What is the infrared sensor (PIR) sensor?
The near-infrared applied is close to visible light, so it is only transmissive to the transparent body, which seems to be wireless to humans.
Therefore, it is a technology that can not pass through the opaque body, so it can be blocked due to fallen leaves, weeds, frost,
snow, fog, sea fog, and light scattering in addition to humans on the transmission line and can be mistaken for an alarm.
What about microwave radar sensors?
Using a 24.125 GHz frequency, the wavelength is long and electromagnetic waves pass through completely non-permeable objects such as humans (liquid),
high concentrations of liquids, metals, etc., without being blocked by deciduous leaves, frosts, snow, and fog, generating accurate alarms without misinformation.

DND-200D(TX/RX Barrier Type)
(snow, rain, fog, storm, etc.) function
- All-in-one functionality
Small animal avoidance (PET Immunity)
· The detection speed and the size of the object to be detected can be adjusted by adjusting the Signal function to suit the environmental
conditions of the site, without being affected by small animals, fallen leaves, or fog.
· The antenna module is a hardware technology product that determines the detection area and detection angle.
It is an object pattern analysis technology that determines the optimal signal by analyzing, organizing,
and calculating signals that output various characteristics of the natural environment such as the size,
rain, snow, wind, sensor-to-object distance, and speed of the antenna module.
DND-200D(station type)
A two-station sensor that monitors the level at which the transmission wave output from the transmitter has arrived at the receiving unit, and when the radio wave is blocked by the intrusion and the receiving unit level falls below the set threshold value, it is detected as an intrusion.
- ·It consists of a transmitter (T) and a receiver (R), and when mounted facing each other, it detects up to a range of 200m.
- ·The width of the sensing (protection) zone varies with the distance between the two devices and the selected system in sensitivity.
- ·Microwave Barrier DND-200D uses state-of-the-art microwave technology to detect when intruders break into a protected area.
- ·It protects a wide range of protective boundaries and is easy to install on any type of fence or pillar to prevent hard barrier protection and all activities around the boundary.
- ·It is developed not to sound alarms caused by small animals such as birds and cats as an original way to remove false alarms.
- ·It is remotely adjustable.
DND-30L/30W, 60L/60W, 90L/90W, 120L/W
(independent Intrusion Monitoring Sensor)
The detection range depends on the antenna angle of the sensor, and one sensor can cover a large area and detect intrusion locations, so you can set intrusion detection and non-detection areas.
- ·It can be controlled with intelligent digital technology using the Radar Sensor Module.
- ·It can be divided into 12 zones (2.5/5.0/7.5/12.0 x12) and can control and release any zone you want (only the entrance can be alerted and alerted)
- ·The signal is leveled regardless of the detection distance, so it is stable and there is almost no malfunction.
- ·Remote adjustment is possible with RS-485 communication.
- ·It has an anti-masking function.
- ·It has PET Immunity and natural environmental immunity (eye, fog, storm, etc.).
- ·It has a high voltage fault avoidance function.
- ·Suitable for security boundaries in various terrain (screen barriers, valleys, flatlands, etc.).
- ·Certification : KC Compliance Certification (Wireless Device), Saline, Spray, High/Low Temperature, Temperature/Humidity.
- ·IP65(DND-30/60/90), IP66(DND-30/60/90 Premium)
