360 Degree Ceiling Mounted Hidden Recording Jammer for Meeting use
This hidden recording jammer is developed by our company according to the needs of users. It’s with two different types: ceiling and hanging, which are respectively suitable for different walls and scenes. The ultrasonic transducer puts in the metal mesh, ensuring the shielding effect and concealment. Each product is equipped with 20 ultrasonic transducer, with 2-5 meters shielding radius. The shielding angle is 45-60 degrees around the vertical center, forming the shielding area similar to the horn, as shown in the figure below:
The appearance of the product is the shape of Ceiling Speaker, which can hidden well when using. To distinguish the two types, we named the ceiling type as 20CH-L, while the hanging type as 20CH-L.
1. Ceiling mounted, space saving, good concealment.
2. Remote control switch, easy to operate.
3. Wide range of signal coverage: 90-120 degrees.
4. The shielding effect is better when the signal direction is 90 degrees with the recording equipment.
5. Step-less power regulation, controllable at any time.
6. The shielding distance is 2-5M (different recording equipment will be different).
7. Signal concentration does not affect people's normal communication.
