Electronics
Laptop cameras still ship at 720p with grainy low-light performance, so a good external webcam is the cheapest upgrade to how you look on calls. But spec sheets push resolution while the sensor size, lens and exposure processing do the real work — a well-tuned 1080p camera beats a bad 4K one. Here's what to check.
Quick answer
A 1080p/60fps webcam covers most people on calls.
Sensor size, lens and autofocus matter more than the resolution number.
A physical privacy shutter is the only guarantee software can't bypass.
Fix your lighting first — move to 4K only for content creation.

Answer all 3 questions to see the spec sheet to shop with.
For electronics the expensive failures are the display, the board and the battery. Extended cover is worth it only when it names those parts and offers a repair path in your city.

Usually not covered
Rule of thumb: worth considering on a high-value device you carry around, rarely worth it on a low-cost one where a plan costs more than ~15% of the price.

Buy it locally
Sometimes the local dealer beats online on price, installation or the exchange offer. Tell us where you are and we'll list nearby stores. We don't rank or take money from any shop; results come from Google Maps.
The area you enter, or coordinates rounded to about 1 km if you use your location, are sent to Google Maps through Lovable to find places. Lookups are temporarily cached for up to 30 minutes.
1080p is the call standard; 60fps looks smoother; 4K helps for cropping and recording.
Why it matters
Meeting apps often compress to 720p–1080p anyway — frame rate and sensor matter more.
What to check
'4K' cameras with tiny sensors look worse in dim rooms than good 1080p ones.
Bigger sensors and wider apertures (f/2.0 and below) gather more light.
Why it matters
Light gathering decides how you look at 8pm under a tube light — the most common real-world test.
What to check
Marketing hides sensor size; reviews with low-light samples are the truth.
Autofocus keeps you sharp when you lean; FoV (65–90°) sets how much of the room shows.
Why it matters
A 65–78° view frames one person well; 90°+ suits groups but shows your whole room.
What to check
Fixed-focus budget cams blur if you move closer than arm's length.
Built-in single or dual mics with noise reduction.
Why it matters
Fine for solo calls in quiet rooms; a headset or USB mic still beats any webcam mic.
What to check
Don't pay extra for webcam audio if you already own a decent headset.
Physical shutter, status , and a clip or tripod thread.
Why it matters
A shutter is the only webcam privacy guarantee that can't be bypassed by software.
What to check
Thin laptop lids defeat some clips — check for a tripod screw as backup.
Auto-framing, background blur, HDR, exposure controls via companion apps.
Why it matters
HDR genuinely helps with bright windows behind you; auto-framing is a nice-to-have.
What to check
AI-tracking gimbal cams are clever but solve a problem most desk workers don't have.
₹3,000–₹6,500 (≈$36–$78) is the sweet spot for call quality. Creator-grade 4K cameras run ₹12,000–₹20,000 (≈$140–$240).
