    Hidden Cameras

    One of the pinhole cams with the conical lens would be best, then use a large drill bit or countersink to taper the inside mounting surface in a cone to match the taper of the nose of the lens, and get it as close to the surface as possible.
  2. Foil shield cable is also more likely to pick up interference from low frequency interference (60Hz from lights/transformers/running parallel with high voltage wires, etc.) than copper braid cable. RF signals that are normally carried on foil cable are not usually affected by that type of interference, it is easily filtered in RF equipment, but baseband video (DC-15Mhz or so) will be affected.

    Bad interference in Geovision

    It's often pretty ugly, but individual wall-wart transformers for each camera is often the answer. I haven't found a DC power supply with multiple isolated outputs, like what is available for AC cameras... Anyone else found one?

    Verint 1708e to control PTZ

    On Milestone's site (pretty much the same as ONSSI as far as drivers), the PTZ support for that encoder lists Pelco P/D and JVC TKC655 Protocols as being the only ones supported. The Panasonic WVCW964 seems to only support it's own protocol, no switches to change to generic Pelco or other... You might want to check with ONSSI/Milestone to see if what you are trying to do is even possible. You might need to use something like the Panasonic WJ-NT304 4 channel encoder(s) instead. Or, use something like the Sennetech SCT-1069 Pelco RS-422 to Panasonic RS-485 converter on the data output of the Verint encoder. That would allow you to use Pelco PTZ control settings in ONSSI, and through the Verint 1708e encoder, and then convert to Panasonic protocol out to the cameras.
  6. I am not aware of anything exactly like what you are describing, although it may be out there. You might be better off with a camera like the Panasonic WV-NP502, which has a built-in image stabilization feature.
  7. A lot of NVR software is processor limited, but Exacq is really only limited by bandwidth / speed throughput to the storage location, and network bandwidth in from the cameras, and out to the clients. My personal choice for storage systems has been Direct-Attached SAS RAID6 Arrays, with the expansion bay options, you can have up to 128 drives per controller (I use the Areca 1680IX Both Exacq and Milestone have bandwidth/storage calculators on their sites, and tech support available by phone that is pretty good. Cisco would certainly be the first choice for switches, but I've used models by D-link and Netgear successfully, too. Are all 25+ cams within 100 Meters, going to go to a single switch, or will you use several switches, trunking to a central switch? If you are using multiple switches, the requirements on the edge switches are lessened, and you may only need a high-end gigabit switch at the core/headend location, and not PoE there, so something like a smaller gigabit HP Procurve switch might fit the need.

    Linksys WRT120N is not N certified!

    I've gained a lot of good information from the forum group on Ubiquiti's site, and also the WISP forum group on dslreports.com . Both have a lot of REALLY knowledgeable people on them.. and there are some very interesting debates there, too.

    Realtime or H264

    What do u call HD1 ? Are u talking about Stand alone DVR ? or ? HD1??? huh? 720X240? (I think?) I prefer between 4CIF and 16CIF+ or so, myself!

    Linksys WRT120N is not N certified!

    OOOkkkk, back on subject. Wireless "N" is a modulation scheme that allows packet aggregation into larger frames, and a more complex modulation scheme (QAM, at the higher rates), for increased throughput (theoretically, up to 600 Mbps). It can be used with one antenna, or multiple (up to four), 2.4, 5.8GHz bands, etc. Multiple "chains" (spatial streams is the proper term) allow for higher throughput, and the ability to use multipath interference to an advantage, instead of a hindrance. Overall, it's a significant advance, especially for video, because the modulation scheme actually favors multiple TCP/IP streams in the transmission (to properly test full speed throughput in "N" rate equipment, you need to have several data streams running at the same time), so it is a good development for our industry. I use quite a bit of "N" rate equipment from Ubiquiti, and the cost to performance ratio is really outstanding (imagine trying to transfer 16 analog streams with conventional analog transmitters a few years ago, just wasn't going to happen). BTW, Rory, I apologize if anything I've chimed in on was offensive to you, I personally intended nothing other than a little mild mannered ribbing over differences of opinion on particular subjects, not any personal differences. The contributions you (and a lot of others here) have made to this forum have been invaluable, and I do not want to see it all devolve over unnecessary personal attacks. I think some differences of opinion will always be there when you get a large group of people together who are passionate about what they do. That doesn't excuse personal attacks, though. On certain subjects, we just need to agree to disagree, and move on.
  11. Had a thought... On an old Camaro I had, I used some brackets that held the sparkplug wires in line like that, and they were about the same diameter as RG59, you might try some of those.

    CNB mona lisa review (sort of)

    Any chance for some sample images? The 484 has been sort of a gold standard, in my book. If this camera is close, I'll be seriously considering it for some applications.

