similar to: Grandstream surveillance devices

I heard about some inexpensive security cameras which get their power through the same cat5 cable which delivers the data/pictures (which would simplify wiring tremendously). Does anyone know about these? Do they work with Linux, particularly CentOS? tnx 4 tips.

Hi, folks, I'm still trying to find a video capture card that won't crash Dell servers, and ran across a Blackmagic BDLKDUO2 DeckLink Duo 2. It claims to support Linux. I'm also seeing, in the few non-Blabkmagic or sales pages I can find, that they like "binary blobs". I also haven't been able to find anything about o/s or library requirements. Has anyone run

I suggested to our Homeowners Association that we begin a Private Forum (phpBB) and web site. That suggestion has been well received and we will proceed with that. Now, I have become involved in a much more complex and important project, which is Video Surveillance, for the entrance to our subdivision. I Googled and found two (2) things for Linux that seem to be OK: (a) ZoneMinder

Does anyone know of a DVR that runs Linux that does NOT USE Active-X, and/or allows logging in directly? All I keep running into are crap that ->requires<- IE, and don't allow directly logging in. mark

Has anyone used either the 8 port or 4 port FXO device from Grandstream? (GXW-4108 or 4104). They seem to be the lowest cost multi port FXO devices that I can find, so I'm getting ready to buy the 8 port version. I just want to see if there are any opinions on the device before I commit to the purchase. If people have not used the Grandstream, are there any issues with using

With the continuing annoyance from motion, my manager's asked me to go looking again for a video surveillance appliance: basically, a motion-detecting DVR and cameras. The big thing, of course, is a) price (this is a US federal gov't agency, and being civilian, money is *tight*, don't give me the libertarian/GOP line about how freely we spend, thankyouverymuch), b) it has to be on the

In a few weeks, no SIP call is going to terminate unless they are signed properly, as mandated by law. We are in the business of Stir-Shaken, signing calls, as an FCC-approved provider. A big differentiator between our service and the rest: we are the only ones who don't need to receive the calls in our servers to sign them. We do this over a MySQL call, easily connectable to Asterisk via

If I use a call file (/var/spool/asterisk/outgoing) is it possible to have a video phone connect to a camera (linksys wvc200) and show the camera stream and hear the audio? How would I do that? Jerry

Hello, I am interested in using Morans I for different time intervals to detect disease clusters. Ultimately I would like to use CUSUM - or similar monitoring statistic to monitor the results of Morans I - similar to the work by Rogerson (2005) Spatial Surveillance and Cummulative Sum Methods in Spatial and Syndromic Surveillance for Public Health. Thus far - thanks to the list I have

Hello, At one of our locations, we have started to see Polycom 501s (running 1.6.7 firmware) randomly reboot. We have taken packet traces of the phones to determine if there is something odd in the Layer 2 or 3 of the network that might cause it, and have not seen anything strange. There are no errors on the ports. This appears to be affecting POE powered as well as AC powered phones. The Polycom

Hello all, We have an Asterisk server that has worked without issue for a while. Before, only Sipura and Polycom 500 series phones were used. Recently, we've added a few POE switches and 20 or so Polycom 330's. The 330's seem to lock up often. One easy way to do this is by hitting the * key. I looked thru the XML files for dialplan and what not, nothing stood out.

How do you guys like the 330 and 320? I've been looking at this as my "standard" phone, since it's relatively cheaper than the 501 which is the phone I currently push with my PBX systems. Most of my customers do not use more than one line per phone, so having 3 lines on the 501 is not necessarily useful. Also, I read that the phone offers TLS security. What does that mean?

Hi I want to put up a few cameras connected to a CentOS box. I currently have a box with one camera and that works (USB), I can take a pic (the script does that) and see that on a webpage. However, I want to have a couple of cameras a little further away (more than 5 meters). USB has a limit, I have tried that camera with a longer cable and it does not work ... so I need to route that in a

Hi Could anybody please advice me to work with wecamera in Rails. What i want to do is to capture webcam images from a machine and send that data to a remote server there it needs to be processed. I have no idea of where to start.Please help Thanks in advance Sijo -- Posted via http://www.ruby-forum.com/.

I have 3 phones P1 is a non video phone - grandstream P2 is a Grandstream GXV3000 P3 is a Grandstream GXV3000 Using P1 to place a call to P2 I get audio only (as expected). Then on P1 I transfer the call to P3 and I still only get audio. At this point shouldn't the two video phones P2 and P3 say to each other we are video and so startup the video stream??? This is not working at this time?

What would your wish list be for a handheld theora video camera? 640x480 25fps/30fps 320x240 25fps/30fps Record to a memory card (SD) Lan / WIFI support (auto/manual upload of file on memory card) Live streaming (icecast like) Videoconferencing support Voip (sip) speex audio I am bouncing the idea around of developing a handheld video camera designed for mobile video streaming Win a

Dear all, Just wanted to know if any one had deployed the Grandstream GXW 4024 yet. Wanted to hear any feedback and/or problems with this unit that you may have experienced. Thank you. -- Faraz R Khan Chief Architect Emergen Consulting Pvt Ltd www.emergen.biz
