Important notice: This is an older style analog camera — it is not wireless or WiFi and is not compatible with HD camera systems. It does not operate on its own and must be connected to traditional analog equipment such as a DVR (Digital Video Recorder), coax cable and a monitor (all sold separately). It can be used with legacy DVR systems (around 10 years old); if you are new to security cameras, this model is not recommended.

The advanced day/night function records color images in daylight and switches to black-and-white at night.

Night vision and sensitivity: 20 Infrared LEDs with a minimum illumination of 0.0 Lux (IR LED on). System and power: NTSC signal system. Power consumption is 12V DC 500mA (power adapters included). Connections: BNC video output and a 2.1 mm center-positive power plug. Package contents: 16 x security cameras, 16 x power adapters and free warning stickers.
