IR LED Illumination and ICR Control Reference Design for IP Network Cameras With Day/Night Vision

TIDA-01586

Design files

Overview

This reference design showcases an Infrared LED illumination sub-system for Internet Protocol (IP) network cameras with day and night vision. The system features a cut filter control, LED dimming, ambient light measuring and ballasting for current of each IR LED string. Ballasting is an alternative for driving multi-string LED arrays with a single string LED driver while maintaining uniform illumination under low-light conditions. The OPT3001 Ambient Light Sensor (ALS) with precise visible light measuring and good IR rejection, is an ideal preferred replacement for photodiodes, photoresistors or other ambient light sensors.

Features
  • Incorporates current ballasting to equalize IR LED currents between strings in a multi-string LED array while using a single-string LED controller
  • Offers firmware-adjustable ambient light level thresholds and ambient light measurement modes
  • Offers PWM-adjustable illumination brightness levels
  • Offers ICR open or close control for day and night vision by using a simple motor driver
  • Incorporates the ability to operate from either a 12-V or 5-V power supply
  • Designed with headers compatible with BoosterPack™ plug-in module ecosystem with software designed to work with MSP430FR2311 MCU LaunchPad™
