    HDMI® + Ethernet and IR Extender Using Cat5e or CAT6 Cable - Extend Upto 328ft

    This all-in-one HDMI® extender not only handles high-speed 1080p HDMI video, with high-resolution audio, but it also transmits the IR signal and your ethernet over a single Cat5e/Cat6 cable at distances up to 100 meters (328 feet)!

    This HDMI extender is able to send High-Speed (1080p) HDMI signals to distances up to 100 meters (328 feet), with full 10.2 Gbps bandwidth, using only a single Cat5e/Cat6 cable. It supports 3D video modes and high-resolution audio, such as DTS Digital, Dolby Digital, DTS-HD Master Audio™, and Dolby TrueHD™.

    It also includes and IR back-channel, so you can control your equipment from the destination room. The IR receiver and transmitter are large, wide-directional units, so the receiver can handle inputs from various angles and the transmitter can send the IR signal to several pieces of equipment.

    The HDMI Sender and Receiver units each feature a three-port Ethernet hub. Connect a cable from your wired router to one of the hub ports and the other five can be used to connect PCs and other internet capable devices. The ethernet signal can be transmitted at a full 100 Mbps alongside the HDMI and IR signals.

    The Sender and Receiver units can be fixed to a flat surface (wall, table, inside a cabinet, etc) using the included L brackets (4 each) and screws (8 each, 2 per bracket). Screws or bolts needed to fix the brackets to your surface are not included. Both the Sender and Receiver require 5 VDC power and a pair of AC Adapters are included.

    There simply is no better way to extend your high-speed 3D HDMI signal over long distances. With the inclusion of IR and ethernet support, this unit give you a flexibility and capabilities that have been previously unavailable!

    Doesn't work with all cables regardless of cat5, cat5e, cat6 or cat6a

    • K. Lee,
    •  Silver Spring, MD 
    • 8/2/2016 7:46:47 AM

    Pros: -Great size, came with L-brackets, screws for mounting
    -Also came with 2 IR sensors and the DC Adapters are slim profile where the tail connector comes out from the side, thus doesn't block up an outlet on a single-gang receptacle, or power strip/linear surge protector.
    -Simple plug and play
    -Neat feature to have 3 other ethernet ports to help eliminate the need to run multiple cat 5 cables

    Cons: -expensive implementation for sending HDMI
    -does not work with all certified cat5, cat5e, cat6, and cat6a, including shielded connectors. All cables were tested and used in transmitting from network switch to network switch as well as computer terminal to network switch/internet and all came out with good throughput internet speed results. The send and/or receive unit did not work when cables were longer than 150'
    -ugly as crap IR sensors, just hide them, forever.
    -LED status indicators are as good as prehistoric paintings. We see that you are on, but blinking doesn't doesn't tell me anything more (and the manual doesn't say anything about the types of blinking). We know you are working when we see the output on our display.. we don't need an LED indicator telling us something that we already know.

    I was really excited to get this unit as a substitute for a well known brand HDMI extender that I'm currently using for professional installs. I did various tests and trials and come to find out that the weakest link to the unit itself is HDBaseT connections (although I did not do a full-on throughput test to see what and where the lag will be or why the send and receive units would just sit and wait for a signal). Sadly enough, I couldn't recommend this product for a professional setting since it seems to be unreliable with longer runs than 150'. I had various lengths from 10' to 200' Cat 5, 5e, 6, and 6a at 24 awg and 26 awg. As appropriate, I wanted to make sure this unit can work with a 6a SFTP with shielded connectors because the cables could be installed in an environment full of noise and interference for such long run within a building. For shorter lengths running under a 100' using other cat5/5e and a cheaply made UTP cat6, the signal would go through and I would get my images to display with about an expected 1 to 2 seconds of handshaking/connection. I sent a full 1920x1080 resolution from various laptops coupled using anywhere from 1' to 15' HDMI cables and it would work with a shorter (under 100') run cat5/5e/6 cable, but not a 6a at 24 awg. Go figure, granted that this product clearly states "use cat5e or cat6. The unit isn't defective, just not all that great to push the signal all the way through from HDMI source to HDMI source. While it is nice to have the extra ethernet ports on them, this is just an overpriced 3-port switch to me if the HDBase-T doesn't work well with the HDMI at longer runs. Still expensive for what it is now that you can get new slim run HDMI fiber cables (14316) if HDMI was your primary use.

