Thanks for the reply, but I really need someone to be very specific. You are saying port forward from the external WAN to the LAN interface of the CCTV, ok fine, but what should be allowed out from the internal LAN to the external WAN? AFAIK "Home" firewalls tend to block incoming connections, but often allow all traffic outbound, but business firewalls by default block traffic both ways, so rules have to be set to allow traffic to flow from the LAN to the WAN interface. So you are suggesting port forwarding from external WAN to the LAN interface of the CCTV PC, but what should be 'allowed' to flow from the internal LAN to the external WAN interface?

Geovision stopped selling GV-900 for at least 2 years ago. So either is it an old stock, used or a counterfeit, I havent heard of GV-900 CF so it could be an old one. All Geovision cards from GV-250 thru GV-800 (also GV-900 and GV-1000) is the same quality the only difference between the cards is number of video channels and how many frames per second they can handle. JD Thanks for the info. I didn't know Geovision cards were being cloned. I've already got experience of a cloned Kodicom card and whilst the speed of performance/stability is good, the video quality is very below par and unacceptable. Are Geovision being cloned a lot?

Sorry to repeat, but has anyone got any thoughts on the GV900? How does it compare to the current GV800 card? Can anyone tell me the pros and cons of it?

Guys, reading back through various threads, I can see the following information regarding ports for Geovision - 80 = h t t p 3550 = TCP Server (bind IP in "Hotline/Network" tab, Used for RemoteView Client) 4550 = Command 5550 = Data 5066 = Remote Playback Server 6550 = Audio 3389 = Remote Desktop Connection 3663 = Authentication Server Minimum ports for viewing remotely over internet explorer are 80/4550/5500 My question is, how should these be configured? For example some firewalls by default block only incoming connections, but some block both incoming and outgoing connections. Can someone detail exactly which direction the ports should be allowed? I'm assuming port 80 is forwarded from external to the internal ip address of the CCTV PC, but when what should happen to 4550/5500? Should they also be forwarded from external to the internal IP of the CCTV? Should anything specific be allowed from internal to external? Thanks

Guys, I'm also in a similar situation. I've got the chance to buy a Geovision GV-800. It has the two d-type connectors, but from a photo (which could be incorrect) it appears to match the type displayed in the "henry's" link posted earlier. The card is boxed/sealed with drivers, 2 x BNC tail leads etc. If it is an older version, is that necessarily a bad thing? What functionality will it miss? I've also seen a GV-900 for sale, but I don't think current Geovision sellers even sell this card anymore, is it a good card?
