ARST is a public transportation company in Cagliari, Italy. The company operates a massive fleet of about 800 public buses throughout the island of Sardinia. During the vehicle modernization process, the company decided to deploy new centralized CCTV systems to enhance the security level of passengers and drivers.


First of all, the low-definition images captured by the original surveillance equipment cannot meet the company’s advanced monitoring needs. Second, the bus driver could not achieve point-to-point communication with the command center in real-time. In addition, in case of an accident, there was no emergency button on the bus before to report the emergency to the command center.


To help ARST revamp its bus security system, a customized Dahua mobile solution consisting of more than 3,000 cameras and 750 MXVRs, Panic Buttons, DSS integrated platform as well as other accessories was employed. The data collected from the front-end cameras are integrated in the control room via DSS4004, where emergency calls, geo-localization of vehicles, and statistics can be managed.

Video recorder

MXVR6212 supports real-time vehicle location tracking and monitoring, GPS and video can be uploaded via a wireless network Each bus is equipped with a Penta-hybrid video recorder MXVR6212, 4, 6, or 8 HAC-HDBW2241F cameras and panic buttons. The main features of the systems are data encryption, people counting, hot spot, router 3G/4G, dynamic management of the LCD monitor on board, and geo-localization via the DSS app.

As the first mobile XVR adopting HDCVI/AHD/TVI/CVBS/IP signals, MXVR6212 can achieve 1080P high-definition real-time recording. It supports real-time vehicle location tracking and monitoring, and all information such as GPS and video can be uploaded via a wireless network – 3G/4G/WIFI. In addition, the device can also support the connection of various accessories, such as card readers, fuel sensors, and emergency buttons. Furthermore, it has passed EN50155/ISO16750 to meet the requirements for mobile use. Other than the city bus, this device can be used in various applications, such as school buses, taxis, police cars, trains, trucks, etc.

Mobile camera

The 2MP HAC-HDBW2241F-M-A mobile camera is designed with a shock-proof compact case, which makes it convenient to be installed and adaptable to various applications. Boasting the strengths of the Dahua self-developed HDCVI technology, the camera offers high-quality images and ensures real-time transmission. Also, it adopts a high-performance sensor to provide incomparable performance even under extreme lowlight environment. The Starlight feature allows capturing of more details and recognizing accurate colors at night or in scenes with limited illumination.

DSS platform

At the control room, Dahua DSS platform was utilized to control and manage the mobile devices deployed on the bus. It displays real-time location, speed, direction of mobile device, playback device’s history location, and supports alarm for over-speeding, entering, and leaving the E-FENCE. Aside from central management, the Business Intelligence feature of Dahua DSS platform also allows the user to export Heat Map reports and people counting statistics, helping operator companies to optimize the driving route to generate more profit.


With upgraded Dahua system, the command center can communicate with every single vehicle of ARST Bus Company in real-time, enabling them to deliver instructions to the driver, allowing the driver to report immediately to the command center in case of an emergency through the panic button, and ensuring the safety of passengers and drivers.

The Dahua mobile solution with high-definition monitoring performance reduces theft and robbery on buses and enables bus companies to collect accurate information about traffic flows and automatically download data to assist efficient and profitable operations.

The Dahua mobile solution mounted onboard has been proven to be highly efficient and reliable, which were also applied in two other Italian bus companies: AMAT Bus Company in Taranto and AMTAB Bus Company in Bari.

What New Technologies And Trends Will Shape Video Analytics?
What New Technologies And Trends Will Shape Video Analytics?

The topic of video analytics has been talked and written about for decades, and yet is still one of the cutting-edge themes in the physical security industry. Some say yesterday’s analytics systems tended to overpromise and underdeliver, and there are still some skeptics. However, newer technologies such as artificial intelligence (AI) are reinvigorating the sector and enabling it to finally live up to its promise. We asked this week’s Expert Panel Roundtable: What new technologies and trends will shape video analytics in 2021?

