RS-485 Support
The pin 7 & 8 of the I/O connectors are used for RS-485 data
transmission. You can connect a special featured device (such as
an external camera stand with rotation function) to meet you
needs. When the external device is connected, you can configure
the settings and control the device from the RS-485 window of
Web Configuration Utility.
Day & Night Feature
The camera equipped with a Day & Night CCD IR lens which
included 12 infrared LEDs to provide crystal clear images in real
time, even at night. In a dark low light situation, the camera
switches to deliver black & white images using its infrared LEDs,
making it the best choice for your outdoor application.
