I have an IP camera and my broadband access has a dynamic IP. What you do is firstly give your IP Camera an private IP address in one of these ranges: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255 Next, get a router/firewall with Dynamic DNS Support and which you can use Port Forwarding.. I use a Netgear FVL328 (there are cheaper ones with same functions). It supports DynDNS.org, TZO.com & ngDDNS dynamic DNS services. We have signed up for a free account with DynDNS.org, when you do this you get a domain name like what-you-choose.homedns.org which you can then use to access your camera... Now, when the router detects a change in the IP address it will automatically connect to DynDNS.org and update the IP address; therefore typing http://what-you-choose.homedns.org in your browser for example will resolve to the new IP address and connect to your camera..... If you have more than one camera, put each on a different port - for example 8080, 8081 and so on, then you can access each individual camera using a URL like http://what-you-choose.homedns.org:8080 http://what-you-choose.homedns.org:8081 and so on; however for this to work you also need to setup Port Forwarding within the router, for example if your two cameras were setup with private IP addresses of: 10.0.0.1 (and set for port 8080) 10.0.0.2 (and set for port 8081) you would configure your router to forward all requests on port 8080 to 10.0.0.1 and requests on port 8081 to 10.0.0.2 If you have a DVR on the same network, i.e. not traversing the internet, you would just set up access using the cameras private ip address, and perhaps port... bit rushed that but should make sense...

I'd be looking at the PSU, especially if I had another to throw in and test, maybe somethings wrong and it cant supply the full 500W or whatever is needed.... Some of the P4 chips are 100W+ on their own, is there a P4 cpu that only takes 20-50W?? Just because the right voltages are present does not mean its capable of pushing out the rated Watts... Another option is to grab a cheap POST Card off Ebay; if you dont know what one of these is then its a small cct board usually with 2 edge connectors, one for an ISA slot, the other for a PCI slot. During a PC POST (Power On Self Test) the BIOS sends a code to the ISA/PCI bus for each test it is doing, this code is displayed on LEDs on the POST Card. By cross referencing the last code before the PC stops against the BIOS documentation you can, a lot of the time - not always, get a pretty good clue as to whats wrong with your PC. These cards are also ideal for those PCs that seem dead because they stop before they put anything on your VDU.. Can I be classed as a computer nerd now? I've been called so much worse so many times, PC Nerd kind of sounds nice today MrMcauber

Start > Control Panel Double Click Network Connections... Right Click the Connection you want the IP for, Select "Status" then click the "Support" tab.... Should give you all you need... MrMcauber

Is it a Tag number? so your first camera would be FF-01-00-EL.L your second FF-02-00-EL.L and so on? Not like the normal tag numbers I see on drawings, but similar...

Should be fine, both 75Ohm cables, RG59 much more lossy than CT100 so if anything, CT100 should be better. I think losses on RG59 over 100m is about 12db, CT100 is about 6.5db (thats at 100Mhz) if memory serves me right. Costs of these cables at RS Components is about the same too, CT100 slightly more expensive. CT100 is low loss and used for drop feeds from LNB of a satellite dish to a satellite digital TV receiver, such as Sky TV in the UK. RS info says suitable for Video/CCTV use too.

Hi, this thread has prompted my joining the forum and an immediate firt post, basically because I have worked on CCTV (amongst many other things) in the petrochemical industry for around 16 years. Theres a lot of good information above, but not all 100% accurate. Firstly, I dont like the phrase, Explosion Proof. As already explained (kind of) equipment (any electrical equipment) used in a "hazardous" area needs to be fitted in a correctly certified ensclosure. Invariably the enclosure will prevent any flame inside an enclosure from travelling outside and igniting the surrounding atmosphere. There are various types of protection such as Exe (Increased Safety), Exd (Flameproof) and so on - quite a few more. However, hazardous areas in the petrochemical industry are usually "Zoned", Zone0 - Explosive atmosphere continiously present for long periods, Zone1 - Where explosive gas/air mixture is likely to occur during normal operations and Zone2 - Gas/Air mixture less likely to occur and only for short periods. Other areas like inside pressurised accomodation may not be zoned and can use any equipment. You can only use certain protection in some areas, so Zone0 MUST be ia (Instrinsically Safe) or Exs (Special apparatus certified for zone 0)...ONLY Zone1 - Anything from Zone0 + Exd, Exib, Exp, Exe, Exs - ONLY Zone2 - Anything from above plus - Exn, ExO and Exq - ONLY So you need to know the zone classification for the equipment being installed, though most kit is installed assuming Zone 1 unless you are sepcifically told it is zone0 Getting a certified box/enclosure is one thing, but you must be aware of how much free space you are allowed to leave inside, then you must use correctly certified glands for cable entries into the enclosure - so an Exd enclosure must use Exd certified glands! Cables are usually armoured, they must be correctly glanded to stop them blowing out if an explosion occurs inside the box.... Anyway, you get the picture, there is a lot to using electrical equipment in hazardous areas. The offshore industry as far as I am aware will not let you fit this kit unless you have been on an Eex course - think Abtex in Aberdeen do them amongst others - just getting an Exd box and stuffing a camera in with armoured cable is not enough! I believe this lot applies to other industries too, such as mining (which I believe brought about the Ex rating system via cenelec??), and explosive atmospheres does not just mean gas either, dust filled areas can be explosive too. Oh, yeah - then you got to get the IP rating of the equipment right, you need to know what kind of gasses may be present so that you can get your Gas Grouping and Temperature Classification right on your equipment certification. Use a piece of T1 temnperature rated equipment where Ethylene is present and you have a problem!! Seriously, if your getting into hazardous area equipment - do the course! It may have changed slightly since I did it since ATEX came along, but not by much. If anyone wants any more information, then direct mail me at: Gary dot walker@ntlworld.com Just out of interest, Coex seem to be the biggest petrochemical cctv company I have encountered, http://www.coex.ltd.uk/ Oh, and this is based on my experience in the UK/Europe - other countries regions may have different regulations.
