Solution

Starlight-level CMOS image sensors (e.g., Sony IMX415, 8MP, 0.001lux) deliver clear color imaging in near-dark conditions, eliminating the need for IR LEDs.

High-dynamic-range (HDR) ISP chips (e.g., ADI ADV7842) suppress glare/overexposure in harsh lighting (e.g., backlit entrances), maintaining detail in both bright and shadowed areas.
