Dahua NVR Channel Question

[LopezEL]

My brother is ordering a couple of these dual "booby" cams:

I have one of those and added it to Blue Iris but he is wanting to use an NVR (haven't been able to convince him otherwise).
If he orders 4 of those booby cams and another single camera such as a 5442, will an 8 channel NVR suffice or will he need one that supports 9 channels?
I'm not sure how the NVR categorizes the dual camera?

Andy told me to order this but it's only an 8 channel: Amazon.com: Loryta NVR4108-8P-4KS2 8 Channel Smart 1U 8PoE 4K&H.265 Lite Network Video Recorder English Version

@looney2ns may know for certain, but I'm 99% sure that would be 9 channels.

Thanks.... I actually convinced him to go with blue iris. Just ordered him an optiplex with an i5 6500 from ebay.

Yep the booby cam counts as two cameras in an NVR. Blue Iris is a good choice - you will need to make sure to select camera one and then copy that camera and then select camera 2 to get both feeds.
