C4ISR stands for Command, Control, Communications, Computing, Intelligence, Security and Reconnaissance. It was formulated by the US Department of Defense (DoD) in response to the need to evolve a mechanism for integrating and acting on combat information coming from various sources, geographies, and using different types of media.

A C4ISR System can be thought of as a framework for organizing multi-media information emanating from a situation (typically a crisis), in a manner that enables non-local users to analyze such information (from multiple sources); act on that information or advise local players on actions to be taken; receive feedback from local players on actions taken; based on which a follow-up set of actions or advice can be initiated, towards the objective of resolving the situation to the advantage of the users.

Traffic management systems

C4ISR has been adapted, from its military origins, for Homeland Security given the similarity in the situations faced by a city reeling from a terrorist strike or a major conflagration, and an army battalion in hostile action. Subsequently, the concept has been applied to systems that involve co-ordination among multiple agencies, function in an environment which is in a state of constant flux, and are given the responsibility of addressing crises (albeit not of the type resulting in major fatalities).

Traffic management systems in India have relied on components such as sensors

City-wide traffic management is one such system, internationally, where C4ISR concepts have been applied. Traditionally, traffic management systems in India have relied on components such as sensors, communication networks, control centers, response team.

New sensor technologies

Implementing a traffic management system on a C4ISR framework, will allow traffic managers to optimize the data coming in from existing sensors and field units, through fusion of the data on a visual representation of the city.

  • Integration of sensor data streams in the GIS - Traffic managers will be able to integrate surveillance and enforcement camera feeds into the Traffic Management GIS. Typically, such a GIS will have an overlay consisting of traffic light junctions in the city, and key emergency features (hospitals, police stations, fire stations, etc.). Using a C4ISR application, camera feed from a specific traffic junction can be embedded in the GIS, so that a click on that traffic light icon, on the GIS, displays live video stream from the cameras positioned at that junction. This feature can be enabled for any sensor data stream.
  • Integration of multi-media information in the EMS - Voice and data communications, from motorists and field units, can be fed into the C4ISR application and associated with an incident or location, so that clicking on that incident/location, brings up all recorded information associated with that incident/location. This Common Operational Picture (COP) approach to analyzing situations is unique to C4ISR solutions.
  • Multiple communications protocols communicating seamlessly - Patches between multiple communications protocols (GSM, CDMA, U/V/HF, PSTN, Tetra, etc.) seamlessly, thereby allowing traffic teams to communicate with the TMC and amongst themselves using a variety of communication Also patches motorists, providing eye-witness information, communication to relevant field units.
  • Broadcast traffic control messages/signals in real-time - Co-ordinate output to a VMS, traffic signals (if they can be centrally controlled), and citizen database (SMSes regarding traffic jams, etc.) within a short time of the occurrence of an emergency. Databases can be linked to the C4ISR application, so that specific actions can be performed on a database.
  • Blue force tracking for field units - Optionally, provide GPS-enabled devices to all or key traffic personnel/response teams so that real-time monitoring of response to emergencies is possible. The GPS devices allow field units to be mapped on the GIS in real-time.
  • Risk & action protocols - Co-ordinate response to traffic problems and other emergencies (that may create traffic problems or may be exacerbated by traffic problems) in a planned manner, using all the media tools available to the crisis response team. SOPs can be defined for various situations and entered in the C4ISR application, so that when an emergency occurs, even inexperienced personnel can take control.
  • Integrate new sensor technologies as they are introduced - With increasing traffic and larger road networks, more sophisticated sensors will need to be deployed: traffic radar sensors, single/double loop detectors, etc. A C4ISR solution will allow data feeds from these sensors to be integrated with those from existing sensors.

Mistral offers a range of C4ISR solutions for Homeland Security needs in India. These solutions will allow traffic managers to further leverage existing investments in sensors and IT, towards making the roads safer and traffic smoother.

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.

