Home Security Answered

I'm planning on setting up a simple home security system for my home. I was thinking of using Wireless IP webcams, placed in strategic locations, monitored by software with a motion sensing function. I would tweak the sensitivity and add null zones as needed. I would probably only use two or three cameras to start out, and have the software save ten or twenty seconds of video when the motion sensor was triggered. EASY. Once I have the motion sensing bugs worked out, I'd like for the software to email/text message me. I think most of the security programs for webcams out there can do this. I've had good experiences with one program that also let you run an image server so you can view current images through the internet. The TRICKY part is how I would like to set up the network of wireless IP webcams. What I was hoping to do is have one machine that was dedicated to running the cameras. My goal was to use my two wireless routers so that I could have two seperate networks, one for the cameras, and one for all the other devices (laptops, desktops, game systems, printers). My question is, do I connect the router for the cameras to the computer that will run the security software, or do I plug that router into the router for the other devices? I've never worked with two of these small LinkSYS routers at the same time, so I'm not sure if I should be trying to create some sort of network bridge, or if I would maybe connect the camera router and camera computer via the WAN port of the router, since all of the camera images would be displayed on a image/web server running on that computer, accessed from the internet via the other router. Also, I've never worked with wireless IP webcams, so if there is any sort of quirck that I should know about that your average instructables user couldn't figure out, any help or advice with that would be much appreciated as well. Thanx Tony P.S. Eventually, I'd like to add in a strobe that would blink and a siren that would sound for a short time. I think I could figure this part out with "Pico Servers" and some relays.

If you're using 2 routers, be aware that you typically will not be able to pass data/information "down" through one of them. Example, if you connect your cameras to one router and connect that to your second router which has your PC, you may have trouble connecting to the cameras from the PC to set them up (I am assuming each camera has a web interface you access to set them up). Likewise, if you connect the cameras to your top-level router with your PC behind a second router, your cameras may have trouble sending their video over to the PC. Now there are ways around this. An internet (eg. Google) search for "port forwarding" may help you set it up so it all works. Just be aware that allowing traffic into your network means that potentially anyone can get in (though it may take some effort on their part). If the webcams allow you to set up passwords or something so that anonymous users out on the internet are not able to log in and spy on you, then be sure you set up good passwords. These are just things to be aware of. There's a solution to every problem, but every solution brings it own potential problems. As long as you're conscious of the security implications you'll be fine. P.S. There's a terrific security netcast/podcast called Security Now where they have at times discussed the very topic of port forwarding and "stacking" routers in the way you describe.

I think I'm going to go with a "donated" copy of WebCamXP-Pro for the monitoring... I'm still not sure on how exactly I want to set up my netork, but it would be nice to have two seperate LAN segments to isolate the cameras. What I would really like to do is figure out a way to have an alarm and strobe on some door sensors, or motion detect, but not go off continuously. Just enought to get some one's attention, and let them know that they're busted. There will be outside signage as well as placars explaining that their motion sets off a recording system seperate from an alarm or strobe that will record their images to be used as evidence. The more the "bad guys" know that they will be caught, the less likely they will be to break in, if there are unsecured homes they can break into instead.
