[Widely used in] Specially designed for convention and exhibition center, large-scale activities, courts, prisons, tourist attractions and public places such kinds of security checking occasions.[HIGHLIGHTS]  ⊙Detecting area: Six vertically distributed detection areas,transmit and collect singles from both sides. Objects being detected can be accurate positioned.  ⊙Recognition function: No blind area within uniform detecting area. The highest sensitivity is capable for detecting paper clip-sizemetal  ⊙The sensitivity:Free adjustment within 200 sensitivity levels and separated adjustment for certain detecting area are available. According to different checking parts to exclude detection of coins, keys, jewelry, belt buckle, etc.  ⊙Detectability: The infrared correlation device, automatic tracking& sampling adjustment technology speed up the induction detecting.  ⊙Alarm display: LED at both sides displaying and alarming the contour points of human body, and more than one alarms simultaneously is available.  ⊙Alarm sounds: 10 kinds of alarm sounds for choice, 10 volume for adjustment, 1 ~ 19 seconds optionalfor sound isolation setting.  ⊙Anti-interference ability: Adopt the most advanced technologies of digital filtering, digital pulse and magnetic-electric compatible. No interference even multiple devices used at the same time.  ⊙Strong signal attenuation: High sensitivity and under control of infrared correlation, it can alarm properly without omission even oversized metal passing through.  ⊙EncryptionManagement: Sensitivity parameters Settingsis available only after inputtingcorrect password.  ⊙Data recovery: Once data loss caused by improper operation. Please reset to default according to password provided by original factory.  ⊙The computer control: Parameter settingand detecting data display are available through computer.  ⊙Networking: Can connect with computerthrough reserved data communication interface. And many sets of device can be connected and controlled simultaneously.  ⊙Lightning protection design: Device is designed with electric tube and znopiezoresistor combination module, and can be used under "exposure environment"  ⊙Resistance to impact: Device is featured with strong resistance to impact and touch attack ability.It will notbe influenced by external factors during normal standby.  ⊙Stability: Distortion-free epoxy board is the base board of probe coil, which ensures the stability long service time of the device.  ⊙Safety: In accordance with the current international safety standards, by adopting the technology of weak magnetic field, the heart pacemaker wearer, pregnant women, CD, film, video, hearing AIDS, etc. No damage  ⊙Water-proof design: Import waterproof synthetic fiber materials, precision machining (door foot cases are more than 50 mm) of the production process[Specifications]  Working voltage:AC 220V  Power:35W  Working environment: -30℃-+60℃  Overall dimension: 2200mm(H)×870mm(W)×650mm(D)  Tunnel size: 1980mm(H)×750mm(W)×650mm(D)  Weight:about 75kg
