1. Eufy S350 — The one that actually works in cramped spaces
The S350 runs two lenses simultaneously — one wide for room coverage, one telephoto for faces up close — and fits the reality of Hong Kong flats where your living room, dining room, and front door are the same 200 sq ft. Local storage means no monthly ransom, and face recognition that doesn't flag your cat as an intruder. HKD 1,398 at Fortress or HKTVmall.
Most security cameras make you choose between a wide shot (useless detail) or zoom (useless context). The S350 records both at once. The 2K wide feed covers the room; the 3K telephoto locks onto whoever just walked in. In a 350 sq ft studio, that's the difference between "someone's home" and "the helper forgot to lock the gate again."
Face recognition actually learns. Tag your family once, and it stops sending alerts every time your wife walks past. The 8GB onboard storage holds roughly 30 days of motion clips — no cloud subscription, no monthly HKD 68 disappearing into Google's pocket. Setup is scanning a QR code. It works with Alexa and Google Home, but you don't need either.
The only catch is size. It's bulkier than a Nest Cam (12cm tall), which matters if you're mounting it on a narrow shelf. And the app — Eufy Security — is functional but graceless. You'll find the clip you want; you won't enjoy the process.
Pros
- Dual lenses cover wide + detail simultaneously
- Local storage, zero subscription fees
- Face recognition that improves over time
- Works across Alexa, Google, Apple platforms
Cons
- Larger footprint than single-lens competitors
- App UI feels like an afterthought

2. Aqara G3 — For the HomeKit faithful
If you already live in Apple's walled garden, the G3 is the only camera here with native HomeKit Secure Video support — meaning end-to-end encryption and face recognition that runs on your HomePod, not Aqara's servers. It doubles as a Zigbee hub for Aqara sensors, which matters if you're building out a smart flat. HKD 1,598 at Broadway.
The G3 is narrower than it looks (110° FOV), so it works better aimed at a door than trying to cover a whole room. Image quality is sharp — 2K at 30fps, upgraded night vision that doesn't wash out faces under your ceiling light. The built-in infrared sensor can trigger automations (lights on when you walk in), but only if you own other Aqara gear.
HomeKit Secure Video stores clips in iCloud, which eats your 200GB plan faster than you'd think (10 days of motion = roughly 40GB). You can bypass it with a microSD card, but then you lose the HomeKit integration. The Aqara app works fine; it's just slower to load than Eufy's. Two-way audio has a half-second lag, which makes conversations with the delivery guy feel like a bad Zoom call.
Worth it if your flat already runs on HomeKit and you'd rather not juggle apps. Not worth it if you're platform-agnostic — the Eufy S350 does more for HKD 200 less.
Pros
- Native HomeKit Secure Video (end-to-end encrypted)
- Doubles as Zigbee hub for Aqara sensors
- Excellent night vision (colour mode under low light)
- Physical privacy shutter
Cons
- 110° FOV too narrow for most HK living rooms
- iCloud storage fills up fast with HKSV enabled
- Audio lag in two-way calls
| Resolution | 2K (2304 × 1296) |
| Field of View | 110° diagonal |
| Storage | microSD (up to 512GB) or iCloud via HKSV |
| Night Vision | Infrared + full-colour low-light mode |
| Audio | Two-way with echo cancellation |
| Smart Features | Face/gesture recognition, HomeKit automations |
| Zigbee Hub | Built-in (supports 128 devices) |
| Dimensions | 87mm H × 78mm W |
3. TP-Link Tapo C225 — The budget option that doesn't embarrass itself
HKD 398 at Fortress buys you 2K resolution, 360° pan/tilt, and motion tracking that follows your toddler (or your cat) around the room. The Tapo app is cleaner than TP-Link's router software, which is damning with faint praise, but it works. No face recognition, no local AI — just a camera that records when something moves and doesn't cost more than your monthly electricity bill.
The C225 is plasticky. It feels cheap because it is cheap. But the motor is smooth, the 2K sensor is identical to cameras twice the price, and setup is faster than the Eufy (90 seconds vs. three minutes). Motion tracking works well enough — it'll follow a person across the room, though it sometimes gets confused by ceiling fan shadows.
Storage is microSD only, capped at 128GB (roughly 20 days of motion clips at default settings). TP-Link offers cloud storage, but it's HKD 48/month and the value proposition is unclear when you can just buy a bigger card. Night vision is standard infrared — black-and-white, washes out at close range, fine for "is someone in my flat" but not "what's their face look like."
