The C3A 1080p Outdoor Wi-Fi Camera 2-Pack with W2D Base Station Kit from ezviz includes two C3A cameras, along with a W2D base station. The cameras use a 1/4" 2MP image sensor to capture 1920 x 1080 resolution video at up to 30 fps. They have a night vision range up to 25'. The cameras each have a 2.2mm fixed lens with a 126° diagonal field of view. A PIR sensor will send an instant alert when it detects human or pet movement, while filtering out potential false motion alerts from insects, curtains, or lighting. Two-way audio communication is possible thanks to a built-in speaker and omnidirectional microphone. An onboard memory card slot supports microSD cards up to 128GB (available separately). The EZVIZ app for iOS and Android enables remote viewing and instant alerts. These battery-powered Wi-Fi cameras are housed in IP65-rated enclosures that are suitable for outdoor use. The W2D base station supports up to six C3A cameras and prolongs the battery life of connected cameras. This base station is equipped with a 100 dB siren. Hassle-Free, Effortless Security Use the C3A to monitor anywhere - whether indoors or outdoors or even in places without power outlets. Thanks to its wireless, battery powered and weatherproof design, the options are limitless! Watches over What Matters Most The C3A lets you see wide-angle, Full HD images. Its night vision also ensures 24/7 protection even when it's dark outside. Easy Two-Way Talk Speak with visitors and hear what's happening anywhere and at any time using your smartphone. Extra Protection with Accurate Detection The C3A's passive infrared (PIR) motion detection feature sends you an instant alert with images and videos captured when a visitor approaches. Once you connect the C3A with the W2D, the W2D will even emit a 100-decibel siren when triggered, reminding you to check on what's happening. Worry Less with Longer Battery Life The C3A equips with a removable and rechargeable 5,500 mAh Lithium battery. Paired with the W2D, the C3A's battery life can last even longer. With one-click sync buttons, the C3A and W2D will pair in seconds. Multiple Storage Solutions Save your recordings with flexible and secured solutions.
