    摘要： A surveillance system including a battery camera and a gateway. The battery camera includes a battery configured to supply power to the battery camera, a camera module configured to capture a surveillance area, a connector configured to directly connect to the gateway, a network module configured to communicate with the gateway, and a processor configured to charge the battery through the connector. The processor transmits high-quality images through the connector when the connector is connected to the gateway and transmits low-quality images through the network module when the connector is disconnected from the gateway.
