Night vision
The baby unit has infrared LEDs that allow you to see your baby at night or in a dark room. When the baby unit detects low light levels, the infrared LEDs turn on automatically. The images from the baby unit are in black and white, and appears on screen.
NOTES
- It is normal if you see a short white glare on your parent unit screen as the baby unit is adapting to the dark environment.
- When the infrared LEDs are on, the images are in black and white. This is normal.
TIP - Depending on the surroundings and other interfering factors, like lightings, objects, colors and backgrounds, the display resolution may vary. Adjust the baby unit’s angle, or place the baby unit at a higher level to prevent glare and blurry display
