These compact surveillance units measure just 2.8 x 2.8 x 1.6 inches and boast IP65 certification for protection against dust and moisture. Installation is simplified through battery operation—each device uses two AA lithium cells that can potentially function for two years based on motion detection frequency. The package includes necessary batteries, installation accessories, and a central Sync Module for wireless network integration. The devices capture high-definition 2K footage (2,560 × 1,440 pixels) with a 135-degree viewing angle, sufficiently broad to monitor entry points without frequent adjustments. Practical testing reveals crisp video quality capable of identifying facial features or vehicle plates at moderate ranges.
