Questions and Answers
With these DVR's I have tons of functionality and configuration options using just the web interface, which is unheard of in economical systems. I don't have to purchase a dedicated Windows computer that isn't used for anything other than the surveillance software, and otherwise just takes up valuable desk space.
I am using two of these now, but have ordered another 10. I am swapping out all of our existing DVR's to make them consistent across all of our buildings. I am then swapping out the hard drives for bigger ones ... also an easy process.
I have to say that these are flexible ... we have mostly CCTV cameras, with a few high-end IP cameras in the mix as well.
Our CCTV cameras are a mix of models and resolutions. About half of them are fairly new 960H resolution cameras, while there are still quite a few that are older with varying models and resolutions, and a few are new 2MP CCTV cameras from a couple of different manufacturers.
These DVR's have handled all of them beautifully so far (even the IP cameras), which is more than I can say for the last two brands of DVR's we tried which cost us well over $1,000 each. These also are not 'laggy' like others we have used ... they respond quite nicely.
One note, these apparently can't handle more than 2 IP cameras on each one (mixed in with the analog cameras). So if you have all IP cameras look at an NVR. Oh, and if you need tons of front-panel functionality these are a little limited (we do everything remotely via the online interface).
Finally, I will say that there isn't a DVR on the market today that even comes to providing the functionality of these ... unless you spend 8X the money.
PROS: Easy to configure, but with tons of options if you want to dig deeper into the settings. Flexible. Responsive.
PROS: vga & hdmi outputs, PTZ ability, ability to add IP cams (2) if needed
CONS: as far as cons, trying to figure out how to get this to work on mobile devices was a pain, but now the issue is solved. The application for smart phone is Guarding Expert.
PROS: Works great, no fuss, no muss.
CONS: Wish the DVR came with an explanation that there's no programing needed, would have saved me an hour trying to figure out why it was already working.
