Hikvision, global provider of innovative security products and solutions, has introduced its Video & Audio Convergence Solution to the market, featuring an innovative real-time intrusion deterrent feature.

With Hikvision’s new Video & Audio Convergence Solution, IP speakers now can be linked with cameras, access control systems, and alarm devices. When the CCTV system automatically detects an intrusion or if the alarm system is activated, IP speakers can immediately play programmed audio warnings to drive away would-be intruders.

CCTV systems and IP cameras

Efficient security operations and digital transformation are supported by alarm video that can pop up automatically

The audio message acts as a deterrent to possible intrusion actions as they happen. Loss and damage can be prevented, and footage of the event gets recorded for investigation and evidence collection. Along with imported audio warnings, operators can also speak via the IP speakers to give live warnings when notified of an intrusion. Efficient security operations and digital transformation are further supported by alarm video which can pop up automatically.

Scheduled audio messaging and public information broadcasting are two more practical functions made possible by Hikvision’s Video & Audio Convergence Solution. IP speakers can play recorded audio recordings according to a schedule, and operators can use the audio system to broadcast public information as needed to audiences as well.

Video & Audio Convergence Solution

Frank Zhang, General Manager of the International Product Marketing Department at Hikvision says, “We are excited to introduce our innovative Video & Audio Convergence Solution to the market. With the linkage between video and audio, our solution will empower security systems with cautionary and immediate processing abilities. We believe convergence will be a new trend in the near-future for the security industry.

With its valuable functionality, Hikvision Video & Audio Convergence can be applied across a wide range of scenarios and applications – including perimeter security, petrol stations, metro and railway stations, office buildings, and much more. Continue reading for more details on various applications.

Perimeter Security

In luxury homes equipped with outdoor CCTV cameras, trespassers will be recorded by security cameras and NVRs, but no immediate deterrent actions can be taken.

Now with the Hikvision Video & Audio Convergence Solution, audio warnings can be automatically triggered to deter intruders, helping to prevent loss of property or more serious incidents.

Intelligent detection function

Petrol stations are vulnerable to intrusions during non-business hours and damage to petrol storage facilities

Petrol stations are vulnerable to intrusions during non-business hours and damage to petrol storage facilities can cause disasters. Currently, with CCTV systems alone, no immediate action can be taken when an intrusion occurs. But the Hikvision Video & Audio Convergence Solution now provides an intelligent detection function, alarm triggering, and audio warnings.

At petrol stations with self-payment systems but no outside service staff, the Hikvision Video & Audio Convergence Solution enables operators to speak to customers remotely via the IP speakers. They can help customers and prevent security incidents without putting themselves in danger. And in emergency situations, the audio system can be used to broadcast critical information to staff and customers.

Metro and Railway Stations

Platforms are dangerous during peak hours when passengers cross warning lines and move too close to the edge. The Hikvision Video & Audio Convergence Solution helps monitor people flow and can identify when passengers cross warning lines. Staff can use the solution to broadcast live audio warnings and train schedule information whenever it’s needed.

Office Buildings

CCTV and access control systems are commonly used in office buildings. However, when an intrusion or security anomaly has been detected, operators rely on sending on-site guards to check the situation. Efficiency is low and guards often arrive too late to prevent an incident.

In such a case, Hikvision’s Video & Audio Convergence Solution can send an immediate audio warning to deter an intrusion, as well as build video and audio linkage for operators to check remotely via live view. Similarly, during emergency situations, security operators can use the audio system to broadcast information to people inside a building.

How should the security industry promote diversity?
How should the security industry promote diversity?

Diversity in a company’s workforce is arguably more important now than ever. Societal awareness of the importance of diversity has grown, and many people see diversity as an important factor that reflects positively (or negatively) on a company’s culture and image in the marketplace. We asked this week’s Expert Panel Roundtable: What should the security industry do to promote workplace diversity?

Why face recognition as a credential is the ideal choice for access control?
Why face recognition as a credential is the ideal choice for access control?

