Our company uses a unique design to integrate solar alarm on solar street lights to solve the problem of providing lighting while providing security alarm functions. It is an independent outdoor lighting and alarm system integrated design. After installing the solar security street light, if a thief enters the guarded area, the detector will detect the infrared rays of the human body and immediately issue a harsh alarm sound to scare the thief and remind the host. It is widely used in various outdoor scenes, such as courtyards, farms, breeding farms, construction sites, factories, etc. The alarm has an independent remote control switch to control the opening and closing. When the user visits the scene, the alarm can be turned off when the alarm function is not needed.
For our modular design of solar street lights, integrating solar alarms has become very simple. You only need to install the PIR siren alarm on the front of our solar street light, and then connect the solar street light power supply. Once the installation is completed, the siren will work automatically, no need to set up and maintain, and the siren will be powered by solar street lights.
Solar security street lights use infrared detection technology. At present, infrared technology has become an important part of advanced science and technology. Since infrared is invisible light, it is used for infrared detection and monitoring, which has good concealment. It can be used both day and night, and its anti-interference ability is strong. Solar security street lights use ICU control technology to automatically detect intrusions that occur in the armed monitoring area, generate an alarm signal, prompt the area where the alarm occurs, and display the system that may take countermeasures. In the event of an emergency, the location of the incident can be accurately displayed in the security control center through sound and light alarm signals, so that emergency measures can be taken quickly.
The solar PIR alerter designed with sound and light indication, which can avoid external interference from sunshine, humidity, dust, insects and wind also. The detector adopts very advanced technology as below: direct analysis technology to intrusion PIR signal from digital high-speed micro-processor; dual-polarities detection, direct adjustment to digital signal sensitivity; filtering technology to mixed rays from multi PIR channels etc. In a word, it is stable in operation and advanced in function, combined with its IP-65 water proof design, it is suitable for operation in those areas needs sound and light remind such as forest, high-tension pole, park, warehouse and docks etc.
Solar alarm integrated street lights have the following advantages:
- Solar powered, no wiring required
- Intelligent human body infrared sensor
- 120DB sound and light integrated alarm
- Wireless remote control disarming and arming
- IP65 protection level
- High temperature resistance
- Alarm flash LED can be red or blue
- Alerter horizontal 180° and vertical 30°adjustment
Currently, there are two types of solar infrared alarms: active and passive.
The working principle of the active infrared detector: the active infrared detector consists of an infrared transmitter and an infrared receiver. The transmitting end actively emits infrared rays, and the receiving end receives infrared rays to form an infrared network. This kind of detector can actively prevent intrusions, and will not cause false alarms due to the passage of small pets or the influence of climate, thereby minimizing the false alarm rate. The infrared transmitter emits one or more modulated infrared rays to the infrared receiver. When there is no obstruction between the transmitter and receiver, the detector will not alarm. When an object is obstructed, the output signal of the receiver changes and the detector alarms.
The working principle of passive infrared detectors(what we are using): Passive infrared detectors rely on passively absorbing heat energy and the infrared heat emitted by the animal’s body to give an alarm. It is also called pyro-infrared probe. The detector itself does not emit infrared rays. There are two key components in a passive infrared detector, one is a Fresnel lens, and the other is a pyroelectric sensor. Any object in nature above absolute zero will produce infrared radiation, and the wavelength of infrared energy released by objects at different temperatures is also different. The human body has a constant body temperature, which is different from the ambient temperature. When the human body moves, the change of this difference is detected by the pyroelectric sensor through the Fresnel lens, thereby outputting an alarm signal.
