Controlling and Monitoring
By entering http requests in your browser’s URL field, you can:
• drive the relay output high or low
• monitor the status of the 4 digital inputs
This requires you to have root access to the AXIS 2460 and consequently, to supply a user
name and password. Login as root and supply the root password (default = pass).
Tip!
Relay Output
You can use the supported relay output to directly drive a maximum load of 24V AC/DC at
100mA. By connecting additional relay circuitry, it can also drive heavier loads.
The output relay is controlled using http requests, as defined in the following examples:
Example 1: - Set output 1 ON.
Example 2: - Set two 300ms pulses with 500ms delay between the pulses on output 1.
Example 3: - Wait 1 second before setting output 1 ON.
Digital Inputs
Four digital inputs allow the AXIS 2460 to be configured for time and alarm based image
recording. For example, by connecting a motion detector to a digital input, it is a relatively
simple procedure to send a single image (or video stream) to a remote imaging library each
time the detector is activated. These inputs can be driven by voltages of 5-24V.
Querying the Status of Digital Inputs
The status of the four supported digital inputs can be queried in exactly the same way as
the relay output. Simply enter the following URL to query the status of the digital inputs:
Example: - Monitor data on input ports 1, 2, 3, and 4.
Developers wishing to create applications incorporating sophisticated alarm conditioning using the
relay output and digital inputs are encouraged to read the Camera API, HTTP-Interface Specification,
