Looking for a Mast head camera

I have seen a thread on this but can't find it.

The purpose is to look for obstacles coming into new uncharted or poorly charted anchorages.

I'd like to permanently mount it at or near the top of the mast and see the bows and about 80 - 100m circumference. No need to move it. I'd like to hard wire 12Vdc and recive video wirelessly and display it on a Zeus 3 or ipad.

Does anyone have a suggestion for the type of camera I should use.

Re: Looking for a Mast head camera

I literally yesterday noticed two cameras on the solar arch of my friend's sy parked where I'm docking tomorrow. I'll ask him what he's using and take a pic because I was interested too....

Could you ask your friend how he keeps them clean? Seems a thin layer of salt would accumulate on them an make the video image poor.

Re: Looking for a Mast head camera

I have a HD camera on top of my mast and a PTZ ( pan tilt zoom) camera on the bow . Dedicated lcd screen ( than switch from top to bow camera) in the saloon with joystick to control the PTZ .
The angle of the top cam is important , I’ve set mine so I have a complete view over the horizon starting from 15 meters in front of the bow.
And no gentlemen , I don’t use the PTZ to spy on the neighbors wives :-)
Have the cams for about 5 or 6 years now , the top camera is mostly used on long sail stretches .
Regards

Re: Looking for a Mast head camera

The HD-Q7 is a 4-in-1 HD CCTV camera that supports the following video surveillance formats: AHD, HD-TVI, HDCVI, and analog CVBS. The AHD, HD-TVI, and HDCVI modes are 1080p resolution (1920 x 1080). The analog CCTV mode (CVBS) supports 960H resolution (960 x 480). Installers can easily select the video mode using the small joystick that is attached to the camera's video cable. The 3.6mm lens captures a 90-degree field of view. Check out these sample surveillance photos and video demo.

The HD-Q7 is enclosed in a white IP66 weatherproof housing which makes it a great choice for indoor and outdoor installations. The 36 infrared LEDs that are built-in allow the camera to capture video in normal, low light and zero light conditions. The tri-axis mounting bracket allows installers to ceiling or wall mount the camera and adjust the angle of view in any direction.

This camera is typically connected to a surveillance DVR by hard wiring it using the same RG-59 or RG6 coaxial cable that is used for analog CCTV cameras. If you do not need to record video and would like to connect this camera directly to an HDMI TV / Monitor for live view only, please refer to the AHD-CV7 AHD to HDMI converter, or select it from the drop-down above.

HD-Q7 Features
1/2.9" Sony IMx323 Image Sensor
1080p HD Video Resolution (1920 x 1080)
960H Resolution in CVBS Mode
AHD, HD-TVI, HDCVI, and Analog CCTV (CVBS) modes
Zero Light Infrared Night Vision
32 Pieces Infrared LEDs / 60 foot IR Distance
3.6mm Fixed Lens / 90 Degree View
IP66 Weatherproof Housing - Indoor / Outdoor
White Color Housing
Tri-axis Mount - Ceiling or Wall Mountable
OSD Controls via Cable / Joystick
DC12V 350mA
12V DC Power Supply Included

Re: Looking for a Mast head camera

Check for the refresh rate, as on the way the boat swings from left to right and slow camera will not upgrade important details. Eg - other sailboat/ship that is coming to your way... Usually regular security cameras waterproof or not - will not be up to the task.
On the slow and calm situation - almost all cameras will do.

Re: Looking for a Mast head camera

I've been thinking about something similar. Would the masthead camera need some kind of polarizing filter to reduce glare and see beneath the surface better? It would be very handy to have a forward-looking view to spot coral heads, sandy areas, see the color of the water to estimate depth, etc. It might be a very handy aid for navigating into unfamiliar anchorages, and with anchoring in general, particularly when solo.

ParrotHeed, did you plan to include a URL to a vendor or manufacturer? It would be very helpful.

Re: Looking for a Mast head camera

A polarising filter would, indeed, enhance visibility under the surface. But it may need a rotation control because it needs to be set at right angles to the perpendicular bisector of the dominant light source. Usually the sun, but possibly the moon or harbour lights. Anyone tried this?
A zoom lens would be good when anticipating a land fall. The extra hight would show land maybe an hour before deck level eyeballs would see it. The extra twelve or whatever meters would give, um, well, yes, there is a formula somewhere in a book. Fifteen miles?
Gimball mounting would keep the horizon level but not really necessary.

Thanks, can you see if they are wireless video. I can take power of the lights but I don't want to run a video cable through the mast.

These need a coaxial cable, I'm trying not to fill up the mast with cables when possible. Is it possible to get what I want with wireless?

Interesting to have thermal, I wonder if it would pick up whales a couple of meters underwater. Probably not but would see them close to the surface.

I would definitely want good quality colour images not like the security images you often see on the news. I imagine something high definition standard but not as wide an angle as gopro.

Good point, they probably do have polarizing lenses.






Also I found the old thread.... Masthead camera

Re: Looking for a Mast head camera

I was wondering about a drone camera... They are small, light but need a weatherproof housing. Maybe rig up a small solar panel and it should transmit straight to your phone/iPad.
I have looked around in a half-hearted way. They are gimballed, can be directionally controlled - but you always get a drone with them
Looks like a small but potentially viable opportunity for the right person.
