One thing I really like about Amcrest is that they do not try to lock down their products and trap you in their ecosystem. Since the NVR supports the ONVIF standard, you can add any 3rd party camera from manufacturers like Hikvision, Dahua, Sony, Vivotek, and even Foscam Amcrest’s nemesis whom they had a falling out with and the reason for the Amcrest brand being created. The camera included in this kit appears to be the IP2M 842EB model, which can also be purchased separately. These are 1080p 2MP IP cameras that ca do night vision and have a very good IP67 weather rating. They are also ONVIF compliant so can be used with ONVIF compliant NVRs or a DIY NAS NVR system if you have one. Using the Amcrest smartphone app, you can login to the NVR at any time to see a live feed of all the cameras as well as recordings. See the full datasheet of this NVR hereopens in new tab.
