LiFi | Lighting the Way to the Future of Wireless Communication

Image
  Credits   In a world increasingly hungry for faster, more secure, and more efficient data transmission, a new contender is stepping into the spotlight—literally. Light Fidelity, or LiFi, is a cutting-edge wireless communication technology that uses light to transmit data. Imagine browsing the internet through your desk lamp or streaming 4K video via your ceiling light. Sounds futuristic? It’s already happening. What Is LiFi? LiFi stands for Light Fidelity, a form of Visible Light Communication (VLC). Unlike WiFi, which uses radio waves, LiFi transmits data using modulated light signals, typically from LED bulbs. These signals are invisible to the human eye but can be picked up by photodetectors and converted into digital information. How Does It Work? LED Light Source: LEDs are rapidly switched on and off to encode data. This flickering is imperceptible to humans. Photodetector: A receiver captures the light signals and decodes them into usable data. Bi-directional Communica...

Discover the Power of Cisco Meraki

    Cisco Meraki MX Firewalls is a Unified Threat Management (UTM) and Software-Defined WAN solution. As a UTM product, Meraki MX provides content filtering, app-specific traffic control, intrusion prevention, malware protection, and site-to-site VPN that is deployable on hardware or virtually. It also enables firewall management remotely for 24x7 monitoring and accessibility. Users are able to deploy, monitor, and configure their Meraki devices via the Meraki dashboard web interface or via APIs. Once a user makes a configuration change, the change request is sent to the Meraki cloud and is then pushed to the relevant device(s).   Meraki Cloud Architecture The Meraki cloud is the backbone of the Meraki management solution. This "cloud" is a collection of highly reliable multi-tenant servers strategically distributed around the world at Meraki data centers and select public cloud service providers. For the remainder of this document we will refer to both the Meraki...

How does Artificial Intelligence Affects Surveillance?

  The good part of AI is that it can be trained to identify and learn patterns and parameters, similar to the human brain. Machine learning and deep learning are both types of AI. With machine learning, systems embedded with AI can automatically adapt and learn from events without being explicitly programmed. However, a machine can also be trained through program settings to follow a set of rules, i.e. algorithms, to give  advanced features when it comes to security. Using behavioral analytics, a self-learning, A.I. takes the data from video cameras and continuously classifies objects and events that it sees. Take for example, a person crossing a street is one classification. A group of people is another classification. AI algorithms can effectively detect anomalies, such as unattended bags or suspicious activities, and raise alerts in real-time, significantly reducing response times. Using rule-based intelligence, AI and video analysis tools enable security teams to detect po...
