General infrared cameras are sealed and protected to IP66. However, when the infrared lamp starts to work, it will generate a lot of heat. At the same time, due to the insufficient heat dissipation effect of the outer shell and the poor sealing of the machine itself, the machine will appear more or less soda after a period of time (this phenomenon is mainly concentrated In the northern region), the monitoring effect is affected. Some manufacturers of this part adopt ventilating design, increase ventilation valve to facilitate exchange with external temperature, and some use nitrogen filling to ensure that the interior of the machine is inert gas to ensure that there is no water vapor.
II: The effect of night vision is not ideal
The main manifestation of this phenomenon is the effect of the flashlight or the distance is not enough. In fact, this problem is mainly caused by the infrared light's angle and function. The infrared light used by the infrared camera has a peak wavelength of 850, and the angle can be selected from 5-60 degrees. When the angle of the infrared transmission tube is smaller, the farther the illumination distance is, the flashlight's The more obvious the effect is, on the contrary, the greater the angle there is no flashlight effect, but the distance is greatly reduced. To solve this problem is mainly to see what kind of effect manufacturers want to pursue and what kind of cost, of course, the power and price of infrared light It is proportional and the distance can be reached. The far-seeing universal infrared camera products use the industry's first-class infrared lamps and lenses to ensure the night vision effect and completely eliminate the flashlight effect.
Three: IR integrated camera color cast during the day <br> <br> low-quality manufacturers of color cast during the day will be more or less, the most direct reason is the problem of camera filters generally use infrared integrated camera can penetrate A certain percentage of infrared light double-pass filter has the advantage of low cost, but because natural light contains more infrared components, when it enters the CCD, it will interfere with color reproduction, such as the green plant becomes gray and so on. The sunny outdoor environment is particularly noticeable). The use of the IR-CUT dual filter effectively solves this problem. The IRCUT dual filter consists of an infrared cut filter and a full-spectrum optical glass. When the daylight is sufficient, the IR cut filter operates. The CCD restores the true color. When the nighttime light is insufficient, the infrared cut filter automatically moves away, and the full-spectrum optical glass starts to work, making the CCD make full use of all the light, thereby greatly improving the infrared performance. The far-sighted IR-CUT adopts a mechanical design to ensure no color cast during the day and no coke at night. The infrared effect is well guaranteed.
Four: the critical point repeatedly jump <br> <br> This is because part of the matter is equipped with dual filter IRCUT still camera with filters ** In some complex light environment can not create stable jobs The same time, because most manufacturers are using a simple way such as photosensitive resistance sensors to control the IRCUT** filter working conditions, the critical point of repeated changes will not be satisfactory. This part of the complete solution is photosensitive sensor internal sensors, through the use of smart chips to control, its fuzzy logic capabilities can effectively control the IRCUT dual filter operating conditions.
Five: infrared lamp life of the most important factors that influence the heat dissipation problem <br> <br> temperature, due to the configuration of the heat a large infrared light, infrared light after starting, the entire work period (in 12-hour basis) in There will be heat concentration in the front of the infrared camera, which will affect the normal operation of the camera and other components. For example, 50 ¢5 infrared light board, the long-term operation, the LED board temperature can reach almost 90 degrees. Since the radiated power of the infrared-emitting LED is proportional to the current, many non-standard manufacturers increase the current by increasing the current, but the higher the current, the higher the temperature. Although the irradiation effect is improved, the machine itself will be greatly damaged due to overheating of the LED. Among them, the CCD behind the LED board is the most direct victim. The far-seeing Universal Infrared machine uses a constant-current power supply to apply the pulse width modulation law to keep the infrared lamp current constant, thereby reducing the infrared lamp's heat generation. No matter how the external input current fluctuates, the current entering the infrared lamp through the circuit They are all very stable, so as to ensure that the infrared lamp can exert its own maximum efficiency, extend its life, maintain a constant current, and control the heat dissipation of the LED. The LED lamp panel and housing are made of aluminum alloy and other materials with good heat dissipation to ensure that the long-term operating temperature of the infrared lamp is not increased. Above 50 degrees, life can reach more than 30,000 hours.
Mastergrip Laser Distance Meter
Product Description:
A laser distance measure is an advanced measuring tool to measure any distance without any efforts. It has a laser beam that is produced by the meter with the help of a battery and reflects it through a lens. The meter can measure the distance covered by the leaser and the result is shown on the display. Mastergrip laser distance meter is a digital distance measuring tool for precise and effortless measurement taking. It is an ideal measuring device for contractors, insurance adjusters, architects, flooring professionals and other people who do a lot of measuring. However, homeowners can easily use laser tape measures around the house, too.
User instruction:
Place the device on one end of what you want to measure, and then aim the laser beam so that it hits an object at the other end..If there's no wall, pole or anything like that, put a target at the spot you want to measure up to. The process is similar to using a conventional tape measure, except you use a laser beam instead of metal tape. Once you have the laser at the right spot, press the button, and the tape measure calculates the distance and displays it on its screen. The calculation is done through precision optics and laser physics using the phase-shift method, in which a laser hits an object and compares its reflection with the beam sent out, or using the time-of-flight method in which the time it takes for an optical pulse to reflect back is calculated. Some laser tape measures let you measure multiple distances and add them together automatically.