    CNB mona lisa review (sort of)

    Yes, I also tried it welded together, same result. Try encasing the whole thing, connector and all, in clear two-part epoxy! That will make sure of an IP66 rating, at least! (also running away)
  14. Ahhh, the joys of offshore products.... Limited documentation, questionable specs, and no support. By the way, you should know that 3500mW output at 2.4 GHz is well above the legal limit allowed in most countries. Those antennas look to be about 6dBi gain, which gives you 14 Watts Effective Radiated Power, over three times the limit in the U.S., it's less in most of Europe.
  15. Biggest improvement (to me) is the option for playback through the web interface, too. The availability of the down-sampled images makes viewing through low bandwidth connection easier. Anyone worked with the active directory stuff yet? I'm looking at a large (90+) camera install using the Enterprise add-on with AD and the nested mapping.
  16. Acti has the ACD-2500 that does H.264, MPEG4, and MJPEG. Dual stream, too. If you go to Milestone's compatibility list, and select encoders, and H.264 for protocol, at the top, you will see a number of others, as well. Are you using Milestone Enterprise, or Corporate?
  17. You'll probably get a lot of different opinions here, but here's a few of my picks. Panasonic- If price isn't your top consideration, the new NP/NW502 series cams are outstanding. CCD imager for lower light capability, 1.3 MP in H.264, 3.0 MP in MJPEG, foolproof design for weatherproofing, easy installation. Acti- I use quite a bit of it, good price point, decent performance, good reliability. Acti is trying to position themselves as the Honda of the IP camera market, and seem to be succeeding. Pelco- used some of their first generation IP product, less than impressive. Seem to be having a lot of quality control and supply issues recently. Vivotek- I have had serious reliability issues with them, although it's been a while, their new stuff could be better? BTW, the newest Milestone drivers for Arecont use Arecont's SDK plug-in, rather than their own driver, seems to have helped some problems. Arecont has been decent for us, not as reliable as some, but getting better. I would try to use Auto-Iris models if possible, Fujinon and Tamron are finally coming out with decent Auto-Iris lenses for megapixel, and you really need it for low light on a CMOS imager. Stardot- Haven't tried it yet, well reviewed, could be a competitive replacement for Arecont for us. Planning on trying some soon. Sanyo- Used the VCC-HD4000, working very well, the built-in zoom lens and autofocus is a great feature, planning on trying their new PTZ's soon.
  18. You do not have to go analog cameras in the elevators, you can use a DSL-type converter to transmit Ethernet over the elevator traveler cable, I've had good luck with these http://netsys-direct.com/proddetail.php?prod=NH-300SEKIT for a single cam they'll work fine, or they have higher data rate models available, too. As far as the Vivotek, I have had significant reliability problems with them, Acti has been far more reliable, for me.
  19. Sorry, it's been a while since I used the Genex multiplexers, I was thinking it had the RS422 out, when it does not. You can convert the Coaxitron output to RS422 with these, though... http://www.sennetech.net/Manuals/SCT_CRX/sct-crx-pelco-pelco.pdf or this http://www.bolideco.com/PDF/CCTV%20System/DR-AD300.pdf

    What is Pelco doing?!?

    Just tried to order some Pelco EH3512 housings (the most common housing on earth, I think?) and found out they are back ordered until March 23rd. !?! WTF? I was in their warehouse recently, the have DX8000 DVR's (who wants them?) stacked to the ceiling.. but none of their most commonly ordered product! I've run into that with Spectra's, and IS090 / 110 series cams, as well. Anybody know who might be stocking a few, or what somebody at Pelco's planning department is smoking?

    Newby asks for help with Pelco camera and dvr

    You might want to check with Pelco on the Spectra compatibility, I think you can put a newer dome drive in an older backbox, but not the other way around, because the older backboxes have a cooling fan in them, newer ones the fan is in the dome drive....
  22. You have a couple of choices.. Get a used Pelco Multiplexer to connect the KBD4000 to, and get your RS422 or Coaxitron output from it, or, (and this is a little trickier) the KBD4000 and KBD300 are the exact same chassis, just a different programming chip (easily changed, in a socket on the board) and overlay decal. If you can get the chip and decal (sorry, don't have the exact part#'s handy) from Pelco, you can change one into the other.

    PTZ PC control and adaptor

    I knew there was something else out there I had tried before, just found it again... http://www.commfront.com/RS232_Examples/CCTV/Pelco_D_Pelco_P_Examples_Tutorial.HTM#0 That, with EventGhost, and a USB-RS422 adapter, should do the job.

    PTZ PC control and adaptor

    In your other post, you referenced wanting to use a USB joystick, you should be able to use the software Soundy referenced, along with this... http://www.eventghost.org/ It's a very useful event handling/scripting Python application, you should be able to link joystick actions to the keyboard shortcuts with it.

    HD PTZ Camera

    Been kicking that idea around, too, the HD4000 is a pretty nice cam. If you come up with anything, let us know... The one I listed above (VCC-HD4600) looks pretty good, though.
