Starlight Night Vision Technology:
Empowers cameras to capture high-definition color imaging in near-darkness (0.001 lux). Maintains clear visibility of critical details like vehicles, streetlights, and environmental features even under ultra-low illumination, eliminating traditional monochrome night vision limitations.
Key Advantages:
►Full-color imaging in extreme low-light conditions
►Enhanced object recognition 
►0.001 lux minimum illumination threshold

AHD Technical Highlights:
►HD real-time transmission (25fps@1080P/720P)
►500m coaxial cable transmission range
►Seamless integration with legacy analog systems
►<1ms latency for mission-critical monitoring

Q1: No Signal/Black Screen Detection
Symptoms:
“No Signal” alert
Persistent black screen
Troubleshooting Protocol:
► Power Verification
Confirm 12V DC power delivery to camera (test with multimeter at B+ terminal)
Bypass vehicle wiring: Connect directly to battery terminals for bench test
► Signal Source Validation
Check display input mode: Disconnect green control wire to force CVBS mode
Cycle power after signal switching (AHD↔CVBS transition requires reboot)
► Legacy System Check
Test CVBS compatibility: Connect to TV’s RCA input (NTSC standard verification)

Q2: Monochrome Display Issue
Observed Behavior:
Loss of color rendering
Grayscale imaging
Diagnostic Procedure:
► Signal Standard Alignment
PAL/NTSC mismatch resolution:
AHD 1080P cameras: Set to PAL (50Hz)
CVBS analog cameras: Configure NTSC (60Hz)
