    • Day/Night Mode: true (Captures images/video with optimal clarity by automatically adjusting settings to various light levels.)
    • IP Camera: No (An Internet Protocol (IP) camera is able to record and display image/video data via the internet, without need for a local recording device.)
    • Minimum Required Illumination: 0 lux (Refers to the minimum amount of light needed to view objects. Generally, the lower the number, the better the camera can detect objects in little to no light.)
    • Number of IR LEDs: 48 (Quantity of infrared (IR) LED lights for emitting IR light and allowing the camera to detect objects in low light.)
    • Image Sensor Type: CDS (CCD and CMOS are the two main technologies used in image sensors. CCD, the older of the two types, turns analog light signals into digital pixels. This conversion happens without distortion, resulting in high-quality images. Newer CMOS sensors use transistors at each pixel to move electrical charges. CMOS sensors are typically less expensive, but also require more light to create distortion-free images.)
  • Compatibility
    • Camera Compatibility: Sentinel Pro 21146
    • Operating System Compatibility: Windows
  • Connectivity
    • Camera Connectivity: Wired (Security system cameras can be set up in several ways. Wired cameras require cables for power and footage transmission, while wire-free cameras don't need cables for either. Wireless cameras still require cables for receiving power but are able to transmit footage via a wireless network.)
