  1. If the fiber suffered damage or macrobending, there may be higher losses at the control wavelength than the video transmission wavelength (that unit is listed at 1310/1550nm operation, not sure which is the control and which is the video), so, theoretically, you could lose control but not the video. Also possible that the operation is right on the edge of operation, and the transmitter/receiver pair for the control is slightly weaker than the pair for video. Is the fiber directly terminated at the devices, or are there jumpers? Try changing jumpers, if applicable. Either way, an OTDR check would tell you for sure. BTW, I usually try "Swearing at it profusely" earlier in the process.....
  2. Note, there are differences in the "M" line, you get wireless "N" datarates, and 2x2 MIMO (in the NSM and some other models, some are 1x1 MIMO)- Working with the Picostations should help you gain some familiarity, though. I would use a NSM5 at #3,#4 aimed at one of two NSM5's at #2 location, and the other at #2, and#1 aimed to the last NSM5 at the home base location. Run #4, #3, and one unit at #2 on one channel, the other at location #2, #1, and Home Base on another. Just make sure whatever you use is compatible with the Avermedia S/W, not too familiar with it. You should have plenty of bandwidth to spare, total link throughput should be in the 60-70Mbps range, standard res cameras/encoders will probably not be much more than 1.5-2Mbps each. At those distances, make sure you turn down the output power, you should adjust to have a signal level at around -50 or so.
  3. I use Ubiquiti equipment frequently in my installations, and have had good results. A few hints: Use equipment in WDS-Ap to WDS-Station mode, to avoid MAC translation, which can affect some NVR setups. Do not use WDS repeating, that reduces your bandwidth by half at each hop. Order your equipment well in advance: Ubiquiti is prone to supply shortages.. Although that does tell you how in demand their products are! Be courteous: Talk to any local wireless ISP's in your area, and ask them to coordinate channel usage with you. You'll both benefit. Buy a few NSM5's in advance, and try them out. Take a look at some Wiki items here http://www.ubnt.com/wiki/AirMax_Products, as well as their forum, very little documentation comes with the units themselves (default IP and password is all). The PoE that Ubiquiti equipment uses is NOT standard 802.3af, it's a proprietary lower voltage. If you want to power the Ubiquiti equipment using standard PoE switches, there is an adapter available here http://www.ubnt.com/8023af It sound like you also are trying to distribute Internet connectivity to the hangers/homes at 2.4GHz, is that the case? Can you provide aerial maps, etc, showing the distances and locations of what you are trying to accomplish? That can help greatly in the system layout.
  4. You could use a barcode reader with a RS-232 output, and this converter from Cypress, http://www.cypresscomputer.com/product_details.htm?product=CVX-1300 to convert to Wiegand. *************Edit********** Just remembered this one, http://www.galaxysys.com/index.php?tpl=readers/barcode/barcode
  5. Most likely, Milestone is not cropping the image, it's just formatting it to fit the window aspect ratio. Try unchecking the setting "Maintain image aspect ratio" in the setup of the smart client software.
  6. One of my sites is displaying 37 cameras (although a mix of megapixel and standard resolution) just fine, using the resolution settings I described earlier.

    Is this even possible?

    Well, hopefully you are going to be able to get to a doctor or clinic? I've seen some of your previous horror stories of the state of medical facilities there!

    And, of course, none of this is actually pertinent, considering we're all just actually waiting to see what kind of miracle product our friend here will soon be offering us...

    Well, I hope you are feeling better soon, and are able to get some adequate treatment for it there. (I'm assuming you've been Googling the heck out of treatment options )
  10. I'd suggest giving Milestone a try, the "Go" version is free, although some of the "Smart Search" features are limited compared to their upper line version, it still has thumbnail and a scrub bar search that works pretty nicely. Exacq is another option, but I have seen some hiccups in connectivity with Sanyo cameras similar to what you described the Nuuo software. Milestone seems to work better with the Sanyo cameras, in my experience. I've been able to run them in H.264 or MJPEG, all resolutions work fine (you do need to set the stream resolution in the camera first, though).

