Perimeter Security system wireless solar power photoelectric beam system installing instruction. Video guidance and user manual for setting up solar power beam system for outdoor yard, wall, balcony security protection.
The installation and use of 8-beam solar infrared beam mainly involve the following aspects:
1. Installation method: The installation methods for infrared beam include pillar installation and wall installation. In pillar type installation, the shape of the pillar can be 1-shaped, Z-shaped, or curved, and the key is that the pillar must be firmly fixed without displacement or shaking. Wall mounted installation supports direct installation of probes on the outer walls, walls, or fences of buildings, providing a horizontal 180 degree all-round angle and a tilt angle of more than 20 degrees to reduce false alarms.

2. Installation location: In order to reduce false alarms, the infrared beam detector set on the channel should generally be at least 50cm above the ground. The infrared beam set on the fence can be installed on both the top and side. When installing on the top, the beam should be 25cm higher than the fence or the top of the fence to reduce false alarms caused by birds, cats, etc. Side installation refers to installing the probe on the side of the fence or enclosure near the top, which can avoid interference from the activities of birds and cats.
3. Technical parameters: The anti false alarm ability of the 8-beam infrared beam is stronger than that of the dual beam, and the dual beam is stronger than the single beam. The shading time should be adjusted to a faster position to respond quickly to illegal intrusion.
How to debug the infrared beam? Let's learn about it below.
1. Adjust the optical axis of the infrared beam projector of the infrared beam alarm. First, we open the cover of the probe, aim our eyes at the sight, and observe the situation inside the sight. The optical lens of the probe can be adjusted left and right within a range of 180° by hand. Use a screwdriver to adjust the up and down adjustment screws under the lens. The lens system has an adjustment range of 12° up and down. Through repeated adjustments, the impact of the other detector in the sight falls into the central position.
During the adjustment process, be careful not to cover the optical axis to avoid affecting the adjustment work. The adjustment of the optical axis of the projector has a great influence on the sensitivity performance of the defense zone, so be sure to adjust it carefully and repeatedly according to the correct steps.
2. Adjust the optical axis of the infrared beam alarm receiver. Perform preliminary adjustment of the optical axis of the receiver in the same way as in "Adjustment of the optical axis of the projector". At this time, the red warning indicator light on the receiver goes out, and the green traffic indicator light stays on without flickering, indicating that the overlap of the optical axis of the head is normal, and the functions of the projector and receiver are normal.
Step 2: There are two small holes on the photoreceiver, marked with "+" and "-", which are used to test the infrared intensity felt by the photoreceiver. The value is expressed in voltage, called photosensitive voltage. Insert the test lead of the multimeter (red "+", black "-") to measure the photosensitive voltage of the photoreceiver, and repeatedly adjust the lens system to make the photosensitive voltage value reach the limit, so that the working state of the probe reaches the appropriate state.
Note: The four-beam detector has two sets of optical systems, which need to cover the upper and lower lenses of the receiver respectively, and adjust the upper and lower photosensitive voltage values until they are consistent. The two sets of optical systems of the ancient four-beam detector are adjusted separately. Because it involves the correspondence between the four optical systems of the transmitter and the receiver, it is quite difficult to adjust and needs to be adjusted carefully. If handled improperly, false alarms or protection dead zones will occur. The ABH four-beam detector integrates the two parts into one procedure, making engineering construction easier.
3. Adjustment of the shading time of the infrared counter-radiation alarm . There is a shading time adjustment knob on the light receiver. Generally, the shading time of the probe is adjustable between 50m/s and 500m/s. When the probe leaves the factory, the factory adjusts the shading time of the probe to a standard position. Under normal circumstances, this position is a relatively moderate state, taking into account the environmental conditions and the characteristics of the probe itself, so there is no special reason and no need to adjust the shading time. If we need to adjust the shading time for defense reasons to adapt to changes in the social environment. Generally speaking, the sensitivity of the probe is faster when the shading time is short, but it is more sensitive to objects such as fallen leaves and flying birds, which increases the possibility of false alarms. On the contrary, the longer the shading time, the lower the sensitivity of the probe will be, and the possibility of missed reports will naturally increase. Engineers should adjust the shading time according to the actual needs of defense.
