Hi, After reading on this forum a lot i purchased Blue Iris and 6 Hikvision cameras for outside of my house. Really happy with the cameras but I'm getting a lot of false detections and want to interface some sensors to BI to activate recording and send alerts. Can anyone recommend best sensor without false detections for outdoors with a 12kg pet dog. Was thinking something that has dual PIR + Microwave. but being Im new to all this Im not sure what to get. Also i like this interface that has been mentioned in the forums a few times but is there something similar that could handle up to 8 sensors eI/O PLC-8 - Sealevel Also how do i power the sensors, is there a recommended product for that? Appreciate any help.
