CIT Connect Terminal 🎓

CIT Connect Terminal is a highly secure, real-time video and chat routing platform built exclusively for the students of Chennai Institute of Technology (@citchennai.net / .edu). It features a "Stranger-Match" WebRTC engine, encrypted chat channels, and an incredibly powerful System Administrator Overwatch Dashboard designed for full network moderation and forensic tracking.

⚡ Core Features

1. 🛡️ Absolute Access Control

• Domain Whitelisting: Powered by a robust Regex system that physically prevents any email without the precise [name].[dept][year]@citchennai.net format from accessing the handshake arrays.
• Autofill Protection: Prevents browser-saved passwords and random auto-fills from crashing the verification logic.

2. 📹 High-Performance WebRTC Media Engine

• Fluid Video Delivery: Hardware constraints actively force a pure 1280x720p @ 30FPS pipeline out of the user's camera to guarantee maximum clarity.
• Background Anti-Freeze Daemon: An intrinsic loop scans the remoteVideo tracker every 2000 milliseconds. If it detects that a mobile device has jittered/frozen the frame decode, it dynamically flushes the rendering tag without dropping the call to instantly un-stick the stream.
• Smart Queue Reconnection: When you hit "NEXT STRANGER", the server evaluates the entire socket pool. If only 2 people are online, it instantly reconnects you locally. If there are massive pools, it activates a 2-second timeout barrier coupled with a randomized selector to ensure you never get stuck looping on the same person.

3. 💬 Secure P2P Communications

• WhatsApp-Style Read Receipts: Tracks messages structurally. When a message/file is sent, it triggers a grey ✓. The millisecond the recipient's browser processes the payload, a chat_received bounce-back fires across the server and structurally updates your screen to blue ✓✓ ticks.
• Heavy Data File Transfers: Uses embedded FileReader APIs hooked directly into a scaled up 10MB maxHttpBufferSize socket framework. Safely share PDFs, assignment files, or ZIPs up to 8MB, while natively parsing and framing inline Images straight into the chat!

4. 👁️ The System Overwatch Dashboard (Admin Mode)

Built entirely independently but securely bridged into the main system. Accessed securely via strict Root passwords.

• Zero-Latency Feed Intercepts: Users stream heavily compressed ultra-fast JPEGs (5 frames per second) backward into the Admin Dashboard allowing the admins to monitor everyone currently online smoothly without disrupting the user's main WebRTC pipeline.
• Automated Face Capture Integration: Exactly 1.5 seconds after a user turns on their camera, a hidden HTML5 Canvas dynamically snapshots the frame, encodes it, and permanently bolts their "Mugshot" securely onto their login record.
• Deep Forensic Tracking: Logs exactly who connected (parsing their Name, Dept, Year), logs their literal Network IP Address via headers, identifies their exact Operating System/Device string, and timestamps the second they entered.
• Live Action Systems: Admins can instantly Kick abusive users straight off the socket grid, or read real-time Reports generated remotely.
• Hardware Export Arrays: Admins can hit 1 button to extract the entire server history as unstructured JSON, Excel-ready CSV, or a highly-stylized Auto-Printing native PDF table.

🛠️ Technology Stack

• Backend Frame: Node.js utilizing Express.js to serve static pages smoothly over standard Ngrok configurations.
• Real-time Pipeline: Socket.IO configured with custom room architecture (io.to('admins')), asynchronous state mapping (users / waitingQueue), and high-speed data payload limit overrides.
• Frontend Architecture: Pure minimal HTML5/CSS3 leveraging Modern CSS Variables (--primary, --magenta), Flexbox, dynamic DOM element manipulation and native browser mediaDevices APIs.
• Identity Styling: Responsive scaling ensuring mobile UI views are strictly proportionate to massive Desktop admin Dashboards without glitching.
