I'll say generally that it depends on your site lighting. I'll give a couple examples. I have a 50' long interior corridor that I had a camera with an ExView chip monitoring. With no interior lighting except the red "exit" signs at both ends, the ExView chip could still render a viewable picture, but the light coming from the signs was enough to cause video noise that my GeoVision DVR interpreted as motion. Switching to a SuperHAD chip in that location resulted in a darker picture when the lights are off, but more accurate motion sensing when the lights are on. I have exterior cameras with ExView chips, and had one on a rear driveway which is illuminated at night with sodium "wallpack" commercial lighting. Again, the light combined with the ExView chip was causing large amounts of "video noise" = "motion". Adding some additional light close to the camera location overcame that issue. So my opinion is that if your location is really dark at night, the ExView cameras are a good choice. If you have a decent amount of light, you can probably get away with SuperHAD.

I know this is a CCTV camera forum, but has he considered moving to prepay-only pumping? Most of the stations around here are now on a prepay system. Just to complete the thought, I own a self-storage facility, and I have lots of cameras and lots of disk space in my GeoVision box, but my facility is still fenced and I have a coded access gate for people to get in and out. What I'm saying is that it's nice to capture video evidence, but it's even nicer to prevent the theft in the first place.

I have several of their (older) ADH-SDN400 armor dome cameras and some of the newer A200M armor domes. I liked the housing on the ADH cameras better...easier to plug in a camcorder and do "on-the-spot" aiming. With the A200M cameras, in order to keep the power/video leads "enclosed", I had to put on an extra conduit box that makes local adjustment a little more particular. Watch their specs carefully...their products that specifically say Sony SuperHAD or ExView are, the ones that say Sony day/night are something else. The ADH-SDN400s handle low-light better than the A200Ms. I have decent site lighting, so it's not much of a problem. Anyway, they are decent for imported product. They seem to be changing their focus from end-user service to distribution to installers only...I found them on eBay at the beginning of the year, about 2 weeks ago when I was doing an exchange, they told me they wanted me to do dealer paperwork because they weren't going to be doing end-user accounts anymore.

Hello - long-time lurker, first time poster. I have a GeoVision 7 system and just installed an additional hard drive. Windows XP sees the drive and reports that it is working properly, but GeoVision doesn't see the additional drive space. The GeoVision manual doesn't offer any information on utilities to configure additional drive space, so I'm looking for wisdom from the board...how do I make GeoVision see the additional space I just installed? Thanks in advance.

OK, thanks for the confirmation that there wasn't a more "automatic" way to do it. Good to know that I don't need to replicate the entire folder structure...I'm sure that I will be adding additional drives in the future.

OK, I went to the new drive and created a folder structure similar to my other data volumes, with a "data" folder and then "cam" subfolders, and then went into setup and set the new "data" folder as a log path. This increased my available storage space. Hopefully this was the correct way to go about this...kinda kludgey in my opinion...but I'll be adding more drives in the future so hopefully this was the correct way to go.
