Need IPCam to record video and audio across the street

[BakCompat]

I've currently got a range of IPCams scattered here and there at multiple locations, including Dahua 4300s, Panasonic BB-HCM581 (love this model), Ubiquiti, Linksys, etc etc

My primary work NVR is Blue Iris with mostly Dahuas on it. My boss wants to add an IPCam at his home to record the neighbor house across the street, both video AND audio. Apparently the police have paid them multiple visits. So I need a camera with decent outdoor audio recording capability. I'm not personally expecting much here, particularly for something under $200 or so. Any recommendations? A 1080p max res is fine, so 2mp is ok. I'll have to drop the data rate and framerate enough to make the datastream small enough for him to upload it over his home internet connection remotely to the Blue Iris NVR. As such, the audio would need to be encapsulated in the data stream, not a separate audio cable run back to a local machine.

I like the quality of the Dahua 4300 series for their price point, and that Huisun looks pretty cool, though not yet proven. Of course, I need audio recording here too.

So, any recommendations?

There is Dahua mini ptz with built in microphone. Looks like a great cam, but not really outdoor rated if you need that

Dahua turret which I owned briefly had really good microphone:

Huisun has option for audio input, but it's external

Oh and Huisun is proven. I've bought 7 of them so far, just minor issue with POE which I worked around.

You can find a camera with an audio input and add a parabolic mic... may be a little obvious, but you can hear a conversation from a great distance that way.

check out this one, you can get it with 12mm: https://www.ipcamtalk.com/showthread.php/9954-Dahua-IPC-HFW4421D-AS-Audio-4MP-HD-WDR-Network-LXIR-Bullet

it has audio input, with my powered microphone I could pickup an argument across the street pretty easy.

Ok, I like both cameras but what about preferences for an external microphone if thats what he prefers?

here are photos of me hooking a powered mic up to the IPC-HFW4421D-AS, https://www.ipcamtalk.com/showthread.php/10299-How-To-Audio-Inputs

and of course wires can be extended so you could mount the mic in a more suitable location if nessicary.. thats the advantage to external, with internal your kinda stuck with what you get.. external you can always work to make it better.

be aware its not always legal to record audio without BOTH parties permission.. several states/countries have laws on this.

how about bolting one of these:

to the top cover on a huisun/imporx 10x mini-PTZ w/ audio:

and place the microphone where they show the cigarette tip:

the dish would help filter out audio not in the line of sight of the camera (by augmenting the sounds that are)
no matter which way you aim it...

expanding on what Nayr mentions, from Wikipedia fwiw:
<quote>
Laws differ in the United States on how many parties must give their consent before a conversation may be recorded. In 38 states and the District of Columbia, conversations may be recorded if the person is party to the conversation, or if at least one of the people who are party to the conversation have given a third party consent to record the conversation. In California, Connecticut, Delaware, Florida, Illinois, Maryland, Massachusetts, Nevada, New Hampshire, Pennsylvania, Vermont, and Washington State, the consent of all parties of the conversation must be obtained in order to record a conversation.

now, I suppose something like a fight or an explosion may not fall under the same rules as a 'conversation' per-se.
Could one conceivably argue that a clearly visible sign indicating that video/audio recording is in progress constitute 'consent'
on the part of anyone in the area? sticky-wicket, this audio recording stuff...
