Analog cameras (NTSC analog video) are virtually obsolete and mostly unobtainable, especially in resolutions sufficient for security purposes. I have one that I installed in my detached garage several years ago. It uses a wireless RF analog link to a special receiver in the house. The receiver outputs NTSC color video, except at low light levels the output is monochrome. No microphone, so no sound. This rig is totally useless IMHO. Limited RF range from camera to receiver, poor signal-to-noise ratio, NTSC low-resolution image, no motion detection. It does work okay in the dark with built-in near-infrared LED illumination on the the camera, but that's the only thing it has going for it. I think I purchased this from X10 Home Automation for around sixty dollars.
The X10 latest camera offerings are only IP cameras, mostly WiFi connected.

@Ian mentioned also appear to be a good deal (I get e-mail offers for them from D-Link on a regular basis), although I have yet to purchase any cameras from them. My wireless cards are D-Link, my wireless LAN router is a Cisco-Linksys E3000 with four wired ports, and the Ethernet switch is a Cisco-Linksys SE1500 that adds four more ports while using up one of the four router ports. The LAN connects to the Internet via a personally-owned Motorola SurfBoard SB6141 modem connected to a Time-Warner cable service with "up to 20 Mbps" bandwidth. All this works together pretty much flawlessly... until someone fires up the 1200 watt microwave oven in the kitchen. Some of the D-Link wireless cards go off-line when that happens, hence my desire to use Ethernet wired ports for some of our PCs and the Toshiba camera. My wife's MacBook Pro and her iPad and my HP laptop don't appear to be affected by the microwave oven, so go figure.
Please re-think your desire for a non-IP camera. They are easy to install, the prices keep coming down, and you do not need the "services" of a "security" company.
