Many portable hidden cameras come with night vision capabilities. This feature allows the camera to record in low-light or no-light environments, making it an ideal choice for surveillance purposes in any environment. Some portable hidden cameras use infrared technology to capture clear images even in complete darkness. However, it’s important to note that the effectiveness of night vision can vary between different models and brands of portable hidden cameras, so it’s important to choose one with a reliable and high-quality night vision feature.