    Probably is a small break, or something like that, but if you're going to the doctor anyway, you might want to ask about gout as a possibility.....
  13. Yes. It significantly reduces processing load, and bandwidth necessary for a decent framerate, and the difference is not very noticeable, especially in smaller multiple windows. Yes' date=' it goes to full resolution, unless you select otherwise (and, it is adjustable for full-screen and split screen on a per-camera, per-view, and per-user basis). 72 in a 16X9 format, 100 in 4X3 format (same in live or playback-although multiple monitors are supported, as well.) BTW, I just tried that out, those are pretty small squares, even on a 1080p 42" monitor!
  14. You're welcome, glad that helped. You can also create multiple viewing profiles. Running at that image quality setting, or lower, will also help greatly with viewing remotely over low bandwidth WAN connections, or to laptops, etc. with limited video processing capability. Also, you did not mention what video card your unit had, or was it on-board video? Most VMS software packages function better with a separate, reasonable quality video card.
  15. It does seem that most IP cameras run somewhat hotter than conventional analog ones. We are in a very hot area (summers at 110F+), and have not seen any significant problems with them, though. As far as a recording software, there is a free, limited version of Milestone software called "Go" on their website(8 channel, five day recording), or "Essential" at $99.00 MSRP for two channel base license+ $50 Each additional channel, and Exacq will run one channel in a demo mode.

    Need advise on security of network CCTV

    The most straightforward approach for high security might be to setup access through VPN on a router configured with it (I have set up access to my home this way, through a Netgear router running DD-WRT), plus DDNS resolution, if necessary (Dynamic IP from ISP). The original poster needs to let us know more about the DVR he is using, and we can offer more suggestions from that point.
  17. Yes, the Sanyo can only have the lens controlled from another controller, a better choice would be an IP camera that has outputs to control a pan/tilt mechanism. That would allow control and viewing through one IP address/GUI interface. Acti has something similar in their new 4 Megapixel line, article here http://www.acti.com/pantilt . I would imagine a few other camera manufacturers have something similar.
  18. ... And, can cause actual pain. If you try and drill out the inner sled to clear a standard conduit fitting with a Unibit, the sled will spin around, and lacerate your index finger, pinning it against the trigger in the process... Not me, by the way, but one of our installers!

    Outdoor NVR enclosure

    I've put some self-built NVR's outside here in Fresno, CA, and had them work, but I wouldn't recommend it for the long term. Take a look at DSL point to point extenders from Planet or Netsys-direct (they'll even work on a active phone line, if you only have one pair to the gate available). Then put the cameras, one end of the DSL link, and a small PoE switch at the gate, and get the NVR and the other end of the DSL link inside, if you can. ********Edit******** Heat problems in Pleasanton? HA!!... You know what Fresno is like, don't you
  20. See setting under "Image Quality" in the smart client, here. Running on the server at this setting only adds about 35% CPU load. Server is a Win7, I5, GeForce 9500 machine. Cameras are all set at 2MP, H.264, 10-15FPS.
  21. Pelco EH2508, 6.25" L x 2.75" W x 2.75" H., with EM1450 mounting arm. Bit of a pain to work with, though. Focus and adjust the camera before putting it in the tube, there's no room to do it after.
  22. Make sure the viewing side is properly terminated with a 75 Ohm load, a signal level that is too high can cause this (voltage peaks in the video waveform are higher with brighter images).
  23. Interesting... I've pulled a couple of 2TB WD Greens out of a RAID that threw errors saying the drives were failing... replaced them with Blacks... still have the Greens sitting on a shelf. I should test them... hmmmmm! The reason the drives show as failed in a RAID array, especially true hardware RAID, is that the green drives, (and some other desktop drives, too), are designed to spin down after a period of non-use, which happens often in a RAID array. If the drive doesn't spin up fast enough when needed, the controller marks it as failed. Check the event log of a system using green drives like that, you'll see lots of drive lost/drive reappearing messages. The other problem with some green/desktop drives is the lack of TLER (Time Limited Error Recovery), which means if a regular drive finds an error, it will spend too much time trying to fix itself, and the controller will mark it as failed. RAID-specific drives limit the amount of time they spend trying to fix themselves, counting on the controller to find and fix errors instead.
  24. The Sanyo VCP-L07W1 is listed as a .7x wide angle adapter for the VCC-HD4600, that might get you wide enough.
