With the most recent firmware, our Plug & Play Series recorders can allow for sending an HTTP command over the network to grab a snapshot (.jpg format) of a particular channel. Below is the syntax to send via a browser or third-party application:
http://username:password@ip.address.of.recorder/GetSnapshot/x
username: username of account for recorder
password: password of account for recorder
x: Camera/Channel number
For example, the command you would send to a recorder to grab a snapshot for Channel 2, with the recorder at IP address 192.168.1.200:
http://demo:1234@192.168.1.200/GetSnapshot/2
