B13 4K Wireless Hidden Spy Camera Mini Security Camera

【Truly Wireless – No Cables, No Limits】Unlike cheaper plug-in cameras that need constant power, our hidden camera is fully cordless. With a powerful built-in battery, it offers up to 10 days of use or 30 days of standby on a full charge—perfect for hassle-free, discreet indoor surveillance. 【Stable 2.4GHz WiFi Only & Local Storage Support】Engineered for long-range reliability, this camera supports only 2.4GHz WiFi to ensure better wall penetration and connectivity (not compatible with 5GHz). Supports SD cards up to 128GB with continuous loop recording. 【Smarter PIR Detection, Fewer False Alarms】Upgraded PIR motion detection delivers real-time alerts with greater accuracy—no annoying cooldown delays or frequent false triggers, unlike basic motion sensors. (Note: Video recorded without audio per Amazon policy.) 【Upgraded Stable Stand】We have designed much tougher stand for this small camera than other competitors. The contact surface is far greater than other cameras', provid
