Tiandy 2MP 4-Camera System | Full HD SurveillanceKey Performance Features1080p Full HD Resolution: Captures video at $1920 times 1080$ resolution at 30fps. This provides crisp, smooth footage that is significantly clearer than standard analog cameras, allowing you to recognize faces and general activity with ease.Color Maker / Starlight Technology: Many of these kits feature Starlight sensors or Color Maker tech with an F1.6 or F1.0 aperture. This allows the cameras to maintain a color image in very low light, only switching to IR (black and white) or activating a soft white light in total darkness.Built-in Microphone: Unlike many entry-level kits, Tiandy cameras in this series usually feature an integrated microphone for one-way audio recording, giving you sound to match your video evidence.S+265 Video Compression: This advanced technology reduces the file size of your recordings by up to 75% compared to standard H.264. This means you can store more footage on a smaller hard drive without losing video quality.Plug-and-Play PoE: The cameras connect directly to the NVR (Network Video Recorder). There is no need for separate power adapters or complex network configurations; the system recognizes the cameras as soon as they are plugged in.
