needs SATA drive, and can be viewed with a 3G cell phone...

LTS High Power 240FT Long Range IR Camera, 540 TV Line Sony HQ1, 1/3in Sony Super HAD CCD, Japan Canon 8.0-40mm Varifocal Lens. Model: DVC-CMRH1060H.

same thing, just lower power Lens and IR LEDs, a good choice and $25 less...
LTS 36 IR 75FT 1/3in SONY HAD CCD Camera, 540TVL High Resolution, w / Vary-Focal 4-9mm Lens and Cable Managed Bracket. Model: DVC-CMR603WHI.
good for interior, or anywhere the camera is not out of reach... fully enclosed cable... needs to be WALL MOUNTED
LTS 36 IR LED Color Dome Camera, 1/3 Sony High Resolution CCD, 550 TV Lines, Model: DVC-CMD708W.
great interior camera.
CCTV 12V DC DC Power Distribution Box for 18 Cameras. 10A, w/ 18 LED. P/N: PD1218
Pay the extra for this... uses circuit breakers instead of fuses... you short a lead, reset the power and it's good...
Plug 2.1mm Camera Power Connector, Model: POWER21MM
these turn bare wire into a nice power connector -- DO NOT CUT YOUR CAMERA LEADS to splice bare wire, you will void the warranty.
DO NOT SKIMP ON THE WIRE, use RG6 Siamese if you can find it.
Black Coaxial Cable CC-R595/95/1000FT, RG59U Bare Copper Coaxial 95% Braid Siamese, 1000', Wood Spool, w/ 18AWG 2 Conductors
you will always need more wire than you think. it's on a spool, so use a cable caddy
BNC RG59 Connector Fits on RG59 and RG6 Coax Cable
you'll need a compression tool for these fittings... they are a little harder to install than F connectors... but you need BNC and the other option is Bnc adapter - F connector - cable - F connector - bnc adapter -- costs more and has more points of failure. expect to destroy your first 3 fittings

holy crap, a deal! with The stripper and The crimper...
get a pair of micro flush cutters to trim the stinger to a beveled point
check if you need plenum rated cable for your installation to be fire code compliant...
Does your state require you be licensed to install security systems?
If they do, contract out the camera install, hook up the rest yourself.
don't forget to let your insurance know you have a video system... expect a 15% drop in premiums...
short of screws, holes, butt splice or wire nuts and some good electrical tape you're good...