Tackling The Challenge Of The Growing Cybersecurity Gap
Tackling The Challenge Of The Growing Cybersecurity Gap

The SolarWinds cyberattack of 2020 was cited by security experts as “one of the potentially largest penetrations of Western governments” since the Cold War. This attack put cybersecurity front and center on people’s minds again. Hacking communication protocol The attack targeted the US government and reportedly compromised the treasury and commerce departments and Homeland Security. What’s interesting about the SolarWinds attack is that it was caused by the exploitation of a hacker who injected a backdoor communications protocol.  This means that months ahead of the attack, hackers broke into SolarWinds systems and added malicious code into the company’s software development system. Later on, updates being pushed out included the malicious code, creating a backdoor communication for the hackers to use. Once a body is hacked, access can be gained to many. An explosion of network devices What has made the threat of cyberattacks much more prominent these days has been IT's growth in the last 20 years, notably cheaper and cheaper IoT devices. This has led to an explosion of network devices. IT spending has never really matched the pace of hardware and software growth Compounding this issue is that IT spending has never really matched the pace of hardware and software growth. Inevitably, leading to vulnerabilities, limited IT resources, and an increase in IoT devices get more attention from would-be hackers. Bridging the cybersecurity gap In the author’s view, this is the main reason why the cybersecurity gap is growing. This is because it inevitably boils down to counter-strike versus counter-strike. IT teams plug holes, and hackers find new ones, that is never going to stop. The companies must continue fighting cyber threats by developing new ways of protecting through in-house testing, security best practice sources, and both market and customer leads. End-user awareness One of the key battlegrounds here is the education of end-users. This is an area where the battle is being won at present, in the author’s opinion. End-users awareness of cybersecurity is increasing. It is crucial to educate end-users on what IoT devices are available, how they are configured, how to enable it effectively, and critically, how to use it correctly and safely. Physical security network A valuable product that tackles cybersecurity is, of course, Razberi Monitor™, which is new to ComNet’s portfolio.

Will Airport Security’s Pandemic Measures Lead To Permanent Changes?
Will Airport Security’s Pandemic Measures Lead To Permanent Changes?

Travel volumes at airports have been increasing of late, although still below the 2.5 million or so passengers the Transportation Security Administration (TSA) screened every day, on average, before the pandemic. As passengers return, they will notice the airport security experience has changed during the pandemic – and many of the changes are likely to continue even longer. Need for touchless technology The lowest U.S. air travel volume in history was recorded last April, with approximately 87,500 passengers. As passenger traffic plummeted, the aviation community sought to explore the potential of new technologies to make security checkpoints more contactless and flexible when the traffic numbers return. The pandemic has seen an increase in touchless technology deployed in the screening area. Used for cabin baggage screening, Computed Tomography (CT) produces high-quality, 3-D images to enable a more thorough analysis of a bag’s contents. Imaging Technology Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method Enhanced Advanced Imaging Technology (eAIT), which uses non-ionizing radio-frequency energy in the millimeter spectrum, safely screens passengers without physical contact for threats such as weapons and explosives, which may be hidden under a passenger’s clothing. Millimeter-wave body scanners began replacing metal detectors globally as a primary screening method.  AI algorithms Other innovations include an automatic screening lane, centralized image processing, and artificial intelligence (AI). Looking ahead, AI algorithms have the ability to clear most passengers and bags automatically, making the process smoother and freeing up staff to focus only on alarms. The pandemic’s need for contactless screening may accelerate the adoption of AI.   CAT machine Credential Authentication Technology (CAT) machines automatically verify identification documents presented by passengers during the screening process. The TSA continues to accept expired Driver’s Licenses and state-issued IDs for up to a year after expiration, based on the premise that license renewals may be delayed and/or more difficult during the pandemic. The REAL ID enforcement deadline was extended to Oct. 1, 2021.  Health precautions Checkpoint health precautions have been a part of the airport screening experience since early in the pandemic. Last summer, the TSA announced the “Stay Healthy. Stay Secure” campaign, which included requirements such as social distancing among travelers, ID verification without physical contact, plastic shielding installed at various locations, and increased cleaning and disinfecting. In January 2021, President Biden signed an Executive Order requiring travelers to wear face masks when in airports and other transportation facilities (to remain in effect until May 11). Checkpoint screening Clear is a privately owned company that provides expedited security that uses biometrics either a person’s eyes or face to speed along the process of getting people through checkpoints. TSA officers wear masks and gloves at checkpoints and may also wear eye protection or clear plastic face shields. The limits on allowable liquids a passenger may take on board were broadened to include a hand sanitizer container of up to 12 ounces, one per passenger in a carry-on bag. a paradigm shift Just as aviation security changed after 9/11, the COVID-19 crisis is expected to lead to a paradigm shift to create a safer and more secure environment. Measures were implemented so that passengers, staff and other stakeholders could have continued assurance and confidence in airports amid and after the pandemic.
