Is it possible to setup one Dahua ip camera to my network without a nvr by using smart pss, but still use the Dahua mobile phone app iDMSS and access playback via phone with push notifications etc? Or do I need blue iris?
Blue Iris is the best option...but you can install an SD card into the camera, record to it, then retrieve the video from the SD with either IDMSS, SmartPss or the Web interface of the camera.
