I am building a home security system using Rasberry PI, Can an you please help me fix the following situations
Problem Case 1:
I was trying to process the IP CCTV CAM(HIK VISION) video live stream inside R PI 3(Ubuntu Mate 16.04 & OpenCV 2.4) using Ethernet cable, I am able to get the video stream, but its very very slow(at least a five minute lag). Can you please enlighten me to understand the reason?
Problem Case 2:
I was trying to process analog CCTV Camera(HIK VISION) video live stream video live stream inside R PI 3(Ubuntu Mate 16.04 & OpenCV 2.4), but here, since I was told both DVR and R PI needed to be in the same network(Meaning: Similar IP Address), I had connected the DVR feed to wifi modem and I took the output feed from wifi modem to R PI 3, Please correct me, If this approach is wrong, as its very slow but working
Please also suggest me, If I need to change my approach in both the cases
