4pcs Indoor Wireless Security Cameras — Motion Detection, 2.4G/5G WiFi, Baby Monitor, Color Night Vision, 2-Way Audio & Siren, Supports Cloud, Max 256G SD Storage, Alexa, 24/7 Surveillance

Equipped with Dual-Band WiFi, these wireless security cameras work with both 2.4GHz and 5GHz networks to deliver a more stable connection and smoother live streams. Whether placed indoors or outdoors, the cameras maintain reliable performance so you can stay connected from anywhere. Store footage locally by inserting a 256GB SD card (not provided) to record continuously for up to 3 weeks; the system will automatically overwrite the oldest files so the newest clips are always retained. For added redundancy, optional Cloud storage is available (subscription needed) to back up videos off-device. Advanced color night vision produces vivid, full-color nighttime images instead of the typical black-and-white output, giving you clear monitoring around the clock. Additional features include motion detection, two-way audio with an integrated siren, baby monitoring capability, Alexa compatibility, and continuous 24/7 video surveillance.
