over the last 12 years we have tried about 10 brands of cams. We settled on Stealth Cams. You can buy older model year units for less than $50.00. SOMETHING TO KEEP IN MIND: If using multiple cams try and use the same brand. For awhile we had 4 brands and made many mistakes setting them up. All cams have different ON/OFF/SETUP button positions. Often I had turned one off thinking I turned it on because of position of switch. Getting old (72) might have something to that but not always.
