How do Trail Cameras Work?

Trail cameras are a perfect way to film or photograph wildlife on a hiking trip and there has never been a wider range to choose from, with many new models on the market now. Such common recreational technology pieces have a range of users, from wildlife photography to the theft detection.

There are several distinctive factors which distinguish the many trail cameras on the market. These features will serve as the criterion when searching for a trail camera, often called game cameras, to help you select the right camera for yourself. Many units have a motion detection feature that activates the aperture of the lens, and to complete this role every unit has a fixed detection area. Another important aspect for a good quality camera is image resolution and sharpness, as well as pixel count. Last but not least, a great trail camera needs to be able to focus the lens.

What should you consider?

When looking for a trail camera there are several factors to consider which will vary depending on the intended use:

Detection circuit – What movement does the camera detect? Which is the spectrum and field of view for detection?

Battery – How long does the battery last?

Infrared emitters – Does the camera have an undetectable ‘no light’ option or does it have an infrared flash with red glow?

Picture quality – Review the sample images to ensure that the standard is appropriate to your needs.

Set-up and viewing screen – Is the camera easy to set up? Does it have an internal viewing screen?

Trail cameras can be used for multiple applications and come in different styles, depending on your needs. Manufactures provide several features to explore, with many of the variations based on data storage and retrieval. For some, the conventional method of manually uploading images works just fine, while others prefer instant retrieval. The following list details the various types of trail cameras and their primary uses.


Digital trail cameras operate in the same way as conventional digital cameras – they are self-contained devices with night vision (based on infrarot, LED or traditional flash), power, and data storage capabilities. Such kinds of cameras operate by capturing a still frame the moment the detection feature is activated by an object or human, the parameters of which are decided by each maker.


Cellular units operate by digitally capturing an image, and then transmitting it to the cell phone of the user. This works by using wireless signals to allow the picture to be immediately retrieved. To use them, cellular trail cameras require a data packet, as well as a SIM card and a good signal at the location it is used.

Wireless Activated

Wireless enabled trail camera, which transmits the image through a wireless network, is another great choice for theft detection purposes. The unit may be connected to any receiving network or computer but it needs to be linked explicitly to allow the images to be transmitted and received. As with cellular cameras, wireless activated cameras allow the signal available to operate, and they do not work effectively in wilderness areas.


In low light or total darkness, many trail cameras are used, and many users use an infrared feature in these circumstances. Such cameras work through a sensor that is triggered when assistance is required-a light is emitted once a picture is taken to provide the exposure light. Infrared light offers more protection than standard white flash, but depending on the device, the infrarot light can be either red or white. This device’s pictures have a black, white or red tint to them.

Sound Producing

Many people who use trail cameras do so to capture wildlife, either for science or for recreation, and they want animals to get to the camera. Cameras generating sound work by storing recordings of animal noises or calls which can be picked for playback later. Depending on the chosen sound, the noise will either attract animals or scare them off. Such cameras digitally store the sound and pictures. Some versions are triggered by a motion sensor or timer and others can be disabled remotely.

Security Cameras

Trail cameras are also used for safety reasons, whether it is for athletes who use them to secure particular hunting spots or for people to track remote cabins. Such cameras are either locally or wirelessly connected to a computer network, and data is stored using a USB unit. These data may also be forwarded to another location depending on the operating system. There are some ethical problems with using such devices but they usually refer to bathrooms, dressing rooms or other private spaces.
