The Z CAM is mounted in a rigid chassis which has three positions for the camera to allow for different lenses.
The assembled pod has six jacking screw points and a vent port to aid with disassembly. The vent port can also be used to check that there are no leaks the using the ROV vacuum pump.
The Z CAM is connected to the BlueROV2 Electronics Enclosure where it uses the spare wires on the umbilical. This is then split on the surface to allow the video from the Z CAM to be viewed via a second Ethernet port.
The live feed can be monitored using an Oculus 2 VR headset via the Virtual Desktop app. which also gives control of the camera’s settings while filming. With the headset on, there is no interference from the sun’s glare.
The view from the Oculus 2 is like being in a cinema, the interface to the ROV PC is via a app called Virtual Desktop which runs the client. I will do another post detailing the process.
I have attached a screenshot below.
The maximum depth depends on the materials, I use a PVC housing and an acrylic dome which should be good for 100m (I will run a pressure test before selling them). Then there is the length of the cable to worry about as 100m is probably the max if you want to view the output on the surface.
The camera can be controlled from the surface so the battery will depend on the amount of time you are recording, I am currently limited by the size of my CFast memory card as 128Gb lasts about an hour when recording 4K (305MB/s), I will have to invest in a 1Tb (£700).