In the field of access control, face recognition has come a long way. Once considered too slow to authenticate people's identities and credentials in high traffic conditions, face recognition technology has evolved to become one of the quickest, most effective access control identity authentication solutions across all industries. Advancements in artificial intelligence and advanced neural network (ANN) technology from industry leaders like Intel have improved the accuracy and efficiency of face recognition. However, another reason the technology is gaining traction is due to the swiftly rising demand for touchless access control solutions that can help mitigate the spread of disease in public spaces. Effective for high volumes Face recognition eliminates security risks and is also virtually impossible to counterfeit Modern face recognition technology meets all the criteria for becoming the go-to solution for frictionless access control. It provides an accurate, non-invasive means of authenticating people's identities in high-traffic areas, including multi-tenant office buildings, industrial sites, and factories where multiple shifts per day are common. Typical electronic access control systems rely on people providing physical credentials, such as proximity cards, key fobs, or Bluetooth-enabled mobile phones, all of which can be misplaced, lost, or stolen. Face recognition eliminates these security risks and is also virtually impossible to counterfeit. Affordable biometric option Although there are other biometric tools available, face recognition offers significant advantages. Some technologies use hand geometry or iris scans, for example, but these options are generally slower and more expensive. This makes face recognition a natural application for day-to-day access control activities, including chronicling time and attendance for large workforces at construction sites, warehouses, and agricultural and mining operations. In addition to verifying personal credentials, face recognition can also identify whether an individual is wearing a facial covering in compliance with government or corporate mandates regarding health safety protocols. Beyond securing physical locations, face recognition can also be used to manage access to computers, as well as specialised equipment and devices. Overcoming challenges with AI So how did face recognition become so reliable when the technology was once dogged by many challenges, including difficulties with camera angles, certain types of facial expressions, and diverse lighting conditions? Thanks to the emergence of so-called "convolutional" neural network-based algorithms, engineers have been able to overcome these roadblocks. SecurOS FaceX face recognition solution FaceX is powered by neural networks and machine learning which makes it capable of authenticating a wide range of faces One joint effort between New Jersey-based Intelligent Security Systems (ISS) and tech giant Intel has created the SecurOS FaceX face recognition solution. FaceX is powered by neural networks and machine learning which makes it capable of authenticating a wide range of faces and facial expressions, including those captured under changing light, at different resolution levels, and varying distances from the video camera. Secure video management system A common face recognition system deployment begins with IP video cameras that feed footage into a secure video management system connected to a video archive. When the software initially enrolls a person’s face, it creates a "digital descriptor" that is stored as a numeric code that will forever be associated with one identity. The system encrypts and stores these numeric codes in a SQL database. For the sake of convenience and cost savings, the video server CPU performs all neural network processes without requiring any special GPU cards. Unique digital identifiers The next step involves correlating faces captured in a video recording with their unique digital descriptors on file. The system can compare newly captured images against large databases of known individuals or faces captured from video streams. Face recognition technology can provide multi-factor authentication, searching watchlists for specific types of features, such as age, hair colour, gender, ethnicity, facial hair, glasses, headwear, and other identifying characteristics including bald spots. Robust encryption SED-compatible drives rely on dedicated chips that encrypt data with AES-128 or AES-256 To support privacy concerns, the entire system features an encrypted and secure login process that prevents unauthorized access to both the database and the archive. An additional layer of encryption is available through the use of Self-Encrypting Drives (SEDs) that hold video recordings and metadata. SED-compatible drives rely on dedicated chips that encrypt data with AES-128 or AES-256 (short for Advanced Encryption Standard). Anti-spoofing safeguards How do face recognition systems handle people who try to trick the system by wearing a costume mask or holding up a picture to hide their faces? FaceX from ISS, for example, includes anti-spoofing capabilities that essentially check for the "liveliness" of a given face. The algorithm can easily flag the flat, two-dimensional nature of a face mask, printed photo, or image on a mobile phone and issue a "spoof" alarm. Increased speed of entry Incorporating facial recognition into existing access control systems is straightforward and cost-effective Incorporating facial recognition into existing access control systems is straightforward and cost-effective. Systems can operate with off-the-shelf security cameras and computers. Users can also leverage existing infrastructure to maintain building aesthetics. A face recognition system can complete the process of detection and recognition in an instant, opening a door or turnstile in less than 500ms. Such efficiency can eliminate hours associated with security personnel checking and managing credentials manually. A vital tool Modern face recognition solutions are infinitely scalable to accommodate global enterprises. As a result, face recognition as a credential is increasingly being implemented for a wide range of applications that transcend traditional access control and physical security to include health safety and workforce management. All these capabilities make face recognition a natural, frictionless solution for managing access control, both in terms of performance and cost.
