My buddy got some for $70 that work good. I know camtrakker and some others have a feature where you can turn off the flash, but don' t know if the cheap ones do. Maker sure there is no flash on or the intruder will load his gum with snuff, unzip his duffle bag, remove his limb saw, kneel while cutting down the tree you have it strapped around (assuming you didn' t strap it to a big tree), and have himself a new motion camera to take back after he hunts your stand!
