Trail cameras have become an essential technology in the current age. Not only hunters use them, but trail cameras are also used as theft detection. You can set up one in front of your house and monitor it from inside. But how does a trail camera work? You will be lying if you say you never asked this question. We are here today to answer that question of yours.

How Does a Trail Camera Work

Discerning Factors

Several factors distinguish the different kinds of trail cameras. These factors not only provides product diversity they also help provide criteria for customer selection. We listed some of these factors in this section. 

Although the discern different models of trail cameras from each other, these are the basic function that most of the cameras has. A lot of units have motion detection feature. The sensor activates the lens when it detects movement.

Image resolution and sharpness is another concerning matter. If the camera doesn’t provide photos with enough sharpness and clarity you are better off avoiding that. The ability to speed lens focus is just as important.

Digital Trail Camera

Digital trail cameras work as a digital camera. They are self-contained units. They also feature the night vision capability. The power up from batteries and can accept microSD memory cards as storage. 

When an animal/person enters the detection zone the lens auto clicks and captures the footage. Some of the digital cameras can also record up to a certain amount of video footage at respected resolution. A lot of units provide night vision through IR cameras, LED or traditional flash.

Cellular Trail Camera

They capture images just like digital trail camera but instead of saving them in a physical storage vault-like microSD they transfer those images directly to user’s cellphone. 

They do it by utilizing mobile data or Wi-Fi. If you purchase a cellular one keep in mind that they need a physical sim card just like your phone to access the internet. This means you need to purchase a separate data plan for your trail camera.

Laser Aim

Just like digital trail cameras, they work similarly. But the change here is the user can set up the laser to focus on a field. The camera going to take pictures of that selected field. Resulting in better quality images.

Strobe Flash

The main goal of a trail camera while hunting is stealth. The idea behind a strobe flash trail camera is when the prey enters the detection range the camera emits a small flash. The speed of flash is high, maintaining the user’s secrecy. 

Wireless Activated

This type of trail camera is ideal for home uses. Because you can pair it with your home wireless network then link it with any device you want. After that whenever the camera takes a picture it is going to send that picture to the linked device through the wireless network you connected to.

This type of camera is not good for wildlife/hunting. Because you can’t get any kind of wireless connectivity in the jungle. 


A lot of modern trail cameras feature some sort of infrared technology. Infrared works like a traditional flashlight but the difference is they are not bright like a regular flash. Instead, it emits a red color spectrum. They are secretive. It’s quite impossible to notice the red color spectrum from far. 

Infrared also makes sure you get a clear night vision. If your trail camera has any kind of IR that means it is a-ok to perform even in the darkest night. If you hunt at night or want to observe your backyard/front at night, then you must choose a trail camera which has infrared feature.

How Far Can a Trail Camera Take a Picture

The answer to this question lies within the model of the camera you choose. Your camera can have a range anywhere from 40 feet to 120+ feet. It will depend on the model you choose. The detection range of the camera also depends on the purchased model.

Make sure to read the specifications chart before purchasing. They always mention the range and detection range there.

Battery Life

Digital trail cameras need a power source to run. If you buy it for anti-theft purposes chances are you can wire it directly to your house circuitry. 

But in wildlife, there is no powerhouse their. That is why the trail cameras use the li-ion battery to power themselves.

The battery life will also depend on the unit you purchase. Some trail camera lasts for around 10-11 months. But if you keep it on for 24/7 then chances are they will run out within a month.

Final Thoughts

You can choose any trail camera you like. So that is how a trail camera works. While some features some fancy sensors the others doesn’t. The amount of money you are willing to spend will also play a key role behind the trail camera.
