1. Please download IP Camera  on you computer . Download link : https://www.vstarcam.com/software-download
2. Then make sure your camera and computer work at the same network .
3.  Then open IP Camera Finder to detect your camera IP address .  
If the tool detects, please double click on IP address , then you will enter into Web browser , you need to input camera username and password .

Dear customer
Thank you for your feedback!
--- 2 note ip 192.168.1.4 , it is not work cam--- Is this camera fault one ?
If you cannot open IE browser and input username & password , the camera may get something hardware problem .
If the camera warranty is under warranty , please directly contact your seller to do a warranty . Sorry for inconvenience caused!

ip 192.168.1.4 , yes this is ,   

It ok , thank for you support .

If the connection is poor, the connection lasts and lasts. Try taking router nearer to camera or use cable connection. Then connection is fast and instant.

\n\nA similar problem, the camera c16s. The 64gb memory card is formatted in fat32, default settings, connection via wire to a PC or Router, the result is the same, there is no video.

\n\nHello, Sirs!
I have the same problem with this camera. Ok, it is old model, but almost not used. So I am looking for some support if this camera is good, I want to buy newer models. I tried from eye4 Play Market. Connected succesfuly. No video. eye4 for Windows - no video. app finder - nothing is found(some minutes). I started other apps. tinyCam Monitor - camera connected as ONVIF - no video, VsCam - no video.
All connected by LAN to my Sercomm router. ONVIF device manager, logged-in - no video, found HTTP port number-> Internet Explorer -> IP address works finally- installed ActiveX -> logged in to WEB interface, can control PAN and TILT, hear the sound through camera microphone, NO Video.
Is something wrong with hardware or it is possible to fix firmware?
