SNMPv3: For data security reason, the authentication and encryption assurances are
added when developing SNMPv3. The user has to give not only the security name
(the same as "community name" in v1&v2c, or sometimes we call it "context name")
but the password in order to access the IP camera. Please set security name,
authentication type, authentication password, encryption type, encryption password of
write and read respectively. The password must be 8~64 bits in length. Different from
in SNMPv1 and v2c, the user have to create a account when using SNMPv3. In the
account parameters, key in the security name and password you set in the camera to
get accessing.
SNMPv1/v2cTrap: Trap is a mechanism that allows the managed device to send
messages to manager instead of waiting passively for polling from the manager.
Specify the trap event. When those events happen, the camera will send the ring
message to the Trap Address, which is usually the manager's IP address. Trap
Community means the community that can receive the trap message.
- Cold Start: The camera starts up or reboots.
- Setting changed: The SNMP setting is changed.
- Network Disconnected: The network connection was broken down. (The camera
will send trap messages after the network being connected again)
V3 Authentication Failed: A SNMPv3 user account tries to get authentication but
failed. (Due to incorrect password or community)
SD Insert / Remove: A microSD/SDHC card is inserted or removed.
