you can set motion detection recording for the megapixel stream locally to an sd card (if its supported of course) , and continously record the analog video from the camera's composite output.

Thank you hardwired! You mention rfarmor for shielding but can the ubiquiti titanium series be used for the same purpose? Other question im uncertain about is that where can i use point to multipoint links 'safely'? For example at headstation I* (cam4 & cam5). Using a 90deg(horiz bw)/4deg(vert bw) 20dBi sector antenna is sufficient for pick up the two cameras or its better to go with PtP connection? *I have attached a little draft about this scene, i know beamwiths are not this perfect straight its really just for demonstrate my problem. Is it recommended to put rocketM at the headstation tower where im going to use PtMP connections and nanostation M5 at the cameras side(stations)? If we have to install for example 4-5 antennas (PtP) on a tower, for what should we pay attention? Channel distribution, the mentioned isolation with custom shielding, maybe rocketM ap's with GPS function and vertical separation. Anything else needs to be care of? Or better to use nanoBridges? Your help is greatly appreciated, thank you hardwired.

Hello! The main target is to monitor 15pcs 2megapixel cameras at two central locations ('PH', 'R' in the attached pdf). There is a wired backbone with 3 headstation (I,II,III) as you can see on the attached plan. The headstations and the monitoring centers are sharing this 10Gbit wired connection. The 15pcs IP cameras needs to be connected to the backbone throught the headstations, using wireless (5Ghz) connections. We have built some wireless systems before, but only 4-5ip cams and small distances (50-100m). Have lots of experience with structured networks and with IP networks in general. But this one is different because the long distances and the count of the IP cameras. We are counting with approx 100Mbit bandwith take with the 15pcs ip camera (5Mbit/sec per camera), thats not a problem i think. For split screen monitoring the cameras we will use CIF secondary streams, 2mpix streams will be used only for selected/full screen camera monitoring. Please any recommendations on choosing the right APs and antennas? Was working with nanostaion M5 APs before, but never used anything other then the built in sector antennas (only small distances). Some help would be greatly appreciated. My opinion on the APs/Antennas: Headstation I (cam1,2,4,5) For cam1/2: Rocket M5 with 90deg 20dBi sector antenna? For cam4/5: Same AP and antenna? But maybe the 4deg. elevation beamwidth wont be enough so we should use two point-to-point link for this two camera? One Point-to-Point link for camera 3? Headstation II (cam6,7,8,15) Lots of differences here on the distances, so we need four pcs AP/sector-antenna pairs (four Point to Point link)? Should we use Rocket M5 with GPS function? I read that its recommended with more than two APs on one tower because of interference, even with using different channels. (gps function - TX synchronize) Headstation III (cam9,10,11,12,13,14) cam10,14 : AP + 90deg. sector antenna cam11,12,13 : three point-to-point link? cam9 : nanostation M5 with built-in sector antenna? (one point-to-point link) What Access points to use at the station (ip camera) side? Line of sight is no problem, the terrain is totally flat. Keeping fresnel zones in mind (towers etc), but what device to use for to check the scenes for interferences? Any help would be greatly appreciated!

Some customer wants to record and monitor approx 25-26 2megapixel (h.264) cameras but i just cant esteem the parameters of the pc that can handle this... Ok, lets say we need a dual or quad core xeon (well another question is that can the software support more than one core? Hell knows...) and maybe i can reduce the fps to 12 or to 6 in the worst scenario... but then again... is there any server pc config that can handle 25piece of 2mpixel h.264 stream? And what video card can render this? Another thing is the switch. Thats ok that it should have a gigabit port and the maximum broadband the cameras will take is 'only' 60-70mbit (max. 2-3mbit/cam)... but im not sure that every cheap gigabit switch is able to manage the constant traffic of the 26 2mpixel cameras... Thank You very much in advance for your help/hint! Best regards.

Thank You very much People, You helped a lot. The cameras and the software are from axview, and lets say 12 fps/cam is enough. We told the customer that maybe its enough to install 2mpixel cameras at the most crucial places, but he wants them at every location... At some point we should step over the 100m eth segment limit, maybe will using eth extenders.

Hello, we installed a lot of cctv systems but never used wireless before. I mean i know 802.11 but this is a different story. (: I have found motorola canopy (sorry but cant link yet) and it seems a fairly good solution, 'only' problem is found the correct devices we should use for this project. (I attached a small draft of the system.) I should take access points per camera (which ones?), a cluster management module (how many etc?) if im right, but what other devices are necessary for this distances? Whats if there is no direct line of sight? As You see the most far distance is about 3.5km (2.18 miles). It should be a 5Ghz system. Any help would be greatly appreciated![/b]

Thank You all for enlightening me.

Hello, i just got a ptz controller you can see on the picture but it has some very old standard connectors. One 5 pole DIN for iris, zoom and focus and an other one with 6pin for the directions. So my question is that are there any speed domes with these connectors? Can someone please show me one? Most of the dvrs and speed domes i saw has RS485. Is there a converter or something for this? For what cameras can i use this controller? I just dont know where to connect these wires... Thank You! (& sorry for the errors, im not a native english speaker)
