Recently I’ve purchased 2 Hikvision DS-2CD2532F cameras. I’m really happy with them! I configured cameras and my router and can access them via internet using the Hikvisions DDNS system. I have installed the desktop client as well (iVMS-4200) and can access and control cameras over my LAN. Everything is working great and overall I’m very happy with the quality of the hardware and software. Right now 2 cameras are working with no NVR. I have ordered Qnap ts-253-pro which I’m planning to use as NVR and my NAS. My router is Asus AC68U and cameras are connected to it via Dlink 8 port POE switch. Never an issue connecting to cameras over the web browser whether on LAN or on internet. No issues with iVMS-4200 either and I do get email alarm notification with 3 pictures attached. My problem is that one of the cameras (Cam2) I can’t access 90% of the time using iVMS-4500 app on my android smartphone. The app says “Starting live view…” followed by “Error code: 152”. This only happens on one camera and that is the camera which I have mapped different WAN ports than the ones that are set up on the camera. Note that local ports have been left as default and for Cam1 I have forwarded those default ports without any changes. Here are my port forwarding settings from my Asus router: Cam1: 192.168.1.61, local port 80, WAN port 80, protocol: UDP & TCP 192.168.1.61, local port 554, WAN port 554, protocol: UDP & TCP 192.168.1.61, local port 8000, WAN port 8000, protocol: UDP & TCP 192.168.1.61, local port 443, WAN port 443, protocol: UDP & TCP Cam2: 192.168.1.62, local port 80, WAN port 8008, protocol: UDP & TCP 192.168.1.62, local port 554, WAN port 8002, protocol: UDP & TCP 192.168.1.62, local port 8000, WAN port 8001, protocol: UDP & TCP 192.168.1.62, local port 443, WAN port 8003, protocol: UDP & TCP What does error 152 mean? Does anyone have any experience with this kind of setup and can provide guidance on what can be done to fix it?
