 |
|
Can you connect a network camera (built-in server/IP) directly to an
ADSL modem with NO router if you don't need a PC on the LAN
simultaneously? Diagrams for network cams seem to assume you'll always
have a PC hooked up with a wired/wireless router in the loop.
In this case, the camera cable would _replace_ the PC's cable in the
modem slot - for monitoring a vacant house. When people return, the
camera would be unplugged and replaced by the PC again. Logic tells me
a separate router is NOT needed for a simple swap-out like that.
The camera model hasn't been decided yet, but I am leaning toward the
Panasonic BL-XX or BB-XX series (< $200). I'm also wondering if these
devices can be set up without the PC and camera being online at the
same time. Thanks.

Two things: |
The modem would have to have an Ethernet connection and not just a USB.
The other thing is that the router usually contains your ISP connection
information. Usually when PCs are connected to a router, the PC(s)
contain NO information on the Internet connection. We have four
computers hooked to our router at home and if you went through them you
would find that not one of them have an Internet connection on them as
the LAN connects to the Internet via the router. So unless you can store
your ISPs info in the modem, then I would have to say that the answer is
no. However, I stand to be corrected if I am wrong! :-) |

This is an ADSL modem so it's Ethernet by default. I'm not clear what
you mean by "storing" the ISP info, since I assume that data is
streaming from the central office/hub at all times. Based on
conflicting info I've gotten you may be onto something.
I have been assuming a router is just a "splitter" and the LAN ports on
a router are functionally identical to the single LAN port on the modem
itself - like splitting a USB connection. Not that simple?

Hmm...we might be talking at cross purposes here regarding the router. I |
assumed you meant an ADSL router, which has an ADSL modem built into it
as opposed to a 'router' (most people these days seem to drop the 'ADSL'
part when talking about ADSL routers) ....but back to the ADSL modem.
When using an ADSL modem all your account info...I.E. username,
password, connection type (PPoE, etc), WAN Settings, MTU, MRU and
whatever else, are stored on the PC in the same way it was stored when
using a dial up modem, so what would happen when you disconnected the
PC, I am not sure, but I doubt if the connection would be maintained.
(As I said before: 'I stand to be corrected if I am wrong!)
The only two ADSL modems I have used had a USB connection (although one
also had one Ethernet port, but both (modems) were powered via the USB
port so disconnecting/shutting down the PC caused them to lose power.
(I now use a wireless ADSL router although it does have 4 ethernet ports
on it as well (DLink W604G))
With an ADSL router, all that info is stored in the router itself in a
similar way that your PCs info is stored in CMOS, so that the router can
be turned on and it will connect to your ADSL account..all without a PC
being turned on. With an ADSL router, connecting an IP camera to it
without a computer is easy (once the camera has been 'setup' of course).
You might find it a whole lot easier to simply buy a 4 port ADSL router.
I don't know how much they are where you are, but here in AU, the price
difference between an ADSL modem and an ADSL router is only a few
dollars (for the cheaper ADSL routers).
Of course..you can always simply try it out and see what happens!...I
would be interested in knowing if it worked....if for no other reason
than I would be proved wrong! :-)
In summary, my personal opinion is that it won't work! :-( |

I am looking at an under-$40 (USD) router by Belkin or Linksys. It
would have no built in modem, just connected downstream from same.

There is no USB involved with my Comtrend brand ADSL modem. I am mostly
interested in seeing if someone has a network camera and could try
running it directly from the modem without a router in the path. From
what I've gathered, it would probably work, but it would be hard to do
the initial setup without the PC online at the same time.

That's looking like the wisest course of action! I was just trying to
go cheap on this setup. I'm still not sure what you mean by info
"stored" in the modem and/or router. I thought it was only an active
connection IP grabber.
