Under Order 176, Hotel TV Screen Casting Is More Than User Experience: How to Achieve Compliance for Screen Casting Activity Auditing

In the past, hotels purchasing screen casting devices mainly focused on connectivity convenience, playback smoothness and compatibility with various mobile phones. With increasingly stringent cybersecurity regulations, screen casting systems must also address device permissions, session records and traceability for anomalies. In cases of accidental screen casting or unauthorized device connections, hotels that fail to trace the connection process will not only suffer poor guest experience, but also face greater difficulties during regulatory audits.

Effective October 1, 2026, Measures for the Supervision and Inspection of Cyberspace Security by Public Security Organs (MOPS Ministerial Order No.176) officially came into force. The new regulation prioritizes legally required recording and retention of user registration information and internet access logs, as well as cybersecurity protection measures during supervision inspections. Hotels should integrate screen casting management into their overall cybersecurity framework in accordance with network operation obligations and applicable laws, rather than merely verifying whether TVs support screen casting.

I. Why Hotel Screen Casting Cannot Be Judged by User Experience Alone

1. Successful casting without traceable connection records

Conventional screen casting solutions prioritize device discovery and video transmission. Without session logging, administrators may be unable to confirm which TV was connected, which terminal was used, and the session start and end time when abnormalities occur.

Article 7 of Order 176 mandates the recording and retention of user registration data and internet access logs as key inspection items. Hotels must verify the completeness and retrievability of relevant network records. Functional screen casting alone does not equate to sound management.

2. Insufficient room isolation leads to accidental casting and unauthorized access

Mobile phones and TVs in hotel rooms may connect to the same wireless network. Improper configuration of device discovery scope and access policies may allow guests to view TVs in other rooms, triggering accidental casting and privacy leakage. Similar risks exist in corporate meeting rooms, where unauthorized terminals may connect to public displays and threaten internal data security.

Therefore, hotels need to control not only device connectivity, but also which terminals can discover which screens, who is authorized to initiate casting, and how to revoke device bindings after guest check-out.

3. Separated authentication and casting records hinder post-incident investigation

Some hotels have deployed Wi-Fi real-name authentication, yet authentication platforms, network gateways and screen casting systems store records independently with no correlation. Even if user authentication information is retrieved, matching screen casting sessions may remain untraceable.

Effective management links network access, device binding and screen casting sessions, enabling audits based on timestamp, terminal and room information once incidents emerge.

II. AINOPOL Screen Casting Reflector: Making Screen Casting Manageable and Traceable

1. Record screen casting sessions and support audit retention

AINOPOL Screen Casting Reflector operates as a built-in software module for the Dream Gateway ZH-M1, integrating screen casting management with gateway capabilities. The system records session data including sender endpoint, display endpoint, casting protocol type, start time, end time and data volume. Records are stored in structured local storage and retained for 180 days by default.

Administrators can review basic screen casting connection logs for anomaly troubleshooting. Hotels should regularly verify continuous log generation, historical data retrievability and storage capacity to prevent record loss caused by hardware failures or log overwriting.

2. Bind rooms and devices to reduce accidental casting and unauthorized connections

The AINOPOL Screen Casting Reflector supports room-level casting binding and display device approval. Configurable restrictions limit the scope of TV discovery and connection by mobile phones to prevent cross-room accidental casting. Hotels may manage bindings in alignment with check-in and check-out workflows and revoke permissions promptly upon guest departure.

For meeting room scenarios, casting permissions can be planned by zone and authorized terminals to block access from unvetted devices.

To associate casting sessions with specific guests, real-name authentication records and valid device bindings are required. Device names or MAC addresses alone cannot directly identify the actual operator and need cross-reference with supplementary audit data.

3. Unified access management and security auditing

Separated deployment for screen casting, Wi-Fi authentication and cybersecurity protection often results in fragmented maintenance and disconnected records.

AINOPOL Dream Series Secure Optical Gateways consolidate network access management, authentication, log auditing and security protection, working in tandem with the Screen Casting Reflector. Hotels can configure interfaces or VLANs according to network environments to centrally manage screen casting services and network access.

After deployment, validate compatibility across TVs and mobile phones, and verify device discovery, room isolation, log generation and permission revocation. The system must deliver reliable functionality while supporting long-term O&M.

4. Full-optical network and Integrated Communication & Security underpin overall cybersecurity

Hotel networks typically carry guest-room Wi-Fi, TV screen casting, surveillance, access control and office services. AINOPOL leverages full-optical architecture to plan access links and service boundaries, reducing active devices at the access layer and improving scalability and O&M flexibility.

Built on the coordinated authentication and logging capabilities of AINOPOL Dream Series Secure Optical Gateways, AINOPOL builds the native integrated “Communication & Security” solution with full-optical infrastructure as the foundation, audio & video services as the engine, and security as the protective shield. It helps hotels orchestrate audio & video services, data transmission and security management. The full-optical network provides transmission infrastructure; Dream Gateways handle access control and auditing; the Screen Casting Reflector manages casting sessions and devices. All capabilities work in synergy.

After Order 176 takes effect, hotels must attach greater importance to network access, log management and security protection. Although screen casting improves guest experience, it requires controls over device permissions, connection logs and anomaly traceability once running on hotel networks.

Combined with Dream Gateways, full-optical networks and the Integrated Communication & Security solution, the AINOPOL Screen Casting Reflector helps hotels complete screen casting session logging, room-level device management and cybersecurity O&M.

Screen casting systems should not only deliver easy connectivity, but also feature clear permissions, complete records and retrievable anomalies. Integrating screen casting into routine network management enables hotels to preserve guest experience while elevating network security governance.

FAQ

Q: If VLANs are not bridged, how can mobile phones discover TVs?
A: The reflector runs application-layer proxy inside the gateway. When TVs inside the TV network send mDNS/SSDP announcements, the reflector captures and registers these messages. When mobile phones on the guest network send casting queries, the reflector matches devices based on room binding rules and replies via unicast, rewriting the real IP and port to the gateway proxy address. The “in-room TV” seen by the mobile phone is actually the gateway proxy address.

Internet access behaviors can be filtered separately or combined and exported as complete compliance reports.

Q: If screen casting bindings are not unbound after guest check-out, are logs still retrievable?
A: Yes. Bindings automatically expire within 24 hours and become invalid after check-out. However, screen casting session logs remain fully preserved, recording when casting occurred, how long it lasted, and which room and authenticated account it was associated with. Log records and binding relationships are two separate dimensions; bindings expire, but log records will not be deleted accordingly.

Q: What issues related to screen casting logs can public security remote detection identify under Order 176?
A: Public security authorities use vulnerability scanning and penetration testing to remotely verify whether the screen casting system operates normally, whether log retention periods meet regulatory requirements, and whether log fields are complete. Inspectors generally request full screen casting records for the past six months. Non-compliance will be flagged directly if logs are retained for less than six months or contain missing fields.
