Q1\uff1aAfter inserting the SIM card, cannot connect to the network, prompting “Adaptation unsuccessful” or “No network signal”?<\/strong><\/summary>\n

A1\uff1aCheck if the SIM card is inserted properly and if the carrier is compatible.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: The SIM card is not inserted correctly, has poor contact, or the SIM card carrier is incompatible with the device’s 4G\/5G module (e.g., some overseas modules only support specific regional carriers; confirm band compatibility for regions like US, Japan).<\/p>\n\n\n\n

Solution: Power off the device, reinsert the SIM card, ensuring the metal contacts face down and the notch aligns with the slot. If still no signal, try replacing with a SIM card from a local mainstream carrier (e.g., US: T-Mobile\/AT&T; Japan: Docomo\/SoftBank). Confirm the SIM card has an active data plan and sufficient balance. Note: Adaptation for Verizon carrier is not yet completed and is unsupported.<\/p>\n\n\n\n

A2\uff1aManually configure APN parameters.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: The device did not automatically obtain the carrier’s APN (Access Point Name), preventing network connection establishment, especially common with overseas carriers or special plan SIM cards.<\/p>\n\n\n\n

Solution: 1. Enter the device interface (LCD screen or Web backend), find “Network Settings -> 4G\/5G Settings”. 2. Turn off “Auto-obtain APN,” manually enter the APN provided by the carrier (e.g., China Mobile APN is “cmnet”; overseas, consult the local carrier). 3. If authentication is required, enter the “Username\/Password” provided by the carrier. Save and restart the 4G\/5G module.<\/p>\n\n\n\n

Q2\uff1aStreaming is normal during debugging, but bonding streaming is laggy, with delayed video at the event site?<\/strong><\/summary>\n

A1\uff1acheck the on-site network status and SIM card data balance.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Weak network signal at the event site (e.g., indoors, basement obstruction), exhausted SIM card data, or speed throttling can cause insufficient bonding link bandwidth. The device doesn’t directly display “signal strength dBm value,” but link stability can be inferred from “Uplink\/Downlink Rate” and “Latency ms” (Rate consistently below 1Mbps or Latency above 500ms usually indicates poor signal or insufficient bandwidth).<\/p>\n\n\n\n

Solution: 1. On the LCD screen “Bonding” interface, check the “Uplink Rate,” “Downlink Rate,” and “Latency ms” for each link (4G\/5G\/Wi-Fi): If a link’s rate is consistently below 1Mbps or latency above 500ms, click to “deselect” it from participating in bonding. 2. Contact the carrier to confirm if the SIM card is throttled\/out of data; replace with a local SIM card with strong signal and sufficient data if needed. 3. If wired network or stable Wi-Fi is available on-site, prioritize connecting to it and add it to the bonding link to improve stability.<\/p>\n\n\n\n

A2\uff1aCheck if the bonding buffer time matches the network jitter.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Buffer time is less than the on-site network jitter value, causing video lag due to discontinuous data transmission.<\/p>\n\n\n\n

Solution: Enter the Web backend “Bonding Settings.” If low latency is not critical (e.g., non-real-time interactive scenarios), adjust the buffer time to “500ms-1000ms” (recommended to be greater than the “Network Jitter” value displayed on the device). Save and restart the bonding stream.<\/p>\n\n\n\n

A3\uff1aConfirm if VBR is enabled, adjust encoding parameters as needed.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: If VBR is not enabled, fixed bitrate (CBR) is prone to lag during network fluctuations. If VBR is enabled but the maximum bitrate is set too high, it may still exceed the available bandwidth.<\/p>\n\n\n\n

Solution: 1. Enter “Encoding Settings,” enable “VBR” (prioritizes smoothness in weak network environments), and set a maximum bitrate limit (e.g., 8-10 Mbps for 1080P, 20-25 Mbps for 4K). 2. If the network environment cannot be improved, reduce the encoding resolution (e.g., 4K\u21921080P) or frame rate (60fps\u219230fps) to reduce bandwidth pressure.<\/p>\n<\/details>\n\n\n\n

