now that you mention itThat or maybe it stands for Sh*t Quality
less than $20, deduct eBay/PayPal fees and postage, it's not even a $20 camera, camera will be around $8 cost, don't waste your moneyI wouldn't buy a $20 camera and expect it to work anywhere near as well as the $100+ camera it's trying to copy.
The cost to ship it back to China if it doesn't work is more than 17usd. It may be okay as a DVR, but, thing like waterproof case etc would probably be useless. You are probably taking a gamble.
