day-night-hunt

 

Day hunt

Unlike classical night vision devices based on electron-optical converters, digital devices operate on the principle of a video camera, and their sensing element (sensor) is not afraid of flare. Thanks to this, digital night vision devices (day / night devices) can be used during daytime hunting.

The resulting image in these devices is displayed on the built-in display, and the absence of a special filter that cuts off the waves of the IR spectrum (in view of the need to use an IR illuminator for work at night) may affect the accuracy of color reproduction in the daytime, which is not a critical aspect and does not affect the daytime hunting process.

 

Night hunt

Hunting in dawn-twilight and at night is one of the most popular areas of application for observation and sighting digital devices.

Digital monoculars and rifle scopes are most often used for hunting. Binoculars are less commonly used if observation is carried out from a tower and it is possible to mount the device on a tripod.

The digital rifle scope for night hunting can be used as the main tool for finding and hitting a target.

A popular solution is also a tandem of a thermal imaging monocular and a digital rifle scope.

Digital devices have a lower sensitivity than electronic-optical converters, therefore, for their successful use at night hunting, an IR illuminator is important.

 

 

security-special-operations

 

Security

For security purposes and patrolling, the most popular solution is the use of stationary digital night vision cameras.

These devices are designed for round-the-clock monitoring, as they are powered from the electricity.

They are equipped with infrared illumination for night operation. Digital surveillance cameras can be equipped with a wide variety of functions and sensors (motion tracking, target lock, automatic notifications, and more).

The resulting image is displayed on an external monitor.

Hand-held and tripod-mounted digital devices are also used for security and patrolling: monoculars, binoculars, and spotting scopes.

 

Special operations

There are increased requirements for devices that are designed to be used for special operations, which primarily means operating conditions, performance and stability.

The army most often uses expensive night vision devices based on electronic-optical converters and thermal imagers.

Digital surveillance devices are used to protect important objects (stationary cameras), when searching for missing people, catching  criminals, liquidating the consequences of emergencies (monoculars, rifle scopes, binoculars).

Regardless of the tasks, these devices must have a high resistance to external loads and adverse weather conditions.

 

 

tourism-sport

 

Tourism and surveillance

Digital day and night vision devices are very popular with tourism and nature observers.