Q3: What’s the difference between “Local Streaming” and “Bonding Streaming” in the device backend? When to use each? How to choose if problems occur?<\/strong><\/summary>\n

A1\uff1aclarify the core differences and applicable scenarios.<\/strong><\/p>\n\n\n\n

Type<\/strong><\/strong><\/td>Core Characteristics<\/strong><\/strong><\/td>Applicable Scenarios<\/strong><\/strong><\/td>Advantages \/ Disadvantages<\/strong><\/strong><\/td><\/tr>
Local Streaming<\/td>Streams directly from the device to the target platform (e.g., RTMP push).<\/td>Single scenario,stable network (e.g., fixed studio with wired network).<\/td>Advantages:Low latency, simple operation.
Disadvantages:Uses only a single link; prone to lag if the network fluctuates.<\/td><\/tr>
Bonding Streaming<\/td>Combines bandwidth from multiple links (4G\/5G\/Wi-Fi\/Wired) for streaming.<\/td>Mobile scenarios,weak network environments (e.g., outdoor live broadcast, event sites).<\/td>Advantages:Bandwidth aggregation, strong anti-interference.
Disadvantages:Requires KiloLink Server Pro; slightly higher latency.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

A2\uff1aCommon Problems and Selection Suggestions.<\/strong><\/p>\n\n\n\n

\u2022   Problem 1: Local streaming is laggy, bonding streaming is smoother?<\/p>\n\n\n\n

    \u25e6   Troubleshooting Reason: Local streaming uses a single link; bonding aggregates multiple links for more bandwidth.<\/p>\n\n\n\n

    \u25e6   Solution Suggestion: Prioritize using bonding streaming. Deselect links with poor signal. Ensure KiloLink Server Pro connection is normal.<\/p>\n\n\n\n

\u2022   Problem 2: Pursuing low latency, don’t want to use bonding?<\/p>\n\n\n\n

    \u25e6   Troubleshooting Reason: Bonding streaming has slightly higher latency than local streaming due to multi-link buffering.<\/p>\n\n\n\n

    \u25e6   Solution Suggestion: If the on-site network is stable (e.g., Gigabit wired), choose “Local Streaming” and disable VBR, use CBR fixed bitrate. If the network is fluctuating, still switch to bonding streaming and set the buffer time to “200-300ms” to balance latency and smoothness.<\/p>\n\n\n\n

\u2022   Problem 3: Local streaming works, but bonding cannot connect to the server?<\/p>\n\n\n\n

    \u25e6   Troubleshooting Reason: Incorrect server IP\/Port\/Authorization code for bonding, or port forwarding not configured.<\/p>\n\n\n\n

    \u25e6   Solution Suggestion: Verify the KiloLink Server Pro’s “IP\/Port\/Authorization Code” (re-enter in the device’s “Bonding Settings”). If the device is on an external network, configure “Port Forwarding” on the server’s router (forward the bonding port, default 50000).<\/p>\n<\/details>\n\n\n\n

Q4: After inserting SD card\/USB drive, local recording has no response, or recorded files cannot be played?<\/strong><\/summary>\n

A1\uff1aCheck if the storage device is compatible and properly inserted.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: SD card\/USB drive not inserted firmly, incompatible file system (e.g., NTFS not supported), or storage device damaged.<\/p>\n\n\n\n

Solution: 1. Power off and reinsert the SD card\/USB drive, ensuring it clicks into place. 2. Check in the Web backend “Recording -> Storage Device” if it is recognized. If not, replace with a storage device formatted as FAT32\/exFAT (recommended capacity \u2264256GB). 3. Test the storage device on a computer to see if it works normally; replace if damaged.<\/p>\n\n\n\n

A2\uff1aCheck if recording settings are correct, and if the device was removed after stopping recording.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: The “Record Switch” was not turned on, or the storage device was removed during recording, corrupting the file.<\/p>\n\n\n\n

