Hikvision video intercoms
Forgot your password? By jp , November 9, in Installation Help and Accessories. The camera then has a horn speaker connected to an audio output. The camera is then wired back to a Hikvision NVR. The sound from the Mic works fine when the speaker isn't being used. As soon as the push to talk function on the IVMS app is used a lot of feedback happens through the Mic.
The app doesn't have an audio cutoff for the microphone built into it when you use the talkback functions. I have used functions in the camera for echo noise cancellation and tried adjusting microphone levels in the camera. Currently, the speaker is about 5 meters away from the mic and have been trying to come up with a way to reduce the feedback on the microphone without massive loss of quality.
Ideally, the speaker isn't wanting to be moved so if anyone has any thoughts on how I can get around this. If you move the speaker or the mic it should eliminate the problem for instance have you ever been in a meeting room with overhead speakers and someone is speaking into a mic and you get that squeal. If the mic is moved a few feet away the feed back goes away as the speaker is too far away to act as a microphone.
Audio feedback is caused by an acoustic loop. There are a number of ways to address the problem. The volume can be set to below the feedback threshold which in itself will depend on a number of factors. The physical orientation relashionship of the speaker and microphone can be changed to decrease the level of signal received from the speaker. The immediate environment can be changed to reduce or dampen the audio reflection from the speaker. This inserts either a small time delay or a phase delay in the signal to break the resonance loop between input and output in high gain amplification.

Hikvision DS-2CE76D0T-ITPFS 2 MP Audio Camera
Having a two-audio through your Hikvision security system may improve your overall security. Hikvision IP cameras that end up with a —S on their model names support audio function, for these kinds of cameras you can get not only the live video but also the real-time audio. Two-way audio could be used for only one camera at a time. Some cameras such as DS-2CDF-I W have an internal built-in microphone and speaker, however, for most Hikvision IP cameras, external microphone and speaker are required to be added separately. Hikvision IP cameras have different audio placements on their motherboards.

Hello, I have question. Hope that helps. A brand other than Axis, thnx. I will look into this for you using some of the NVR's we have around the office and update. We've also forwarded your question to Axis, I will update if they give any feedback. Not certain there are any NVRs that it would be compatible with unless they have special drivers. There are many VMS to select from where it will function. Not certain.
Anyone got 2way-audio with a Hikvision camera?
