what's up it's Daniel coming to you live
from the Drone fly workshop and today we
have a special guest in the house we
have Grant hka from DJI here to talk all
about the new zenmuse h20n you don't
want to miss
[Music]
this so before we get too far ahead in
all the technical terms and everything
else tell me what the h20n is all about
quite simply nighttime operations a lot
of our you users on the public safety
space end up operating at night the
sensors that are built into the payload
here are optimized for nighttime
operation can certainly still be used
during the day as well I think we'll get
into them shortly here all right well
walk me through like all of the tech
that's in this thing cuz it's so funny
this thing looks so simple but like I
know it does so many things so tell us
all about it yeah absolutely so pull it
back here we actually have five sensors
here on the one payload so a new new
record on the the DJI side maybe six
next time but uh up top here we have a
thermal camera and same in the bottom
right the difference here though is in
the top left you're getting a bit of a
wider view so on your controller when
you're at two time zoom that's going to
be here for the wider thermal camera in
the bottom right here we have our tele
thermal camera so as you're zooming in
from two times to eight times you'll
actually notice it gets a little bit
worse at four times cuz it's going
digital zoom up here but then it'll
switch over to the second thermal camera
and at 8 times it's really magical that
you're zoomed in that far and you still
have that 640x 512 resolution that they
both bring we have a Starlight Zoom
sensor and a Starlight wide sensor
optimized for nighttime operations and
then the Laser Rangefinder here in the
top right with about a/ quar mile range
you can use for a variety of tasks
including getting a location marking
pins and helping the camera Focus okay
so the n and h20n stands for night VIs
Vision how strong are these Sensors how
good are they in low light just
mentioned there are Starlight Night
sensors so this a technology that's
built to really optimize performance in
low light scenarios so your human eye
you're kind of limited when we get to
about 20 Lux out you're really going to
have struggle to see uh other objects
color Etc on the camera side with a half
moon which would be 0.12 lucks you can
see about 500 MERS away detecting people
talking about search and rescue type
scenarios it can be very useful and the
technology behind those Starlight
sensors is actually few things one being
the pixel size it's a much larger pixel
so when you look at the specs here
you'll see that the zoom camera is 4
megapixels wide camer is 2 megapixels
and at first that might be a little
offputting but when you really get into
it a bit more that actually enables
better operations at night so zoom
camera you can still go up to 128 times
Max zoom and then the wide camera as
well still is able to give you that
wider view Starlight sensor as well you
know when you're looking at a typical
camera it's all about how much light
we're getting into the sensor so on top
of the DJI software that helps these
sensors out you also have a bit longer
shutter speed letting light in as well
so really doing everything it can on the
payload side to help out fornite
operations okay so briefly tell me about
the H20 series of payloads and their
differences so on the DJI side we have
three different options here you could
say the previous H20 series that had
been released we had the H20 which does
not include any thermal cameras so Zoom
wide and a Laser Rangefinder the h20t
adds the thermal camera on this previous
H20 series you're looking at a 20
megapixel zoom camera which is really
optimized on the inspection side where
you're going to be able to take higher
resolution photos and also have a more
precise prise thermal camera so really
optimized for both inspections and
daylight operations the h20n here still
a good option during the day as well but
it really shines at night when you're
using these different sensors and the
multiple thermal cameras for a variety
of
operations in your opinion what's the
coolest thing about this it really it's
comes down to the two thermal sensors
for me it was actually doing some real
operations uh the other day helping out
some folks and it's really a big
difference when you zoom in going from
an h20t starts to get a little grainier
when you go to digital Zoom it's just a
reality of a sensor but with this here
jumping over to that second thermal
sensor and really having that 640x 52
Clarity really helps so when you're
flying in a search and rescue type
Mission you're looking for something and
takes time and need to send the ground
team in to check it out being able to
Simply zoom in with a second thermal
camera on the drone saves you time and
saves the ground team because you can
get a better idea of what you're
actually looking at and if it's
something the ground team should really
investigate you could say well you
should fly lower too but once again
that's taking a time or B with maybe
trees obstructions you're not going to
have the ability to do so so really a
big time saer in regards to nighttime
operations and helps folks get a more
successful outcome okay so who is this
payload built for Public Safety is
really the industry that sticks out to
me you're not looking for necessarily A
precise temperature measurement with the
thermal cameras and you're often
operating at night so fire search and
rescue law enforcement this payload can
be very useful for a variety operations
there okay so are there any downsides to
the h20n versus the h20t the performance
is going to be a little worse during the
day in regards to zoom 128 times versus
200 so there's a very small amount
you're giving up there for the benefits
at night but if you're doing a critical
infrastructure inspection obviously
having the 20 megapixel camera of the
h20t series can be a benefit compared to
the Starlight sensor here that isn't
necessarily optimized for daylight
inspections does this have the typical
features of a DJI thermal camera so
you're going to have the typical
software tools like your temperature
area box spot temperature measurements
you can adjust the isotherms color Petes
all that good stuff so basically you
have your Baseline features in regards
to thermal cameras on the software side
is there anything I haven't asked you
about the new zenmuse h20n yeah I think
maybe some of the software features on
the payload very similar to the
preceding H20 Series where you can drop
pins with the Laser Rangefinder you can
do smart track people's car or custom
objects but a new software feature as
well specific to the h20n is
simultaneous Zoom so you can pair the
visual and thermal cameras together so
as you're zooming in with one the other
camera Zooms in simultaneously you have
your screen split in half there so
pretty useful to zoom both cameras at
the same time and not have to worry
about clicking one or the other you
still have the option to use them
differently but the pair option is a
nice software Edition well that's all we
have on today's episode I want to give a
big thanks to Grant from DJI for telling
us all about the zenmuse h 20 in well if
you have any questions about this
payload give us a call email us or visit
our website at dronefly outcom my name
is Daniel and I'll see you next
