NVR security systems

I am not sure if this is the right forum to post this question. Anyway, I am interested in getting a 4 channel NVR security system for outdoor( Night vision if possible) that works for MAC OS and IOS devices.

I looked at Costco/Bestbuy's site and could not decide what to get. Any one has any input/advice, please respond. Thanks.

My house is just rebuilt and we have all the Ethernet port ready, I need the cameras with the POE ( power on ethernet).

Thanks.
