Infrared shooting error solution and analysis of causes
Infrared emission is the main front-end product for perimeter protection and is now widely used in the perimeter of factories, communities, airports, villas and other places. Due to a variety of reasons, the occurrence of false alarms due to infrared radiation has frequently occurred, which has caused great turmoil for users. The following is the analysis of infrared false-reporting solutions and causes, so that we can more reasonable purchase , installation, use of infrared radiation, reduce the possibility of infrared misfire.
Infrared shooting errors are mainly caused by the following three reasons:
1, the quality of the product itself. At present, the mainstream infrared emission brands in the domestic market are: Shenzhen Ai Lifu, Japan Ai Lifu, Fucos, Bosch, St. Wells and other brands, there are some underground factory production "Ai Lifu", product quality is not the same The quality is not the same. It is very necessary to choose a relatively high-infrared shot. It is recommended that you do not blindly map the cheaper, often the last but not worth the candle. Of course, there is no problem in the quality of high-end products. There will be inferior products in electronic products, and there will be problems in quality. However, high-end products and after-sales services are all done in place. In case there are problems, users also have problems. The corresponding service can be obtained, and the product can be used with confidence and peace of mind.
2, product design, installation problems. Anti-theft alarm system is a relatively complex system with high professional knowledge and technical requirements. Infrared emission installation requirements:
1>Pillar-type installation: It is required that the infrared radiation must be firm and firm after being installed, and it should not be displaced or shaken, so as to facilitate installation and defense and reduce false alarms. Otherwise, the wind will blow, resulting in inaccurate light problems. The details are described below.
2> Wall-mounting: Infrared radiation can provide 180° omni-directional angle of rotation, and pitch angle of 20° or more. Therefore, infrared radiation can be directly installed on the external walls or walls or fences of buildings.
3>Infrared radiation detector engineering debugging:
1 After the installation of the radio is complete, rely on the sensation to align the emitter with the receiver. After confirming that the wiring is correct, inject the infrared pair 2 and watch the indicator on the receiver. For example), if the red light (ie, the alarm light) is off, and the green light (level light) lights up as shown in the figure:
If the measured voltage reaches more than 1.4v, the infrared radiation can be covered and the commissioning can be completed. Otherwise you need to go to step 3.
3 Adjust the horizontal angle, and pay attention to the voltage reading of the multimeter at the same time, adjust it to the left and right, and stop at the highest value. Then adjust the vertical angle and adjust it up and down to get the highest value. Be careful not to block the light, either horizontal or vertical. If such adjustment cannot reach more than 1.4v, then step 4 needs another person to go to the emitter side to perform the same operation as the third step. The person at the end of the receiver stares at the multimeter, and if the voltage is up to the standard, he will shout at the end of the projector. Stop (if distance test requires pairings, etc.)
5 Summary: The above method of adjusting infrared radiation is faster and more precise than the method described in the manual.
3, on-site environmental factors. The outstanding reason is that the environment between the transmitting end and the receiving end has changed.
In summer, branches and wisteria are prosperous, and the principle of infrared radiation is that the infrared rays at the transmitting end are blocked, causing the receiving end to receive no infrared rays, and the receiving relay will immediately act. It is advisable to communicate with the property, pruning branches or wisteria. In the past, customers also encountered cases of false positives due to infrared rays caused by the company’s celebrations and the fluttering red flags on the wall.
It is hoped that the engineering company will take into account changes in environmental factors when resolving false positives.

For example), if the red light (ie, the alarm light) is off, and the green light (level light) lights up as shown in the figure:
Then connect the multimeter to measure the voltage in two small holes in the upper right corner of the infrared, as shown in the figure
If the measured voltage reaches more than 1.4v, the infrared radiation can be covered and the commissioning can be completed. Otherwise you need to go to step 3.
3 Adjust the horizontal angle, and pay attention to the voltage reading of the multimeter at the same time, adjust it to the left and right, and stop at the highest value.
