Wireless Communication Equipment Detector
First of all, thank you for choosing the examination room safeguard series product of signal detectors. “Examination room safeguard”- examination room cheating equipment detector is the new-type and high-tech examination room electronic and technical protection device specially researched, developed and manufactured for the phenomenon of using wireless invisible headset and wireless handheld communication equipment to cheat in the examination.
The signal detectors adopts electromagnetic induction and detecting technology, which can detect the electromagnetic wave emitted by the invisible headset emitter and the electromagnetic signal of every frequency channel sent by the communication equipment and accurately locate. It can stop the illegal use of various mobile communication equipments in the examination room.
2. Main characteristics of cell phone jammerVarious wireless invisible headsets can be accurately detected by signal detectors
Various types of wireless communication equipments (cell phone, intercom, high-power vehicle radio station, wireless pinhole camera, wireless video communication equipment, Bluetooth wireless communication equipment, various self-made communication equipments and radio and so on) can be detected and located by signal detectors.
Inductive passive detecting technology with no electromagnetic radiation for signal detectors.
Surface-mounted IC circuit design with low energy consumption and extra-long standby period.
Intelligent signal analysis disposition software is inlaid in the single-chip machine with timely and accurate precaution alarming for signal detectors.
Firmware supports to upgrade the software to suit to future needs of detecting for signal detectors.
Gaining of extra-strong signal is enlarged and the weak signal can be got sensitively.
The specifically short-distance disposing circuit with accurate and exact intensive crowd location.
High-quality monitoring signal input to support to obtain the evidence by recording.
Eight signal level strength indications with vibration and mute precaution alarming supported.
Humanized thin-film and micro-touch panel design is easy to operate and clear to indicate with strong directional sense.
3. Product specification of signal detectors
Detecting range >= 100 m2
Pre-alarming range >= 12.5 m2
Direction identification ＜ ± 15 degree
Sensitivity of signal detectors: 6dB
Pre-alarming notice of signal detectors: Level 10 LED + displaying + vibration alarming
Power supply of signal detectors: two pieces of AA batteries (No.7 battery)
Working current of signal detectors: ＜ 50mA
4 Method of use of signal detectors
1. Open the package of cell phone jammer, take out the machine, open cove of battery case at the back of machine, install batteries as per the correct directions, put the battery case cover back, insert the headset into the jack of headset and put the headset on.
2. Switch on the power supply of signal detectors and then the power supply light will be on. The equipment will be in the working status after self-inspection and then pre-alarm.
3. Hold the signal detectors in the hand, make an inspection tour in the examination room, observe signal change of display screen, adjust equipment direction and determine where the cheating equipment locates according to the displaying signal strength and voice strength being monitored.
4. If the signal voice in the headset is increasing during moving and signal strength indication value on the displaying screen is full, it means the cheater in within the range of 1m.
5. Press the gain button of signal detectors to perform the accurate location.
When someone uses such electronic communication equipments as the cell phone, intercom and so on, the detector will also pre-alarm with the same operational principle.
