Infrared shooting errors are mainly caused by the following three reasons:
1, the quality of the product itself. 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 feeling 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:
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. 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.

Hydraulic Rising Road blockers General Description Road blockers are designed especially for entrance points which have a threat of vehicle attack or for the ones that have high security requirements. If there is a threat of vehicle attack in addition to the control of vehicle access in high security applications, hydraulic road blockers are the unique solution and the most secure systems. Even though the attack is from high tonnage vehicles with high speeds, it's not possible for the vehicle to keep on moving because of the damage given to front, wheels and the bottom of the vehicle. RS Security Co.,Ltd road blockers are designed to K12 standards. Finite element model analyses are available upon request. Drive unit is electro-hydraulic, but in case of power failure road blocker can be lowered or lifted manually with the help of hand pump. Typical raise/lower time is 3 seconds. In case of emergency, raise/lower time can be as low as 1.5 seconds. With the help of PLC (programmable logic control), raise/lower function can be achieved by every kind of card readers, biometric readers like fingerprint or hand shape, radio control, on/off key switch etc. Besides, safety accessories like photocells, inductive loop detectors, flashing lights or red/green traffic lights can be integrated to the system very easily. Typical weight of a road blocker is 2-2.5 tons (depending on road blocker type).
