Vivotek: Troubleshooting Delayed Push Notifications
A timely notification is the cornerstone of effective video surveillance. When your Vivotek camera detects an event, you need to know about it instantly. A delay between the event and the push notification on your device can compromise your ability to respond effectively. If you're experiencing a noticeable lag, this guide will help you diagnose and resolve the issue.
Understanding the Notification Pathway
To fix delays, we must first understand the journey a notification takes. It's not a single step, and a delay can occur at any point:
- Detection: The Vivotek camera's analytics detect an event.
- Processing & Upload: The camera processes the event and sends the data to a server. This step is highly dependent on your local network's speed and stability.
- Push Service: The server instructs a push notification service (Apple or Google) to send an alert.
- Delivery: The service delivers the alert to your smartphone via the internet.
- Display: Your Vivotek app (like iViewer) receives and displays the notification.
The most common bottlenecks occur during the Processing & Upload stage (your network) and the Delivery stage (internet conditions).
How to Fix Vivotek Notification Delays
Work through these steps methodically to identify and solve the problem. You will need to access your Vivotek camera's web browser interface for some of these settings.
1. Verify Network Strength and Stability
Your camera's connection to your network is the most likely source of delays.
- Check Wi-Fi Signal (for wireless cameras): If your camera uses Wi-Fi, the signal must be strong and stable. Log in to your camera's web interface and check its network status. If the signal quality is low, the camera will struggle to send data quickly. Consider moving the camera closer to the router or using a Wi-Fi extender.
- Test Network Latency: Use a computer on the same network to "ping" the camera's IP address. Open a command prompt or terminal and type
ping [camera's IP address]. The time should consistently be low (ideally less than 20ms). High or fluctuating ping times indicate a problem with your local network. - Reduce Network Congestion: If other devices on your network are using a lot of bandwidth (e.g., streaming 4K video, large downloads), it can slow down your camera's ability to upload data. Try pausing these activities to see if notification speed improves.
2. Synchronise Camera Time Settings
Accurate timekeeping is crucial for event logging and notification. If your camera's clock is out of sync, it can cause processing delays.
- Access Date & Time Settings: In the camera's web interface, navigate to System → Date & Time.
- Use an NTP Server: Do not set the time manually. Select the option to Synchronise with NTP server. NTP (Network Time Protocol) automatically keeps your camera's internal clock perfectly accurate. Use a common server like
pool.ntp.orgor one specific to your region.
3. Optimise Video Stream Settings
The amount of data the camera has to process and send for an event can affect speed.
- Adjust Sub-stream Settings: For alerts, the camera often sends a clip from a secondary, lower-quality stream (sub-stream). In the Video → Stream settings, try slightly lowering the resolution or bitrate of the sub-stream. This creates a smaller file that can be uploaded faster, resulting in a quicker notification.
4. Update All Software Components
Running the latest software ensures you have all available performance improvements and bug fixes.
- Update Camera Firmware: Check the Vivotek website for the latest firmware for your specific camera model. Follow the instructions to update it via the web interface in the System → Maintenance section.
- Update Your Vivotek App: Go to the app store on your smartphone and ensure you have the newest version of the Vivotek iViewer or other management software you use.
By systematically checking your network's health, ensuring accurate time synchronisation, and keeping your system updated, you can significantly minimise latency and restore the real-time alerting capabilities of your Vivotek security system.
