This product is the SpyFinder hidden camera detector/locator. It is extremely reliable and simple to operate, and will alert you to any hidden cameras it picks up on. It is the most user-friendly product of its kind on the market, and it is able to detect hidden cameras though optical augmentation. This essentially means that any hidden cameras will be detectable based on illuminating the surrounding area with the unit’s ring of ultra-bright LED lights (surrounding a viewing port). If there is a hidden camera in view of the SpyFinder, it will be given away by a strong reflection of the LED lights.
