The Stamp Miniature Video Sender Transmitter |
|
| |
|
|
|
| |
|
Our Video Sender units
are designed to transmit high quality pictures and sound from a
camera to a monitor using legal, licence free 2.4 MHz microwave
link. The Stamp is an incredibly small and
lightweight Video Sender Miniature Transmitter - literally the size
of a postage stamp and weighting only eight grams! Ideal for
situations where the monitor will be close to the camera, but you
need to work without a cable.
The Stamp is so small and light it is practical to
use it even with DV Cams. |

Standard 5 Channel Video Sender Receiver - Mk
2 |
|
| |
|
|
|
| |
|
The new Mk 2 Receiver -
much smaller (about 45%) than the Mk 1 unit! - is designed
to receive microwave signals from the Transmitter and display high
quality pictures and sound on any monitor of your choice, as before. It
is compact and light in its new, robust die-cast case, and the
efficient omni-directional aerial
a right angled SMA connector comes as standard.
You
can expect up to 300 metres range outdoors (line of sight) or up to
30 metres indoors. However, in this case, with The Stamp the
ranges you can expect are 50 or 15 metres respectively.
The Receiver can be powered from any nominal 12 volt source capable
of supplying 130mA. The actual voltage range is from 8 to 16
volts and is applied via the 4 pin Hirose socket on the end of the
unit. |

INSTRUCTIONS FOR USE |
| |
|
|
|
| |
|
|
The Stamp Miniature Video Sender Transmitter |
|
| |
|
|
|
| |
|
Plug the
right-angled BNC into the camera's video out socket and the Hirose
into the camera's power socket.
The Stamp will not blow the
fuse on early DigiBetas - current consumption is only 70mA.
Velcro The Stamp to the camera -
and that's it!
If you don't have a Hirose
socket on your camera, The Stamp can be powered from a PP3 type 9
volt battery by using our
PP3 Clip Adapter,
or our
PP3 Battery Box. We can
also make adapter leads to almost any plug and power source if
needed.
The Stamp will run on any voltage
from 6 - 15 volts, it has an internal voltage regulator.
Experiment to find the best place
for The Stamp. Usually the highest point on the camera is
best, on top or on the back of the battery often works well.
We can supply The Stamp to
transmit on any of the 5 channels our standard Video Sender Receiver
works on, or custom frequencies to order. The coloured dot on
the top of the unit indicates the channel. Please check our
Frequency Chart
(or the
TX/RX Specifications Comparison)
for more information.

Standard 5 Channel Video Sender Receiver - Mk
2 |
|
| |
|
|
|
| |
|
Video is output via the BNC socket and sound via the
3.5mm stereo jack socket.
Use the rotary selector switch to ensure the
Receiver is set to the same channel as the Transmitter.
Switch on the unit using the toggle power switch
on the end of the unit and check the red light comes on.
We can supply suitable batteries, mains power pack and cables if
required.
Make sure the aerial is vertical and clear of any
surrounding metalwork or obstructions.

PROBLEM SOLVING |
| |
|
|
|
| |
|
|
If you experience
interference or bad picture break-up try another channel, as it
is likely there is another unit on the same frequency.
Don't forget that the Receiver must be on the same
channel as the Transmitter! By default, The Stamp is supplied
on channel 1, unless you have specified a different channel. As mentioned already mentioned above, please
check our
Frequency Chart
(or the
TX/RX Specifications Comparison)
for more information. |
|
| |
|
| |
|
|
Note that only channels 1 to
5 on the channel selector on the Receiver are valid. |
|
| |
|
| |
|
|
The Stamp
has an omni-directional aerial which radiates in all directions.
It is very important that the aerial tip is free of space with no
objects or wires near it. |
|
| |
|
| |
|
|
When using the Sender indoors reflections from
girders, wiring, etc, will cause occasional flashes on the received
picture when cancellation occurs. This will only happen when
the Transmitter or Receiver is moving relative to each other or when
objects are moved between the Transmitter or Receiver. |
|
| |
|
| |
|
|
When using The Stamp outside,
line of sight, these problems largely don't arise and the signal is
much more stable. The maximum range outdoors is about 50
metres. Indoors a range of around 15 metres should
generally be expected. |
