EMEET 1080P Webcam with Microphone,C960 Web Camera,2 Mics,90° FOV,USB Type-A & A-to-C Adapter,Plug&Play Computer Camera for Online Calling/Conferencing,Zoom/Skype/Facetime/YouTube,2025 Version
I like to control the function of my equipment. Regrettably I have to give only a 3 star review because the shutter is a sticky tab with a plastic piece that moves up and down and it snapped off before I could even attach it to the camera. BUMMER
Now if the manufacture would send a replacement cover I'd happily give a 5 star review because the camera seems to be fine for the price point.
I can’t give this enough stars! I use my laptop for zoom but I have a monitor I look at that the laptop is connected too, so when I used zoom with my laptop camera and looked at my monitor you could use see the side of my face in zoom.
I only have usb c option on the side of my laptop to plug this in, so I did have to buy an adapter from USB A female to USB C, however they came at the same time and it was the easiest plug and play. It sits atop my monitor perfectly and has a privacy tool you can use.It sounds great and the video is flawless!
Great quality. I purchased this one as it had the most positive reviews and I'm glad I did over the expensive ones.
They promise a lot with this webcam and the quality was just bad. And as I had to use it to figure that out, I just got 50% refund from them as it was used + I had to pay the return shipment. Don't waste your money and time with this product and the seller!
Super Kamera.Hervorragendes Bild, perfekte Steuerung.Sehr gutes Preis/Leistungsverhältnis. Sehr zu empfehlen
This is an excellent webcam for the price. I bought it for streaming and have been happy with the video quality overall. It has a sharp image if you have good lighting and comes with a privacy door to put over the camera when not in use.
I don't use the microphone on it so I'm unsure about the quality of the mic but I'm happy with everything else.
Bought it due to high good reviews of saeid camera. Yes, it is good camera with affordable price and for school zoom usage.
