Explanation of External I/O Circuit Diagram:
CAUTION!
• THE LOW VOLTAGE/CURRENT CIRCUITS AND HIGH VOLTAGE/ CURRENT
CIRCUITS ARE IN THE NETWORK CAMERA CIRCUIT. THE QUALIFIED ELECTRICIAN
SHOULD DO THE WIRING NOT BY YOURSELF. INCORRECT WIRING COULD
DAMAGE NWTWORK CAMERA. YOU COULD RECEIVE THE FATAL ELECTRIC
SHOCK.
• THE EXTERNAL I/O IS NOT CAPABLE OF CONNECTING DIRECTLY TO DEVICES
THAT REQUIRE LARGE AMOUNTS OF CURRENT. IN SOME CASES, A CUSTOM
INTERFACE CIRCUIT (CUSTOMER PROVIDED) MAY HAVE TO BE USED. SERIOUS
DAMAGE TO NETWORK CAMERA MAY RESULT IF A DEVICE IS CONNECTED TO THE

Features
The video and audio
codec is adopted in the
device.
The device utilizes H.264, MPEG4 and JPEG triple compression to
providing high quality images. Where H.264 and MPEG4 are standards
for video compression and JPEG is a standard for image compression.
The audio codec is defined as AMR for 3GPP and G.711 for RTSP
streaming.
The maximum numbers
of users access the
device simultaneously.
The maximum number of users is limited to 20. However, it also
depends on the total bandwidth accessed to this device from clients.
The maximum data throughput of the device is around 20~25Mbps for
UDP mode and 10Mbps for HTTP mode. Therefore, the actual number
of connected clients is varying by streaming mode, settings of
resolution, codec type, frame rate and bandwidth. Obviously, the
performance of the each connected client will slow down when many
users are logged on.
The device can be used
outdoors or not.
The device is not weatherproof. It needs to be equipped with a
weatherproof case for outdoors using. However, equipped with a
weatherproof case might disable the audio function of the device.
