Reolink Argus PT Ultra review – A solar powered 4K WiFi Pan-and-Tilt smart security camera

Reolink Argus PT Ultra Solar Panel Instllation

Nearly four years ago, I reviewed the solar-powered Reolink Argus PT pan-and-tilt security camera. The device worked (and still works) mostly fine, but it was at a time when security cameras did not implement AI features like people and vehicle detection just yet relying only on PIR motion sensors so I’d get plenty of false positives. The WiFi connection is not overly reliable either especially when I tried to access the camera from outside my house, something that does not happen with the PoE and 4G LTE models from the company. Reolink asked me whether I wanted to review the new Reolink Argus PT Ultra security camera with higher 4K resolution, dual-band WiFi support, as well as people, vehicle, and pet detection, and most of the same other features found on the older Argus PT. So I took up on the offer and I’ve used it for about one month […]

HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces. HARDWARIO CHESTER specifications: Wireless modules/chips Raytac MDBT50Q-P1MV2 Bluetooth 5.0 module based on Nordic Semi nRF52840 Arm Cortex-M4F MCU with 1MB Flash memory, 256kB RAM Nordic Semi nRF9160-SICA-B1A-R7 LTE-M/NB-IoT system-in-package (SiP) with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM Murata CMWX1ZZABZ-078 LoRa module as […]

Telink energy harvesting wireless module to enable batteryless remote controls

Telink Energy Harvesting Multi protocol Wireless module TV remote control

Telink TLSR8273-M-EH is a multi-protocol wireless connectivity module with energy harvesting capabilities implemented through Nowi’s PMIC, and designed for batteryless devices (or ones with “forever batteries”) such as TV remote controls, but also wearables, and electronic shelf labels among others. The solution is based on a 48MHz RISC microcontroller that supports Bluetooth 5.1 LE, 802.15.4 (Zigbee/RF4CE/6LoWPAN/Thread), and 2.4GHz proprietary protocols. With a single module integrating all main components required for batteryless operation, Telink says its solutions reduce BOM and size, as well as supply chain complexity, and improves user-friendliness by removing the need for battery swaps. Telink TLSR8273-M-EH specifications: Core – 32-bit RISC microcontroller @ up to 48 MHz (CoreMark 1.25/MHz) Memory – 64 KB SRAM with 32 KB retention Storage – 512 KB flash RF Bluetooth 5.1 LE up to 2 Mbps, with AOA/AOD support, Bluetooth Mesh IEEE 802.15.4 radio for Zigbee, RF4CE, 6LoWPAN, Thread 2.4GHz proprietary protocols RX […]

ESP32 board with 150Mbps 4G LTE modem also supports RS485, CAN Bus, and relay expansion

LILYGO has designed another ESP32 board with a 4G LTE modem with the LILYGO T-A7608E-H & T-A7608SA-H variants equipped with respectively SIMCom A7608SA-H for South America, New Zealand, and Australia, and SIMCom A7608E-H for the EMEA, South Korean, and Thai markets, both delivering up to 150 Mbps download and 50 Mbps upload speeds. The board also supports GPS, includes a 18650 battery holder, and features I/O expansion headers that support an add-on board with RS485 and CAN bus interfaces, in a way similar to the company’s earlier TTGO T-CAN485 board with ESP32, but no cellular connectivity. LILYGO T-A7068E-H/T-A7608SA-H board specifications: Wireless Connectivity WiFi & Bluetooth – ESP32-WROVER-E module based on ESP32 dual-core processor @ 240 MHz with 4MB flash, 8MB PSRAM, 2.4 GHz WiFi 4 and Bluetooth 4.2/5.x connectivity, PCB antenna Cellular connectivity Data transfer speeds 4G LTE – Up to 150 Mbps downlink, up to 50Mbps uplink 3G HSPA+ […]

Solar-powered Bluetooth headset with Powerfoyle nano-material band remains charged at all times

Blue Tiger Solare is a solar-powered Bluetooth headset that you may never need to charge thanks to a Powerfoyle solar cell headband comprised of a “nano-material that transforms any outdoor and indoor light into clean, endless energy”. Solare Bluetooth 5.1 headset is said to be military-grade (MIL-STD-810), offers 97% noise cancellation, and is mostly designed for “road warriors” who may require a Bluetooth headset that’s charging continuously. I initially thought it would probably work better for hikers, bicycle and motorbike riders, than car drivers unless we’re talking about convertibles, but Blue Tiger caters to professional truck drivers. Solare highlights: Bluetooth 5.1 with up to ~90 meters range High-quality speaker Microphone with 97% noise cancellation Works with Sir and Google Assistant Endless Battery Life with Powerfoyle solar cell flexible headband Temperature Range – -40°C to +50°C Certifications IPX4 ingress protection rating MIL-STD-810 for extreme environments and ruggedness Solare solar-powered Bluetooth headset […]

Reolink Go Plus 4G smart security camera with solar panel – Unboxing and first setup

I’ve received several Reolink IP cameras either connected over WiFi or Ethernet, but the company has just sent me Reolink Go Plus 4G security camera together with a solar panel that would let me access the camera from anywhere with cellular network connectivity. Reolink Go Plus integrates a 4MP camera and supports person and vehicle detection, just like Reolink RLC-810A model I reviewed earlier this year. I have three Reolink cameras, and I’m somewhat satisfied except that the connection to WiFi cameras is often unreliable, and I have to rely on Cloud backup to play video captures most of the time. The Ethernet-connected Reolink RLC-810A has a much more reliable connection. So I’ll have to see if the Reolink Go Plus camera is more accessible over 4G LTE than WiFi cameras. I’ll start the review by checking out the packages and going through the initial setup for the Reolink Go […]
