How does a trail camera work typically?

A trail camera is a security device for detecting and surveying people, animals, and plants in outdoor environments.

Trail cameras are use primarily to find game when hunting or locate other phenomena out-of-doors off pavement – including remote areas with little foot traffic.

They may also be used by hunters to identify patterns of animal behavior prior to hunting them in the wild.

Primarily designed for wildlife study purposes, modern models can function in weather as low as -4 degrees Fahrenheit (°F) if they come equipped with adequate insulation around the power supply circuitry (i.e. battery).

How does a trail camera capture images and video?

A trail camera is a standard camera linked to motion detectors that detect movement in a certain radius of the camera.

It can either capture an image (in a series of photographs) or video depending on whether the device is configured to operate in snapshot mode or video mode.

If it is set up to function in snapshot mode, it will typically take ten photos per trigger before re-charging the batteries and continuing.

What Do Game Cameras Do?

Trail cameras, or game cameras, are incredibly helpful for monitoring areas where you hunt for game, such as deer.

These cameras have also become popular among wildlife photographers and homeowners looking for affordable home security.

Yet, before buying a trail camera, you likely want to know how one works. In this article, I’ll explain the basics of how game cameras work, why you should use one, and the main features that you can expect from a typical camera.

How Does a Trail Camera Work?

A trail camera is a camera housed in a rugged, waterproof shell. The camera is typically secured to a tree at a height of at least three feet.

The camera is often equipped with a motion sensor, heat sensor, infrared LEDs, and a memory card slot. Most cameras are battery-powered using AA batteries.

However, the camera remains in a deep sleep state during most of the day and night.

The motion sensor and heat sensor remain powered but draw very little electricity.

When the sensors detect animal movement, the camera wakes from its sleep state.

Depending on the settings, the camera snaps a series of photos or records a video clip, which are stored on a removable memory card.

Some cameras may include the time, date, and geographical location or send notifications to your phone.

Why Use a Trail Camera?

A trail camera is often used by hunters to scout hunting areas. The cameras allow you to monitor animals in greater detail.

For example, you may notice increased animal activity, indicating larger wildlife populations in the area.

You can also review the photos to assess the health of the animals, such as whether they appear malnourished or well fed.

You can also set up cameras to determine which trails receive the most traffic. Pay attention to which direction the animals come from and how frequently they pass by the trail. As the images are typically timestamped, you can look for patterns to figure out the best spot for hunting.

Monitoring animal behavior and travel patterns may also help you choose the right location for a deer stand.

Identify the areas of your property that receive the most traffic and position your stand accordingly.

Wildlife photographers may use the same cameras to narrow their search for the best photo opportunities.

Instead of spending the entire day in the field, you can focus on a specific area or time of the day.

How Does a Trail Camera Work – Important Features

Some of the main features of the typical trail camera include:

  • Motion sensor range
  • Night vision range
  • The angle of the lens
  • Video and image quality
  • Wireless connectivity
  • Geo-tagging
  • Battery life

The motion sensor range determines how close animals need to be to trigger the camera. Quality trail cameras, such as the Bushnell Trophy, have a range of 80 feet. The night vision range should match the motion sensor range.

The angle of the lens varies. If you want to cover a wider area, look for wide-angle lenses (120 degrees and up). You should also pay attention to the video and image quality. Game cameras often record 720p or 1080p HD video. The camera sensors range from 12 megapixels to 30 megapixels.

Wireless connectivity is included on some of the more expensive cameras, which are also called “cellular cameras” or “cellular trail cameras.” The wireless connection is typically used to send notifications to your smartphone. The notification may also include a preview of the image snapped by the camera.

Geo-tagging is useful for those who use multiple cameras. The geo-tagging feature adds the geographical location to the timestamp, along with the date and time.

Most trail cameras are powered with four to six AA batteries. The battery life varies significantly depending on whether you snap photos or shoot videos. A typical camera may last a year or longer before needing new batteries when taking photos. Recording video clips uses more power, resulting in an average battery life of just two to three months.


Trail cameras are remote cameras secured to trees or posts to scout and monitor animal activity. The cameras take photos or videos when a motion sensor detects movement.

Using a trail camera gives you a better sense of what is happening on your property or hunting trail when you’re away. You can review the photos and videos to determine what types of animals are in the area and where they were coming from.
