This review is from: AVerMedia NV6480EXP 16 x BNC PCI-Express DVR Card
Pros: Overall features are plentiful. PCI-E 1x slot and stackable to 32 channels in true hybrid. Multi-screen compatible. Watchdog cable for unattended restarts. Free software upgrade for IP cameras and base software. Easy UI and pretty simple to learn.
Cons: Software compression. 42 megapixel limitation per computer system now. Output video and snapshot resolution is 1900x1200, so 5MP camera images are bottlenecked. MPEG4 conversion is dreadfully slow on large video files (AVI is faster, a lot faster). Software features and information is lacking, but this is an Avermedia issue. Version 7.7SP1 has new features, but no documentation on their website.
Other Thoughts: Have two of these cards side by side in the following computer box.
Lian Li PC-A70B Full Tower case
Gigabyte Mobo GA-EP45-UP3P
PC Power PPCT860 860watt PSU
Intel Quad Q9550 Yorky running at stock 2.83GHZ
Corsair Dominator 4GB (4 x 1GB) DDR2 1066 Twin2X2048-8500C5D
EVGA 512-P3-N973-TR 9800GT Video card
Plextor 22X DVD burner PX-850A
1 WD Caviar SE16 WD5000AAKB 500GB OS/Saved Data
5 WD Caviar WD10001FALS 1TB Drives for video footage
If you are going MP IP cameras 3-5 be mindful of the 42MP software limitation. Avermedia support says it is a limitation of the chip on the card itself, but who knows what the real story is. Simple enough to build another computer and run two standalones, or pipe them into a third for their CMS3000 software. Video is off a 5.0MP IQeye 755
