Baluns contain small signal transformers that are specially tuned to match the cables impedance and convert the unbalanced signal to a balanced one. PASSIVE baluns just have the transformers and very little else in them.
On some PASSIVE baluns that carry video and data signals, the data "terminals" do not go through a transformer or any other electronics and are a direct electrical connection to the CAT5 cable. These "terminals" can be useful for lots of purposes including sending low voltage (5 or 12V) from one balun to another.
Baluns are a great way to get longer video and data runs on CAT5, these items work with HD signals right up to 4K.
Designed for use with a CVBS (analogue) signal from an older CCTV camera or the analogue output of a newer 4-in-1 HD camera.
Wide range of CAT5 cables perfect for use in networking and CCTV installations. Includes LSZH, external and twin style in black and white.
These superb little Baluns are pocket rockets when it comes to sending HD video signals up to 4K down either CAT5 or 6 cable!
Pair of in-line 1ch passive baluns can transmit video up to 100m over CAT5. Baluns can be snapped together forming 1 block.
1ch Passive video balun with built in ground loop isolator, solves 2 problems at once.
This active balun range is ideal for transmitting analogue CCTV footage up to 2Km over CAT5!
