IP Camera with 2-way Audio - setup

[yeswife 0]

Hello all,

 

So I finally managed to get all my cameras working with the speaker and microphone at the camera location.

 

Just abit of background on this. I wanted a mini speaker & microphone mounted next to the camera and login anywhere with iDMSS to view it and have 2-way communication.

 

1, Managed PoE Switch must be connected to a Router with DHCP enabled

2, Cams are connected to the managed Switch - any port. - disable DHCP

3, NVR is connected to same managed switch - any port. - disable DHCP

4, Locate the cameras IPs by login into the router or switch - the router should auto assign them with different IPs. ensure your Switch and Router are two different IPs aswell. eg 192.168.0.50 for the router and 192.168.0.99 for the switch.

5, Login to each camera with its own IP and the NVR to enable DDNS, I used Dahua DDNS select Manual Mode and select your own domain name.

6, Login to your router and enable Port Forwarding, use only TCP as the Protocol, and ensure you enter the IPs of the cameras and the NVR, if you cant select multiple ports, change each of your camera ports and add them into the port forwarding list of the router, example if NVR is on port 37777, camera 1 port 37778, camera 2 37779 etc.

7, Test if the internet have access to this these ports on here http://canyouseeme.org/

8, Add the devices on the iDMSS app using IP/Domain ensuring you are using the correct DDNS name and port.

 

Now with the above steps completed correctly, you should be able to view the cameras and the NVR(for playback) anywhere as long as you have internet access.

 

For the audio, since my cameras have both Audio-Out/In, I have a small amplifier connected to Audio-Out port and attached to it is a small speaker. https://www.kemo-electronic.de/en/Light-Sound/Amplifier-Splitter/Modules/M031N-Amplifier-3-5-W-universal.php

 

And as for the microphone, I tapped of the 12v and connected to the Audio-In port.

You can buy these from ebay for pretty cheap.

Any questions, please ask.
