Dahua DH-PFM702 4K 30Hz Black HDMI Extender with PoC IR & CAT6 Transmission 40m 4K 50m 1080p

Product SKU: DH-PFM702

Product Overview

The Dahua DH-PFM702 HDMI Extender is a transmitter and receiver set designed to carry high-definition HDMI signals over a single CAT6 shielded network cable when a conventional HDMI cable run is too long for reliable transmission. It supports up to 4K/2K@30 Hz YUV 4:4:4 over distances of up to 40 m, while 1080p@60 Hz can be transmitted up to 50 m. The system also provides one-way PoC from the transmitter to the receiver, one-way IR signal transmission, EDID copying and an HDMI loop-out function for more flexible display layouts. Supplied with the transmitter, receiver, IR cables and locking power adapter, the DH-PFM702 is suited to monitoring displays, conference environments, teaching spaces and large-screen installations where the HDMI source and display need to be positioned farther apart.

System Capabilities

Best For

• CCTV Monitoring Displays: Extend an HDMI output from source equipment to a monitoring screen positioned farther away without relying on an unusually long HDMI cable.
• Conference Rooms: Useful where presentation or source equipment is located away from the main display and a CAT6 cable route is more practical.
• Teaching Environments: Supports longer HDMI connections to classroom or training-room displays where the equipment and screen are installed in separate positions.
• Large-Screen Displays: Suitable for installations requiring 4K/2K@30 Hz transmission up to 40 m or 1080p@60 Hz transmission up to 50 m.

Why Choose This Kit

The DH-PFM702 is useful when an HDMI source and display are too far apart for a straightforward HDMI cable installation but still sit within a practical CAT6 cable route. Compared with a simple signal extender, this set combines 4K/2K@30 Hz transmission, one-way PoC, one-way IR extension, EDID copying and HDMI loop-out capability in the same compact system. The 40 m limit for 4K and 50 m limit for 1080p also gives buyers clearly defined installation boundaries before cabling begins. Available through Security Wholesalers, the DH-PFM702 is particularly well suited to surveillance displays and commercial AV installations where minimising additional cabling around the remote display can simplify the finished installation.

Recommended Use

Choosing the Right Kit

• Choose the DH-PFM702 if: You need to transmit HDMI over CAT6 shielded cable for up to 40 m at 4K/2K@30 Hz or up to 50 m at 1080p@60 Hz and would benefit from one-way PoC, IR transmission or HDMI loop-out functionality.
• Choose a different HDMI extension solution if: Your installation requires 4K transmission above 30 Hz, a cable distance beyond the confirmed limits, or a transmission medium other than the specified CAT6 shielded network cable.

FAQs

1. What does the Dahua DH-PFM702 HDMI Extender do?
   The Dahua DH-PFM702 extends HDMI signals over a single CAT6 shielded network cable when a conventional HDMI cable run would be too long or unreliable. The transmitter and receiver work together as a one-channel extension system, supporting up to 4K/2K@30 Hz and 1080p. It is intended for applications such as monitoring displays, conference rooms, teaching environments and other large-screen installations where the source and display need to be separated by a longer cable distance.
2. How far can the DH-PFM702 transmit 4K and 1080p video?
   The DH-PFM702 supports a maximum transmission distance of 40 m for 4K/2K@30 Hz and 50 m for 1080p@60 Hz when using a single CAT6 shielded network cable. These are the confirmed distance limits in the supplied datasheet, so buyers should plan the cable route around the required resolution rather than assuming the same maximum distance applies to both 4K and 1080p operation.
3. Does the DH-PFM702 support 4K video?
   Yes. The DH-PFM702 supports video resolution up to 4K/2K@30 Hz with YUV 4:4:4, as specified in HDMI 1.4. It is also HDCP 1.4 and DVI 1.0 compliant. For a 4K installation, the confirmed maximum CAT6 transmission distance is 40 m, so this model is better suited to 30 Hz 4K display applications than to installations that specifically require higher-refresh-rate 4K transmission.
4. What is PoC on the Dahua DH-PFM702?
   The DH-PFM702 supports one-way PoC from the transmitter to the receiver. This means the receiver can receive power through the same CAT6 link from the transmitter side, reducing the need for a separate power connection at the receiver location. The system is supplied with a 12 VDC, 1 A locking power adapter for the transmitter side, and the confirmed power consumption is 1.86 W for the transmitter and 0.87 W for the receiver.
5. Can the DH-PFM702 carry infrared remote-control signals?
   Yes. The DH-PFM702 supports one-way IR signal transmission. The transmitter provides one IR OUT port and the receiver provides one IR IN port, and the package includes a 1.5 m IR blaster cable plus a 1.5 m IR receiver cable. This is useful when the HDMI source equipment is located away from the display and basic infrared control needs to be extended across the same installation.
6. What cable should be used with the DH-PFM702?
   The DH-PFM702 is specified for CAT6 shielded network cable. The transmitter and receiver each provide one RJ-45 network port, and the confirmed maximum distances are 50 m for 1080p@60 Hz and 40 m for 4K/2K@30 Hz. Buyers should use the specified shielded CAT6 transmission media when planning the installation rather than treating the extender as suitable for any network cable type.
7. Does the DH-PFM702 provide an HDMI loop-out connection?
   Yes. The transmitter has two HDMI ports and the receiver has one HDMI port, and Dahua states that the unit allows cascading through an additional HDMI loop-out port. It also supports copying EDID from either the receiver display or the loop-out display. This is useful where a local display is required near the source while the same HDMI signal is also being extended to a more distant display.
8. What is included with the Dahua DH-PFM702?
   The DH-PFM702 package includes one transmitter, one receiver, one 1.5 m IR blaster cable, one 1.5 m IR receiver cable, one 12 VDC/1 A locking power adapter, one user manual, and one legal and regulation information document. When purchasing through Security Wholesalers, check that your planned display resolution and CAT6 cable distance fit the confirmed 40 m 4K or 50 m 1080p limits before installation.
