If I was planning on buying a unit to receive wireless cameras, I would never buy the IC-R3, I would buy a dedicated device instead. For anyone looking for one of these, you might want to check this out:

Specifications from the website for those who might be interested:
* Full Range Frequency Scanning from 900MHz ~ 2.52GHz
* 2.5" High Resolution Monitor
* LCD Display Shows Frequency and User Setting Details
* Full Range Video Protocol auto-switching for PAL / NTSC, CCIR / EIA
* Dual Power "AA" batteries or External AC adaptor (AC adaptor optional)
* Auto and Manual Scanning Modes
* "Fine Tuning" Rocker Switch for use after alert
* Battery life indicator on LCD
* Antenna Sensitivity Indicator on LCD
* Audible Alarm on/off Indicator on LCD
These devices are so sensitive that you will likely find yourself receiving wireless video sender feeds as you scan through. They are great for privacy uses too or counter surveillance.Batteries will last you about 3 hours by the way.
