So I've been lurking and following the X-Sight saga here for about 12 months (thanks to everyone for the information and insights) and after reading the largely positive feedback on the 1.8.06.296 firmware, I decided to pick up a 5x X-Sight as my first venture into night vision and to have the ability to record within the scope. So far Iím running firmware 1.8.07.343 and I'm happy with it.
As other users are aware it is fairly power hungry as are most other digital NV units so I am playing with making an external power supply. So in aid of that, I decided to do some power measurements to evaluate what sort of runtime I could expect from different battery solutions.
The only other data I found on power consumption was the info here
, originally posted on a UK forum.
I decided to do my own testing with the latest firmware. All measurements taken with the X-Sight running off a 3V supply using firmware 1.8.07.343.
Standby Current: 150uA
Startup draw: ~535mA
On, Viewfinder brightness Minimum (WiFi off, GPS off): 1.242W
On, Viewfinder brightness Maximum (WiFi off, GPS off): 1.284W
Sleep mode: 0.924W
Wifi On adds 0.243W
Wifi On and streaming video adds 0.276W
GPS adds 0.186W
The low battery indicator comes on at 2.67V
The image degrades with noise at less than 1.96V
The scope shuts off at 1.91V
There is not any appreciable difference in power consumption between running day mode or night mode.
These results are significantly lower than the UK results (1.8W Wifi and GPS off, 2W with Wifi and GPS on), possible explanations are that there have been several firmware revisions (and possibly hardware revisions?) since Dec í14 when these results were posted, and also the test setup could have been different.
