🏗️ How Zenitel TEIV-4+ Video Intercom is Made

The Zenitel TEIV-4+ Video Intercom is built through a combination of industrial electronics manufacturing, precision assembly, and strict quality testing to ensure it works reliably in demanding environments like buildings, factories, and outdoor entrances.

🧱 1. Outer Housing Manufacturing

The front housing is made from high-strength thermoplastic material, designed for durability and long-term outdoor use.

Process:

• Plastic is formed using injection moulding
• Internal structure is reinforced for strength
• Surface is treated for UV and weather resistance
• Sealing gaskets are added for waterproof protection (IP-rated design)

👉 This ensures the unit can withstand rain, dust, and impact in real-world installations.

⚙️ 2. PCB (Main Circuit Board) Production

Inside the intercom is a multi-layer PCB (Printed Circuit Board) that controls all functions.

What happens here:

• Components like microcontrollers, audio chips, and network modules are placed using SMT (Surface Mount Technology)
• The board handles:
  • Video processing
  • Audio communication
  • RFID / access integration support
  • Door relay control

👉 This is the “brain” of the intercom system.

🎧 3. Audio System Assembly

Zenitel is known for professional audio performance, so this step is critical.

Process:

• High-sensitivity microphone installed
• Loudspeaker fitted for high sound pressure output
• Audio chip tuned for:
  • Noise cancellation
  • Echo suppression
  • Automatic volume adjustment

👉 This ensures clear communication even in noisy environments.

🎥 4. Camera Integration

The HD camera module is carefully installed into the front panel.

Process:

• Wide-angle lens aligned for entry viewing
• Sensor calibrated for low-light performance
• Connected to main PCB for streaming (RTSP/SIP systems)

👉 Ensures clear visitor identification day and night.

🪪 5. RFID Card Reader Integration Space

The TEIV-4+ includes dedicated space for RFID card reader integration.

Process:

• Mounting area designed for third-party RFID modules
• Wiring interface connected to main control board
• Tested for access control response timing

👉 This allows flexible access control customization depending on project needs.

🌐 6. Firmware & Software Programming

Before assembly completion, the system is programmed with embedded software.

Includes:

• SIP communication protocol
• Door relay logic
• Audio/video processing
• System integration settings

👉 Enables compatibility with modern IP-based security systems.

🧪 7. Testing & Quality Control

Each unit goes through strict testing before release.

Tests include:

• Audio clarity check
• Video stream verification
• RFID access response test
• Door relay switching test
• Waterproof and dust resistance checks
• Network connectivity (SIP/RTSP)

👉 This ensures stable performance in real installations.

🏁 Final Assembly

All parts are assembled into a sealed unit:

• Housing closed and waterproof sealed
• PCB secured inside shock-resistant structure
• Camera and keypad aligned precisely
• Final inspection completed
