More from the Manufacturer


The Aruba 7200 series Mobility Controller is the next-generation networking platform, optimized for mobile application delivery to ensure the best mobility experience over Wi-Fi.

With a new central processor that employs eight cores with four threads each, it's like having a total of 32 virtual CPUs. As a result, the 7200 series supports 32,000 mobile devices and performs stateful firewall policy enforcement at 40 Gbps - plenty of capacity and speed for BYOD and 802.11ac devices.

New levels of visibility are provided by Aruba's unique AppRF technology, which runs on 7200 series Mobility Controllers. With AppRF, IT can see applications by user, including top web-based applications like Facebook and Box.

The 7200 series also manages authentication, encryption, VPN connections, IPv4 and IPv6 Layer 3 services, the Aruba Policy Enforcement FirewallTM, Aruba Adaptive Radio ManagementTM, and Aruba RFProtectTM spectrum analysis and wireless intrusion protection.

Clustering and centralized management enable the deployment of large networks with hundreds of Mobility Controllers with minimal staff. A master Mobility Controller can manage local Mobility Controllers, while Aruba AirWaveTM network management provides enterprise-wide clarity and control through real-time monitoring, historical reporting and troubleshooting.

Face Counting
With the embedded deep learning algorithms, the camera integrates multiple intelligences. It counts persons and samples the face features simultaneously, and compares them with the built-in face library, so to remove the duplicated person. It counts persons and reports a face alarm simultaneously to achieve both the entrance control and people counting.

Hard Hat Detection
With the embedded deep learning algorithms, the camera detects the persons in the specified region. It detects whether the person is wearing a hard hat, and captures the head of the person and reports an alarm if not.

Multi-Target-Type Detection
With the embedded deep learning algorithms, the camera detects and captures the face and human body in the specified region and outputs the features, such as gender, age and top color. It supports a structurized modeling of the face and human body to achieve a structurized data collection.

Queue Management
With embedded deep learning based algorithms, the camera detects queuing-up people number and waiting time of each person. The body feature detection algorithm helps filter out wrong targets and increase the accuracy of detection.

Metadata
Metadata uses individual instances of application data or the data content. Metadata can be used for third-party application development.

Smooth Streaming
Smooth streaming offers solutions to improve the video quality in different network conditions. For example, in poor network conditions, adapting to the detected real-time network condition, streaming bit rate and resolution are automatically adjusted to avoid mosaic and lower latency in live view; in multiplayer network conditions, the camera transmits the redundant data for the self-error correcting in back-end device, so that to solve the mosaic problem because of the packet loss and error rate.

Anti-Corrosion Coating(-Y)
The camera adopts high weatherproof and wearproof molding powder that confirms to AAMA2604-02 and Qualicoat (Class2) specifications, and uses two-layer special spraying technology, so its surface has excellent long-term anti-corrosion performance and physical protection function. Besides, all the exposed screws use SUS316 material and features high anti-corrosion performance. Therefore, the whole camera meets anti-corrosion requirements NEMA 250-2018.

The 55" NEC E558, a direct-lit, commercial-grade display, is ideal for education, corporate and other digital signage applications. Compared to previous generation displays, this model's 4K UHD resolution and LED direct backlighting allows for higher visual acuity, reduced power consumption and localized dimming that gives a higher dynamic contrast ratio.The E558 has an integrated ATSC/NTSC tuner and dual 10W speakers allow users to enjoy high-definition broadcast capabilities. This display also features a USB player in which video, audio or JPEG picture files can be loaded and played in sequence for signage purposes.

  • Tilt back and forth installation (-10°?10°) to install it at desired angle
  • New temperature and ambient light sensors

Features & Design | An AC adapter with a smart design

Powerful efficiency: Increase processing speeds with the high-power 360W 7.4mm GaN Slim Adapter from Dell. Featuring gallium nitride (GaN) technology, it's capable of more efficient current flow thanks to its smaller and lighter form factor.

Intelligent design: Reduce your personal carbon footprint with your smaller adapter. The GaN-based design features 40-50% less chassis volume which produces less heat and is made with post-recycled materials.

Convenient connectivity: Run your system and charge your battery at the same time with 360W of power delivery. This adapter comes bundled with a 3ft (1m) power cord and rubber strap for easy cable management, with an LED light ring on the DC connector.
