Introduction

Researches say that taking a photo and enjoying the moment are not two separate things. Several of you have certainly been observing your animal friends running around at night and thought to yourself this would make a great picture.

However, you did not want to miss the moment by taking your phone out of your pocket and scaring the animals off. Lucky for you, that digital night vision device in your hand will enable you to snap that shot in a blink of an eye. This way, you can savor the moment and share it with others at the same time.

Digital Night Devices

This can be done both with digital night vision devices, as well as thermal devices. However, these two types of products are still somewhat different. Night vision devices, for example, feature the infrared illuminator and reveal the body of the entire animal. The detection range is around 400 m, but this can be improved by buying a separate illuminator.

 

 

Nevertheless, even the most effective of illuminators on DNV devices cannot compete against the range of detection of thermal devices. However, the performance of digital night vision devices with a separate infrared illuminator can encounter problems in difficult weather conditions and when meeting other physical obstacles.

Thermal Devices

Thermal devices do not need an infrared illuminator, as they are passive and operate without the need for light emission. When it comes to thermal devices, the user is able to see only the warm body parts of the animal. The range of detection for the most basic, entry-level thermal devices is 1 kilometer. When it comes to high-quality thermal devices, this range can reach up to 2 kilometers or longer.

Because thermal devices do not need an infrared illuminator, this also decreases the chances of scaring the animal off. What is more, weather situations and any physical barriers do not pose a problem when using thermal devices. The observer is capable of observing even in the rain, fog, and even past trees due to the color contrast it creates.

These multi-media capabilities have been available on many devices for several years now. In the past, an external recording unit was needed, meaning another device to connect to was required, which featured said capabilities. With the introduction of image capturing and video recording, we entered a whole new world, as these two features added value and changed the use of the devices.

Still, these capabilities are less common on cheaper devices. But in the last couple of years, we have been noticing the increase of less expensive devices also being able to capture images and record videos. In the NVD market, this can be seen on PARD NV007 and PARD NV019, for example, and in the thermal market, on Hikvision Lynx 6.

The devices with such multi-media capabilities most of the time also feature Wi-Fi connectivity, which means you can connect the device to your smartphone, to an application that allows the user to look back at images and videos and savor the moments, as well as stream live images. In the future, we expect most devices to take the pressure of capturing a moment off.

Conclusion

As mentioned, thermal and digital night vision devices are different mostly because of the technology used for their function. Both are intended for low light or night vision observations, as well as hunting. With some tech-savvy knowledge or with a help of a friend, you can get great pictures and videos of these furry creatures by using a digital night vision device, or a thermal device.
