Using the Hanwha ARN - 810S is a breeze. First, connect your cameras to the recorder, making sure to follow the input channel limits. You can then use the user - friendly interface on your preferred web browser or operating system to set up the camera parameters, such as IP address, bitrate, and compression. To start recording, simply configure the recording mode according to your needs, like continuous recording or event - triggered recording. When it comes to playback, you can search for footage by date, time, or event. Use the fast/slow forward and backward controls to quickly find what you're looking for. For maintenance, keep the device in a cool and dry place. Regularly check the HDD to ensure there's enough space for recording. If you encounter any issues, you can refer to the user manual or contact Hanwha support. Remember to update the firmware regularly to keep the device secure and functioning optimally.
