main features
NP-VA100D is a four in one device that integrates functions such as public broadcasting, audio monitoring, full duplex intercom, and alarm.
The built-in speaker, microphone, echo cancellation module, and alarm button can achieve real-time full duplex voice intercom.
Equipped with KaBoni advanced digital noise cancelling microphone, it can achieve voice intercom within 3 meters without echo whistling.
Adopting advanced digital AEC audio technology independently developed by SIZHENG can comprehensively eliminate echoes.
Adopting intelligent digital FPGA dual core wide dynamic noise reduction algorithm, it can pick up sound clearly in complex environments.
Equipped with 3W high-quality speakers across all frequency bands, the sound is loud and clear whether it's for intercom or broadcasting.
Built in anti distortion and anti distortion technology to maximize the protection of speaker output and ensure the fidelity of sound quality.
Can be matched with devices such as DVR, IPC, DVS, NVR, etc. that have audio input and output interfaces and support intercom function.
The public broadcasting system, audio monitoring system, IP intercom system, etc. that need to be designed and implemented separately in the weak current system integration can be centralized into a unified audio and video monitoring intercom system.
Equipped with RS485 bus control and compatible with the transmission protocol of network audio and video servers, it can achieve comprehensive information exchange with the control center, including initiating calls, coordinating addresses, etc.
The digital pickup distance is far, the long-distance intercom is clear and noise free, the broadcasting distance is far, and the anti-interference ability is strong.
The expansion has a recording output port, which can be used in conjunction with voice cards, hard disk recorders, computers, etc. to achieve synchronous recording.
Adopting high-end aluminum alloy brushed panels, including ABS fireproof installation base, the appearance is simple and elegant.
The product adopts support rods and hexagonal fixing screws inside, which have anti disassembly and explosion-proof functions.
The panel integrates a call alarm button, supporting alarm output and one click intelligent communication.
Provide multiple assembly structures, which can be embedded or hung on the wall, and can be installed openly or in a simple and convenient manner.
Suitable for working in ultra high ambient temperatures ranging from -20 ℃ to 75 ℃, ensuring high-quality voice intercom performance.
● Passed the EU Environmental ROHS Directive 2002/95/EC construction standards.
● Passed the EU CE standard and the highest inspection synchronous recording and video system construction specifications.

● Tested according to relevant standards of the Federal Communications Commission (FCC) and corresponding system construction specifications.
