Productbeschrijving
De Dahua SD49825GB-HNR is een 8 MP gemotoriseerde PTZ-camera (Pan-Tilt-Zoom) die een geavanceerde bewakingsoplossing biedt voor buitenomgevingen. Dankzij de 25x optische zoom, Starlight-technologie en infrarood met groot bereik (100 m) legt hij heldere beelden vast, zelfs bij weinig licht.
Deze camera is voorzien van geavanceerde kunstmatige intelligentie (AI) en WizSense-functies zoals gezichtsdetectie, perimeterbeveiliging en SMD 4.0, waarmee het onderscheid tussen mensen, voertuigen en levenloze objecten wordt verbeterd.
Met zijn IP66-bescherming, 6000V-bliksembeveiliging en brede temperatuurbereik (-40 °C tot +65 °C) is hij ideaal voor buiteninstallaties onder extreme omstandigheden.

Works amazingly as intended, good value
Color: White, Color: White
Writes perfectly on my ipad. Worked immediately on my Bluetooth, didn’t have to connect. Holds charge very well from what I can tell. I finished a 10 hour long drawing process without it dying. I’ll update if anything changes. Comes with extra nibs.

Worth the money
Color: White
I have only used the pencil for a couple days, but it is definitely worth the $10 price. It easily turns on, needs no Bluetooth to use, has a battery indicator, charges very quickly, has extra tips, and works well.
The only issue I have on my 11th generation A16 iPad, is when the pen is magnetically attached, it covers part of the volume down button and sometimes causes volume mute.

works just like a name brand apple pencil!
Color: White
i wanted an apple pencil with my new ipad but absolutely refuse to pay the cost of the name brand. this connected/paired super easy and even had the magnet in it to connect to the size of the ipad. i mainly use it for playing games, navigating my ipad, and sometimes coloring and its easy to maneuver! it comes with 3 different tips for different sized writing if youre one to take notes. it charges super quick, id say within 10-15 minutes, and the charge lasts (depending on use) HOURS! i think i maybe charge it every 2-3 days, and i use it quite frequently. overall a really good dupe if youre balling on a budget like me!!

WOW! This printer has been VERY impressive thus far *UPDATE*
Color: Black, Style: ET-2800-B, Pattern Name: Printer
My old printer broke (sooner than I would have liked) so I did A LOT of research before deciding to buy this Epson EcoTank printer for home office use. This is my honest review of it this far and I will definitely update my review if I run into any issues.
So far, this printer has been pretty impressive (I've been using it for about a month). The price was pretty average for a printer... but I personally think all printers are overpriced so it was a bit more than I would have liked to spend. It is smaller and more lightweight than I was expecting which is a plus because it takes up less desk space than my previous HP printer.
It is very easy to set up, comes with step-by-step easy instructions and guided instructions through the app. It only took me about 10 minutes (Mostly just waiting for the printer to initialize on its own). It is very easy and surprisingly satisfying to fill the ink tank. I like the idea that this ink might last longer than traditional cartridges and won't have as much plastic waste that went along with my old HP Inkjet.
I have printed plain black and white documents as well as photos. I print all my photos at home, which is most of the printing that I do, so quality was important to me. The photos came out with pretty good quality! No ink smudges or off colors, colors are bright/vivid, and it is easy to modify what paper you're using with automatic prompts on the printer.
Now for the negatives and the reason I'm giving this 4 stars... app to printer connection issues. This was a big issue with my old printer as well. I'm pretty tech savvy and I just have no idea why this is still always an issue for me. There is an extra Epson app that you are supposed to download for printing. Sometimes it can find my printer, sometimes it can't. Sometimes it gives me printer errors or won't let me print documents. And now every time I go to print something it says the paper being used doesn't match the paper settings so I have to bypass that error message (even though it does match in settings and the app, and this happens for both regular paper and photo paper). I've turned everything off and back on again, but the issues with consistent connection and error messages are still an issue.
Usually with some fiddling around, I can get the documents/pictures to print but sometimes it feels like I'm jumping through unnecessary hoops. I'm still working out the kinks so if I find some magic solution I'll update my review. Considering this is an issue with most home printers I've used, it's not a deal breaker.
All in all, if you are looking for a new home printer, I would definitely recommend this one. The quality has been great for me and I am pleased with my purchase (so far).
Hope this helps!
*UPDATE*: I have now printed HUNDREDS of photos, they are all excellent quality, and my ink tanks are still mostly full. This is WAY better than my HP printer as far as ink longevity. Changing my review to 5 stars just based on how long this ink lasts. User interface is still a tad annoying but so worth it regardless.
