In general, 4G solar security cameras are ideal for remote areas, farms, and construction sites, while solar WiFi cameras are better suited for homes, driveways, and small businesses where WiFi is readily available.
1. Coverage & Installation Range: 4G vs WiFi Solar Security Cameras
4G Solar Security Camera Coverage
4G solar security cameras use a SIM card to connect to the 4G/LTE cellular network. You don’t need WiFi or a fixed internet line. You can install them anywhere with a cellular signal. This includes remote or off-grid areas, think farms, cabins, wildlife monitoring sites, and construction zones.
Solar WiFi Camera Coverage
Solar WiFi cameras need a stable 2.4GHz or 5GHz WiFi signal from your home or property router. Your WiFi router’s reach limits their installation range.
Typical WiFi camera range:
Indoors or with obstacles: I recommend staying 20–30 meters from the router for a stable connection.
Open outdoor spaces: Can reach up to 50–100 meters if unobstructed.
Walls, thick trees, and buildings reduce WiFi range significantly.
WiFi solar cameras work best near a reliable router. They suit homes, driveways, storefronts, or garages close to the main internet source.
2. Installation Process: 4G Solar Security Camera vs Solar WiFi Camera
Installing a 4G solar security camera differs from installing a solar WiFi camera. The main differences are network type and setup needs.
