Omnivision and iCatch ring the changes with edge AI video doorbell

Enhancing video doorbell technology, Omnivision and iCatch Technology have partnered to introduce a colour pre-roll feature into home security cameras. The partners have integrated Omnivision’s OA07600 low power, always-on video co-processor with a pre-roll recording buffer and iCatch Technology’s Vi57 AI imaging SoC to introduced colour pre-roll capability to wireless home security products. This features enables users to save up to four seconds of video footage prior to the camera’s motion detector triggering.

David Ho, technical director of product management at Omnivision said: “The OA07600 is the industry’s first ultra-low power, always-on video co-processor with pre-roll”. He said the co-processor’s low power design “makes it possible for the first time to bring high-quality pre-roll video into battery-powered systems”. 

Continuous storage of pre-event colour video footage in the integrated chipset bring “exceptional traceability and visibility” during any trigger event, said Omnivision.

iCatch Technology’s Vi57 imaging SoC has fast capture and edge AI capability to improve the general usability of video doorbells. Taking the pre-roll footage from Omnivision’s OA07600 co-processor, the Vi57 SoC can seamlessly combine it with post-event footage into one video with minimal data loss. The image processing capability means that the SoC is capable of providing high quality video in full colour, even under extreme low light conditions, said the company. The introduction of colour information can be used to provide users with a better understanding and enhanced traceability of the incident.

Weber Hsu, CEO of iCatch technology said that the collaboration means the partners are “closing the gap of the user experience between wired and wireless home security cameras, offering both ease of installation and incident traceability at the same time”.

The colour pre-roll video doorbell solution jointly developed by iCatch Technology and Omnivision is in mass production now and available for customer engagement.

Citizen radio is used for backhaul of LoRaWAN gateway traffic

Industrial IoT gateway company AMIT Wireless, and IoT connectivity company, Actility, have partnered to facilitate deployment of CBRS (Citizens Broadband Radio Service) IoT use cases for backhauling LoRaWAN gateway traffic.

CBRS was launched in the USA in 2020 by the FCC as a dynamic sharing system in the 3550 to 3700MHz band. Also known as the innovation band, this frequency band will allow for the expansion of coverage and capacity of operators’ LTE services as well as the implementation of new mobile uses (e.g., 5G and IoT). The band is currently also used by the US Navy, the Department of Defence and satellite communication service providers.

AMIT and Actility have agreed co-operation and mutual promotion of the AMIT Wireless CBRS products as a backhaul for LoRaWAN gateways using Actility’s ThingPark IoT platform, opening up a range of use cases to allow the deployment of private cellular network in CBRS bands.

One of the main challenges for IIoT LoRaWAN deployments in rural or remote areas is backhaul connectivity. Private cellular networks are privately owned, customisable cellular networks comprised of various components such as radio hardware and network orchestration software. These networks can significantly enhance connectivity and address the limitations of traditional Wi-Fi networks in industrial IoT deployments in remote areas. Public cellular networks, in contrast, provide limited control over service quality and risk data security, explained Actility. The solution, said AMIT and Actility is for the AMIT Wireless CBRS LTE devices to carry the backhaul traffic of LoRaWAN gateways.

The FCC’s decision to allocate more spectrum for business use, enterprises can now construct and operate their own private LTE or 5G networks, tailored to their needs, said Actility.

The Actility ThingPark Market presents a trial kit to demonstrate the capabilities of private LTE CBRS networks. The kit is characterised by the ability to enable roaming over CBRS and public networks using a single ThingPark global SIM card, as a result of global agreements with public network operators.

This kit illustrates a typical CBRS use case, providing backhaul for LoRaWAN gateways in rural or industrial networks, which traditionally rely on public SIMs, Ethernet or satellite connectivity. The kit can also be used to explore other CBRS use cases. Combined with AMIT Wireless CBRS gateways, it extends more possibilities by cellular connections and is also claimed to make users’ deployment easy, secure and reliable.

Dev kit for LTE IoT eliminates certification process

The Digi XBee 3 Global GNSS LTE CAT 1 development kit can help engineers accelerate time to market and quickly integrate LTE cellular into devices and applications, eliminating the FCC and carrier end device certification process.
The kit is available from Mouser Electronics and includes the Digi XBee 3 Global LTE Cat 1 embedded modem and is pre-loaded with three months of pre-activiated cellular data service. The modem provides the flexibility to switch between multiple frequencies and wireless protocols as needed. These pre-certified Global LTE Cat 1 modules are suitable for moderate bandwidth (typically less than 25Mbyte per month) and low cost IoT applications, advised the company.
Pairing Digi Remote Manager with the XBee 3 Global LTE Cat 1 modem allows users to configure and control the modem from a central platform. The built-in Digi TrustFence security, identity, and data privacy features use multiple control layers to protect against new and evolving cyber threats.
Onboard templates can prototype cellular integration while the full suite of standard Digi XBee API frames and AT commands, MicroPython, and Digi XCTU allows users to seamlessly transition to this embedded modem with only minor software adjustments, said Mouser. Standard XBee API frames and AT commands, MicroPython, and  XCTU simplify setup, configuration, testing and adding or changing functionality.

VCSEL-based reflective optical sensor saves space

The VCNT2030 reflective optical sensor by Vishay Semiconductors, is offered in a compact surface mount package measuring just 1.85 x 1.2 x 0.6mm.
The sensor is suitable for industrial, computer, consumer, and mobility applications. They save space, compared to previous generation sensor and deliver a higher current transfer ratio (CTR), increased sensing distance and lower power consumption, said the company.
The Vishay Semiconductors VCNT2030 features a VCSEL (vertical cavity surface emitting laser) and a silicon phototransistor in the miniature package. It is compact in construction with the emitting light source and detector arranged in the same plane. It also offers excellent internal crosstalk suppression due to the VCSEL’s narrow ±17 degree emission angle, which also enables improved proximity performance behind cover glass. The VCNT2030’s analogue output signal at the phototransistor is dependent on the amount of light emitted by the VCSEL and reflected off an object in the sensor’s field of view. The device offers a sensing distance of 15mm, which is three times higher than the closest competing device on the market, claimed Vishay.
The compact footprint saves at least 40 per cent of PCB space compared to previous generation devices, said Vishay. As a result, the sensor saves space in optical switching applications in industrial infrastructure, home and building controls, notebook and desktop computers, home appliances, consumer electronics and metering applications. It can also be used in optical encoding for motor control in e-bikes, golf carts, tractors, and harvesters, as well as detecting paper presence in printers and scanners. In these applications the low 8mA driving current of the device’s VCSEL is sufficient to achieve the same performance as solutions using 20mA infrared emitters, which lowers power consumption.
The sensor offers a detection range of 0.3 to 6.0mm, an emitter wavelength of 940nm and a typical output current of 2.5mA, which represents a typical CTR of 31 per cent under test conditions. This value is more than 100 per cent higher than previous generation solutions and the closest competing sensor, said Vishay.
The VCNT2030 features a Moisture Sensitivity Level (MSL) of 3 for reflow soldering according to J-STD-020. It is RoHS-compliant and halogen-free.
Samples and production quantities of the VCNT2030 are available now, with lead times of eight to 16 weeks.