    I'll reserve my rating to a 3 for now until Monoprice can get back to me of their recommended cables that can extend to the 100 meters that they are claiming for this unit. Typically, it's much easier to replace these units which are at the ends and not the cable when it comes to installation. Who would want to mess with fishing and pulling cable because the units aren't compatible (especially when the ethernet cable is robust and it's doing its job)?

    Love these things

    Pros: Does exactly what it is supposed to do. Simple easy to interpret status lights. Lightweight and fairly compact.

    Cons: Have on rare occasions needed to unexpectedly cycle the power to get these to work after periods without use.

    I have three of these now, one of which I have had for at least a year and they are working flawlessly. I am using these throughout my house as I have all my a/v equipment centrally located in my basement. These are transmitting all forms of audio and video without a glitch. I believe I have experienced excessive latency when using the Ethernet and HDMI extender although I don't have data to support this. I strictly use these for the HDMI extension function. I have zero experience with the IR senders and receivers.

    replacement parts?

    • Mike,

    Pros: Overall very good. Fast setup and very little problems out of the box. These work well on CAT5e UTP. Great functionality overall. 3 LAN ports per end is very helpful....

    Cons: One way IR. Failure rate. When failure is within warranty period Monoprice is receptive and does a good job with replacements - although they used to offer AWR and have now resorted to requiring defective units shipped in and bench tested before sending replacements. This is a problem for customers - causing extended down times.

    We have used many of these for our customers. We have experienced about a 10% failure rate at this point. In most cases it appears the receiver end is the failure unit. It would be very nice to offer the receiver and transmitter individually. The warranty is one year and we are seeing about half failures beyond the warranty period. I would much rather pay for only the unit needed to get pair back up and running vice buy a whole new set.

    PID 8123 and PID 8122

    • Jaspal,
    •  Edmonton, AB 
    • 1/12/2015 9:18:25 PM

    Pros: The products worked fine

    Cons: The products did not last long

    I paid lots of money to buy these products, however, I'm disappointed to see them fail. These products needs to last a bit longer.

    Hello Jaspal,

    Thank you for your review and truly sorry to hear about the issues experienced with PID 8123. If I may ask, what problems are you running into exactly when trying to use this extender? Are the units powering on at all? Also, what is the order number for this purchase? Please let me know so we can look into this further. Thank you in advance!

    Thanks for your reply. All boxes (receiver/sender) have a power light on, however, the link and data light is not coming on. Hence, products failed to work. I don't have any invoices for these products.


    by Monoprice Administrator
    Hi Jaspal,

    Thank you for the response! Please provide me with a bit more information just so we can investigate this further. How long did the extender work before giving out and were there any changes made to the setup prior to them failing? What are the lengths and gauges (AWG) of the HDMI cables in use here? What about length and type of Cat cable? Also, what devices are you trying to connect with this extender? Have you tried other devices to see if the issue persists?

    If I may ask, what was the email address used to purchase the units? I can try finding the order that way. Thank you!

    Not reliable enough for corporate use

    • Anonymous,
    •  El Segundo, CA 
    • 11/18/2014 1:27:26 PM

    Pros: Good value while it's working. I typically used it up to 200' with Cat6a with no connection problems.

    Cons: Receiver died out of warranty with very little use

    I have 3 HDbaseT extenders from Monoprice and 2 of them have died at the same time. They sit on a shelf until needed for corporate jobs. On this one the receiver no longer has link or HDCP leds lit. Tried cables, sources, monitors, power supplies and it's dead. Out of warranty of course. Fortunately they're inexpensive enough to buy two sets to have a backup.
