Back to the factory resetting, that is OK.

dahua is very good brand now, and the camera now we are using is not bad, and work perfect, good price for good product. Any way, you could have a try, i buy some SD50230S-HN today, seems this is a new ptz, but without nightvision.

1. Pls check if the IR LIGHT CTRL is ZOOM PRI (pls check details on the user manual page21) 2. Pls test zoom in dark. This camera support 30x Optical zoom. Pls zoom step by step till 30x optical, and notice the change of IR lights. 3. If still remains the problem of the IR light, pls ask client to let our tech to check remotely via Teamviewer. Here are the feedback from the seller and we lastly solve the problem, the IR light is OK now, seems i make some small mistake, but they are very patient for my complaint, seems nice. I left them a good feedback. Alexpress now selling many hikvision and dahua cameras, most sellers there are very kind.

Oh...no, the seller very kind and i already buy many from them yet. But this problem is the first time i met, how about hang it outdoor in the night for a try??

Yes, i already try, but seems not work. Is there anything wrong? Thanks.

Oh,that is terrible, in my mind, cheap items always worse quality and support. So the best way is to ask them for replacing the boards for you, replace them, this could help control the lost. Or else all are rubbish.... Then a nightmare.

Hello Recently i bought a Dahua SD6C230s-hn on aliexpress, but i meet a problem. Only two(The base 2LED was on) of the six ir leds are working. Is it possible there is a setting I need to change or is there a problem? The seller said i need to make different zoom then could make all LED lights on, what is the problem i meet? Could anyone help me for this? Thanks. Andy

where do you buy it? You could ask that seller to help you accordingly. That would be faster.

Good! I already buy from China yet, 100USD cheaper from China. Not bad Thanks.

we have a company in US too, i just compare the price in US and in China, as you know dahua offer their exclusive partner in US a very low price. That is why i ask, thank you Larry

most cameras are made in China, re-brand and sell a higher price there.So buy hikvision is OK

where do you buy this NVR? I never hear this brand before, you buy from China?

i think dahua SD59230S-HN could meet your requirement. It supports ipad/iphone/android phone watching, 2pcs i think 1400USD is enough. Here is the specification: High Definition: 1080P(Full-HD) Special Features: Waterproof / Weatherproof Model Number: SD59230S-HN Style: PTZ camera Focal Length: 4.3mm~129mm (30x Optical zoom) Image Sensor: 1/2.8' CMOS IR distance: 80meters Pan/Tilt Range: Pan: 0° ~ 360°endless;Tilt: -15° ~ 90°, auto flip 180° Manual Control Speed: Pan: 0.1° ~300° /s;Tilt: 0.1° ~200° /s POE: YES Format: PAL/NTSC Preset Speed: Pan:400° /s;Tilt: 300° /s waterproof :IP66

I find a seller on aliexpress, sell this model. Is there any guy buy from this website? Is it safe? Thank you.

so the camera's firmware is Chinese, and won't be a big problem for your own using. If you buy English firmware camera, that would be cost more, this is their selling policy.
