Titanium alloy is a class of metallic materials widely used in various high-performance applications. It is a combination of titanium with other elements, such as aluminum, nickel, molybdenum, and vanadium, to enhance the properties of pure titanium.
One of the key advantages of titanium alloys is their high strength-to-weight ratio. They are significantly lighter than steel while being just as strong, making them ideal for aircraft, missiles, and spacecraft. Moreover, titanium alloys possess excellent corrosion resistance, which makes them highly suitable for marine, offshore, and chemical processing environments.
In addition, titanium alloys exhibit good biocompatibility, which makes them suitable for medical implants such as artificial joints, dental implants, and pacemaker cases. They also have high fatigue resistance, low thermal expansion coefficient, and excellent weldability.
Overall, titanium alloys have become an essential material in many industries, including aerospace, marine and offshore engineering, chemical processing, biomedical engineering, and sports equipment. As research continues to advance, it is expected that more innovations in the field of titanium alloys will arise, paving the way for even safer and more efficient applications.

The first is to extend the use time of IR waterproof camera IR lamps and affect the service life of the products.
The second is to turn on the infrared light for situations in which color images can still be produced, which will cause the image quality to drop at this time;
The third is the generation of infrared eye on the color image (infrared eye is also determined by the principle, people do not want to see the phenomenon). If the threshold is low, the infrared light may not turn on in time when additional lighting is needed.
Current ordinary infrared waterproof cameras generally use photosensitive elements to detect the illumination intensity of the environment in which they are located. According to the threshold determined in the design parameters, control signals are generated to enable the opening of the infrared lamps. The level of the threshold depends on the environment used, the preferences of the users, and the degree of importance of the designer considering various factors. The products of the manufacturers are different. Such as 20,10,5 Lux. When the threshold is high, the opening time is earlier. It is possible that the camera has not yet converted from color to black and white, and the infrared lamp is turned on. This will have three disadvantages.
So how to solve this problem?
The ambient illumination detected by the photosensitive element is slightly lower than the threshold, which is a problem. There are two situations:
one. At some point in the evening, for a short period of time, this problem arises. If we do not want to increase the cost, we should adopt a general mindset. Our idea is to explain the reason to the user and tolerate it.
two. This issue must be resolved when the lighting intensity is stable.
1. Change the threshold.
In the same model, the thresholds are also different and there is a discrepancy. The problem may be solved by replacing a product.
Manufacturers provide products with different design thresholds for replacement.
Products with higher threshold design parameters are less likely to flicker.
2. Change the environment Change the intensity and angle of the lighting.
A slight change in the installation angle of the infrared waterproof camera, moving up and down, the illuminance detected by the detector will have a lot of changes, it will leave the vicinity of the threshold, so as to solve the problem of flicker.
3. High-quality, low-illumination camera domes with backlight compensation and anti-glare, especially dedicated IR lenses;
In addition, when a person or other object near the infrared waterproof camera reflects infrared light, the detected illuminance changes repeatedly, causing flicker. For example, when doing demo tests, inspections, and the installation position of the camera is low, when an object covers the camera at close range.
This is not a problem. When the IR waterproof camera is in the normal installation position, this phenomenon is naturally gone. As a demonstration, just pay attention not to direct infrared light from a close distance to the photosensitive element.
Why is the infrared waterproof camera flashing? As mentioned before, the infrared lamp turns on when the illumination intensity is lower than the threshold. Closes above the threshold. Let us consider the situation when the illumination intensity is slightly lower than the threshold value: the photosensitive element detects that the illumination intensity is slightly lower than the threshold value, and controls the infrared lamp to turn on and emit light. After the infrared lamp emits light, the detected illumination increases (plus the anti- The returned infrared light exceeds the threshold and controls the infrared lamp to turn off - resulting in a decrease in the detected illumination, and once again controlling the infrared lamp to turn on. This does not stop, causing the image to flicker. This kind of situation is the principle reason, not to say it is normal, at least not the quality of the product.
