HeimVision HM241 HD NVR Kit Review – Part 1: Unboxing, Teardown and HDD Installation

I’ve reviewed a few solar-powered security cameras in the last year, and from time to time, I’m being asked to review more from time to time, but I asked for a change, and instead, I wanted to look into security network video recorders (NVR). HeimVision offered this opportunity with its HM241 HD NVR Kit which they also call a “wireless security camera system”, and comes with 4 Full HD security cameras besides the NVR itself. In the first part of the review, I’ll check out the hardware, and take the opportunity to install a 3.5″ hard drive, before doing a proper installation, and report my experience about the software in one or two extra articles. HM241 HD NVR Kit Unboxing People working at customs seem to be fond of larger packages, checked it out in details hence the “Opened and Releases” sticker on the package, and I had to pay […]

ESP32-S2-Kaluga-1 “Multimedia” Development Board Comes with Touchscreen Display & Camera

ESP32-S2 secure WiFi processor based on Xtensa LX7 core was first unveiled in May 2019, before the datasheet was released, and the first development boards were showcased in September. The Coronavirus outbreak slowed down progress, but the company has now announced the start of mass production for ESP32-S2 SoC, ESP32-S2-WROVER & ESP32-S2-WROOM modules, and ESP32-S2-Saola-1 development board. So that means we should soon be able to buy any of those. Apart from improved security, ESP32-S2 chip also provides a USB OTG interface and interfaces for HMI (Human Machine Interface) solutions thanks to LCD & camera interfaces. So that’s probably why the company has developed ESP-S2 Kaluga-1 board with an LCD touchscreen display, touch panel, support for camera image acquisition, audio playback, and more. We do not have the full specifications at this stage, but here are some of the highlights of the board: LCD interfaces – SPI interface or 8-/16-/24-bit […]

Reolink Argus PT Review – A Solar powered Pan-Tilt Security Camera

Last year, I reviewed Reolink Argus Eco solar powered security camera, and I’m still using it to date. It’s working fairly well, although sometimes motion detection will not be triggered, or triggered too slowly so it’s not impossible to miss important footage. The PIR function can be tweaked so maybe it’s just a question of finding the right settings for a given location. Nevertheless, the company has now launched a new model called Reolinkg Argus PT that is very similar to the Argus Ego but with PT (Pan, Tilt) function, and I received a sample for review. Since both models are so similar, I recommend reading Argus Eco review first, as I’ll focus on the differences. Reolink Argus PT Unboxing I received two packages like las time: the camera itself, and Reolink solar panel. The camera comes with a WiFi antenna, a wall-mounting set, a USB cable, and some documentation. […]

96Boards compliant Rock960 Development Board Gets a 5.0MP MIPI CSI Camera

VAMRS Rock960 is a 96Boards compliant development board based on Rockchip RK3399 processor that was first unveiled in 2017, but last year it got a low-cost version with Rock960 model C selling for as little as $69. All variants of Rock960 come with MIPI CSI signals exposed via the 60-pin high-speed connector defined in 96boards specifications. So it needs a MIPI adapter board to connect the camera, and a couple of years ago, instructions were posted explaining how to use a MIPI CSI camera on 96boards such as Rock960. It now appears the MIPI adapter board is not for sale on eBay anymore, but that not an issue as e-Con Systems has just launched e-CAM50_CU96 5.0 MP camera designed to work with Rock960 board, and by extension, I assume, other 96boards compliant SBCs that expose a MIPI CSI interface. e-CAM50_CU96 is comprised of three main components: e-CAM55_CUMI0521_MOD camera module with […]

Lindenis V536 SoM & SBC Targets 4K Camera Applications

Back in summer 2018, we wrote about Lindenis V5 single board computer based on Allwinner V5 quad-core Cortex-A7 processor with two MIPI CSI connectors and designed for 4K cameras. Allwinner has now come up with a new 4K camera processor very similar to V5, since Allwinner V566 comes with two Cortex-A7 cores, and a single MIPI CSI interface, and Lindenis designed a new SBC based on the new processor using a SoM + baseboard design instead. Lindenis V536 specifications: SoM SoC – Allwinner V536 dual-core Cortex-A7 processor @ 1.2 GHz; 4K H.265/H.264 video encoding & decoding @ 30 fps; 28nm process System Memory – 1GB DDR3 Storage – SPI NOR flash or SPI NAND flash, bootable MicroSD card Video Output – Micro HDMI 1.4 port Video Input – MIPI CSI connector Audio – Digital microphone Connectivity – 802.11b/g/n/ac Wi-Fi 5 & Bluetooth 4.2 via AP6255 Baseboard Interface – Castellated holes […]