Solution: 1. On the LCD screen, click the “Record” button (turns red when recording). Confirm the “Recording File Format” is set to MP4 (better compatibility). 2. After recording, first click “Stop Recording.” Wait for the “Safe to Remove” prompt before removing the SD card\/USB drive. 3. If the file cannot be played, use software like “Format Factory” on a computer to try to repair it, or re-record for testing.<\/p>\n<\/details>\n\n\n\n

Q5: P3\/P3-mini encoder output video is blurry, lacks detail, or shows compression artifacts?
<\/strong><\/summary>\n

A1\uff1aFirst, check if the encoding bitrate is too low.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Bitrate is the core factor affecting quality. Too low bitrate causes excessive compression, leading to blurriness and color blocks (e.g., 1080P video below 3 Mbps, 4K video below 15 Mbps are prone to blur).<\/p>\n\n\n\n

Solution: 1. Go to the device Web backend or LCD screen “Encoding Settings,” check the current bitrate. 2. For 1080P video, adjust bitrate to 3-6 Mbps; for 4K video, adjust to 15-25 Mbps. 3. If “VBR” is enabled, set a reasonable maximum bitrate limit (e.g., 8 Mbps max for 1080P) to avoid insufficient peak bitrate.<\/p>\n\n\n\n

A2\uff1aCheck if the resolution matches the video source or is set too low.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Encoding resolution is lower than the video source resolution (e.g., compressing 4K source to 720P), or the resolution is set incorrectly (e.g., setting 1280×720 for a 1080P source), causing loss of detail and blurriness.<\/p>\n\n\n\n

Solution: 1. In “Encoding Settings,” check the “Resolution” option; select “Auto” or a resolution matching the video source (e.g., if HDMI input is 4K, set to 3840×2160). 2. Avoid manually setting the resolution lower than the source. If bandwidth is limited and resolution must be reduced, prefer stepping down from 4K to 1080P rather than directly to 720P.<\/p>\n\n\n\n

A3\uff1aCheck if the encoding format and GOP settings are reasonable.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Using a less efficient encoding format (e.g., H.264 has lower compression efficiency than H.265, resulting in poorer quality at the same bitrate), or GOP value is too large (causing noticeable compression artifacts during scene changes).<\/p>\n\n\n\n

Solution: 1. If the device supports it, switch the encoding format to H.265 in “Encoding Settings” (clearer picture at the same bitrate). 2. Check the GOP value. Default is typically “1-2 times the frame rate” (e.g., 30-60 for 30fps video). For dynamic scenes (e.g., sports), reduce the GOP value (e.g., set to 30 for 30fps) to reduce compression blur.<\/p>\n<\/details>\n\n\n\n

Q6: When jumping from KiloLink Server Pro to the device Web page, the audio encoding bitrate can only be selected as 128Kbps, cannot adjust to other values?<\/strong><\/summary>\n

A1\uff1aConfirm if the current audio encoding channel is the “Bonding-Only Audio Channel”.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: To ensure compatibility for bonding streaming, P3\/P3-mini by default sets the bitrate for the “Bonding-Only Audio Channel” (name usually “Bonding-Only”) to a fixed 128Kbps. This channel is only for bonding streaming and its bitrate cannot be modified.<\/p>\n\n\n\n

Solution: 1. If you need to adjust the bitrate for “Local Streaming,” go to the Web backend “Audio Encoding Settings,” click “+ Add” to create a new audio channel (e.g., name it “Local-Stream”). 2. In the new channel, you can select any bitrate from 16-512 Kbps (e.g., choose 64Kbps for local streaming to save bandwidth). After setting, select this new channel in “Local Streaming.”<\/p>\n\n\n\n

A2\uff1aCheck if you accidentally operated on the bonding stream channel.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: If you only want to adjust the audio bitrate for “Bonding Streaming,” since the bonding channel bitrate is fixed, it cannot be modified directly; audio quality needs optimization through other means.<\/p>\n\n\n\n

