You can install CCTV without home Wi-Fi. A SIM-based 4G camera is one option for remote viewing. Ethernet or PoE may suit a site with cable access. Some cameras can record locally without an internet connection after suitable setup, but remote viewing, notifications and initial configuration have separate requirements. In Hong Kong village houses, parking spaces and renovation sites, check power and connectivity together.
Start with the site, then choose the camera
| Site conditions | Direction to consider | Check first |
|---|---|---|
| Power and broadband, weak Wi-Fi | Ethernet/PoE or improve network coverage | Cable route and compatible power equipment |
| Power but no broadband | An externally powered 4G camera | Safe power supply, SIM and signal |
| No socket and no broadband | 4G battery camera with a compatible solar option | Charging access, sunlight and recording mode |
| Local footage collection only | A model verified for offline local recording | Initial setup, clock and retrieval method |
Test the intended mobile network at the actual mounting position. A phone signal nearby is only an initial clue. Metal gates, concrete walls and underground car parks can change reception. Avoid assuming that a mobile hotspot will remain available when its owner leaves.
Store models worth comparing
| Model | Reason to compare | Suitable enquiry |
|---|---|---|
| EZVIZ H5 4G outdoor camera | LTE and wired-network options | A fixed position with available power |
| EZVIZ EB8 Pro 4G/Wi-Fi battery camera | Both cellular and Wi-Fi connectivity | A site where the network may change later |
| EZVIZ CB60 Dual 4G/Wi-Fi camera | Dual lenses and hybrid zoom | Overview plus closer inspection; hybrid zoom is not optical zoom |
| Reolink Go PT Ultra | Cellular connection and motorized movement | An outdoor site with a realistic charging plan |
These are feature-based starting points, not signal or battery-life test rankings. Compare the exact version in our security camera collection. Check the regional SKU, supported mobile bands, SIM requirements and carrier conditions before ordering.
Budget for connectivity and recording separately
A microSD card provides local storage. A data plan supports cellular communication. An optional cloud subscription has its own recording and retention conditions. Do not treat any one of these as a replacement for the other two. Check compatible storage and solar accessories against the full model name.
Also identify the recording mode. Event recording, pre-recording, AOV and ordinary continuous recording preserve different parts of the timeline. EZVIZ describes AOV as interval-based scene capture with event video. Read our guide to missing event beginnings on battery cameras if complete lead-in footage matters.
Frequently asked questions
Can I use a phone hotspot?
Potentially, if the camera and hotspot are compatible. Phone sleep, battery, departure and service conditions make this a different arrangement from a permanent network.
Does a 4G camera have no monthly cost?
SIM data usually has a separate cost, and cloud storage may be optional and separately charged. Local recording does not remove cellular service costs.
Should every village house use 4G?
Where stable power, broadband and cable routes exist, compare PoE as well. Our Hong Kong home CCTV guide explains the broader choices.
What to prepare before asking for a recommendation
Bring a photo of the mounting location, the available power source, the intended mobile network and the required recording history. Those details help narrow the choice more reliably than resolution alone.