Hikvision Ensures Building-Wide Security And Optimising Parking Flow For Luxury Four-Star Hotel In Kigali
Hikvision Ensures Building-Wide Security And Optimising Parking Flow For Luxury Four-Star Hotel In Kigali

Security monitoring, intrusion detection, parking management, one installation of Hikvision technology can do all this, and more. Discover how the 2000 Hotel in Kigali is using Hikvision technology to make operations more secure and efficient on every floor of its luxury four-star accommodation. The 2000 Hotel in Kigali, Rwanda, is known as the ‘highest hotel in Kigali’, offering captivating views over the city and the mountains. Guests enjoy the hotel’s four-star luxury facilities for work and leisure, taking advantage of its central location in the heart of Rwanda’s bustling capital city. Security of hotel guests has always been paramount, and so soon after the hotel was built, the management team installed security cameras throughout. However, over time it turned out that the imagery captured simply wasn’t clear enough to be useful in many situations. Underground parking lot Unfortunately, we started to notice that goods were going missing in the supermarket, as well as in the warehouse" What’s more, there were further security issues following the opening of a new supermarket on the hotel’s second floor. “Unfortunately, we started to notice that goods were going missing in the supermarket, as well as in the warehouse,” explains Miao Zhang, the Managing Director, 2000 Hotel. “Sometimes we noticed cash was missing from the registers, too.” In addition to this, the hotel was seeking a more efficient way to manage its underground parking lot. “The hotel was using a guard to let people in and out of the parking lot, and to calculate payments. But with more than 500 spaces to look after, this took time, often causing traffic jams as visitors waited to leave. Plus, the parking fees were sometimes incorrect,” explains Jaden. “Consequently, the team decided to explore how technology might be able to help.” Intrusion alarm system The 2000 Hotel chose a complete Hikvision solution, featuring 70 security cameras, a 60-channel intrusion alarm system for the supermarket, and an entrance/exit and payment system for the parking lot. In the corridors of the hotel and in the supermarket, the team installed Hikvision Dome Network Cameras (DS-2CD2145FWD-I). These discreet cameras offer high-quality images, even in low light conditions. In the hotel lobby, the stairwells and in the supermarket, the team installed Hikvision Bullet Network Cameras (DS-2CD2T45FWD-I5), with extended zoom and infrared capabilities that are ideal for these larger spaces. At the supermarket checkouts, the team installed Hikvision Varifocal Bullet Network Cameras (DS-2CD2645FWD-IZS), which feature a motorised varifocal lens for close monitoring of this busy location. Varifocal IR bullet cameras Meanwhile, Hikvision Varifocal IR DarkFighter Bullet Cameras (DS-2CD5A26G0-IZS) were installed at the main entrance of the hotel and the supermarket. These feature a wide dynamic range, ensuring clear images even when the cameras are facing strong light. To protect the supermarket outside of opening hours, the 2000 Hotel installed a complete Hikvision intrusion alarm system. The alarm system contains a PIR sensor (DS-PD2-D15AME), which is installed near the window of the supermarket. If someone intrudes in from the window at night, the system will be triggered and an alarm will be issued. Not only that, there is also a panic alarm station (DS-PEA1-21) in the control room of the supermarket. If an emergency occurs, people can use the tool to realise alarm aid at the first time. ANPR video unit The 2000 Hotel is managing the whole solution through Hikvision IVMS-5200E software Finally, at the entrance and exit of the underground parking lot, the hotel installed the Hikvision ANPR Video Unit (DS-TCG227-A), along with barriers, a card station and an integrated payment system, also from Hikvision. The 2000 Hotel is managing the whole solution through Hikvision IVMS-5200E software. Thanks to the high quality Hikvision technology, live review is very clear, making it ideal to support the investigation of any security incidents. However, since cameras were installed, there have been fewer incidents to deal with. What’s more, the supermarket team are better equipped to respond in the event of an out-of-hours breach. “If an intruder triggers the alarm, the duty manager gets an instant alert on their phone with quick access to relevant footage. This gives them real peace of mind,” says Jaden Huang, the Project Manager from Hikvision. “Indeed, it’s possible to view the status of the whole hotel system from a laptop or phone.” Parking management solution Down in the basement parking lot, the Hikvision parking management solution is working effectively. “Parking has become faster and more automated. For example, barriers will open and close automatically when customers take or insert a card, and parking charges are automatically calculated. And there are no more jams on exit,” confirms Jaden. The 2000 Hotel team are working on a new building in Kigali, with construction almost completed. The plan is to use Hikvision technology here, too. Miao says “Hikvision has provided the 2000 Hotel in Rwanda with world-class video technology that solved a host of our security and operational challenges. They also offer excellent support in one centralised location. We fully appreciate their professional service, and look forward to continuing our working relationship.”
