HDMI Extenders for CCTV, Home & Small Business Use
9 products in our Accessories range — trade-grade UK stock from CCTV Master.
HDMI extenders let you send a video (and usually audio) signal from a DVR, NVR, or monitor source further than a standard HDMI cable can reliably manage. For CCTV setups, that typically means running a display from a recorder in a cupboard or rack through to a monitor or TV in another room.
This range covers 8 HDMI extender products, giving you options depending on how far you need to run a signal and what cabling route is practical in your property.
How to choose
- Distance needed — check the rated maximum run for each unit; picking the wrong one for your distance is the most common cause of a poor picture.
- Cabling method — some extenders work over Cat5e/Cat6 network cable rather than HDMI, which is often easier to route through walls and lofts.
- Power supply — confirm whether the transmitter, receiver, or both need mains power at each end.
- Resolution support — match the extender's supported resolution to your DVR/NVR or monitor output so nothing gets downscaled.
Always check the extender's specification against your recorder or monitor's HDMI output before buying, especially if you're running a long cable route or need to support a high resolution.
HDMI-EXTENDER — frequently asked questions
Why would a CCTV installation need an HDMI extender?
If your DVR or NVR is located far from the monitor or TV you're viewing footage on, a standard HDMI cable may not reach or hold a stable signal, so an extender bridges that gap.
Do HDMI extenders always use HDMI cable for the long run?
Not always — some extenders in this range send the signal over Cat5e/Cat6 network cable instead, which can be easier to route than bulky HDMI cable.
Do I need a power supply at both ends?
This depends on the specific extender, so check the transmitter and receiver power requirements for the exact model before installing.
