Productbeschrijving
De Dahua IPC‑HFW3449T1‑AS‑PV‑PRO is een 4MP IP-bulletcamera, ontworpen voor hoogwaardige bewaking buitenshuis. De camera is uitgerust met WizColor-technologie en TiOC PRO actieve afschrikking en maakt gebruik van dubbele IR en witlichtsignalen tot 50 meter, plus rood/blauw lichtsignalen en audio om indringers af te schrikken.
Het is uitgerust met een 1/1,8" sensor en een vaste lens van 2,8 mm, die beelden levert tot 2688x1520px bij 25 fps. Het beschikt over verbeteringstechnologieën zoals 120dB WDR, 3D-NR en ROI, en ondersteunt geavanceerde H.265+ / H.265 / H.264 / MJPEG-compressie om de bandbreedte en opslag te optimaliseren.
Een van de grootste troeven is de AI-analyse: detectie van lijnoverschrijding en indringing met persoons- en voertuigclassificatie, SMD4.0, AcuPick en AISSA. Het ondersteunt ook tweerichtingsvideo en audio (microfoon + interne luidspreker) en heeft alarmingangen en uitgangen.
Het heeft een MicroSD-slot tot 512 GB en ondersteunt PoE+ of 12VDC-voeding. De zwarte IP67-gecertificeerde metalen behuizing garandeert water- en stofbestendigheid, terwijl de 3-assige montage de oriëntatie vergemakkelijkt. Perfect voor winkels, ingangen, perimeters en gebieden die gevoelig zijn voor vandalisme.

Easy to assemble, and comfortable!
Color: Blue
I bought this chair for my teenaged son, who has a small student's desk in his room (also ordered and assembled at the same time). This fits perfectly for the small desk, and is reasonably comfortable for a medium-sized adult, teenager, or older child. Once put together, the chair itself appears to work flawlessly, seems comfortable enough, the height is easily adjustable, and of course -- the most important part, according to my son -- "spins silently 'round and 'round really fast for a long time." The blue color is a nice, deep blue hue that works well for him and makes it stand out a little more than your average black chair. I was able to assemble it fairly quickly without issues. My son uses it to sit in for his schoolwork and computer gaming/programming/hobbies at his desk, etc. and he says it's comfortable, even after sitting in it for 1-2 hours at a time.
With this type of chair, you're getting exactly what you pay for and what you see in the pictures. No more, no less. The price is fairly reasonable, it feels sturdy, and if you're looking for an easy and simple office chair for light task work at a computer desk for a teenager or college student with limited space, this is an easy win. While it's not the smallest office chair out there, it's certainly not a large one, either. I am a medium-sized woman at 5'4", and my bottom doesn't hang off of it; that said, a taller/bigger person might want to look into something a little larger for comfort, if they have the space for it. My son is 5'6" (and growing) and slim, so it works perfectly well for him. My husband, who is larger and taller than us, sat in it and said it didn't feel bad...but he was unsure how comfortable it would be sitting in it for longer stretches of time. So...your mileage may vary.
Overall, this was exactly what we were looking for and precisely what we expected for this product, so we're happy. I will update this review should anything change.

Great small rolling desk chair.
Color: Black
Small footprint for small office. Comfortable. Nice back support and super easy to assemble. Told my 300lb son he’s not to sit on it. It’s my chair.

Good as a task chair, but terrible for long-term sitting
I have revised and updated this review after two years after getting a replacement chair, downgrading it from 5 stars to 3 stars.
I have owned an office chair from Staples for two years. It was a $200 office mesh chair. It seemed pretty comfortable when sitting in it at the store. Unfortunately, it turned out to be uncomfortable for long sitting duration, I seemed to end up slouching often because it wasn't very supportive. The seat depth was probably longer than optimal for my legs. The mesh seating was not supportive. With these issues, I thought a task chair would be more useful.
But I didn't want to spend so much money on a chair again, so here comes Amazon to the rescue. This chair allows me to sit comfortably with a reasonable seat depth, so I'm now able to sit with proper posture. The foam base initially felt better than the mesh base. This all led to a 5 star rating. After a year and a half, however, it has come to my realization that the foam seating is terribly inadequate for long periods of sitting. Maybe after a year the foam was worn out to the point that it was no longer supportive. After long periods of sitting, I could feel the wood support base. I tried a seat cushion to no avail.
In the end, I got rid of this chair and purchase a chair from one of the high-end office ergonomic chair manufacturers. It cost 10x more than the Amazon chair, but it's night and day with regards to being comfortable. It is worth the cost to protect my back.

Very nice office chair
Color: Black
This is a very nice chair at a great price. The cushion and mesh back are really comfortable. It has great height adjustment and range. Assembly was easy. Exactly what I was looking for to use in my home office.

Love the design, comfort and ease
Color: Grey, Color: Grey
Assembly was a breeze with the Amazon Basics Ergonomic Executive Office Desk Chair. The instructions were clear and easy to follow, and I had the chair put together quickly without any hassle. This simple setup made the whole experience even more satisfying from the start.
In terms of comfort, the chair truly delivers. It provides excellent lumbar support, I assume it will make long hours at my desk much more enjoyable. The adjustable height feature lets me customize my seating position, and the flip-up armrests allow me to slide the chair neatly under my desk without worrying about damage.
Overall, I couldn’t be happier with my purchase. The chair looks stunning in my office and perfectly complements the decor. It combines style, comfort, and practicality at a fantastic value, and I highly recommend it to anyone looking to upgrade their office chair. I love you so much that I ordered another one for my husband’s desk.
