Yes, analog cams are going to be way cheaper but you lose the metrics, notification \
,etc. In small office environments/home you want proactive notification. <snip>
Well, this is partly correct. Most modern DVR systems provide full notification \
functionality, and apart from software motion detection they can make use of motion \
sensors embedded in cameras (which is much cheaper, simpler and accurate than \
software motion detection). They can send e-mails, SMS, upload video files to FTP \
servers and they even provide applications for iPhone and Android devices.
In any case, it depends on the particular needs. My experience with cheaper cameras \
is that the video quality would be perhaps enough to recognize someone you know (e.g. \
your brother entering the house), but it would be difficult to identify someone you \
don't know/you don't expect. To be honest, I would feel much more comfortable/happy \
with an IP only system, but the cost was way too high in my case...
Good luck!
George

,etc. In small office environments/home you want proactive notification.
Yes, cams do come w/ logic built in; the MOST important is the ability to do motion \
detection on the camera itself. Most software packages these days will allow you to \
do motion detection on the camera or pull a feed down all the time and do motion \
detection on the server. I know synology, sony, and milestone all do this. The \
major advantage to this is you can drop cams at remote places and know that you're \
not going to be running a feed 24x7 using up all that bandwidth. Also, motion \
detection even on a modern cpu is very processor intensive; after 5 or 6 cams you're \
going to see performance issues unless you use beefy (costly & power hungry) \
hardware.
Even those little axis cams can do motion detection locally and then notify the \
synology system (for example). The 1011-W are reasonably economical; sub $200 and a \
4 pack is about $700. Picture quality is pretty decent to. For a little more ~$250 \
the M1031-W has two way audio, a pir, and light that can be tripped to illuminate the \
area.
On the notification, synology can email/sms/ftp; they've got a slick little android \
app that let's me just see "events" and I get an email when ever they are tripped.
There are 100's of options out there; I'm just sharing what I'm familiar with.
Good luck!

Having gone through the investigation of building a home security system recently, I \
have a couple of points that I would like to mention:
- IP cameras with sufficient video quality and night vision are very very expensive. \
If you haven't bought the cameras yet, make sure that the video quality that the \
cameras provide is sufficient for your specific needs/circumstances. Video quality \
depicted in vendor sites and manuals is far from true.
- Since you will be using a centralized recording, monitoring and management \
application, you will never actually use the software/capabilities that come with the \
cameras, so you will probably paying for features that you will never use.
- If you go with Synology (I agree with Liam that they have great products), keep in \
mind that the Surveillance Cam application that comes with their systems has license \
for only 1 camera. If you want to use more cameras, you have to buy an extra license \
pack.
Personally, I ended up buying a DVR system with old-fashioned PAL signal cameras. If \
you don't want to use coaxial cabling, e.g. because you already have UTP cabling in \
place, you can use special adaptors that convert coaxial to UTP (I don't know their \
prices, but I don't expect them to be very expensive).
In my case the system I built (3 cameras) cost less than 1/5th of the price I would \
need to pay for IP cameras for the same video quality.
Good luck!

The axis 1011-w and 1031-w series of cams support 802.1x and are inexpensive. They \
are quite flexible and run a stripped down version of linux so you can do some neat \
things with them. They also are ac 120 which may be a pro for you; the 1054 in that \
line is poe.
On software, Milestone has a free version of xprotect (Go) that is pretty decent on \
the windows side.
Sony also offers a free version of their Real Shot Manager product, although it only \
works with Sony cams. Sony makes incredible cams, however they are aimed and priced \
towards professional installs.
If you don't want to use a whole PC you may want to look into a synology NAS; they \
have a pretty full featured camera / security application with the new 4.0 DSM (OS). \
They suck down a heck of a lot less power than a full PC and there's a pretty full \
lineup of models to choose from. They can also double as your media server, \
webserver, nas, etc. We have a DS1812+ in the office that I love.
Good luck.

Dave,
I know there are inherit risk with wifi in general however that is why I was specific \
to say 802.1x authentication therefore meaning the use of PSK with WPA/WPA2 are not \
being used. When you have deployed a WPA/WPA2 Enterprise Level WLAN the WPA/WPA2 PSKs \
change frequently therefore making it extremely hard to gain access to a Enterprise \
WLAN network. So with that said are there wireless cams that can do 802.1x \
authentication? Or are they only capable of doing PSK?
Does anyone have any security information associated with Z-Wave?
http://en.wikipedia.org/wiki/Z-Wave
Or any security information related to X10?