Solution: 1. No need to modify the bonding channel bitrate (128Kbps already meets bonding compatibility). 2. If audio quality seems poor, confirm in “Audio Encoding Settings” that the sample rate is 48 KHz (clearer than 44.1 KHz), or switch the encoding format to AAC (better quality than G.711).<\/p>\n<\/details>\n\n\n\n

Q7: Browser accesses the device Web login page, but it displays incompletely, is blank, or reports “Failed to load”?<\/strong><\/summary>\n

A1\uff1aFirst, try changing the browser or using a private\/incognito window.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Poor browser compatibility (e.g., old 360 Browser, QQ Browser) or corrupted cache\/Cookies cause page rendering issues.<\/p>\n\n\n\n

Solution: 1. Switch to a mainstream browser like Chrome, Firefox, or Edge, and re-enter the device IP to access. 2. If still abnormal, open a browser “Private Window” (Chrome shortcut Ctrl+Shift+N), then enter the IP to log in, avoiding cache interference.<\/p>\n\n\n\n

A2\uff1aClear browser cache and cookies.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: The browser’s cached old page data conflicts with the current device Web version, causing display errors.<\/p>\n\n\n\n

Solution: 1. In Chrome, click the three dots \u2192 Settings \u2192 Privacy and security \u2192 Clear browsing data. 2. Select “Cookies and other site data” and “Cached images and files,” choose “Time range: All time,” clear, then restart the browser and revisit.<\/p>\n\n\n\n

A3\uff1aCheck if the network between the device and computer is connected.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Network unreachability prevents page loading, e.g., computer and device are not on the same LAN, or device IP is entered incorrectly.<\/p>\n\n\n\n

Solution: 1. Confirm the computer and device are connected to the same network (same Wi-Fi or wired LAN). 2. Press Win+R, type “cmd,” execute ping device_IP (e.g., ping 192.168.40.124). If it shows “Request timed out,” recheck the device IP or network connection.<\/p>\n<\/details>\n\n\n\n

Q8: When wired, Wi-Fi, and 4G\/5G networks are connected simultaneously, which network does local streaming use? How to specify a network for streaming?<\/strong><\/summary>\n

A1\uff1aFirst, understand the network priority rule for local streaming.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: Local streaming defaults to the priority order: “Wired network > Wi-Fi > 4G\/5G”. If a higher priority network is available, lower priority networks are automatically ignored; no manual setting is needed.<\/p>\n\n\n\n

Solution: 1. To confirm the currently used network, check the “Uplink Rate” corresponding network on the LCD screen “Bonding” interface or Web backend “Network Status” (e.g., if the wired network shows a rate, it’s the current one). 2. To force the use of a specific network (e.g., prefer Wi-Fi), disconnect the higher priority network (e.g., unplug the Ethernet cable); the device will automatically switch to the next available network.<\/p>\n\n\n\n

A2\uff1aManually specify the network interface for local streaming.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: In special scenarios (e.g., wired network bandwidth is insufficient, want to use 4G\/5G instead), manually specify the streaming network to prevent the device from auto-selecting an unsuitable link.<\/p>\n\n\n\n

Solution: 1. Enter the Web backend “Network Settings,” find the unwanted network (e.g., wired network), click “Disable”. 2. Keep only the target network enabled (e.g., 4G\/5G), then initiate local streaming; data will go through the specified network. 3. To restore auto-selection later, re-enable the previously disabled networks.<\/p>\n\n\n\n

<\/p>\n<\/details>\n\n\n\n

Q9: After connecting power, the device does not power on, power light is off, and there is no response?<\/strong><\/summary>\n

A1\uff1aCheck if the power adapter connection is secure<\/strong><\/p>\n\n\n\n

Troubleshooting Reason: The power adapter is not plugged in firmly (loose on either the device end or the socket end), causing no power to the device.<\/p>\n\n\n\n

Solution: 1. Confirm the power adapter’s DC plug is fully inserted into the device’s “Power Interface” and screwed tight if it has a locking mechanism. 2. Check if the other end of the adapter is plugged firmly into the power socket; try a different socket (e.g., switch from a power strip to a wall outlet).<\/p>\n\n\n\n

