Camera traps are electrical instruments that emit sounds and light. In recent decades they have become a tool of choice in wildlife research and monitoring. The variability between camera trap models and the methods used are considerable, and little is known about how animals respond to camera trap emissions. It has been reported that some animals show a response to camera traps, and in research this is often undesirable so it is important to understand why the animals are disturbed. We conducted laboratory based investigations to test the audio and infrared optical outputs of 12 camera trap models. Camera traps were measured for audio outputs in an anechoic chamber; we also measured ultrasonic (n = 5) and infrared illumination outputs (n = 7) of a subset of the camera trap models. We then compared the perceptive hearing range (n = 21) and assessed the vision ranges (n = 3) of mammals species (where data existed) to determine if animals can see and hear camera traps. We report that camera traps produce sounds that are well within the perceptive range of most mammals' hearing and produce illumination that can be seen by many species.
相机陷阱是发出声音和光线的电子仪器。近几十年来，它们已成为野生动物研究和监测中的首选工具。相机陷阱模型与所使用方法之间的差异相当大，而且对于动物如何回应相机陷阱的排放知之甚少。据报道，一些动物会对相机陷阱产生反应，而在研究中这通常是不理想的，因此了解动物受到干扰的原因很重要。我们进行了基于实验室的调查，以测试12种相机陷阱模型的音频和红外光输出。在消声室中测量相机陷阱的音频输出；我们还测量了一部分相机陷阱模型的超声波（n = 5）和红外照明输出（n = 7）。然后，我们比较了哺乳动物物种（有数据的情况下）的感知听力范围（n = 21）并评估了视觉范围（n = 3），以确定动物是否能看到和听到相机陷阱。我们报告称，相机陷阱发出的声音大多在大多数哺乳动物的感知听力范围内，并且产生的照明许多物种都能看到。
