrate how modern tools simplify deployments while ensuring strong security. Embedded Device Security Scope When talking about embedded system security, […]
