（1）Excessive RTSP connections or high encoding bit rate may cause overload and lead to the encoder not working ;
（2）Frequent signal loss may also lead to the encoder not working;
（3）The encoder working temperature is -20 ℃ to 60 ℃. Inappropriate working temperature may lead to the encoder not working.
（4）In poor network environment, as the decoder uses RTP over TCP to connect the encoder, repeated network transmission may lead to the network throughput overload and encoder not working.
