Thank you for viewing! I opened it to check the contents, but it's a brand new, unused item! It has been stored at home, but I would appreciate it if you could purchase it if you understand this. Product Description With a multi-layer lens set that incorporates an IR-CUT dual filter lens, you no longer have to worry about images turning red or purple. The built-in IR-CUT automatically switches according to the intensity of the external light, optimizing the image. Equipped with the latest Liteos sensor, it achieves a quick wake-up function. When infrared rays detect the movement of an object, the camera immediately wakes up to record and save, and after recording, it immediately enters a low-power hibernation mode, and at the same time, it realizes an intelligent low-power working mode, which significantly saves power and extends the recording time after a full charge, allowing you to record 15 hours of video. This small camera adds PIR human recognition function to motion detection, reducing invalid alarms through double filtration. Body size: A 3.4x3.4x4.3cm cube! It's a compact camera that's easy to hide and difficult to detect. Using 6 high-efficiency 940nm infrared LEDs, it automatically switches to infrared night vision when the surroundings of the webcam become dark, allowing you to clearly record and monitor the surroundings even in dim environments. Equipped with the new generation H.264+ video encoding technology, it significantly reduces the space occupied while improving image quality by up to 35% with H.264 video encoding technology. This compact surveillance camera allows remote operation and monitoring via Wi-Fi connection mode, and you can check what's happening within the camera's installation range from your smartphone, even in the office or while traveling.
