I bought these to display security cameras on TVs in an air conditioned office environment. They both failed within three months. One would not even power up. One would not respond. I recommend you do not purchase the inexpensive devices. I replaced them with little better fanless PCs from a different manufacturer and have had no problems. A 30 day warranty is good enough for the seller but is way too short for the buyer. Can't contact the seller. Don't buy.
