What to know before buying
- The listed SIM-network information refers to US carriers in one feature, while the FAQ describes UK and EU 4G bands and says compatible 5G SIM cards operate at 4G. Confirm UK network and SIM suitability, and account for mobile-data charges.
- Battery guidance is conditional: the listing estimates about one month without added solar power, or indefinite operation with two hours of daily solar charging under optimal conditions. Actual results depend on sunlight and use.
- The listing says the camera works with HomeBase S380 over Wi-Fi, supports Alexa and Google Assistant, and does not support Apple HomeKit or NAS storage.
Listing details to confirm
Listing details are contradictory or inconsistent: it claims 4K video but also lists 1 MP still and rear-camera resolution and an effective video resolution of 2169.0. It describes 360 Degrees viewing, while the screen-size entry is 1 with no unit. It gives both Not Water Resistant and IP55. The connectivity feature claims automatic Wi-Fi-to-4G switching, but its FAQ says switching must be done manually. Confirm these details for the selected listing before buying. Listed data usage is around 700 MB per month for the specified pattern of ten daily 10-second live views and 25 daily 10-second motion recordings. Actual usage may differ.

Customer feedback reports positive impressions of video quality and ease of setup, while connectivity, motion detection, accuracy and battery life receive mixed responses.

Value opinions are also mixed.

Mixed feedback
- Feedback is mixed on connectivity, accuracy and motion detection, including reports of connectivity problems and poor facial recognition.
- Battery-life and value-for-money impressions vary.
Frequently asked questions
Does the S330 switch automatically between Wi-Fi and 4G?
The listing conflicts on this point. A feature claim says it switches automatically if Wi-Fi is lost, but the FAQ says connection mode must be changed manually in the app. Confirm the behaviour for the selected listing.
Can it operate without Wi-Fi?
The listing presents the camera as supporting 4G LTE as well as Wi-Fi. Mobile operation depends on compatible coverage, a suitable SIM and data plan. The supplied listing gives conflicting details about network switching.
How long does the battery last?
The listing estimates around one month without additional solar charging. It also claims that two hours of daily solar charging can maintain power indefinitely under optimal conditions. These are conditional manufacturer claims, not guaranteed runtimes.
Is the camera waterproof?
The listing gives conflicting protection details: it says Not Water Resistant in one field and lists IP55 elsewhere. Check the selected product information if weather exposure is important.
Does it work with Apple HomeKit or NAS storage?
The listing says it does not support Apple HomeKit or NAS storage. It says HomeBase S380 works when the camera is connected over Wi-Fi.
