Axis Cameras And Echo Cancellation

Goal (aka what the tree house should look like in the end): To have successful video and two-way (duplex) audio between a central location and 20 rooms utilizing Axis P3364 cameras. And to keep things consistent, let’s say I’m just connecting to each room as needed with an IE web browser.

Current state of the tree house: I have 20 rooms (approximately 14’x20’), each with an existing Axis P3364 camera, and one spare/unused PoE network drop.

Things I’ve tested: Installed a Louroe AOP-SP-CF. It’s basically a ceiling mount speaker microphone with a built in amplifier.

The speaker/mic is powered by a Louroe IF-PX (single zone PoE extractor with a variable gain adjustment and audio I/Os which connect to the camera).

Everything works great doing a push-to-talk solution, but when implementing a duplex setting on the camera, I get the dreaded echo in my ear piece when speaking from the web browser to the camera/room. Note: I’m using a headset on my PC to listen and to send my voice.

My next thought is the disconnect the microphone on the speaker/mic unit and install a separate mic 10 feet away from the speaker, but I haven’t done that yet. I have a feeling it will be the same result though. I also have a feeling that the responses will include comments that the Axis P3364 doesn’t have echo cancellation, and that I’m up a creek….but you never know unless you ask.

Looking for any thoughts or recommendations….or other products <you pick> to finish my tree house. Adding the Louroe gear mentioned above would be about $700 / room, but at this point functionality without echo may trump overall price.
