Hello. Available SUCH camera. In Ladoga, you can't see anything under water. In this form, the thing is completely useless. There is a great desire to see the underwater world of fish in winter.
1) What should you install an open-frame camera with the minimum sensitivity? 2) And how to increase the illumination of infrared LEDs?
Or suggest another solution.

In fact, no matter how much I read about these IR diodes, I realized that they sometimes interfere with the camera ... so to speak, they light it up .. Therefore, given very good camera characteristics (minimum illumination, resolution and CCD matrix), on the contrary, I would turn off these LEDs or leave a couple of them ..
That's right, I want to cram a new camera into the old case. There is no description of the camera. This is problem. I don't know which camera is worth. No feelings, no suites, nothing.
= Almost any car rear view camera with protection will work. = They are all colored.... And I have a pipe screen. Or FSUs. It would be nice, they are cheaper than bodyless cameras. 600 lines and 0.001 lux costs like an airplane. I would like something cheaper. Can I put a color Z / H camera? I am looking at such , and such cameras, with IR illumination.
There is complete darkness under the water. Without backlighting, I think it will not work. With the old camera about 30 centimeters it was visible and very bad.

, in the cold it dubs but in the water it should be normal? What do you think?
The insulation will break before being immersed in water.

I tried to put a piece in the freezer for half an hour, took it out and sharply bent it in different directions, the insulation did not crack, until I stopped on it, googled it, they mainly use the KMM 4x0.12 wire, looked at Escor's website 26 rubles per meter.
I began to slowly collect, sealed the glass of the protective casing, first glued it, but the water leaked out, right now I missed it with black silicone sealant, I lay in the pan for a couple of hours, everything is normal, right now I missed the rear of the camera where the wire comes in, it dries. I made a stand so that it lay flat on the bottom of a copper wire, it is also necessary to place the weights evenly along the rectangle.
The monitor will be from a navigator-recorder, there is an AV input and recording on a flash.
Who cares I can upload photos of my attempts)
Right now I got confused over IR illumination, bought 6 pieces in Escor, they calculated the resistance for each, because they are 3 volt and the power will be from a 12v battery for an uninterruptible power supply, in short they are heated very much that the finger does not tolerate and the smell goes)))
Well, and the casing itself, made the chassis, taking into account 130 drill, a loop from above for an even vertical lowering to the bottom, and so that the wire does not hang out, otherwise the water will leak out)

In general, I will upload pictures of the assembly in stages, there is little time, there is even less money for parts)))
Today I found a plug for the navigator 2.5 mm 4-pin, it’s just this kind of input that will be shortened, hooked up on snot, it works, just didn’t figure it out so that the recording on the flash drive was going on, there may be such a moment that when the rear view camera is turned on, the recording will still be to go with the main one, and this is sad, it will not work to share the underwater world. In general, I will understand.
In the evening I will start assembling IR illumination, bought 6 diodes and resistance to them. The old ones I took before I burned)))

I am toiling with the choice of cable, thinking about taking a regular twisted pair cable for the internal connection
Then for outdoor. Street vitukha with black insulation.

Then for outdoor. Street vitukha with black insulation.
I felt it, hard strongly, twist it with a diameter so that it would be difficult to fit into the suitcase) The best option is KMM 4x0.12 everyone uses it and is happy, they even order it from other cities. Denyuzhka will be changed from twisted to it. Here you need to be strong and flexible but not strong, otherwise it will be difficult to orient the camera at the bottom. Those who have it ready from China with a thin wire are faced with this.
And I took the twisted one because of the number of wires, I want to turn on the IR illumination separately, if it comes in handy at all, I would like to make another type of water sensor. Experiments in the bathroom will show)
He went to the darkest place - the bathroom))) but while without water, you still need to seal the thread
The light is off the door is ajar-twilight
IR illumination is on, the difference is small but there is less noise
Well, that's all, the baptism of fire in the bathroom was successful, it remains to mount everything in a suitcase and buy a 7 amp battery.

