Hi, Can anyone recommend a networked controller that will control about 4 doors? I already have a bunch of Wiegand (Essex) Keypads. So I like the unit to work with these. I would also like to be able to control and change access codes remotely. Web interfaced preferred. Would be nice to setup schedules for codes too. Only need about 5 to 10 codes it needs to maintain tops. Not looking to spend a fortune on this. I have a webcast/cassi russo/ge already, just looking for something a bit more modern. $200 to $300? reasonable? Thanks!

In case anyone is interested, found one that meets all my needs. https://code.google.com/p/open-access-control/ http://www.accxproducts.com/content/ Still interested in hearing what else is available.

I'm curious as to why Port Forwarding seems like the default solution here. From looking through a few of the post, a number of folks use DD-WRT. DD-WRT with VPN makes it fairly easy. With VPN you will have better security. Your DVR is not subjected to attacks over the internet. Plus you'll be able to access all your DVRs (or any device) on your network without having to port forward for each device.

Is there such a tool for doing IP Cam installs? Basically a screen with Ethernet and PoE so you can plug into the camera and focus and adjust without having to plug in network some were or have the wiring in place already? Just curious. Seems like a good product to build if one does not exist. Or at least a dongle that will have PoE / Ethernet that will DHCP to the cam to view on a small laptop.

Anybody have an extra sled for a Pelco EH3512? Or know where I can pick one up? Thanks!

You might be missing the codec to view the file. I suggest trying VLC to see if it plays it first. http://www.videolan.org/vlc/ To convert you can use Handbrake http://handbrake.fr/ To Figure out what codec was used on the file use AVICodec: http://avicodec.duby.info/ All Free Software

There are DDNS clients that will do that for you. DDCLIENT for linux can be configured to detect a WAN address locally. Read it from a Router's status page or use an external web page to detect the IP. I'm not sure if any DVR vendors have done this, but it might be possible to port to a linux based DVR if they provide shell access.

You just need a video capture card for you PC. A dedicated card with Video Inputs or a USB stick would work.

Are you talking about MUNI type Mesh Networks? I'll PM you with details if so.

It could be duplicate IPs on the network. Network routing issue. Double check netmask on both devices, IPs. Any chance that when you're testing on the PC/Laptop there is more than one NIC. Wired or wireless?

Take a crossover cable to a pc and connect the other end to the DVR. Statically assign an address 192.168.1.X to the PC. Can you ping the DVR then? If not then the DVR either not configured for the right IP or the Ethernet is not working on it.

What is it that you're seeing as the problem? Which device are you seeing this at? The DVRs or the Client Computers? 192.168.2.x = Client computer, 10 Cams, 1 DVR 192.168.3.x = 10 Cams, 1 DVR What are you using as a router? Where is it placed? Have you checked the stats on the Switch to see which port is showing collisions and dropped packers?

I'm not sure what you're asking here. Fiber can carry huge amounts of bandwidth. So the simple answer would be 1 per building. If you find you need even more, there is always CWDM/DWDM to inscrease your bandwidth by using different wavelengths. Again, this only requires 1 (TX/RX) fiber pair. Of course good fiber planning is to always have spares and divergent routes.

I'm a little concerned about this. Where will the cams and nvr in your topology? Will there be cams on one side of the bridge and the nvr on the other side? The bridge will more than likely be your bottle neck in this topology.

Have you considered using power injectors for your POE devices instead? May be cheaper to get a 10/100 with PoE injectors for them than to waste a GiG port for them. Or maybe a 10/100 PoE switch with 2 GigE uplink ports? You can always add another nic to the server as you grow cameras and use 802.ad (link agg) to increase bandwidth. As for the PoE Gig switches, I believe they auto sense or is user configurable. The port can physically do Gig OR be configured for 10/100 with PoE.

Not necessarily. Let's say you have 16 cameras pushing say 12mbs (assuming HD compressed stream), that is 192mbs of data that needs to go back to the NVR. So the bottle neck it the port/nic to the server. If it was only 100mbs then you would be loosing a lot of packets.

Thanks! I plan to. How about proper termination/junction techniques?

In addition to the above questions, any thoughts on using BNC to F/RCA adapters? What is the typical loss per connector? Going the adapter route my cost per connection is still less than using BNC compression connectors. Unless I'm just on looking in the right places for them. Averaging ~$1.50 per BNC compression connector in pack of 50.

Are you trying to monitor local lan network or to and from internet? If to and from internet, then you only have one point of egress/ingress so you only need to sniff the router. For "home" based routers, going with a DD-WRT compatible router give you monitoring right in the firmware.

Can any one tell me what the proper termination technique is inside the J-box? Let's say I'm using outdoor Analog Camera's in a Camera Housing. Should I bring the COAX and Power to the camera inside the housing through the J-BOX and to destination as a home run run. Or do I pigtail from the camera to the J-Box and connect the pigtails to my home run cable inside the J-Box. If the latter, what is the proper termination technique? BNC Males from the Pigtail and the Home run cable and join with a coupler? For power and terminal connector? Thanks in advance.

Or you can just leave everything as is and get DTV converters with analog pass through.
