NapCat Smart Video doorbell review – A battery-powered dual-band WiFi video doorbell with AI features

NapCat WiFi video doorbell review

NapCat R112 is a 5MP video doorbell with dual-band 2.4/5GHz WiFi, AI features such as human and package detection, 2-way audio, and no subscription. It’s waterproof – rated IP65 – so it can be used outdoors, and powered by either a built-in battery or traditional wires. The company sent me a sample of the Napcat R112 for review. I’ll check out the camera in battery-powered mode only in this review, install it on the wall close to the gate of my house, and use the Napcast Android app to access the camera and answer calls.

Ochin V2 tiny Raspberry Pi CM4 robotics carrier board gets micro HDMI port, Fast Ethernet support

Ochin V2 CM4 robotics carrier board and USB-C board

Ochin V2 is an update to the tiny Ochin Raspberry Pi CM4 carrier board for robotics applications and drones that adds a micro HDMI port, support for Fast Ethernet through pads or a GHS connector (no RJ45 connector), two user LEDs, and a few other changes. The form factor remains the same at just 55 x 40 x 4.7mm, or about the size of a Raspberry Pi Compute Module 4, which in combination with a range of USB, UART, I2C, and SPI interfaces, makes it an ideal candidate for space-constrained applications such as robotics system or UAVs. Ochin V2 specifications (differences against Ochin v1 shown in bold or strikethrough): Supported modules – Raspberry Pi CM4 with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (the CM4 Lite is not supported since there’s no microSD card on the board), 4Kp60 H.265 decode, 1080p30 H.264 encode, […]

Waveshare Thermal Imaging Camera Module – Raspberry Pi HAT or USB-C model, 80×62 resolution, dual FOV options (45°/90°)

Waveshare Thermal-90 USB and Thermal-90 Camera HAT

The Waveshare Thermal Imaging Camera module comes in two variants, namely the Thermal-45/90 Camera Raspberry Pi HAT and Thermal-45/90 USB Camera. The main difference between the two is that the HAT is designed to be attached to a Raspberry Pi, Pi Zero, or any other SBC that features a Pi-compatible pin layout like the Sipeed Longan Pi3H, Banana Pi BPI-M4, Radxa Zero 3W SBC, and others. On the other hand, the USB module can be connected to any PC, Android, or other device with a USB connection. The camera features a shutterless design, which is why it can produce a thermal imaging video stream output of up to 25 frames per second (FPS). Additionally, Waveshare offers options for different fields of view (FOV) – a basic version with a 45° FOV and a wide-angle version with a 90° FOV, making it suitable for applications like IR thermometers, industrial temperature control, […]

Waveshare UGV Rover – A 6-wheel AI robot built around Raspberry Pi 4/5 and ESP32

Waveshare Unmanned Ground Vehicle Rover(UGV) for Raspberry Pi 4 and Pi 5

The Waveshare UGV Rover is a 6-wheel robot platform based on Raspberry Pi 4 or 5 as well as an ESP32 module and built for remote exploration, object recognition, and autonomous navigation. Since the source code for the platform will be open-sourced it can also be used for educational purposes, programming, robotics, AI experimentation, and many other applications. This Unmanned Ground Vehicle (UGV) rover features a 2mm thick aluminum body, six 80mm shock-absorbing tires, and a four-wheel drive system controlled by an ESP32 sub-controller. The sub-controller also handles sensors, LiDAR, cameras, and more. The brain or the main controller of the rover is a Raspberry Pi SBC – either a Pi 4B or Pi 5 – which notably handles computer vision and machine learning operations. Since the mounting holes are designed to fit a Raspberry Pi, it is safe to assume that it will fit other SBCs with the same […]

Alfa Networks AHST7394S Wi-Fi HaLow module enables low-power, long-range IoT connectivity up to 1km

Alfa Networks AHST7394S HaLow

Taiwanese wireless equipment manufacturer, Alfa Networks, and US-based Wi-Fi HaLow semiconductor company, Newracom, have collaborated to develop the AHST7394S Wi-Fi HaLow module. The solder-down module is based on Newracom’s NRC7394 SoC, a low-cost and high-efficiency HaLow SoC chipset providing up to 17dbm output power and capable of connecting to a maximum of 8K devices within a single network. The NRC7394 also supports a standalone mode, which enables the execution of a wide range of IoT applications on the embedded ARM Cortex-M3 CPU. While HaLow is more energy-efficient than other Wi-Fi types, low-power operation modes such as legacy, TWT, and WMM-PS can reduce power consumption further. The AHST7394S Wi-Fi HaLow module supports a data rate of up to 15Mbps, over 600 times faster than LoRaWAN while maintaining a good range (over 1km). The second-generation HaLow module is perfect for building long-range, ultra-low-power networks in sub-1 GHz, license-exempt frequency bands. It is a […]
