It's funny reading that others had problems with this vendor. I just ended a 4 month fight with "Leo" from surip at Aliexpress. He sold me a cheap and defective bullet camera, and then proceeded to string me along, asking me to try different things to get it work, then not bothering to read my responses. A few weeks in he conveniently decided that I was merely trying to rip him off and get a refund, and then spent another ~3 months accusing me of lying. Aliexpress agreed with my pics and uploaded video, but it still took a long time before I got any refund and it was AliExpress who did it, not Leo / Surip.
I'm an engineer working a very high tech sector. His product is cheap, poorly thought out with weak firmware. You might be tempted to buy it as it's cheap, but save your money. The camera I bought is one of these limited H.264 cameras with awkward specialized ActiveX's which require security to be relaxed, and do not work in all browsers.
An amateur and aggressive supplier. Considering how long he fought against refunding me half the original purchase cost, I would not be surprised if he pops up here.
