Page opened on Sat, 25 Feb 2017 06:15 in New York State in the USA, where the turtles live. If the picture is dark, then it's night time here. Turtles are diurnal, which means that they sleep at night just like people do; so the tank lights are on a timer that turns them on and off to simulate daytime and nighttime.
The box on the top of the habitat is a home-made basking area, but the turtles are still too small to easily see them on the video feed when they use it; so I re-aimed the camera to focus on the tank. You can find pre-recorded videos of the turtles from other angles, including underwater footage, on this page.

This turtle habitat uses a glass aquarium, which is the most common way to keep aquatic turtles. It uses Flourite as a substrate (which the turtles seem to love), with some white gravel as well. It may or may not have some plants in it depending on whether the turtles have eaten them. It also may have a few feeder fish swimming around from time to time. The turtles get live fish as a treat sometimes!
If the water looks cloudy, it could be because there's medicine it it for the turtles or other creatures who live there. Many aquatic medications make the water look cloudy or yellow. When the treatment is done, the cloudiness can be cleared up with water changes and by putting activated charcoal in the filter. It could also just be dust raised from the substrate by the turtles' digging.
If the tank is dark, it's because it's night time. Turtles are diurnal animals like we are, which means that they usually sleep at night, and they need light / dark cycles. So the lights get turned off in the evening, and then it's too dark for the camera to work. There's a blue night light that provides barely enough light for the camera to work, so you probably still won't be able to see them even with the night light on. If it's dark when you try to watch the turtles, just try again when it's day time in New York.
Although the exact equipment may change from time to time because of seasonal changes, health issues (sometimes turtles get sick and need the temperature raised for them), and other reasons, the basic setup that I usually return to when everything's back to normal is as follows:
The older turtles who used to be in this tank were moved to separate, larger habitats when they outgrew the tank and stopped getting along. It was easier (and more fun!) to get new yearling turtles for this video feed than it was to move all the video gear to the room where the other tank is, so that's what I did.
