what's going on at the other end of the camera, working in conjunction with your home computer or even your smartphone to capture the evidence. Here's a couple of models offering wireless security... Zonet Wireless IP Cam Wireless 2-Way IP Cam w/Night-Vision. This Wi-Fi compliant with IEEE 2.4GHz 802.11b/g devices; supports both Infrastructure and Ad-Hoc Modes. We like that at least has 128-bit WEP and WPA-PSK encryption and that you can view and record video up to 16 cameras simultaneously with two-way voice communication. Additionally, you can capture video in super low-light situations, supporting 3x digital zoom, motion detection with 3 scalable windows, using web configuration with password protection. It has 6 IR LEDs for perfect night vision capabilities. Cisco WVC210 Wireless-G PTZ The Cisco WVC210 Wireless-G PTZ Internet Video Camera sends live video through the Internet to a web browser anywhere in the world. The camera supports dual codecs (MPEG-4 and MJPEG), which can be used simultaneously. MPEG-4 gives efficient bandwidth consumption with good-quality compression and is optimal for real-time viewing of video. MJPEG gives optimal video quality, making it ideal for large-volume storage to a network attached storage (NAS) device. Swann NightHawk Wireless Security Camera Designed to be a consumer level plug-and-play affair, the weatherproof Swann NightHawk offers 380 TV Lines of image resolution at up to 26ft of infra-red night vision. The system relies upon a wireless 2.4GHz transmission between camera & receiver up to 165ft/50m, and is meant to be hooked up to a television or compatible monitoring system. But note, unlike the other two systems above, this is not a wi-fi based system and might actually affect wireless networks (Swann also offer a wi-fi model called the ADW-300 offering similar nighttime vision and audio recording).
