The cam will stream throughout your complete nesting season, in addition to the remainder of the 12 months so long as we’ve got the required funding to maintain the cam streaming.
64. When will chat be shut down?
The chat will shut on the finish of the breeding season.
65. What kind of cameras do you employ?
We use the AXIS Q6035-E PTZ Dome Digital camera and the AXIS P3364-LVE Community Digital camera mounted dome with IR Illumination and distant focus and zoom.
66. Why is the nest so vivid at evening?
The AXIS P3364-LVE Community Digital camera has an infrared (IR) illuminator. Many of the cameras we use are IR delicate, which means they’ll see IR gentle. IR gentle is to not be confused with thermal imaging. The cameras can see IR gentle mirrored off objects such because the nest, birds and eggs.
67. Does the sunshine disturb the birds?
No. Hawks can’t see infrared (IR) so the IR illuminator doesn’t disturb them.
