Frequently Asked Questions
Which webcam should I buy for online classes?
Entry-level models such as the A4Tech PK-810G run at 480p with a built-in microphone, which covers voice-led classes without loading your connection. If your classes involve screen sharing or you want a sharper picture, move up to the 720p HD or 1080p Full HD subcategories. Both sit within a narrow price spread of the entry models.
Do these webcams include a built-in microphone?
Some do. The A4Tech PK-810G is listed with a built-in microphone, which lets you take calls without a headset. Check the individual product title and specification, because microphone support varies by model.
Can I order a webcam if I am not in Karachi?
Yes. The showroom is in Karachi, but orders ship nationwide across Pakistan. You can pay cash on delivery or complete the payment online.

Webcams in Pakistan
Webcams carry the video half of every call taken at a desk, and this section groups the webcams in Pakistan that Mega Computer stocks so you can move to the resolution tier you need without scrolling past the rest. The buyers who land here split into two groups: people fixing a video problem on an existing setup, and people building a desk from scratch who want the camera decided alongside the monitor and headset.
A4Tech supplies the models held at this level of the catalogue, including the PK-810G and the PK-635G, both anti-glare units. The PK-810G is listed at 480p with a built-in microphone, which places it at the entry end of the ladder. Deeper stock sits in the subcategories rather than on this page, and the spread across the whole webcam range stays narrow, running from entry-level clip-on cameras through to premium models without a large gap in the middle.
Three decisions settle most webcam purchases.
- Resolution comes first, because a higher tier consumes more upload bandwidth and more USB throughput, and a connection that struggles will drop frames no matter what the sensor can do.
- Audio comes second: a built-in microphone, as on the PK-810G, removes one cable from the desk, while a separate headset gives cleaner voice pickup in a shared room.
- Third is glare. An anti-glare lens matters when the camera faces a window or a ceiling light, which is the usual cause of a washed-out picture on a home desk.
Matching a webcam to your setup
Students joining classes on a laptop or an older desktop should start in 720p HD Webcams, where the bandwidth demand stays modest. Office staff running scheduled calls on a fixed connection get the most from 1080p Full HD Webcams, the tier most conferencing software treats as its working standard. Streamers who need a camera to hold up next to game capture should look at Gaming Webcams. Anyone recording to edit later, or filling a large frame on a wide monitor, belongs in 2K QHD Webcams or 4K Webcams.
Mega Computer has traded in computer hardware since 1986 and keeps a showroom in Karachi where you can see a webcam mounted before you buy. Orders ship nationwide across Pakistan. You can pay cash on delivery or settle online, and warranty terms differ by brand and model, so confirm the cover on the model you choose at the point of purchase.
Check two things before the camera arrives. Confirm you have a free USB port that is not shared through a loaded hub, since a webcam competing with an external drive on the same controller will stutter. Then look at where the camera will sit. A clip mount needs a monitor bezel or a laptop lid it can grip, and placing the lens with a light source behind you is what an anti-glare coating is there to correct.
