Is there radiation from monitors, and does it affect infants?

Under normal circumstances, surveillance cameras themselves do not emit radiation or electromagnetic waves; they primarily capture reflected light from objects to form images. Therefore, monitoring devices have no adverse effect on infants. The detailed analysis is as follows:

Modern surveillance cameras and baby monitors use wireless technologies such as Wi-Fi or Bluetooth. The electromagnetic radiation emitted by these devices falls into the category of non-ionizing radiation, similar to household appliances like mobile phones and microwave ovens. Non-ionizing radiation does not carry enough energy to damage DNA or cellular structures, so its impact on the human body is considered extremely minimal within normal usage levels—especially for intermittently used monitoring equipment. Some surveillance cameras may employ infrared technology to operate in low-light or nighttime conditions.

Infrared cameras emit infrared light, but this type of light does not belong to harmful radiation categories; it is merely used to assist imaging. If an infant is exposed to infrared light from a camera for prolonged periods, they might feel slight warmth or discomfort, potentially leading to irritability. However, this is not due to radiation damage, but rather a physiological response caused by minor temperature changes.

Surveillance cameras themselves are not radioactive and do not pose a direct radiation threat to infants. Nevertheless, prolonged exposure to infrared light or the mere presence of a camera in an infant's room may have some indirect effects. Therefore, when using surveillance cameras, it is important to carefully position them and limit their operating time to minimize any potential impact on the infant. Parents should also pay attention to their baby's reactions and emotional changes, making timely adjustments as needed.