No smart home integration beyond Alexa and Google Assistant (no HomeKit, no Aqara). If you want a camera to check on the flat while you're at work and don't care about ecosystem lock-in, this is HKD 1,000 cheaper than the Eufy and does 80% of the job.
Pros
- HKD 398 — cheapest 2K camera that isn't junk
- 360° motorised pan/tilt covers full room
- Motion tracking follows moving subjects
- Tapo app is faster than most competitors
Cons
- Feels cheap (because it is)
- No face recognition or smart detection
- microSD capped at 128GB
| Resolution | 2K (2560 × 1440) |
| Field of View | 360° pan / 149° tilt |
| Storage | microSD (up to 128GB) |
| Night Vision | Infrared (up to 9m) |
| Audio | Two-way |
| Smart Features | Motion tracking, activity zones |
| Power | USB (cable + adapter included) |
| Dimensions | 86mm H × 78mm W |
4. Reolink E1 Zoom — When you need actual zoom, not digital crop
The E1 Zoom has a 5x optical zoom lens — the only camera here that can identify a face across a 500 sq ft space without pixelating into Minecraft. It's overkill for a studio, perfect for a village house or a flat with a long hallway. PoE support means one cable for power and data, which matters if you're mounting it outdoors. HKD 698 at HKTVmall.
Optical zoom changes everything. The E1 Zoom can sit in a corner and still read a license plate (or the label on a parcel someone left at your gate). The 5MP sensor holds detail through the zoom range; digital cameras just crop and pray. Pan-tilt is 355° horizontal, 50° vertical — enough to cover a balcony or car park.
Reolink's ecosystem is built for multi-camera setups. The E1 Zoom works standalone, but it's designed to feed into an NVR (network video recorder). If you're only buying one camera, the NVR is overkill. If you're covering three angles, it's HKD 1,200 for 1TB of storage and no subscription. The app is dense — too many menus, too much jargon — but powerful once you learn it.
Night vision is good (15m infrared range), but the camera can't see through window glare like the Eufy's spotlight mode. Audio is one-way only (you can hear, they can't hear you). And it's IP66-rated for outdoor use, which means it'll survive a typhoon but looks industrial mounted indoors.
Pros
- 5x optical zoom — actual zoom, not digital crop
- PoE support (one cable for power + data)
- Works with Reolink NVR for local multi-camera recording
- IP66 weatherproof (outdoor-ready)
Cons
- App is cluttered and jargon-heavy
- One-way audio only
- Looks too industrial for most living rooms
| Resolution | 5MP (2560 × 1920) |
| Field of View | 355° pan / 50° tilt |
| Zoom | 5x optical |
| Storage | microSD (up to 256GB) or Reolink NVR |
| Night Vision | Infrared (up to 15m) |
| Audio | One-way (camera to app only) |
| Power | PoE or 12V DC adapter |
| Weather Rating | IP66 (dust/waterproof) |
5. Google Nest Cam (Indoor) — For the subscription-tolerant
The Nest Cam is the only camera here that requires a subscription to unlock features you'd expect for free (face recognition, activity zones, more than three hours of cloud clips). If you already pay for Google One and own a Nest Hub, it's HKD 1,280 at Fortress and integrates seamlessly. If you don't, it's a worse deal than the Eufy S350.
Image quality is excellent — 1080p HDR with better dynamic range than the 2K competition. The camera adjusts exposure in real time, so backlit windows don't turn faces into silhouettes. Night vision is colour (using ambient light from streetlamps or your hallway), not infrared. The magnetic mount is the best in this category — snap it on, adjust the angle, done.
The catch is Nest Aware. Without a subscription (HKD 68/month or HKD 680/year), you get three hours of rolling cloud storage. That's it. No face recognition. No activity zones. No intelligent alerts. The camera becomes a live feed you can check manually — fine for "is the helper home yet," pointless for security. A 128GB microSD card costs HKD 120 and holds weeks of footage. Google's asking you to pay HKD 680 annually for features Eufy includes for free.
If you're deep in the Google ecosystem (Nest thermostat, Nest Hub, Google WiFi), the integration is worth something. The camera shows up in Google Home, streams to Nest Hub Max, triggers routines. Outside that context, it's a HKD 1,280 camera that costs another HKD 680/year to be useful.
