Python Script: Query Cameras
#!/usr/bin/env python3
import subprocess
import json
import sys
def get_camera_info(endpoint, username, password):
"""Get camera information using onvif-cli"""
cmd = [
"onvif-cli",
"-e", endpoint,
"-u", username,
"-p", password,
"-op", "info"
]
try:
result = subprocess.run(cmd, capture_output=True, text=True, timeout=30)
return result.stdout
except subprocess.TimeoutExpired:
return None
def get_stream_uri(endpoint, username, password):
"""Get RTSP stream URL"""

Error Handling
#!/bin/bash
onvif-cli -e http://192.168.1.100/onvif/device_service \
-u admin -p password \
-op info
if [ $? -eq 0 ]; then
echo "✅ Camera info retrieved successfully"
else
echo "❌ Failed to get camera info"
exit 1
fi
Tips & Best Practices
1. Use Environment Variables for Credentials
export CAMERA_IP="192.168.1.100"
export CAMERA_USER="admin"
export CAMERA_PASS="mypassword"
onvif-cli -e "http://$CAMERA_IP/onvif/device_service" \
-u "$CAMERA_USER" -p "$CAMERA_PASS" \
-op profiles
2. Batch Processing with Timeout
# Set a timeout for each operation
timeout 10 onvif-cli -e http://192.168.1.100/onvif/device_service \
-u admin -p password \
-op info
3. Logging Output
# Log to file with timestamp
{
echo "=== $(date) ==="
onvif-cli -e http://192.168.1.100/onvif/device_service \
-u admin -p password \
-op capabilities
} >> camera_query.log
4. Discovery with Interface Selection
# First list available interfaces
./onvif-cli -h # Shows help
# Then discover on specific interface
onvif-cli -op discover -i eth0
# Or by IP
onvif-cli -op discover -i 192.168.1.0
5. Handling Errors in Scripts
#!/bin/bash
check_camera() {
local endpoint="$1"
local user="$2"
local pass="$3"
if onvif-cli -e "$endpoint" -u "$user" -p "$pass" -op info &>/dev/null; then
echo "✅ Camera responsive"
return 0
else
echo "❌ Camera not responsive"
return 1
fi
}
# Check multiple cameras
for i in {1..5}; do
check_camera "http://192.168.1.$((100+i))/onvif/device_service" \
"admin" "password"
done
Comparison: Interactive vs Non-Interactive
| Aspect | Interactive | Non-Interactive |
|---|---|---|
| User prompts | Yes | No |
| Automation | Poor | Excellent |
| Scripts | Not suitable | Perfect |
| Docker/CI | Difficult | Ideal |
| Learning curve | Easy | Medium |
| Speed | Slow | Fast |
Troubleshooting
Problem: "Connection refused"
# Check if endpoint is reachable
curl -I http://192.168.1.100/onvif/device_service
# Try with explicit timeout
onvif-cli -e http://192.168.1.100/onvif/device_service \
-u admin -p password \
-op info \
-t 60
Problem: "Invalid credentials"
# Verify username and password
# Try interactive mode first to test credentials
./onvif-cli
# Then use correct credentials in non-interactive mode
onvif-cli -e http://192.168.1.100/onvif/device_service \
-u admin -p correctpassword \
-op info
Problem: Discovery finds no cameras
# List available interfaces first
./onvif-cli -h
# Try specific interface
onvif-cli -op discover -i eth0 -t 10
# Try different interface
onvif-cli -op discover -i wlan0 -t 10
Advanced: Creating Aliases
# Add to ~/.bashrc or ~/.zshrc
alias camera-info='onvif-cli -e http://192.168.1.100/onvif/device_service -u admin -p password -op info'
alias camera-stream='onvif-cli -e http://192.168.1.100/onvif/device_service -u admin -p password -op stream'
alias discover-cameras='onvif-cli -op discover -t 5'
# Usage
camera-info
camera-stream
discover-cameras
API Integration
In Go Programs
package main
import (
"os/exec"
"strings"
)
func getCameraInfo(endpoint, username, password string) (string, error) {
cmd := exec.Command("onvif-cli",
"-e", endpoint,
"-u", username,
"-p", password,
"-op", "info")
output, err := cmd.CombinedOutput()
return string(output), err
}
Summary
Non-interactive mode makes onvif-cli suitable for:
- ✅ Automation and scripting
- ✅ Docker containers
- ✅ CI/CD pipelines
- ✅ Batch processing
- ✅ Integration with other tools
- ✅ Programmatic access
All while maintaining backward compatibility with the interactive mode!
