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.

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

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.

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.

Hello, I want to buy a new dahua SD42212S-HN, it seems perfect, any one know where i could buy in US? As i also find some guys selling from China, if it's good to buy from China? Thank you so much. Andy

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.

Hello Folks, Is there anyone buy this camera yet? Because i want to use this for my client's shop, it's a place that 120square meters, could this one work well? Powerful 12x optical zoom Max. 25/30fps@1080P & 50/60fps@720P DWDR, Day/Night (ICR), DNR (2D&3D), Auto iris, Auto focus, AWB, AGC, BLC Max 300°/s pan speed, 360° continuous pan rotation Up to 255 presets, 5 auto scan, 8 tour, 5 pattern Built-in 2/1 alarm in/out Support intelligent 3D positioning with DH-SD protocol IP66, POE+ Thanks.

Correct, the firmware just could be in English, when new one comes, all can't update anymore. But anyway English firmware is bit more expensive, this is the way Hikvision to protect their market in the world.

The cameras on Aliexpress are using Chinese firmware, as now Hikvision has a very strict control for the firmware, so you could only update the firmware to a fixed version, if new one comes, your side can't update then, and these cameras are selling in Chinese market, just some guys buy on Chinese market and sell overseas. That is why so cheap from China, but anyway, it would be good if you just for your own using, quality is still nice.

How about use Dahua HDCVI cameras? They are cheap, but if send form China, this still can't cover your cost. So it's bit hard to find such cheap ones, but mostly cheap ones poor quality. That is it.

most hidden cameras are low resolution and don't have nightvision, so i think you could buy some professional cameras.

Hi John, What is the space of this school? I think you could use PTZ is ok. No need to have such 10pcs, maybe 3-4 pcs is Enough, i think dahua SD59230S-HN, this is nice. But i don't know your budget, i could supply you this. Thanks. Andy

i am afraid most cameras on the market are visable, but i think the thief won't come if they see the infrared.

What is the budget do you have? I recommend dahua SD59230S-HN, this camera has 2Mp Full HD 16x Digital Zoom 30x Optical zoom , it works very nice, so you could record it anytime, and then you will know when your neighbor do such stupid thing. Hope this could help you. Andy

For baby using, i think for Dahua is much better, it is a fixed camera and has 3.6mm lens.IPC-K100 this camera is not wifi, and could have a nighvision for 6meters, so it won't have strong IR, it suits for your baby room. Most of all, could watch through your phones using the app. Hope this could help you. Andy