Pros
- Best-in-class HDR image quality
- Colour night vision (no infrared wash)
- Magnetic mount is effortless
- Deep Google Home / Nest Hub integration
Cons
- Requires Nest Aware subscription for useful features
- Only 3 hours of free cloud storage (unusable for security)
- No local storage option
| Resolution | 1080p HDR |
| Field of View | 130° diagonal |
| Storage | Cloud only (requires Nest Aware) |
| Night Vision | Colour (ambient light) + infrared fallback |
| Audio | Two-way with noise suppression |
| Smart Features | Face/package/pet detection (Nest Aware required) |
| Power | USB-C (cable + adapter included) |
| Dimensions | 83mm H × 83mm W |
6. Imou Ranger 2C — The helper-monitoring special
The Ranger 2C costs HKD 448 at HKTVmall and does one thing better than anything else here: scheduled privacy mode. Set it to disable recording during hours you're home, enable when you're at work. Useful if you want to check that the helper locked the door but don't want to surveil your own flat 24/7. Baby monitor mode auto-tracks movement and plays lullabies (genuinely, this exists).
It's a mid-tier pan-tilt camera with a few niche features. The 355° rotation is smooth; the lens is 1080p (fine, not great). Two-way audio works without the Aqara lag. The privacy shutter is physical — a plastic cover that rotates over the lens when you tap "privacy mode" in the app. More reassuring than a software toggle.
Cloud storage is free for 24 hours (rolling), then HKD 38/month for 7 days or HKD 68/month for 30 days. You can skip it with a microSD card (up to 256GB), but the app nags you to upgrade every time you open it. Smart detection (person vs. pet) is hit-or-miss — it flags moths as people during the summer. Activity zones help, but you'll still get false positives.
The Imou app is cluttered (10 tabs, half of them useless). Setup took four tries because the QR code scanner refused to focus. Once running, it's stable. If scheduled privacy mode solves a specific problem for you, HKD 448 is reasonable. If it doesn't, the Tapo C225 is simpler and HKD 50 cheaper.
Pros
- Scheduled privacy mode (auto-disable recording when home)
- Physical lens shutter for privacy
- Baby monitor mode with auto-tracking and lullabies
- 24 hours free cloud storage (rolling)
Cons
- App is cluttered and pushy about cloud subscriptions
- Smart detection flags false positives often
- Setup QR scanner is finicky
| Resolution | 1080p (1920 × 1080) |
| Field of View | 355° pan / 90° tilt |
| Storage | microSD (up to 256GB) + cloud (24hr free) |
| Night Vision | Infrared (up to 10m) |
| Audio | Two-way |
| Smart Features | Human detection, scheduled privacy, baby cry detection |
| Power | USB (cable + adapter included) |
| Dimensions | 88mm H × 88mm W |
7. Xiaomi 360° 2K Pro — For Mi ecosystem completionists
The Xiaomi 2K Pro costs HKD 528 at Yata or Mi Store and works best if you already own a Mi Router, Mi Air Purifier, and Mi Smart Bulbs. It integrates with the Mi Home app (which controls 300+ Xiaomi devices), supports Mi AI automations, and stores footage on microSD up to 256GB. Outside the Mi ecosystem, it's a generic pan-tilt camera that costs HKD 130 more than the Tapo C225 for negligible improvements.
Image quality is sharp — 2K at 20fps, better than the Imou, not as good as the Eufy. The 360° motor is fast (3 seconds to spin a full rotation), which makes the "patrol mode" feature actually useful — the camera pans through preset checkpoints every 10 minutes. Night vision is infrared, range is 10m, nothing special.
AI detection is Xiaomi's weakest link. It flags curtains moving in the breeze as "human detected." Activity zones reduce false positives, but you're still checking your phone twice a day to confirm that no, a pigeon did not break into your flat. Two-way audio has an echo unless you disable the speaker on one end (your phone or the camera, pick one).
The Mi Home app is either "everything in one place" or "a chaotic mess of unrelated devices," depending on how much Xiaomi gear you own. If you're already committed to the ecosystem, HKD 528 is fine. If you're starting fresh, buy the Tapo C225 and save HKD 130.
Pros
- Deep Mi Home integration (300+ device automations)
- Fast 360° patrol mode (3-second full rotation)
- 2K resolution at a mid-tier price
- microSD up to 256GB
Cons
- AI detection is wildly inaccurate
- Two-way audio has persistent echo
- Only worth it if you own other Mi devices
