This 4G cellular trail camera has a built-in 4G LTE module and supports 4G communication. Its infrared sensor (PIR) will detect moving objects, then capture a photo or video, save it to the SD card and send a notification to the mobile APP, and the photo or video can also be transmitted to the smartphone App through the 4G network. The trail camera offers cloud services, allowing photos and videos to be saved in the cloud and downloaded to your phone. Photos stored on the SD card have a 14MP resolution, while those uploaded to the cloud are in VGA resolution. It includes a free trial of the cloud service, with an in-app guide to help activate it. The camera supports live streaming for real-time viewing and remote control via your phone, making it convenient to use without being on-site.

Verdict

The call

The clearest difference is review sentiment: Ucon at 83% against Kdisk's 15%. Ucon also leads on rating (4.7 vs 1.6) and update cadence (every 3 weeks vs every 2 months). Kdisk's advantage is in-app purchases (none vs 23) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.
