    How to view Geovision connected cameras on TV ?

    It's really expensive from that site. That site was the first google result. The RF modulator is very decent. Cheap Modulators pretty much suck. This one is 4 channels, stereo, IR repeaters, programmable to most CATV channels. FUnny thing is you can't use something like channel 95 through 99 for some reason. I'm using 72,74,76,78.

    How to view Geovision connected cameras on TV ?

    This is my Intermediate Distribution Facility (IDF) The top 24 port Patch Panel actually serves up data cables to TV outlet locations. I can patch through a modem line for TIVO, cable boxes, satellite receivers, whatever. And of course I could patch through Ethernet, Line Level ins/outs, Or even IR emitters for whole house remote control. 3 of the data cables are feeders back to the Main Distribution Facility (MDF) that is on a back board in a closet that that is now full. 4 ft. swingout wall mount rack. I mounted the rack high enough to add a 3 footer swingout right below it. Typical TV outlet 3 cat5e data (blue jacks) and 2 RG6QS coaxial cables Well, this isn't really typical because this is actually the only TV hanging on a wall. It's in the office. The RF panel supplys 2 RG6QS to each of 5 TV locations. And so far I have 4 RG59 Siamese cables terminated to this panel for CCTV. 2 cameras patch through to the RF modulator that is kind of difficult to see. (Hanging off the right side of rack in the lower right side of picture) Then the cables being used (and the Modulator output) are patched into the 3X8 distribution panel hanging off the left side of the rack in the lower left of the picture. You can just see the tip of the antenna on a wireless linksys router in the middle of the rack picture. I don't use the routers' wireless. I have a much better outdoor AP I use. This shelf has modems, 2 routers and a little switch. Below that is another shelf that supports my notebook computer very nicely. But I will have to lower the upper shelf soon when I start phase II. Whole house audio.

    How to view Geovision connected cameras on TV ?

    I agree. I am using a modified version of this senerio. My girlfriend loves it. When someone rings the doorbell she turns the TV to channel 76 to see who's there. Then if she wants she can intercom the door and have a conversation with them. I am feeding the camera into a 4 channel RF modulator http://www.smarthome.com/7704cm.html then into a 3X8 Distribution panel http://www.smarthome.com/7712.html To feed 5 TV's throughout the house. I also feed the VCR/DVD player into the modulator. Maybe you could use something like this if you have a video output on your PC's video card? I'd post a picture of all this rack mounted stuff if I had somewhere it host the picture...
  4. That's disappointing to hear. I have never had a failure with the F conns. But really, with the exposed center conductor it's pretty easy to know it's all good before you compress the fitting. The closest I can find to instructions for the RCA's was this: http://www.tselectronic.com/thomandbetts/sns1p6rmx.html That's what the F conns need. and it's the same instructions they give on the BNC page. But obviously there is more to it then that if you are having failures.
  5. I would try it just like the F conns. ? Because unless you have to use a different stripper I don't see how it could be much different.

    Wiring Lengths

    I am relatively proficient with optical fiber installations. What kind of media converters are being used for CCTV over fiber?
  7. Yes. SnS make a weather tight connection. But I picked it up at the suggestion of a guy I know that works for the cable company. I figured if it was good enough for them, it was good enough for me. Since then they have switched to Digicon. D'oh! I like the professional look of the compression fittings.
  8. I haven't tried with my tool. but the F connectors are a tight fit. I am pretty sure there is no way a BNC will fit in there. I can't tell how that tool you linked to works. I was thinking of picking up something like this:

    Phone System

    I have some electricians around here that pull data cabling. They pretty much get it done. But the design isn't to the level of what I can do and they just don't make it look nice. And the networks technically aren't up to spec. No test certifications for one. Some electricians in the larger city 60 miles South of me know what they are doing though. I was actually 2+ years into an electrician apprenticeship in the mid 90's. Then the dot com thing took off and working in "Telecom Valley" opened up an opportunity I didn't want to pass up.

    Phone System

    Sounds like you guys have some different systems to play with over there. Over here all I have ever seen for a small KXTD was the 308. It comes 308 with no expansion options. ISDN? Not too much, but I do work with HiCap circuits Like T's and xDSL as they pertain to interfacing with Local Area Networks. Mostly at the physical layer. i.e. I'm a cable puller Besides cabling a lot of my work is as a subcontractor for National companies that dispatch service calls to large chain stores. I get dispatched to service anything from phones, PA's, network issues, and so on.
  11. I really like SnS. My compression tool doesn't work with the BNC's. Which tool are you using?

