ronp 0 Posted April 13, 2013 What's the difference between the CNB VBM-24VF vs. VBN-24VF? An online authorized CNB dealer has the N model on clearance? Are the specs the same/different? Features? Newer vs. Older? The item description states that the VBN-24VF has the RS-485 interface option. Is that standard on both? I do want that so I can adjust the menu settings from a cheapo PTZ Camera Remote Controller/Programmer (I do have an extra twisted pair to the camera). - Ron Share this post Link to post Share on other sites
Kawboy12R 0 Posted April 13, 2013 Just to confuse the matter- http://site.surveillance-video.com/pdf/VBN24VF-Specsheet.pdf http://site.surveillance-video.com/pdf/VBM-24VF-2G-Specsheet.pdf vbM is shown as having RS-485 optional but the vbN isn't. No mention of vbN on CNB's site for some reason, even in their discontinued product list. The vbN is shown in that spec sheet as having DSS and 3D-DNR though. Looks like a phone call or email to any site selling either to positively verify yes/no is in order if the RS-485 is important. CNB has even decided in their infinite wisdom to make the terms "Pelco" and "485" unsearchable in the vcM manual (they're embedded in pictures rather than text).

ronp 0 Posted April 16, 2013 The retailer emailed me the following specs with the N version of the camera: - It uses the Monalisa 2 whereas the M model uses the original Monalisa. - It has a DSS (Digital Slow Shutter) feature. Slow shutter speed lets you adjust the amount of light striking the sensor, and essentially determines when the video sensor sends out its batch of data for processing, REGARDLESS of image quality. - It supports accessing the OSD through the video cable using the CNB CC100 coaxial remote controller. - It has an IP67 housing vs. the M's IP66. I still don't know why it's not listed on the CNB website and rarely appears for sale on the web. Although I wanted RS-485 for accessing the menu over twisted pair because I have a cheapo RS-485 Pelco device I may consider going with the N and buying the CC100 for $50.

Kawboy12R 0 Posted April 16, 2013 Interesting feature set. I wonder if any of the remote control features are available through CNB DVRs or just that special tool? I'm using a CNB DVR for part of my household system ATM. Share this post Link to post Share on other sites
ronp 0 Posted April 18, 2013 Okay. I bit and purchased four VBN-24VFs to replace four IR bullets. I'm tired of trudging outside every night with my 24' pole with the feather duster duct taped to the end to wipe off the spiders attracted to the IR. I'm banking on the street lights providing enough light for these cameras. I also bought the CC100 to remotely access the monalink OSD - one camera requires a 32' ladder to access. I only want to do that one more time and definitely not at night! The VBN-24VFs are on clearance and are substantially less than the going online price for the VBM models. I don't want to violate forum rules so if you google "CNB Dealer" and go to the clearance page you'll see the cameras listed. You have to email sales for the price. Once I get them installed I'll post back what I think of them. I'll also have four decent 1-year-old IR bullets for sale. Share this post Link to post Share on other sites
Kawboy12R 0 Posted April 18, 2013 Thx. I'd love to see some samples, especially in tricky light. I'm on their email list for sales pricing. Share this post Link to post Share on other sites
