How far can infrared cameras have night vision?

This problem is very general, just like you can see someone 100 meters away, and 10 meters you can see whether it is a man or a woman, the key is the effect you want to see, the current limit of ordinary infrared cameras is 150 meters, and then increase the lamp, and add more infrared lights, it is not possible, determined by the infrared wavelength. Also, don't understand what you mean by back-end irradiation. Array infrared technology is leading, the conversion efficiency has been improved a lot, and the night vision distance may be a little farther, about 200 meters or so, and there is also a laser, which is farther.

Summary. Depends on how many millimeters the camera is in the lens:

4mm 10 meters.

6mm 15 meters.

8mm 25 meters.

12mm 35 meters.

16mm 40 meters.

The infrared detector depends on the power of the infrared emitter. Secondly, it depends on the sensitivity of the sensor.

Generally, it is equipped with night vision devices, and the observation distance can reach 300 500 meters.

How far can the infrared camera see at night.

Depending on how many millimeters the camera is the lens: 4mm 10m 6mm 15m 8mm 25m 12mm 35m 16mm 40m IR detector depends on the power of the IR emitter. Secondly, it depends on the sensitivity of the sensor.

Generally, if you have a night vision device, the observation distance can reach 300 500 meters.

If my answer is helpful to you, please give a thumbs up (comment in the lower left corner), look forward to your like, your efforts are very important to me, and your support is also the driving force for my progress.

Night vision cameras can generally see a distance of about 50 meters to 100 meters at night.

If you judge by the clarity at night, then the black light camera that can still display in full color in low-light environments will undoubtedly win the championship. However, security cameras are not still photo contests, and black-light cameras can produce drastic blur when capturing high-speed moving objects.

Therefore, the field of view distance, camera width, dynamic tracking, and intelligent algorithm adaptability of the night camera are all factors that need to be considered. Generally speaking, home cameras have a small detection space, more obstacles, and slightly different lighting depending on the home environment.

Surveillance cameras can illuminate meters, etc., and there will be some gaps in the visual distance between day and night, and it may be broken a little at night. Cameras generally have, the angle is inversely proportional to the distance, the larger the angle, the closer the distance.

The millimeter lens is the degree, the distance is 15 meters, the 6 mm lens is the degree, the distance is 20 meters; The 8mm lens is the degree, and the distance is 25 meters, and the 12mm lens is the degree, and the distance is 40 meters; The 16mm lens is degrees, and the distance is 60 meters.

IR Surveillance Camera Features:

1. Sensitive to temperature, according to the temperature to form an image, can quantitatively identify the temperature data, and the temperature alarm limit can be customized by the user. There is not only the infrared temperature image display of the forest, but also the simultaneous display of temperature data, and the output of abnormal temperature alarm signal.

2. Trigger the alarm when alarming, and generate an alarm trigger signal to the background equipment through RS232 485 port.

3. It can completely penetrate the smoke and partially attenuate the dense fog.

4. There is no need for visible light, and the image clarity at night is even better than that during the day.

5. Fast response speed, 50Hz image output per second.

There are a lot of nonsense that I don't understand, and the eyes of people at 50 or 100 meters can't see clearly during the day, let alone the camera?

See if there is a type of light and camera, generally about 10-20 meters in total darkness, and about 20-30 meters in the case of light assistance.

Also, if you use high-end ones such as automatic zoom or license plates, those are a little farther away, like the general ones, such as rental houses, are 5---10 meters of night vision distance!!

The quality is generally within 60m, and the good point is more than 100m.

I think I can shoot it up to 100 meters away.

How far can night vision goggles see? This question is actually a bit envious and vague, and not too specific. What exactly is the "seeing" in the question, and what kind of effect is expected to be achieved?

In addition, what kind of night vision devices are used? After these two questions are defined, there should be a more accurate answer. Bumper Greeting.

Let's first talk about the "look" in "how far to see". To explain this question in great detail, we will divide "look" into four levels.

Four levels of night vision** targets.

The first level is "discovery", which means that you have a rough idea of the shape of the target, and can only judge whether the target exists from the screen;

The second level is "identification", which means that the target is found in a more detailed manner and can identify the target, such as whether it is a person or a vehicle, a cannon or an airplane;

The third level is "confirmation", which can distinguish the target in more detail, and can indicate the type of target it belongs to from the same type of target, such as whether the vehicle is a truck or a bus, and whether the house is a house or a factory;

The fourth level is "description", which can know the specific shape of the target in more detail, and identify the characteristics and details of the target. For example, it can point out the type of aircraft and automobiles and the equipment on the ship, and clearly distinguish between the main objects and accessories.

Of the four levels, Discover requires the lowest image resolution and the highest tolerance for image noise, while Description requires the highest image resolution and minimal image noise.

When we use night vision targets, we first need to be clear about which of the above scenarios we expect to achieve. Only after a clear description of your own effect can you find a more suitable night vision device product.

The probe can see as far as it can during the day and as far as it can see at night, but the image is not as clear at night because of the darkness.

No. The monitoring night vision function also means that there is infrared. The red dots of light are just an infrared mode of surveillance cameras, called infrared lights.

When the hail in Muzhen arrives at night, you can see a little red dot when you turn on the infrared. There are other IR modes that do not see the IR lamp, such as the camera that uses the filter to switch the IR working mode.

Monitoring composition. 1. General monitoring system.

The composition mainly includes the front-end part of the control department: camera, lens, infrared lamp, PTZ, intelligent dome camera, bracket, etc. Transmission Section:

2. Remote expansion system.

Monitoring does not simply refer to the closed-circuit television Xunfan monitoring system, but the monitoring system in the traditional sense is composed of front-end cameras (including: dome cameras, infrared cameras, all-in-one machines, etc.) plus mid-end equipment (optical transceivers, network servers, etc.) and back-end equipment hosts (hard disk recorders, IP-san, matrix, etc.).
