I ordered 2* of this camera but the seller only sent me 1. Then when I wrote to them, it took a lot of hassle to finally get them to send me out the 2nd one. They also didn't have the 2.8mm in stock at that point so only gave me the 4mm. I am not awaiting the 2nd camera still. when something as simple as not sending the order that was paid for, it really causes stress, hassle and wastes time.
Verz good product. Original Firmware. Update runs perfect.