A2\uff1aConfirm the original power adapter is being used.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:Using a non-original adapter (e.g., incorrect voltage\/amperage, such as using a 12V\/2A adapter to replace the original 12V\/3A) provides insufficient power, preventing the device from starting.<\/p>\n\n\n\n

Solution:1. Check the label on the bottom of the device to confirm the original adapter specifications (P3\/P3-mini original adapter is typically 12V\/3A). 2. Replace it with the original adapter. If the adapter is lost, contact the dealer or visit the Kiloview official website to purchase an original accessory.<\/p>\n\n\n\n

A3\uff1aCheck if the power adapter is damaged.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:A broken adapter cable, damaged interface, or internal fault prevents it from supplying power.<\/p>\n\n\n\n

Solution:1. Inspect the adapter cable for obvious damage, breaks, or bending, and check the interfaces for rust or deformation. 2. Use a multimeter to measure the adapter’s output voltage (requires operation by a professional), or test with another original adapter with the same specifications. If the device powers on after replacement, it indicates the original adapter is damaged.<\/p>\n\n\n\n

<\/p>\n<\/details>\n\n\n\n

Q10: HDMI input video has a picture, but no sound (No audio levels on the Web interface, no sound when decoding with VLC), while SDI input sound is normal?<\/strong><\/summary>\n

A1\uff1acheck if the video source has HDMI audio output enabled.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:The video source (e.g., camera, computer) has not enabled HDMI audio output, only sending a video signal, so the device cannot capture sound.<\/p>\n\n\n\n

Solution:1. For a computer, go to “Sound Settings,” and change the “Default Output Device” to “HDMI” (instead of speakers). 2. For a camera, find “Audio Output” in the “Settings,” confirm “HDMI Audio” is enabled, and the volume is not set to 0.<\/p>\n\n\n\n

A2. Check if the device audio source is set to “HDMI”.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:The device audio source is mistakenly set to “SDI” or “Line In,” not switched to HDMI, causing it to fail to recognize the audio signal from HDMI.<\/p>\n\n\n\n

Solution:1. Go to the “Audio Settings” on the Web backend or LCD screen, and select “HDMI” in the “Audio Source” option. 2. Check the “Audio Level” display on the Web interface; if there are moving green bars, it indicates audio is being captured normally. If not, proceed to the next step.<\/p>\n\n\n\n

A3. Check if the HDMI cable is intact or replace the cable.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:A poor-quality, damaged, or loosely connected HDMI cable can interrupt the audio signal transmission (some older cables only support video transmission, not audio).<\/p>\n\n\n\n

Solution:1. Re-seat the HDMI cable, ensuring both ends are plugged in firmly. 2. Replace it with a new HDMI cable version 1.4b or above (the device supports HDMI 1.4b), preferably choosing a cable with a shield to avoid interference. 3. If you have a spare HDMI cable, replace it directly for testing to rule out cable issues.<\/p>\n\n\n\n

A4. Check if the device EDID settings are compatible with the video source.<\/strong><\/p>\n\n\n\n

Troubleshooting Reason:Inconsistency between the device’s EDID (Extended Display Identification Data) and the video source during negotiation causes the audio format to be unrecognized (e.g., the video source outputs 44.1KHz audio, but the device’s old firmware only supports 48KHz).<\/p>\n\n\n\n

Solution:1. Go to “Settings -> EDID Settings” in the Web backend, click “Export” to view the current EDID, and confirm if it supports the video source’s audio format (new firmware supports 16\/32\/44.1\/48KHz; old firmware only supports 44.1\/48KHz). 2. If the firmware version is too old, upgrade the device to the latest firmware via “System Settings -> Firmware Upgrade”. 3. If the issue persists, click “Reset” in the EDID settings to restore the default EDID, then reconnect the video source.<\/p>\n<\/details>\n\n\n\n
