Productbeschrijving
De Dahua IPC-HUM4231S-L4-S3 is een moderne netwerkcamera uit de Pinhole-serie. Het apparaat is uitgerust met een 1/2,8" CMOS-sensor die beelden genereert met een resolutie van 2 MP 1920x1080px. De camera maakt gebruik van H.265-coderingstechnologie deze codec is ongeveer 30-50% efficiënter dan H.264. De camera heeft een vaste lens van 2,8 mm. Een videoverversingssnelheid van 25 fps bij 2 MP en de geïmplementeerde beeldverbeteringstechnologieën WDR 120 dB (digitaal breed dynamisch bereik) om de belichting in de scène in balans te brengen en 3DNR (ruisonderdrukking) vormen een perfecte combinatie, wat resulteert in beelden van hoge kwaliteit met zelfs de kleinste details. De camera maakt het mogelijk om twee onafhankelijke streams te configureren handig bijvoorbeeld voor het weergeven van livebeelden via netwerken van lage kwaliteit.

Thin, Light, Very Functional - Fantastic tablet
Color: Gray, Size: 256 GB, Style: Tab A11+, Color: Gray, Size: 256 GB, Style: Tab A11+
First off you only get a tablet, an USB-C to USB-C cable, quickstart instructions and Sumsung care info. That's it. No charger, no nothing else. Even the screen doesn't come with a protector, the tablet itself comes in a fabric/paper like bag.
So advice: Buy a screen protector and/or case for this tablet! It's very thin and light weight!
The tablet itself is fantastic. It plays all the games so far I threw at it, even the graphic intense ones. Compared to some Chinese ripoffs, this shines like a champ. The 256 gigs of space is plenty and 8 gigs of ram help alot! Truly the tablet is great for my use - Playing games and watching videos.
I'm a little upset for the fact that it doesn't come with any charging device, but my phone's charger works fine. The USB-C to USB-C cable may come in handy (but my old PRO12 tablet uses the older usb port).
Overall I'm very pleased with it. The games I played on my Moto G phone play fantastic on the A11+ plus it can play much more. Also I don't stream so I put videos on the tablet. My old tablet I had to convert them to make the compatible. The A11+ and Android 16 shines here. It can play most all my videos without conversion, even 4k HDR videos natively! And the sound it great with four speakers as well!
Only downfall is the warranty. When I registered the tablet says something about the country of origin so I don't have warranty for the tablet.
Just remember to have a charger for it, screen protector and I recommend a case!

All you need in retirement
Color: Gray, Size: 256 GB, Style: Tab A11+
Great purchase in comparison with Fire and the Tab S. Does everything I need it to do: read books, email, pay bills, chat, etc. The price was right and it's a good solid tablet without too much complications. I have a Samsung Galaxy smartphone so both are complementary to each other. One comment, Samsung does not provide an actual plug, just the cable...not the best customer service act for sure but seems like all of them are doing it now. Otherwise, I'm pleased with it.

No Fingerprint reader.
Color: Gray, Size: 128 GB, Style: Tab A11+
Nice tablet. I find the video quality to just OK. That may be because I haven't found the optimal settings. The biggest drawback is my fault for sure. The tablet doesn't have a fingerprint reader. All my phones and previous tablets had that. I now know it a higher end feature. But as a casual tablet this is fine.