    Phone System

    Did you mean 308? or do you guys have a 208? I'm using the 308 here at the house. with the TVS50 voicemail. I have worked on the 624's. Those being analog need both pairs. I wasn't really paying attention to ozzy's show. But I heard the phone ringing and knew right away it was a panasonic I looked up just in time to see him answering a KX-T7436. (the big 6 line display!) I was suprized to see white phones. Black desksets are way more popular around here. I haven't done anywork with VoIP. I guess I better get upto speed with the technology.
  13. Knob and Tube is still ok if it is in good shape and you don't need a ground. I still have some lighting circuits running on Knob and Tube in my house. And that brings me to my point. I am too new to CCTV to comment on video interference. But I run a lot of voice and data cabling. And the probability of interference has a lot to do on what the circuit is powering. A lighting circuit isn't going to interfere nearly as much as a circuit powering an arc welder. You are on the right track though. keep your low voltage signaling circuits running perpendicular to the high voltage stuff.

    UTP & BNC Enclosure

    Yeah, Split loom is good stuff. I like the Spiral Wrap stuff too. But if you will have a bend then the Split Loom will probably cover the cables better. I feel the Spiral Wrap is better for pysical portection of the cables. It's thicker and doesn't seem as susceptible to being crushed.

    cable/wire labler?

    I use the PT-65 everyday. I like it. I was disappointed that I had to buy a PT-1180 during one job because the PT-65 didn't have clear tape available. I'd say these are fine for faceplates. But not the best option for cable labels. But they work ok on cables if "label flags" will work for you. The next cabling job I do that has more the 48 cables will give me the excuse I am looking for to buy the new PT-1650. It's a true datacom/telecom labeler. http://www.advizia.com/brother/modelDetail.asp?PkgID=382258&User=ptouch&Rnd=360 If I was looking for the next step in mass label making I would be looking at the Brady TLS 2200. http://www.bradyid.com/web/SiteBuilder/BradyiISBv1r0.nsf/FLV/TLS2200

    Phone System

    I have seen telephone systems use anything from 25 pairs (75 for the receptionist phone!) down to 1 pair. But generally 1 or 2 pairs for modern systems. But be forwarned, I still run into a lot of old AT&T systems that use 4 pairs. Hey CCTVINSTALLER, I love those Panasonic systems. I even have the KXTD with the TVS voicemail in my house. And it's the same system in Ozzy Osbourne's house! It does indeed take 2 pairs for full functionality. But as you probably know; in a pinch you can get away with 1 pair if you don't need the eXtra Device Port (XDP). So the center pair is actually for plugging in a single line phone like a cordless phone, or an answering machine. The digital pair needed for the system phone is the second pair.

    Network Cable

    A Cat5 rated 66 block would probably be better. But what kind of cable are you using within the building? Remember you can't terminate stranded wire to a punchdown block. If you are simply leaving the network guys a loose Cat5 cable just for them then the other services: Phone, alarm, CCTV will probably do just fine on terminal strips. Didn't I read somewhere the camera baluns can even use Cat3 cable? Cat 3 is way more tolerent then Cat5.

    Network Cable

    Yes two pairs. And I would specifically use the orange and green pair from the same cable. The orange and green pairs twist rate was probably optimized to carry the send and receive signals. But it looks to me you could put the Ethernet on it's own cable and still have your extra pair for the monitor. Then in the future if you need pairs you can worry about affecting the network connection. Becuase the barrier strips could degrade the signal substantially. Be prepared. You may have to settle on 10Mbps. Have you settled on which services you are going to share with which cables?

    Security for football pitch.. NEED HELP!

    All I can really comment on is the UTP vs. STP. I say stick with UTP. Check this out:

    Network Cable

    CCTVINSTALLER is absolutely right. The one thing I would add about the crossover cable that may not be obvious to those who don't work with Cat5/6 cabling much is: you only switch ONE side. So... 1= white/green, 2=green, 3=white/orange, 6=orange on one end and 1= white/orange, 2=orange, 3=white/green, 6=green on the other. If you switch both ends then you are back to a straight through cable Rory, Cat5 as you probably know is short for Category 5. It is a wide scope standard that specifies a lot more then just cable properties. It outlines (among other things) proper installation techniques like maximum bend radius, max. pulling tension, cable support structures, Cable testing standards (I use a 9 thousand dollar cable certifier) and so on right down to labeling faceplates. If you don’t follow any one of the “Standardâ€
  21. Is that card from a distributor? or like ebay? That's a killer price from what I've seen. I would be interested if anyone knows of any Geo Distributors selling at this price...

    Linsys routers

    I'm not sure. Sounds like you guys do it different then we do. My options are Obtain IP automatically Static IP PPPOE RAS PPTP Heart Beat Signal Of course the ISP would know. But if you are just playing around with it I would try the bridged modes first. I think routed would be something you requested and typically comes with a block of IPs.

    Linsys routers

    That's a good question. But I think if you were given a static IP you don't need PPPoE or PPPoA.

    Linsys routers

    One thing I noticed is the BEFW11S4 is 802.11b compliant (11Mbps for wireless) and the WAG54G is 802.11g compliant (54Mbps wireless) And it looks like the WAG54G might actually have an ADSL modem built in? I wonder if that is an added feature or if they took away the WAN port in favor of the ADSL modem?
