The SURVEYOR Moisture Alarm, Vacuum Valve & Pump for Canon EOS 5D Mark II from Aquatica offers an added level of protection to the underwater photographer. The SURVEYOR circuitry integrates a water detection function that remains on constant duty when a battery is inserted. Should the slightest amount of water make contact with the sensor probes, it will trigger an alarm using both an audible signal and a rapidly flashing red LED to visually attract your attention. Adding the vacuum pump and pressure valve to your housing will make it possible, by creating a vacuum inside the housing, to fully test its sealing integrity. Once the easy-to-follow procedure is completed, a green LED blinking every five seconds will inform you that your SURVEYOR system is monitoring your camera housing and you're ready to dive. In the event that sand, hair, or other foreign matter would compromise the housing sealing integrity, the SURVEYOR warns you with both an audible signal and a rapidly flashing red LED signal.

This kit includes the moisture and vacuum sensor circuit, a pressure valve with retaining nut, a vacuum pump, mounting hardware, a container of O-ring lubricant, and a CR2032 battery.

It only outputs 1080p even when in 4K Mode, but it retains the 1.74x crop while in this mode. I use an Atomos Ninja Inferno with mine. There are some menu settings that you will have to hunt for to enable this, but it is worth it.

Q: 9. is it better to have 45 pixels or 30 pixel for a camera?

A: If one is using the camera for video, the less MP(30) the better, cameras with high MP require much more processing to reduce the files down. The 4Kvideo frame is only 8MP a frame, and an HD frame is less than 2MP. If one is shooting still photos that will be blown up very big, and the photographer needs to crop down to a tiny section of a photo, 45MP is better.

Q: 10. I am looking for an HDMI cable for a canon 5d mark 4 that is usb-c
