Security cameras have become essential devices for every home and office. Not only do they help monitor your property, modern cameras also integrate AI facial recognition, smart motion detection, phone alerts, and cloud storage. The current market ranges from cheap WiFi cameras under 500K VND to professional IP systems costing tens of millions of VND.
This guide will help you choose the right security camera based on your actual needs — indoor monitoring, outdoor surveillance, balcony, or warehouse — without being overwhelmed by hundreds of options on the market.
What to Know When Buying a Security Camera
Six most important factors: resolution, night vision, field of view, connectivity, storage, and water resistance.
Resolution determines image detail. 1080p (2MP) is the minimum, 2K (4MP) is the current standard, and 4K (8MP) offers the highest quality. With 4K, you can read license plates from 15-20 meters away. However, higher resolution means more bandwidth and higher storage costs.
Night vision uses infrared (IR) or white LED lights. Infrared provides black-and-white images with a range of 10-30 meters. Full-Color Night Vision technology (with supplemental white LED lights) allows color recording even in total darkness — very useful for identification.
Field of View (FoV) commonly ranges from 90°-130°. A wider angle covers more area but may cause image distortion. Pan/tilt cameras can rotate horizontally and vertically, covering an entire room with just one camera.
Connectivity: WiFi cameras are easy to install but depend on WiFi signal. PoE (Power over Ethernet) cameras use network cables for both data and power — more stable but require wiring. 4G LTE cameras use a SIM card for locations without fixed internet.
Storage comes in three forms: microSD card (on-device, limited capacity), NVR/recorder (centralized, multi-channel), and cloud (safe but requires monthly fees).
Water resistance: outdoor cameras need IP65 or IP66 rating. Indoor cameras may only need IP54.

Comparison with Other Options
WiFi Camera vs PoE (Wired) Camera
WiFi cameras can be installed in 5 minutes and placed anywhere within signal range. However, they are prone to interference, disconnection, and hacking. PoE cameras offer absolute stability, no signal loss, and higher video quality thanks to full bandwidth. PoE is typically 30-50% more expensive and requires wiring, but provides superior reliability.
Security Camera vs Smart Doorbell
Security cameras are suitable for continuous area monitoring. Doorbell cameras specialize in front door surveillance with a microphone/speaker for two-way conversation. The ideal setup combines both: a doorbell for the front door and security cameras for the yard and interior.
NVR Camera System vs Individual Cameras
An NVR system allows centralized management, long-term storage on large hard drives (2-10TB), and typically offers higher reliability. Individual cameras are cheaper but have limited storage on memory cards and are harder to manage when you have many of them.
Common Mistakes When Buying
- Only caring about resolution — A 4K camera with a small sensor will produce worse images than a 2K camera with a large sensor in low-light conditions. Look at the whole picture, not just megapixels.
- Forgetting to check the video compression standard — H.265+ saves 50% bandwidth compared to H.264. A 4K camera using H.264 will consume massive amounts of storage.
- Buying an outdoor camera with insufficient IP rating — An IP54 camera placed outdoors will fail in the first rainy season. Buy IP66 for outdoor use.
- Not checking security — Cheap Chinese cameras may have security vulnerabilities. Choose reputable brands and change default passwords.
- Installing WiFi in a weak signal area — A WiFi camera 20 meters from the router through walls will disconnect constantly. Check signal strength before installing or use a mesh WiFi system.
- Not factoring in cloud storage costs — Many cameras (Eufy, Ring) have monthly cloud subscription fees. Calculate the total cost over 2-3 years.
Conclusion
Security cameras are one of the most worthwhile smart home investments. For basic indoor monitoring, the TP-Link Tapo C200 or Xiaomi C300 (300-500K VND) is a great starting point. If you need outdoor surveillance, the Eufy Outdoor Cam 2K (around 1.5-2.5 million VND) or Reolink RLC-810A (around 1.5 million VND) are reliable choices. For a professional system for offices/villas, invest in Hikvision or Dahua PoE cameras with an 8-channel NVR (10-20 million VND).
My advice: buy cameras from brands with a Vietnamese-localized app and local storage support. Cheap no-name cameras pose security risks and often fail after 6-12 months.
