That Man

The neighborhood has gone to hell it seems, and I'm installing security equipment. Like many of the posters here, I'm new to security cameras. I have come up with a preliminary design for home security, but I don't know if I'm missing anything, or if I'm specifying parts that are correct for the application, and was hoping I could get some feedback from the more experienced among you. Here is my plan: Position 1: ACTi TCM-1231 - Bullet Camera http://www.acti.com/product/detail/Bullet_Camera/TCM-1231 Position 2, 7, 12: ACTi KCM-3911 - Fisheye Camera http://www.acti.com/product/detail/Fixed_Dome_Camera/KCM-3911 Position 10: ACTi GNR-2000 - NVR www.acti.com/product/detail/Standalone_NVR/GNR-2000 Am I missing necessary components? Am I misapplying the parts? Any criticism that isn't downright trolling would be appreciated. Thank you all for your time.

Apparently, the ACTi KCM-3911 isn't rated for outdoor use. I'll have to switch position 2 and 12 to the ACTi KCM-7911, which is a couple hundred dollars more expensive. Does anyone know of a more affordable high quality outdoor fisheye? That markup for an IP 67 housing seems a bit high. Also, what is a video management system, and do I need one?

Here is an updated plan: *Mods - I noticed the link to the image in my first post was changed. If I should be linking to images in a different way, please let me know how. Here is a network diagram: dahomes555, thank you for suggesting that I add a POE switch. Any other comments or suggestions?
