XK-J213T Backpack COFDM Video Transmitter
Carry video transmission and two-way voice in a backpack-format system. XK-J213T combines HDMI, SDI and CVBS input choices with H.265 video encoding for mobile field equipment paired with a suitable receiving station.
- Backpack format supports a carried video system rather than an installation inside a small camera platform.
- HDMI, SDI and CVBS input choices accommodate different field video sources.
- A built-in voice receive/transmit module is intended to work with a matching two-way voice receiver at the receiving station.
- 240 × 125 × 46 mm and ≤1.5 kg excluding battery define the listed transmitter size and weight.
XK-J213T Backpack COFDM Video Transmitter Overview
XK-J213T is a backpack-format COFDM video transmitter for a mobile operator who also needs a voice connection to a receiving station. It lists H.265 encoding and HDMI, SDI and CVBS video inputs, allowing the source interface to be selected around the field camera.
The product description separates the video link and a built-in two-way voice module. Xingkai checks the receiving-station arrangement, camera and power provision, then specifies the transmitter and agreed accessories in a quotation. The battery and complete carried assembly should be identified separately from the transmitter’s listed weight.

Connections and Integration
HDMI, SDI or CVBS connects the selected video source. The product lists a built-in voice receive/transmit module for use with a matching two-way voice receiving station; the voice receiver frequency is 840–845 MHz, separate from the listed 300–800 MHz customizable video transmission range. RS232 configuration and data ports are also listed. Xingkai checks the video and voice equipment together when specifying the system.
Product view and enlarged detail are from one photograph. Supplied configuration is confirmed in the quotation.
Specify the J213T Video and Voice Equipment
Define the mobile video path and two-way voice arrangement together. The J213T quotation identifies the backpack transmitter, H.265 receiving equipment and the matching voice-station scope, with headset, battery and cable requirements stated separately for the agreed supply.
Send the camera output and video format, required video channel and receiving-station details. Identify the two-way voice equipment and headset to be used, battery voltage range, carried-load allowance and quantities.
Xingkai checks the 300–800 MHz video configuration and H.265 receiving arrangement, then checks the proposed voice-station version and interfaces against the J213T configuration, including its own listed 840–845 MHz voice-receiver entry. The quotation identifies the specified transmitter, receiving equipment and agreed accessories.
Agree the video and voice components, headset interface and supplied cable scope. Confirm the battery arrangement against 8–25 V DC input and account for battery weight separately from the ≤1.5 kg transmitter before agreeing delivery terms.
Xingkai supplies and ships the agreed J213T video/voice equipment and listed accessories according to the confirmed order.
FAQs
Send the battery voltage over its operating range, output connector, protection or regulation arrangement and the other equipment sharing the supply. Xingkai checks the proposed power arrangement against the selected transmitter configuration; battery inclusion and connectors should be explicit in the quotation.
Describe the video recorder’s required input and recording format independently of the voice equipment. J213T sends an H.265 video feed and lists 840–845 MHz for its own voice receiver. Identify the matching voice station’s model, version and interfaces separately so its pairing can be checked. The quotation should distinguish the video receiving/recording equipment from the voice station and headset arrangement; two-way voice does not itself establish a recorder.
The presence of a two-way voice module does not establish headset connector, wiring or electrical compatibility. Send the headset model and interface details with the receiving-station requirements so Xingkai can check the proposed voice accessories.
The described J213T configuration includes video formats up to 1080p60. State the exact resolution and frame rate, the HDMI, SDI or CVBS camera output, and the format needed for receiving display or recording. If the project requires 4K, request confirmation of a separately identified supply configuration before choosing the receiving equipment; H.265 encoding alone does not establish that resolution.
Runtime depends on the selected battery, operating settings and complete connected load. Provide the required operating duration and proposed battery arrangement. Request the electrical requirements for the quoted configuration before choosing a battery; no runtime is specified for an unidentified battery here.
