Wireless surveillance system

There are basically two choices in wireless video:
(1) inexpensive junk with no penetration and such short
range as to be viturally useless;
(2) really expensive stuff that works really well.


None of the residential RF cameras are encrypted, nor
do they use exclusive frequencies.  Basically, if you
send it anyone nearby can view it.  On the plus side,
the video is of such poor quality that the neighbor won't
be able to tell the difference between "marital bliss" and
reading the newspaper.  Of course, after a certain age
these may be one and the same.

If there's any way to run new cables, by all means do so.

Thanks for the comments, I appreciate it.

How about this though:

http://www.homeplug.org/products/

If I understand correctly, this technology sends audio and video through
the existing power lines, kind of like X10 does. Does anybody have any
experience with HomePlug?

I have had great success with this product, can be viewed from a remote
location via internet, uses your computer for storing video, and uses house
wiring for camera power and video transmission...................I have 6
cameras set up..................

I would think this would be a natural. No need for added wiring yet with
built-in security features so outsiders cannot access the video.

There are a few other manufacturers of HomePlug cameras or HomePlug camera
servers...

I have to admit the Gigifast setup looks interesting.
I didn't see any pricing for the remote component (camera,
transmitter),
and apparently you also need a 14Mpb router to integrate into
your network.

Sorry - I can't help on pricing but you'll probably have more luck checking
European dealers as HomePlug penetration is much greater there than in the
USA.

You will need a bridge from the powerline to your network.

Thank you all for the advice!

1) How good is the image quality? Cable quality? Dvd quality? Antenna?
2) Can other home appliances get fried accidentally?
3) The usb receiver needs some software (provided), which I assume runs
under Windows. I run exclusively Linux on my pcs though. Can the images
be handled by the v4l/v4l2 drivers? I know how to grab images via v4l and
I can write my own interfaces, as long as I can access the usb port via
the v4l drivers. Is there anything needed? Some usb stuff, maybe? Perhaps
I should ask this question in a Linux newsgroup, but I'm asking it here
too in the event that someone is using homeplug under Linux.

4) Would I need repeaters, etc. as you do sometimes with X10?
5) Won't the transmission spread to networks beyond my house? Won't my
neighbors see what's being transmitted if they plug in their own usb
receiver?

Most of the major players (Lynksys, Netgear, D-Link) have sold HomePlug
modules for a few years and I don't recall seeing a phase coupler so my
guess is the higher frequencies used pass to the opposite phase with no need
for a phase coupler.


The transmissions can be encrypted so only those with an Ovaltine secret
decoder ring can view them.

Most of the companies have sample video on their web sites.

If you go with a HomePlug camera server, you can use the network camera of
your choice.


I don't understand the question. Why would other appliances be affected?
HomePlug has been in use for a few years (it's much more popular in Europe)
with no epidemic of fried appliances.
    

The WiLife cameras need Windows Media Player. My guess is that if you can
deal with .wmf files you'll be OK but that's a guess.

This is excellent quality! I imagine much better than wireless?

Thanks for all the info!

Be careful about putting a lot of data on your home wiring if you
intend on using other PLC devices that control lights.  Baby monitors
are well known for wreaking havoc with x10 systems, (but x10 is pretty
unreliable to begin with).  I would opt for a hard-wired system any
day if you can get the wires pulled, or just make a few of the harder-
to-wire cameras use RF.

HomePlug uses frequencies that are much higher than those used by X-10 so
there's no interference with X-10, Insteon, etc. The newer HomePlug AV
devices can handle multiple streams of HD video so they should be capable of
handling surveillance video.
