Am glad to hear from you
You are amazing
I give God thanks
Then for mistake No 3: If the cameras are IP cameras you can use POE switch to repeat the network, thereby getting the distance required for the camera installation.
The moment you put in a POE Switch, it becomes a strategy at making sure you don't have a straight cable running through the entire 100m. What i have indicated in the video is having straight cables beyond 100m
For mistake No 3: I think using a video balloon is very necessary, because I have installed cameras with over 750m connected to the DVR.
If indeed you did 750m, you might have used 2 and a half boxes of the 305m cat 6 Network cables. Is that the case? Remember 100m is just like the length of a football pitch, are you saying you have run cables whose length is equivalent to almost the length of 8 football pitches put together lengthwise?
1. How did you deal with joints?
2. What is the video quality?
3. How was your power connected?
I will be glad to hear from you.

For the joining, I don't allow moisture in any joining I do because within a matter of time, I will rust due to the acidic content of rainfall, I will deploy 3 by 3 adoptable box for each joining, which after joining I put the joined part in a strong water proof because it cannot be degradable.

For the video quality that's why I used video balloon, this experience I got is from a military barracks where I installed cameras to a very far distances.

For the power connection, let me teach a little trick, the RJ 59 cable comes with a power and video cable, for the power aspect of the cable, I will use the other end in the control room to be connected to a 230v electrical socket, then convert it back to DC using a 12v 2ahms adapter at the camera end, problem solved, the most important thing is the power, when you use your multimeter in checking the DC volt and your getting 8, 9.5v instead of 11.5, 12v thats where the problem starts.
The second option is to increase the voltage ⚡ signal from the power supply to increase the voltage transmission due to the long range cable.