I'm also thinking about a homemade camera! Because funding is limited, but there are various devices that children are already playing from being unnecessary!
Disassembled digital camera:
If you protect the lens from moisture, for example with a bulb, it turns out very convenient! remove the lens from the digital camera and the cord into the water, fotik with the monitor in hand! but 2 loops of 24-26 contacts go to the lens, it is very confusing to solder everything in 2 directions, I did not find a circuit, but I can not ring out where the video signal and power supply, there is no equipment!
Disassembled an old Chinese tablet:
the cable to the camera has about 12 contacts! I think to solder in both directions and test, but everything is very delicate there - it's difficult to do it manually without proper equipment!
Ivan, tell me which cable is better to take !?
And I'm still thinking about such a device with Ali?
in my opinion, and cheap and angry and easy to use, it connects to a smartphone, which is always at hand !?

... The fact is that for the growth of willow wires it is not a fact that it will work, because .k the signal is digital and there will be a loss, you will have to take a video amplifier, a bunch of problems. it is easier to buy a navigator or a monitor for a second-hand rear-view camera and a b / w camera is the most budgetary option, the main thing is the sealing of the case, a lot of useful information on the background.
Fishing technology in winter has undergone a number of changes lately. In addition to improved equipment, new methods of detecting the presence of fish have become popular - underwater cameras.Factory models are compact, easy to use, but have one drawback - high cost. Therefore, attempts are being made to make such a device with our own hands.
For design and DIY manufacturing, it is recommended that you investigate a suitable factory design. It is not necessary to exactly copy all the elements - the underwater camera can be adapted to suit your own requirements. It is important to decide on the maximum drop length, image quality and sharpness control. The cost of the structure will depend on this.
The camera should consist of the following components:
Camcorder. It is optimal to use a special one designed for diving to great depths. A budget option is to buy a car rear view and make a sealed case.
Monitor. You can also buy a car, since there is a large selection in terms of size and quality.
Cord for connecting the camera to the monitor. Its minimum length is 3 m.
Ice fishing rod, reel and line. With the help of these devices, it will be easy to control the position of the camera in the water, change the depth, and quickly get it out of the reservoir.
This is the best configuration option that can be supplemented with various gadgets. These include LED illumination, simultaneous use of the echo sounder. In the latter case, the likelihood of catching large prey increases.
You can purchase components at the nearest radio market, in specialized car dealerships or on a well-known Chinese online trading platform. In the latter case, you need to take into account the delivery time and the impossibility of checking the quality before payment.
Recommendations for the selection of components:
Monitor. You can take a car with a screen size of 3.5 “. The preference is given to models with a fastening element - a platform.
Camera. You can also use car, rear view. By default, it has a waterproof case, which can be improved by making an additional box. But this is done only in an extreme case, as the image quality decreases.
Cord for connecting the camera to the monitor. Its minimum length is 3 m. This is an ordinary three-core cable.
Battery. Small in size, characteristics are selected according to the parameters of the monitor.
The average cost of components is from 3000 rubles and more. You can take used models, but with a preliminary check of the operability.
It is imperative to check the possibility of joint use of all camera components - the way of connection, the presence of connectors. In the first case, choose a model with classic "bananas" - three veins of different colors. It is not recommended to use complex types of connection, as there will be problems with the tightness of the connections.
Connect the video camera to the monitor. This can be done using soldering or mechanical clamps. The joints must be insulated to prevent moisture ingress.
Battery connection. It is important that the power supply voltage matches the monitor.
Installation of the structure on a mobile stand. The latter needs to be made heavier in order to prevent its displacement with a strong current of a river or reservoir.
System health check.
The assembly process with all the components and consumables available will take no more than 1 hour. Beforehand, you can lower the camera into a filled bathroom or other large container. The image quality is checked, the absence of interference. They can occur with poor-quality contacts.
Before making your own camera, it is recommended that you familiarize yourself with the video material, which provides practical advice:
Such cameras appeared quite recently, and managed to find their buyer in the person of fans of both winter and summer fishing. Underwater fishing becomes more interesting and engaging.Naturally, not everyone can buy a camcorder for underwater shooting, but making it yourself is not a problem.
Since this product appeared on the market not so long ago, its price is quite high. The high cost of any fishing tackle pushes anglers to find simple and cheap solutions. The same can be said for the underwater ice fishing camera.
These people (fishermen) are considered to be quite enterprising people who are able to find a way out of any seemingly most desperate situation. They began to make similar structures from more affordable and cheaper elements. Such designs are in no way inferior in their functionality to industrial designs, but they are ten times cheaper.
As practice shows, there is nothing complicated about it. The main thing is the presence of all the main components, without which the camcorder will not work underwater. To assemble it, you will need the following components:
