Not necessarily. High pixel density can actually reduce low-light sensitivity. For license plate tasks, 4MP or 5MP sensors often outperform 4K. They provide a better balance for high-speed shutter performance and night legibility without the excessive digital noise found in some 4K sensors.

Actually, standard Infrared (IR) is the gold standard for LPR for two reasons:
1. Driver Safety & Stealth: ALPR systems typically use IR lighting to capture clear images at night without blinding drivers or drawing unwanted attention to the camera's location.
2. Shutter Speed: IR mode allows the camera to operate with a much lower (faster) shutter time compared to color mode. This is vital to freeze the motion of a moving vehicle.
Furthermore, "Smart Dual-Light" cameras often have a delay when switching between white light and IR, which can cause you to miss the plate entirely during the transition.

LPR requires absolute data stability. A PoE (Power over Ethernet) cable connection is the "truth" to prevent data packet loss and ensure every recognition event is recorded.

You need to see the "characters," not the whole street. Optical Zoom allows you to physically narrow the field of view to the lane, maximizing the pixels on the plate itself. High FPS (Frames Per Second) ensures that even a speeding car provides multiple "chances" for a clear capture.

1.IP67 Weatherproof: Essential for any outdoor installation to withstand heavy rain and dust.
2.Full-Metal Housing & IK10: For street-side or warehouse use, you need protection against vandalism to secure critical evidence.
3.Long-Distance Night Vision: Look for high-intensity IR LEDs that can reach the required recognition distance clearly.
