Product Description
      Waterproof Cell Phone Signal Jammer


HDT-994 is a High Power Indoor/outdoor Water-proof Cell Phone signal jammer, implementing the most effective and reliable RF jamming technology to prevent the leak of confidential information or unwanted usage of cell phones, Wi-Fi devices and Bluetooth devices.
HDT-994 has 8 sets of jamming signal generators inside, which can transmit highly effective jamming signals targeting all cell phone and Wi-Fi devices within the blocking range. Once you turn the jammer on, with the help of its high-gain omni-directional antennas, 994 can jam continuously and simultaneously, all the RF communication Frequencies 860MHz~2665MHz which are most commonly used by cell phones and Wi-Fi devices. Adopting the latest jamming technologies, HDT-994 jammer features ultra-high RF transmission power, making a stable shielding range around.

Once the system is activated, it transmits unique noise signal which creates "Firewall" between the transmitter and its receiver (cell phone and Wi-Fi device).
Besides, HDT-994 can prevent the leak of confidential information leak via cell phones or unwanted GPS location leak.
