"Forensic night vision device", as the name suggests, is also known as "photography night vision device" or "digital night vision device". There are two biggest features of this type of forensic night vision device. One is that it can be used all day and night, and the other is that it can take photos and videos for evidence collection. Let's introduce the classification and main features of forensic night vision devices.

Regarding the classification of forensic night vision devices, there are two ways. The first way is to classify according to the clarity level of the forensic instruments, which correspond to the forensic night vision instruments of the 1-4th generation. At present, the ultra-high-definition forensic night vision instrument is the 4th generation of forensic night vision instruments. The second method is divided into monocular and monocular forensic night vision device (Figure 1) and binocular binocular forensic night vision device (Figure 2) according to the appearance and viewing method of the product. At present, the binocular binocular forensic night vision device will be more popular, because the binocular is more comfortable for long-term viewing and use, and the binocular hand-held feeling is like using a telescope, which is more in line with the usage habits of most people.

The characteristics of the forensic night vision device need to be introduced in detail here. The following is an example of the latest 4th generation forensic night vision device.

Feature 1: All-weather day and night use

The 4th generation forensic night vision device supports day and night dual-use all-weather observation, completely independent of time and ambient light. When you can choose the color viewing mode in daytime or low light environment, the picture is more realistic. When you are in a dark or dark environment at night, you can choose the viewing mode in black and white, and turn on the infrared auxiliary light of the forensic night vision device. At this time, the viewing effect is better, and it is not easy to be detected by the target.

Feature 2: Zoom function for zooming in and out of images

The smooth digital magnification zoom (5-30 times change) of the 4th generation forensic night vision device realizes the perfect combination of magnification and field of view. The viewing target can be zoomed in or out to see the panorama and details up close. Let you appreciate the beautiful scenery of "looking across the ridge and forming the peaks, the distance is different from the distance". If you are watching a person, you can see the details of the face very clearly even at a distance of 200 meters.

Feature 3: Ultra HD photo and video forensics

The 4th generation forensic night vision device has ultra-high-definition photo and video forensics functions, and can be turned on with one key. That is, while we are watching the target, we can press a button on the instrument button to realize the function of taking pictures or video, and record and save the wonderful moments you see in time. It can also record the sound around the instrument and save the date on picture and video files.

Feature 4: 2000 meters ultra-long visual distance

In the outdoor low-light environment, the 4th generation forensic night vision device can organically combine the magnification of 5-30 times with the 1080P high-definition image quality, and can reach an ultra-long viewing distance of 2000 meters.

Feature 5: WIFI connection to mobile phone to achieve synchronous viewing and remote control functions

The 4th generation forensic night vision device can be connected to smart devices such as mobile phones (Android and iOS systems) through the built-in Wi-Fi of the instrument. Users need to download a corresponding APP on smart devices such as mobile phones. Through the APP software on the mobile phone, you can view the images displayed in the eyepiece of the instrument in real time synchronously, remotely control functions such as taking pictures and recordings, remotely set parameters, and operate playback/download/delete/one-key sharing of pictures and video files, etc. . It is equivalent to fixing the 4th generation forensic night vision device on a tripod and aiming at the observation target. We can see the scene of the forensic device through the mobile phone, and we can also remotely control the parameter settings on the forensic device without going through the menu of the instrument. At this time, the mobile phone is equivalent to a monitoring screen and a remote control. As long as the mobile phone is within 20 meters of the instrument.

Feature 6: Multiple power supply modes, long standby time

The 4th generation forensic night vision device supports a variety of power supply methods, such as rechargeable batteries, mobile power (charging treasure), DC power, vehicle power supply, etc., to meet different choices and flexible use. For example, if you use a 20,000mAh power bank, it can last for 3-5 days.

Other features

There are many features of the 4th generation forensic night vision device, such as HDMI high-definition video output, integrated display, GPS positioning, image brightness adjustment and so on.

Regarding the applicable groups of forensic night vision devices, I think there are two. One is the observation and recording of the living habits of wild animals by the wildlife action expert group, and the other is the forensic work of the criminal investigation, public security and other departments. What do you think about the other uses of the 4th generation forensic night vision device?
