Using Two RealSense Cameras Facing the Same Scene: Depth Interference Concerns?
Hi, We are currently planning an indoor experiment (living room–like environment) where we would like to use two Intel RealSense cameras simultaneously.
Both cameras will be positioned with some flexibility in placement, but they will capture overlapping views of the same scene (i.e., partially observing the same area from different viewpoints).
Our main question is:
Will using two RealSense cameras simultaneously in such a setup negatively affect the depth output?
In particular, we are concerned about potential interference between the active depth sensing signals (e.g., IR emitters / laser patterns) from the two devices.
More specifically:
- Could the emitters from one camera interfere with the other and degrade depth accuracy or stability?
- Are there known best practices for multi-camera setups with overlapping fields of view?
- Are there recommended configurations (placement, angles, distance between devices) to minimise such effects?

Hi JINGJING LIU Multiple RealSense 400 Series cameras do not interfere with each other and overlapping their fields of view can actually improve depth analysis. This is because each camera projects a pattern of invisible IR dots that the camera uses to aid depth analysis of surfaces. When the dot pattern projections from two cameras overlap it increases the density of the pattern in the area where the views overlap, which is beneficial to depth analysis.
The RealSense models that could experience interference from multiple cameras were the SR300 and L515, which are retired and no longer available.
Although 400 Series cameras do not interfere with each other, they can interfere with non-RealSense IR devices nearby, such as card reader devices and wireless mice, or non-RealSense cameras that use IR.
