Get 4K at 60Hz from 70 m (230 ft.) away
This HDMI over CAT6 extender maintains your Ultra HD 4K picture quality, even at 70 m (230 ft.) away from your video source. If you're not running 4K video, this extender supports High-Definition 1080p 60Hz and lower resolutions at even greater distances, up to 100 m (328 ft.) from your HDMI source.
With full support for your HDMI 2.0 equipment, including 4K resolution at 60Hz, this extender can transmit at a bandwidth of up to 18Gbps, making it the ideal solution for high-resolution tasks requiring the highest color detail. For smoother video and color transitions, the extender offers 4:4:4 chroma subsampling via visually lossless compression, meaning every pixel gets its own unique color.

Simplify your setup
The HDMI Extender Over CAT6 offers a hassle-free solution for your digital signage project. The extender only requires a single CAT5e or CAT6 cable, so you extend an HDMI signal using existing infrastructure that’s already in your building.
Plus, this HDMI extender supports Power Over Cable (POC), which means you’ll only need one power adapter connected to either your transmitter or receiver. Mounting hardware is also included for discreet, professional installation.

the bank account listed below. Alternatively, you may visit your local branch,
fill out a Deposit Slip with the correct details using the information below
and process this transfer with the bank teller in person.

Please add your invoice number and name in the description area when placing your deposit. If you do not have the relevant details on hand, or are unable to add the description, please email or fax through a copy of your deposit receipt as soon as possible. Please note that your order will not be processed until the funds have successfully deposited into our bank account and the payment has been confirmed as received by our accounts department. This process takes 1 - 5 business days.
Credit Card
Zotim accepts all major credit cards - Visa,
Master Card and Debit Cards. Please note, credit card handling fees do apply as
follows: VISA/MasterCard at 1.5%. These fees are comprised of Merchant Service
fees, Terminals fees, fraud prevention costs that cannot absorb due to the
extremely lower than retail prices we offer.
Please note: Due to the rise of credit card fraud
and for your security all credit card orders will be subject to advanced
security checks. If your order does not meet our security check requirements,
you will be contacted and further credit card security procedures will be
implemented.
Shipping
We prefer to use couriers for shipping which include Couriers Please. Startrack and Toll Express.
The courier require a signature on delivery so please give a delivery address where someone will be available to sign for the parcel.
We can use Australia Post as well, however parcels sent through Australia Post are not insured for loss or damage.
How is shipping cost calculated?Shopping at zotim.com.au is all about how much you can save with our shipping methods. As a brief summary - if you buy more than 1 item, your shipping cost for the 2nd, 3rd & subsequent items will be less than the first item!
We can afford this mainly because the cost of the delivery driver travelling to your address is already covered by the first parcel delivery charge, so the remaining parcels are only charged by the additional weight.
Note that we aren't always able to add items to orders after the order is placed, so be sure to order everything you want in one go when you first checkout, to ensure the quickest possible processing of your order, and the lowest possible shipping cost. We also aren't able to merge orders - the above images show what is possible if all items from Order 1 and 2 are ordered on a single order, it does not infer that we can combine multiple orders (our system is unable to accommodate this at this time).
