Alarm Environment Setting Setting Chattering Guard Time of Alarm Input for VN-700 Format Example /api/param?peripheral. input_pin. pin(Number). chatter=data When setting the chattering guard time for alarm input 1 /api/param?peripheral. input_pin. pin(1). chatter=150 peripheral. input_pin. pin(1). chatter&200 OK Change the time setting to prevent chattering in the alarm input. Specify a number between 1 to 4 as VN-700 has 4 alarm inputs. admin, operator Example of response Interpretation Allowed users Acquiring Alarm Output Time Setting from VN-700 Format Example of Response Interpretation /api/param?peripheral. output_pin. pin. duration peripheral. output_pin. pin. duration=1000&200 OK Acquire the current alarm output duration in millisecond. If alarm output is set in alarm action, this parameter can be acqurired by following API. /api/param?application. event(Number). action admin, operator, user Allowed users Setting Alarm Output Time for VN-700 Format Example Example of response Interpretation /api/param?peripheral. input_pin. pin. duration=data /api/param?peripheral. input_pin. pin. duration=50 peripheral. input_pin. pin. duration&200 OK Change the alarm output duration in millisecond. Following API is also available to set the parameter. /api/param?application. event(Number). action admin, operator Allowed users Acquiring Alarm Output Status from VN-700 Format Example of Response Interpretation Allowed users /api/param?peripheral. output_pin. pin. status peripheral. output_pin. pin. status=make&200 OK Acquire the current alarm output status. admin, operator, user Changing Alarm Output of VN-700 Format Example Example of Response Interpretation /api/param?peripheral. output_pin. pin. status=data /api/param?peripheral. output_pin. pin. status=break peripheral. output_pin. pin. status&200 OK Change the alarm output. When the alarm output time is zero, alarm output is changed as this API specifies. When the alarm output time is not zero, alarm output is changed as this API specifies, then alarm output is changed again after the alarm output time. VN-700 enables motion detect to be adjusted for each of the 4 video inputs. Specify a value between 1 to 4 for the number. A value between 0 to 100 will be returned. The larger the value, the easier it will be to detect objects moving at high speed. The smaller the value, the easier it will be to detect slow-moving objects. admin, operator, user Example of response Interpretation Allowed users Setting Motion Parameters of Motion Detect for VN-700 Format Example /api/param?video. input(Number). detection. velocity=data When setting motion parameters of motion detect for video input channel 1 /api/param?video. input(1). detection. velocity=10 video. input(1). detection. velocity&200 OK Change the motion parameters of motion detect. VN-700 enables motion detect to be adjusted for each of the 4 video inputs. Specify a value between 1 to 4 for the number. The larger the value, the easier it will be to detect objects moving at high speed. The smaller the value, the easier it will be to detect slow-moving objects. admin, operator Example of response Interpretation Allowed users Acquiring Motion Detect Mask from VN-700 Format Example /api/param?video. input(Number). detection. area When acquiring the motion detect mask of video input channel 1 /api/param?video. input(1). detection. area video. input(1). detection. area=000102030405060708091011121314151617&200 OK Acquire the mask of motion detect. [. . . ] Multicast uses UDP and Ack does not exist. As such, the sender will be able to continue sending without being affected by network delays. 76 11.
