Key Considerations

1

This camera supports both 4G LTE cellular networks and 2.4 GHz Wi-Fi. If Wi-Fi fails or isn’t available, the camera can switch to cellular to maintain remote access — a valuable feature for rural or off-grid locations.

2

With 4K resolution, the camera captures high-detail footage that can help you identify faces, license plates, and other crucial details. The built-in 100-lumen spotlight enhances color night vision, making security monitoring effective after dark.

3

The S330 camera rotates and tilts to follow movement across large outdoor areas. Its AI tracking can detect people and vehicles, helping ensure important motion events are captured without blind spots.

4

Powered by a 9,400 mAh battery and an included solar panel, this camera delivers “forever power” — meaning you can often keep it running indefinitely with adequate sunlight, reducing the need for frequent recharging.

5

A 32 GB microSD card is included for local video recording. The package also includes a nano SIM card with initial data, letting you get started without buying separate cellular service immediately.

With 4K ultra-HD resolution and a bright spotlight for night color, this camera captures crisp, detailed video day and night. Its AI tracking actively follows people or vehicles across its pan & tilt range, enhancing security coverage. This camera’s ability to use both 4G cellular and Wi-Fi ensures you’re not locked out of remote monitoring even if your Wi-Fi flutters or disappears — ideal for remote properties or mobile scenarios where network reliability varies.

These factors represent the most critical aspects that will impact your satisfaction with this product.

Can I leave 10 stars?

My home needs to be completely rebuilt after a fire last year and when they start I wanted a way to watch while I would be at work. No electricity at the home

Great camera. Recently caught someone trying to steal wiring from our construction site. There’s no power or WiFi at the site, so the 4g and solar power functions of this camera were a selling point. The live view and solar power work perfectly. Battery stays almost at 100 full time, even with cloudy days. The data plan that the SIM card (included) offers is affordable. All in all, very worth it - 250 bucks ended up saving us 1500 in the long run.