4. Link the infrared counter-beam alarm to the anti-theft host. After the probe is installed, connect the anti-disassembly switch to the input circuit of the protection area. After the connection is completed, cover the probe housing and tighten the fixing screws. It is required that the warning light set for this zone on the anti-theft host does not flash or light up, and there is no alarm system indication output in the zone, indicating that the entire zone is set normally. Otherwise, check the circuit, re-debug the probe, and re-determine the status of the warning zone.
5. Test the anti-theft performance of the infrared intercom alarm. After the defense zone is working normally, according to the requirements of the defense, use objects of all possible sizes and shapes similar to the defense, use different speeds and different methods to block the optical axis of the probe, and use a wireless intercom to contact the control center at the alarm site to check whether the alarm is normal. At the same time, pay close attention to whether there is flashing or unstable state on the alarm host. In order to avoid leaving hidden dangers to the alarm system, this process is called the firing test. The purpose of the firing test is to test whether the infrared intercom alarm has the ability to alarm normally, whether the protection range of the defense zone can meet the predetermined requirements, and whether there is a protection dead zone.

The working principle of active infrared alarm is that the transmitter emits infrared rays of a specific frequency, which are then received by the receiver. When an object blocks the infrared rays, the alarm mechanism will be triggered. Then, its effective working distance is affected by many factors.
From the perspective of the device itself, the power of the transmitter is one of the important factors that determine the effective working distance. Generally speaking, the greater the power, the farther the infrared light can travel, and the corresponding effective working distance may be longer. For example, some high-power transmitters may be able to achieve an effective working distance of tens of meters or even hundreds of meters under ideal conditions. However, having a high-power transmitter alone is not enough, and the sensitivity of the receiver is also crucial. If the receiver's sensitivity is not high enough, even if the infrared light emitted by the transmitter can travel farther, the receiver cannot accurately receive and identify weak changes, and the effective working distance will be greatly reduced.
The impact of environmental factors on the effective working distance cannot be ignored. In a clear, unobstructed outdoor environment, the propagation of infrared rays is relatively smooth, and the effective working distance may be close to the theoretical value of the device. However, if there is heavy fog, rain, snow and other weather conditions, the infrared rays will be scattered and absorbed by suspended particles in the air, resulting in a significant shortening of the effective working distance. For example, in foggy weather, an active infrared alarm that could have an effective working distance of tens of meters may actually have an effective distance of only a few meters or even shorter. Similarly, in an indoor environment, if there are many obstacles, such as furniture, partitions, etc., they will also block the propagation of infrared rays, limiting the effective working distance.
Different application scenarios also have different requirements for effective working distance. For example, in a small family courtyard, only a few to ten meters of effective working distance may be needed to meet the needs of safety protection. For some large factories, warehouses and other places, tens of meters or even hundreds of meters of effective working distance may be required to achieve comprehensive monitoring. This requires choosing the appropriate active infrared alarm model and configuration according to the specific scenario.
In addition, the installation method and angle will also affect the effective working distance. If the transmitter and receiver are not installed correctly and there is a deviation in the angle, the propagation path of the infrared light may deviate from the expectation, resulting in a reduction in the effective working distance or a blind spot. Therefore, during the installation process, it is necessary to strictly follow the equipment manual to ensure that the transmitter and receiver can be accurately aligned to achieve the effective working distance.
In short, the effective working distance of the transmitter and receiver of the active infrared alarm is a complex issue, which is affected by many factors such as the performance of the device itself, environmental factors, application scenarios, and installation methods. When selecting and using active infrared alarms, we need to consider these factors comprehensively so that we can give full play to its safety protection role and provide reliable protection for our living and working environment. At the same time, with the continuous advancement of technology, I believe that the effective working distance of active infrared alarms will be further optimized and improved in the future, bringing more possibilities to the field of safety protection.
