Key factors to consider
Types and key features to compare
- Disguised everyday items: looks like a clock, power bank or picture frame. Pro: blends in. Con: usually fixed view and may have limited battery life.
- Mini magnetic cameras: tiny, flexible mounting and excellent for tight spots. Pro: easy to place. Con: small batteries and sometimes limited range.
- Smoke detector style and static WiFi units: mains powered, offer continuous monitoring and app access. Pro: 24/7 recording and remote viewing. Con: more obvious if not mounted correctly.
- Local storage only models: no app or WiFi, record to SD card and are simple and private. Pro: no subscriptions. Con: no remote live view or instant alerts.
Important specs to check before buying:
- Video resolution and frame rate (1080p / 30 fps minimum)
- Night vision capability and range
- Battery capacity and claimed operating hours if portable
- SD card support and loop recording capability
- WiFi band support (many only work on 2.4 GHz)
- Motion detection sensitivity and notification options
- Ability to record while charging for continuous monitoring
Where to buy and common mistakes to avoid
- Assuming cloud access is free; many services charge monthly fees
- Buying a WiFi camera without confirming it supports your router band
- Overlooking whether an SD card is included; many units require you to buy one separately
- Trusting exaggerated battery life claims without reading user feedback
- Placing a device in a location that violates local privacy or recording laws
- Ignoring app permissions and default passwords; many devices ship with generic credentials
Quick expert tips and a buying checklist
- Resolution: 1080p or better
- Power: mains for 24/7, at least 10 to 20 hours battery for portable use
- Storage: supports micro SD up to 64 or 128 GB and has loop recording
- Connectivity: 2.4 GHz WiFi only or local-only option clearly stated
- Features: motion alerts, night vision, ability to record while charging

Final Thoughts
Choose the form factor that best fits the space you need to monitor, prioritise reliable video quality, storage and secure connectivity, and test the device in situ before relying on it. For privacy and long-term value, favour units that offer local storage plus clear app control, and avoid devices that require compulsory paid cloud subscriptions unless you need remote continuous recording.
