The TP-Link VIGI C540-4G is an outdoor network camera designed for areas where traditional wired internet is unavailable, utilizing a Nano SIM card for 4G LTE connectivity. It captures video at a 4MP resolution with a 4mm lens and an F1.6 aperture, allowing it to maintain clear images even in low-light conditions. To ensure visibility throughout the night, the device uses a combination of infrared and white LEDs that reach up to 30 meters, providing either traditional night vision or full-color imagery. This camera offers extensive coverage through its pan and tilt capabilities, rotating up to 348° horizontally and 120° vertically. It integrates smart detection features that can distinguish between humans and vehicles, and it can alert you to specific events like line-crossing or the removal of an object. For communication, the built-in microphone and speaker enable two-way audio, while a microSD slot supporting up to 512 GB allows for local storage of recordings. Built to withstand the elements, the white housing is IP66 weatherproof and operates in temperatures ranging from -30 °C to 60 °C. The unit weighs 0.69 kg and can be powered via a 12V DC adapter or PoE 802.3at. It comes with mounting accessories and waterproof cable attachments, making it a practical choice for monitoring remote sites, construction zones, or large outdoor properties.
