Connection problem

[Raphaelmarting 0]

Hi,

 

 

I have a serious problem since too much time now, and i would be very pleased to have your comment and help if possible.

 

We installed 8 camera Bullet 4mp (From Qihan) outside in a factory.

Those bullets are connected to a PoE+ switch and connected to a 16ch NVR (From Qihan).

 

It worked during few weeks, but now I have always disconnection for two of those bullets.

 

Those two bullets are far from the PoE switch (Between 90 and 100 meters).

I used cat6 UTP (cables are outside the factory)

 

So now sometimes it's working and sometimes i lose those two cameras.

 

Do you think it's a cable problem ? should i use Cat6 FTP ?

Is it a problem because cables is too long ?

Is it a camera problem ?

 

What would be the solution

 

I'm lost and my customer start to be mad !

Thanks for your help

 

Raph

Hi. You are at max limit for your cable which will give you drop out.

And Poe might also be at its limit

 

I would move your cameras if you can to around 85

Or drop the Poe at the nvr end and install a Poe switch around 60 70m
