Annke CZ400 AI security camera reviewed with basic and smart events

At the beginning of this month, I started the review of Annke CZ400 AI security camera by listing specifications, unboxing the device, and doing a partial teardown, notably to install a MicroSD card. In theory, the camera comes with more advanced AI features than Reolink RLC-810A 4K CCTV camera that only supports people and vehicle detection, as the Annke security camera can handle face detection, line crossing, unattended baggage detection, and other smart event detections. So let’s see how it performs Annke CZ400 installation The first challenge was the installation, as I told the company I would not be willing to install the camera on the ceiling since I’m renting, and preferred wall-mounting. after checking the user manual that included a wall mount, I decided to go ahead, and get the review unit. But sadly, the wall mount is not included in the package, and Annke even told me they […]

Windows Performance on an Intel NUC 11 Enthusiast Phantom Canyon NUC11PHKi7C

The Enthusiast Phantom Canyon is Intel’s flagship product from its latest NUC 11 range of mini PCs. Specifically targeting gamers it includes an NVIDIA RTX 2060 GPU. In this article, I take a brief look at the performance under Windows and compare it against Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon. Hardware Overview The NUC11PHKi7C physically consists of a 221 x 142 x 42 mm (8.70 x 5.59 x 1.65 inches) rectangular plastic case which is remarkable because of its size and is similar to just a graphics card like NVIDIA’s GeForce RTX 2060 Founders Edition (229 x 113 x 35 mm). It is an actively cooled mini PC and uses Intel’s 10 nm Core i7-1165G7 Tiger Lake processor which is a quad-core 8-thread 2.80 GHz processor boosting to 4.70 GHz with Intel’s Iris Xe Graphics. But it also includes NVIDIA’s N18E-G1-B notebook graphics […]

Zymbit HSM4 & HSM6 security modules work with embedded Linux hardware, Raspberry Pi, Jetson Nano

Zymbit Zymkey security modules, now called Zymkey4i, were first introduced several years ago. Based on the Microchip ATECC508A CryptoAuthentication chip, the modules were available as a USB stick, an I2C module for Raspberry Pi boards, or an SMT component, and designed to enable multifactor device ID & authentication, data encryption & signing, key storage & generation, and physical tamper detection. The company has now informed CNX Software they had launched HSM4 cryptographic protection module and HSM6 hardware wallet with a different form factor for easy integration into embedded applications, and devkits compatible with Jetson Nano and Raspberry Pi SBCs. Zymbit HSM4 cryptographic protection module & devkit HSM4 crypto module key features and specifications: HSM4 is built upon Zymkey4i module, and integrates an Arm Cortex-M0 microcontroller, as well as a secure element likely to be Microchip ATECC508A, or the more recent ATECC608B CryptoAuthentication chip if the company upgrade System Identity & […]

Raspberry Pi case embeds 192 programmable LEDs, speaker, microphone, and sensors (Crowdfunding)

Most Raspberry Pi enclosures are designed to protect your board from dust, provide easy access to ports, and in other cases, ease the installation of hard drives or SSDs. But Abstract Foundry’s LumiCube does much more, and just calling it a case or enclosure is an understatement, as while it does house a Raspberry Pi, it also comes with 192 programmable LEDs placed over 3 panels, a speaker, a microphone, as well as several optional motion & environmental sensors, and a small 2-inch LCD display. LumiCube specifications: Acrylic base 3x RGB LED panels with 64 programmable LEDs each Audio – 2W speaker and microphone Display (optional) – 2-inch 320×240 IPS screen for system parameters or other info (e.g. sensor data) or images.
