Overview

Cranes on construction sites are increasingly equipped with high-definition cameras to support operator visibility, load positioning, safety monitoring, and site-wide surveillance. These cameras stream real-time footage from the crane’s boom, hook, or cab to improve operational awareness and reduce the risk of accidents.

To make this camera footage useful, especially for on-ground supervisors and control room personnel, a reliable solution is needed to decode IP video streams into HDMI output for display on monitors. That’s where our ANT-36100 Video Decoder comes in.

The Challenge

Cameras mounted on cranes typically encode and stream video over IP networks using RTSP, RTP, or ONVIF protocols. However, on construction sites, network connections, especially Wi-Fi or wireless bridges, can be unstable and prone to packet loss, jitter, and fluctuations in bandwidth. These issues introduce latency drift, where the delay between camera capture and video display gradually increases.

This drift can lead to a dangerous mismatch between real-world events and the video shown on screen, especially in time-sensitive operations like lifting and placing loads. Operators and supervisors need real-time visibility, not footage that lags behind or freezes unexpectedly.

The Solution: ANT-36100 Video Decoder

The ANT-36100 is a professional-grade IP-to-HDMI video decoder that converts live camera streams into crystal-clear video output, even under fluctuating network conditions.Feat

• Supports RTSP, RTP, ONVIF, and other standard protocols

• Full HD 1080p60 HDMI output

• Low-latency decoding with jitter buffer

• Compact, industrial-grade design

• Auto-start, auto-reconnect, and watchdog timer for uninterrupted operation

• Built-in alarm for latency drift detection

Advanced Stability: Latency Drift Alarm & Network Resilience

The ANT-36100 includes an alarm system that triggers when video latency drifts beyond a defined threshold, ensuring that operations relying on timely video feeds can be alerted immediately. This feature is vital when used over Wi-Fi or temporary site networks, where bandwidth fluctuations or packet loss are common.

Instead of silently increasing the latency and misleading the operator with out-of-sync footage, the ANT-36100’s alarm allows site personnel to take corrective action, such as resetting the connection, switching networks, or pausing an operation until the feed is stabilised.

This capability is a critical safety and efficiency feature for environments where real-time video matters.

Benefits to Crane Operation and Site Management

1. Real-Time Visual Feedback for Crane Operators
   Low-latency, HDMI-output video from crane cameras helps operators work more safely and precisely, even in blind spots.

2. Supervisor Monitoring from Ground Level
   A second decoder can provide live visuals in a supervisor station or control cabin, aiding site-wide coordination.

3. Stable Viewing on Unreliable Networks
   The ANT-36100 performs reliably even over Wi-Fi, thanks to its buffering and latency alarm safeguards.

4. Plug-and-Play Compatibility
   No PC is required — the decoder connects directly to the IP stream and outputs HDMI, simplifying deployment.

Conclusion

With the ANT-36100, Antrica delivers a dependable and intelligent decoding solution for construction crane operations. By providing real-time visibility, latency monitoring, and robust performance on unstable networks, the ANT-36100 empowers operators and supervisors to make faster, safer decisions on site.
