Profile:
What an excellent and
compact FM unit. BEWARE that most 900MHz sets you'll find are AM
and usually junk. We've carried this unit for years and it has proven
to be stable and reliable when properly used and powered. Even inferior
units can be found out there costing twice as much or even more!
We have tested this unit at over 1 mile in LOS (line-of-sight) conditions
with our TX/THX-9500 transmitters using ONLY the standard omnidirectional
whip antennas at both transmitter & receiver points. It is capable
of greater reception range when transmitter and/ or receiver are
equipped with properly oriented directional (narrow beam) antennas.
This can be a GREAT solution
for a WIDE variety of uses- both mobile and stationary. It's often
the best alternative for situations which may not be as suitable
for microwave frequencies (i.e. 2.4GHz or 5.8GHz). Microwave transmitter
or receiver are in motion or used around people or animals. 900MHz
is also better at barrier penetration than higher frequencies.
900 megahertz is also
a great alternative to using 2.4GHz in conditions where other 2.4GHz
equipment is (or even could be) operating in close relative proximity
to either transmitter or receiver- or anywhere in between. This
type of interference may include wireless LAN networking, 2.4 gig
cordless telephones, alternate video transmission, microwave ovens
and other sources.
For security purposes,
900MHz is also less likely to be received by accident or intercepted
by unwanted 'video eavesdroppers'.
It must be noted that,
even though a quality FM 900MHz unit has a number of potential advantages
over other wireless video frequencies, any wireless video- even
if incredible- is certainly not 'magic'. There should always be
a careful analysis of all known factors and a preparedness for certain
types of potential problems which can never be fully realized until
trial. Please read more on our wireless FAQ page.
We carry ONLY wireless
equipment manufactured with quality-engineered onboard surface mount
board + processor components (critical to produce a high quality
wireless video unit). Too many in our industry are making false
and exaggerated claims about their inferior products and about wireless
video technology in general. You never have or will find such products
or erroneous information on our site.
Common Applications:
•General CCTV video
and security purposes where installing hardwired connection is not
feasible or possible
•Mobile and bodyworn portable videography including use at
wedding receptions, in nightclubs, etc.
•Unmanned aerial vehicle (UAV) and R/C (radio controlled)
vehicle applications including robotics
Available Options:
External receiver antenna
included FREE (SMA type threaded post) for direct interface to unit.
Fully regulated #PWR-500R
AC/DC transformer (wall plug-in for constant use) included FREE
with each #RX-910 ordered.
The #RX-910 features
identical power requirements to most of our transmitters and cameras
and can therefore also be powered by our #BAT-1/3/AAA battery packs
or our #ACC-AUTO fused auto power cord for direct plug into vehicle
cigarette lighter.
Our #ANT-900M magnetic
mount + low-loss extension cable (with SMA plug) allows user to
stretch antenna distance away from a transmitter or receiver, such
as outside a building or to the rooftop of a vehicle. Elevated #ANT-900M
antenna(s) can facilitate a much better LOS line of sight condition
between transmitter and receiver in crowded rooms, etc., which often
results in better range and performance.
Our #ANT-Y900 high gain
Yagi antenna allows user to MAXIMIZE range in LOS conditions by
concentrating radio signal into a narrow, directional beam. *Please
note that #ANT-Y900 is very large at almost 5 feet. #ANT-Y900 antenna
features "N" type post jack. TO interface directly with
transmitter or receiver, you must use the proper "N-SMA"
type cable, which we carry and can be found on the antennas page.
Cautions:
This is a non-weatherproof
receiver, and as such- must be treated with extra care and NEVER
left outdoors without the proper protective housings.
This unit features a
built-in auto sequential function which, when initially powered,
begins to automatically switch between available channels for a
few seconds each. Several of our customers have been confused by
this, and have reported intermittent transmitter failure when only
actual problem was failure to select the proper channel. User must
simply depress the button of desired channel (same as transmitter
is set to) and this receiver will maintain a 'lock' on that channel
only until unit is powered off again.
Because this unit has
no built-in 'reverse polarity protection' circuitry, it MUST be
powered PROPERLY and ONLY with available CD3 Video Security power
accessories to guarantee SAFE operation. Using improper 'reverse
power' (i.e. a power supply with a. Unregulated transformers marked
at "12 volts DC" are more likely producing 18-30 volts,
as seen when tested with a simple DC volt meter. While over-voltage
of electronic circuitry may allow operation, but may also be greatly
decreasing device longevity by "over-driving" and likely
overheating that circuitry, which may even result in immediate damage.
Please consult our power FAQ page for more information.
Reception range of wireless
performance is based on a number of factors which can generally
be determined only after actual testing has been made. Please consult
our wireless FAQ page for MUCH more information on this subject.
This type of wireless
equipment is typically more suited for CCTV camera and security
applications, rather than with consumer entertainment-type devices.
