Productbeschrijving
De intelligente camera met dubbele belichting van Dahua maakt gebruik van geavanceerde H.265 intelligente encoderingstechnologie met een hoge encoderingsefficiëntie. Dit levert video van hoge kwaliteit en verlaagt tegelijkertijd de transmissie en opslagkosten. Deze serie integreert intelligente warmlicht en infraroodverlichting, detectie van menselijke gedaantes, actieve sirene en lichtafschrikking, en andere functies, waardoor retrospectieve bewaking, interventie en voorzorgsmaatregelen mogelijk zijn.
De Dahua-camera is uitgerust met een ingebouwd intelligent videogebaseerd analysealgoritme, dat intelligente functies zoals Tripwire en Intrusion kan implementeren om snel en nauwkeurig te reageren op bewakingsgebeurtenissen in een specifiek gebied, wat de bewakingsefficiëntie verbetert.
De camera levert levendige beelden, zelfs onder de meest intense lichtomstandigheden, dankzij toonaangevende Wide Dynamic Range (WDR)-technologie. Voor toepassingen met snel veranderende heldere en zwakke lichtomstandigheden optimaliseert WDR zowel heldere als donkere delen van een scène tegelijkertijd om bruikbare video te leveren.
Smart H.265+ is de geoptimaliseerde implementatie van de H.265-codec die gebruikmaakt van een scène-adaptieve coderingsstrategie, dynamische GOP, dynamische ROI, flexibele multi-frame referentiestructuur en intelligente ruisonderdrukking om video van hoge kwaliteit te leveren zonder het netwerk te belasten. Smart H.265+-technologie verlaagt de bitsnelheid en opslagvereisten tot 70% in vergelijking met standaard H.265-videocompressie.

Great room divider
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
This is a room divider and would work great as one! I’m using it as a cover for my car port/garage so you can’t look in and see my messy garage as easily and for what I’m using it for it’s a little not quite as sturdy as I need it to but I’m sure it’s not meant to be used outside anyways so I don’t fault the product since I’m not using it as intended… with that said though…. It still covers my garage beautifully and really does exactly what a I need it to! I’m sure the wind may blow it over if it gets too crazy but I don’t see it breaking by any means. The frame is metal and drilled together using long screws. It’s very well built. The cloth for the panels is this waterproof type material that’s kind of like the gazebo roof feeling. So it’s easy to clean and it’s easy to wipe. You can put it straight or bend the panels and either way it still stands up. You don’t HAVE to bend it to make it stand or anything. You can literally use it straight across like I am in the pictures. Overall very happy with this product and it’s also very tall so it truly covers a lot (hides a lot lol). I’m 5’8 so you can see it’s taller than me by the pic I took

OK. Drag to setup. Needs more stable feet
Color: Black, Size: 4 Panel-88''
I was glad to find these.
The benefits of having them in a recording setup is helping suppressing noise for a vocal booth.
It's a layer that surrounds the recording box. Nice!
(But away from audio hardware or DAW).
Here is the not so nice part:
The feet!
It's able to stand (as it needs to do this). But it cannot be bumped. If it does, it's coming down onto something.
I believe the feet units are not wide enough (or long enough). That makes for an easier tumble risk. So far, they haven't, but it's like being in the woods over leaves - it feels dangerous with every step! (That's actually true).
They are tall enough, wide enough, material OK. But the feet for the main assembly do not seem sturdy enough.
There are ways to help that.
I'm thinking a 2x4 to augment the base. Make them wider. It can be done. It was a drag to set these up, and I'm sure to modify them like i'd want them. But, they do come in at a much lower price that other similar dividers.
Consider all this because I've seen more solid dividers ( with padding) that would basically be the 1/2 cost of these. But i'd think they'd be easier to assemble, stand sturdier, and without that feeling of an impending fall (or fail).
This is my opinion. I hope it helps.

wrong size of metal components. incorrect items. non functioning
Color: Black, Size: 4 Panel-88''
The owner of this product sent me the incorrect pieces when I tried to install. It didn’t fit. The pieces were missing holes and once I connected the wrong pieces after knowing now they’re stuck and I can’t return them even though Amazon was kind enough to refund me. I just want to warn people this product is such a disappointment because it looks good. It’s good price, but you can’t even assemble the thing very disappointed.

Sturdy Folding Room Divider with Good Privacy Coverage and Modern Look
Color: Black, Size: 4 Panel-88''
I picked this room divider up to help separate space in a room without needing permanent walls, and overall it works very well for creating privacy while still looking clean and modern.
The size is one of the biggest advantages. At 6 feet tall and roughly 88 inches wide, it creates a noticeable visual separation and works well for apartments, dorms, offices, studios, shared rooms, or content creation setups where you want to hide clutter or define different areas.
The black fabric and frame design give it a simple modern appearance that blends easily into most spaces without looking overly decorative or outdated. It has a clean minimalist look that works especially well in offices, bedrooms, gaming rooms, or studio environments.
Assembly was fairly straightforward overall. Once fully put together, the divider feels reasonably stable for normal indoor use. The folding panel design also makes it flexible enough to angle different ways depending on the room layout.
The portability is another strong point. Since it folds down, it is much easier to move or reposition compared to permanent partitions or heavier wooden dividers. That makes it practical for temporary privacy setups or changing room layouts frequently.
Privacy performance is solid visually. It blocks sightlines well enough for changing areas, workspaces, video backgrounds, or separating sections of a room. The fabric also softens the space slightly instead of feeling harsh or industrial.
One thing worth noting is that while it provides visual privacy, it is not soundproof. It helps define space and reduce some openness, but conversations and noise will still pass through normally.
The material quality feels decent for the price range. The frame is lightweight but functional, though I would still avoid rough handling or constant aggressive repositioning over time.
Value for money is good considering the size, flexibility, and convenience. Similar room dividers can become expensive quickly, especially for taller multi-panel setups.
Overall, this is best for anyone needing an affordable flexible way to create separation and privacy in shared or open spaces. It works especially well for apartments, dorms, offices, studios, remote work setups, or content creators wanting a cleaner background without permanent construction.

Looks nice but it's not very stylish, works as intended, happy with purchase
Color: Black, Size: 4 Panel-88''
This 6 ft room divider is exactly what I needed and works great! It was very easy to set up and took only a few minutes to assemble. I was pleasantly surprised by how lightweight it is, and it folds up easily for storage when not in use.
The fabric-style panels look nice and provide good privacy, and the included clips help keep everything neatly in place. It’s a simple but effective design that does what it’s supposed to do.
Because it’s lightweight, it may need a bit of extra support depending on where you place it—I used small weights on the base, and that completely solved the stability issue.
Overall, I’m very happy with this purchase. It’s practical, easy to use, and a great value for the price. I would definitely recommend it! Industrial
