What is an electronic fence sensor?

Electronic fence sensor is one of the most popular types of fence today, has the effect of protecting and supporting people in terms of security, security, anti-theft, …

At the same time, the electronic fence sensor is also considered an important step in the application of technology to solve the problem of safety and security for people. Through sensing objects and strange objects approaching your family’s living area, the device will give you danger warnings.

Working principle of electronic fence sensor

The electronic fence sensor is equipped with IP65/IP67 resistance standards, so it is suitable for outdoor installation, working areas in the home. The electronic fence sensor set is based on the following principle:

• Transmitter: Has the effect of projecting infrared rays at the receiver in a straight line to create a focused beam of light. The lens then focuses small infrared beams that are emitted through the LED. Finally, the infrared rays, when transmitted strong enough, will reach the receiver at a distance of 50-100m .
• Receiver: If the Transmitter emits a signal, the Receiver will receive the emitted signal. Here, the receiver will be equipped with super-sensitive sensors with infrared signals along with electronic circuit boards, working status indicator lights including: Level (with power supply) – Good (good signal reception) – Alarm (no signal received) . Then, the received signal will be sent to the alarm center with a signal cable through RF radio wireless waves.

How to install the fence sensor

Power supply for transmitter and receiver

The first step, for the fence sensor to work, is to provide power to the transmitter and receiver. When buying a fence sensor, the company will include an adapter or power supply for you, you just need to connect the power cord to the Power (+) and (-) pins respectively to be able to power them to work. Already. However, to ensure that the current is strong enough, pull the wires close to the power source or give them a separate fixed power source!

Connect the signal receiver to the hub

On the signal receiver of the product will be integrated 2 pins to connect 2 signal wires to the alarm center, please connect these pins according to the position marked Alarm , they include the following 3 pins:

• COM pin: At this position, connect 1 wire.
• Closed signal pins (NC), open signal pins (NO): On the product you buy will be accompanied by a user manual (HDSD) on how to connect the wire to the signal pin, please see the user manual for details on how to do this. Install for each model!

For wireless fence sensors, you need to power the center into sensor learning mode and block the signal in between the two transceivers so that the receiver can receive and send RF radio signals to the center. alarm. However, with this connection, you need to be supported to learn wireless sensors from the alarm center!

Install the sensor on the fence

On the market today there are many different types of fences such as walls, B40 nets, barbed wire or barbed wire fences, etc. Depending on the type of fence, we will have different installation methods:

Step 1: You create an empty space for the transmitter, the receiver can see each other and emit light. Then, you proceed to cut down the trees/canopy or items that obscure the path of the two infrared rays to ensure the sensor can work at its best, avoiding false alarms and false alarms.

Step 2: You install the electronic fence sensor on the desired position, but it is recommended to be at a height of about 0.5 m so that the machine can detect normal people and crooks. Fraudsters often break in at a height of over 1.6 m , so even if you stoop, it will still be higher than 0.5 m, so the machine will definitely give you an accurate warning.

Step 3: After successful installation, please test the alarm ability of the machine by climbing, jumping or crouching!

Some notes during installation

• You need to make sure that the power supply installed to the sensor is strong enough, not too weak or flickering or the connection wire is bitten by a mouse.
• At the same time, you also need to pay attention to the distance of the transmitter and the receiver when installing so that it does not exceed the specifications given by the manufacturer to ensure the effectiveness of the device.
• In addition, if you find any problems that are not guaranteed when you buy the device, please contact the supplier immediately for more advice!
