Thermal cameras are important to people who spend most of their time on the water. They provide superior protection in challenging conditions especially in low light scenarios. Flir thermal cameras counter limitations making your trips on the water safer.
But what other benefits do marine FLIR thermal cameras offer? Are they better than radar technology and what are the best applications on the market? These are the topics we’ll be covering in this Flir marine camera review.
Both thermal cameras and radar technology have their advantages, limitations & purpose. The best option depends on what you’ll use it for. Let’s go through the features of both of these innovative designs.
Radar technology detects and displays echoes produced by an object whether it’s land items, rocks, floating debris or boats.
As mentioned before thermal cameras detect heat radiation from objects. But it also detects slight differences in heat as little as 0.01°C and displays them as different colors.
Typically radar applications can reach distances of 24 to 64 miles and further depending on the model.
Flir thermal cameras have a shorter range of approximately a quarter mile. Some models have a zoom function that allows the user to zoom in on objects as far as three miles or more.
Radar technology has the ability to display a 360° picture of all objects situated around the outside of your boat.
Unlike radar, thermal is designed to focus its view in a single direction of interest. When you point the camera in a specific direction it will only use thermal imaging in that specific point of interest.
There are many differences between radar technology and thermal imaging. But combined they will enhance your safety when you’re on your boat. Take a look at these differences between radar and thermal imaging.
