I have two Geovision NVR systems & two 3rd party usb dongles. I am in the process of getting rid of an analog 1480 card to dump some older motion sensor (PIR) style cameras for some IP Onvif ones.
I have two locations & 20 cameras per location for a total of 40. I am moving to the VMS platform as I think it will get more support & the usb dongles are cheaper.
I am looking to add some Hikvision cameras to the mix & was trying to decide if I should get them for $115 on amazon or $75 on ebay. Seems to be the same model but if Geo doesnt care about firmware then I should be OK.
I have a number of older geovision cameras (BL220, 120, etc) & they have been working great but I have always had difficulties getting the focus 100% correct as putting the lens cover on seems to bump them slightly out of focus (sometimes).
A BL220 died on me & I have been thinking of swapping it with a DS-2CD2032 (Hikvision).
The combo of Geovision NVR or VMS & IPcamviewer has been great for my usage style.
