Does monitoring involve radiation, and is it harmful to infants?

Security cameras emit no radiation and do not generate electromagnetic waves; they merely capture reflected light from objects—i.e., sunlight or artificial light reflected off objects and entering the camera lens to form images. Therefore, positioning a camera to face an infant’s head poses no health risk. Details are as follows:

Under normal circumstances, people are not exposed to high-dose radiation in daily life, so associated health risks are minimal. The negligible radiation emitted by surveillance cameras falls well within the human body’s tolerance threshold. Simply having a camera installed does not inherently harm infants, and thus excessive concern is generally unwarranted.

Nonetheless, it is advisable to keep infants at a safe distance from cameras. Prolonged exposure to infrared (IR) light may cause localized temperature elevation, potentially leading to infant irritability and restlessness. Therefore, infants should spend minimal time within the field of view of IR-enabled cameras, and installing such cameras inside infant rooms is best avoided altogether.

This recommendation stems primarily from the fact that IR cameras rely on dedicated infrared light sources for imaging. Extended IR exposure can produce subtle thermal sensations, possibly causing discomfort or unease in infants. Consequently, minimizing time spent within the IR camera’s coverage area is strongly advised. In fact, IR cameras are designed for specialized applications and are not recommended for installation in rooms occupied by infants.

If you are concerned about potential radiation effects on your baby, consider incorporating moderate amounts of black sesame seeds into their diet. In Traditional Chinese Medicine (TCM), black-colored foods nourish the kidneys; the kidneys govern bone health, marrow production, and brain function. Since radiation exposure primarily affects the brain and bone marrow—thereby compromising immune function—consuming kidney-nourishing foods may help enhance cellular and humoral immunity, thereby supporting overall health protection.
