Digital night vision camera is a device that combines digital technology with night vision function and can take photos in low light or dark environment. The following is a detailed introduction for you:

Features of digital night vision camera:

Clear imaging: Using advanced digital image sensors and image processing technology, it can provide relatively clear and delicate images, effectively improving the recognition of target objects.

With photo function: It can capture scenes or targets of interest at any time, convenient for recording and preserving evidence, moments, etc. The photos taken can be stored in the device's built-in memory or external memory card for subsequent viewing and sharing.

Video recording: Some products support video recording function, which can be used for long-term monitoring or recording dynamic scenes. It is very practical for some situations that require continuous observation, such as wildlife observation, security monitoring and other scenes.

Long observation distance: Some high-performance digital night vision cameras can reach hundreds of meters in a completely dark environment, meeting the use needs of a variety of outdoor and professional scenes.

Multiple function integration: Often integrated with functions such as GPS positioning, electronic compass, Wi-Fi transmission, etc., to provide more convenience and safety for outdoor adventures, field operations, etc.

Working principle：

Photoelectric conversion and electronic amplification: The image sensor in the device converts weak light signals or infrared light signals into electrical signals, and then amplifies and enhances the electrical signals through electronic amplification circuits. Finally, the amplified electrical signals are converted into visible image signals, presenting a clear image, allowing the observer to see the object in the dark.

Thermal imaging principle: Imaging is achieved by detecting the thermal radiation emitted by the object. In a completely dark environment, a clear image can be formed based on the temperature difference of the object. It is very effective for some scenes that need to be observed in extremely dark environments and are sensitive to temperature changes, such as night search and rescue, and heating fault detection in power equipment inspections.

Application scenarios：

Outdoor adventure: Help explorers observe terrain, find water sources, and discover potentially dangerous animals at night to ensure their own safety, while recording the wonderful moments of the adventure.

Wildlife observation: Researchers or wildlife enthusiasts can use it to observe the nighttime behavior habits and activity patterns of animals without disturbing them, obtain precious research data or take wonderful animal images.

Security monitoring: Installed in homes, communities, factories, public places and other areas, it effectively monitors the surrounding environment at night, prevents illegal and criminal acts such as theft and robbery, and provides evidence for the police to solve cases.

Law enforcement and military: The police can use digital night vision devices to find targets, collect intelligence, and record on-site conditions during night patrols, reconnaissance, and law enforcement operations, and the military can use digital night vision devices to find targets, collect intelligence, and record on-site conditions during night combat and reconnaissance missions.

Industrial detection: Used to check the operating status of industrial equipment at night, pipeline leakage detection, power line inspection, etc., record problem points by taking photos or videos, and facilitate subsequent repairs and maintenance.

Representative product examples:

1、Onick NP-1600 infrared night vision digital telescope adopts excellent optical, electronic and mechanical system integration design, with clear objective lens imaging, stable electronic functions and comfortable eyepiece imaging. It has both night vision and daytime telescopic functions, especially its low-light full-color night vision function, the first domestic thermal image pseudo-color display, outstanding performance, can be viewed at a distance while taking photos, recording videos, recording wonderful moments. NP-1600 is an intelligent digital binoculars that integrates image transmission, GPS + Beidou, electronic compass sensor, angle sensor, altitude pressure sensor and other multi-functions.

2、Onick NB550 is a 4th generation digital night vision device that can be used both day and night. It supports taking photos and 1920X1080 high-definition video recording. It supports a digital zoom range of 5x-30x, which can bring the viewing target closer or farther away. The GPS positioning and electronic compass functions of Onick NB550 are very suitable for outdoor use, ensuring that the user has a more accurate direction positioning. The night vision device and the mobile phone APP can be connected via WIFI to transfer images, or the corresponding buttons on the screen can be directly clicked on the mobile terminal supported by the APP to perform recording and photography functions. Pictures or image files can be played back on the night vision device, and the files can be deleted or protected. The USB port can be connected to a computer to read SD card files, and a 5V 1A mobile power supply can also be connected; the HDMI port can be connected to a separate display screen to watch or take photos and videos through the display screen.

3、Onick NB-800L 4G image transmission version multi-function handheld laser night vision device adds green laser rejection function, remote wireless button control function, pitch angle, roll angle, electronic compass azimuth and other functions on the original basis. It supports up to 512G ultra-large memory, which is more suitable for close-range day and night 24-hour evidence collection and recording. Supporting 4G wireless transmission, supporting APP remote real-time viewing, taking pictures and recording, the product is more practical, with clear imaging during the day and good image effect at night. This series of products has a high degree of integration, small size and light weight. It is specially developed to meet the convenience of users to carry and operate, so as to meet the needs of automatic evidence collection in various fields around the clock. It is a color image (or black and white image) during the day and a black and white image at night: the farthest monitoring distance during the day can reach two kilometers. It is an excellent high-tech night vision monitoring product with extremely high cost performance after actual application testing among similar products. The equipment has a long life, good stability, good effect and excellent quality.
