Plastic junction box water tight?

[aMike101]

I was looking at buying a junction box to make my IP cameras connections in to seal from the weather. The camera is on on a wood pole the junction box below it.

The junction box uses NPT 1/2 cable glands that is still to big for a single cat5e cable so how does one make it water tight? I can't find a cable glands 1/2 that goes down to the size of a single cat5e cable.

And if you go to small the network connector from the IP camera wont fit through the hole.

Suggestions?

I have found that you may need a 3/8" gland for a single cat5e cable. You may be able to find a 3/8" to 1/2" reducer to use that in a 1/2" inlet.

Alternately you can wrap the cat5e cable with a couple turns of self-sealing tape such as coax-seal to increase the diameter sufficiently for the 1/2" gland to then compress around.


Also don't forget that even with glands and every other bit of sealing you could possibly apply always leave a drip loop in the cable before it enters the box.

Many industrial electrical MFR'S make cord grips with all sizes of holes. Try an electrical supply house (not Lowes or Home Depot). They can usually fix you up with whatever you need in the size you need it>

I use coax-seal for that, but I don't understand why wasting a j-box on a single connection. The camera's waterproof connector works.

Not many here would trust just the camera's waterproof connector, especially if it isn't in a junction box or tucked back into the soffit.

Can the connectors be exposed to weather?

I bought a HIK DS-2CD2387G2P-LSU/S i mounted it temporary and have it powered by POE and that is sealed up tight using the waterproof connector but there is also separate wire for power and another for a alarm.....can't think of the name of them as i never use them but do they need to be water...

Cameras are not cheap a junction box is. I have had that so called waterproof connector get water inside it over time and short out blowing a pin off the cameras connector now i use that waterproof connector inside a junction box.

BTW does anyone know the pin out for dahua cameras?

Like others have said something like this in the correct size sounds like what you're looking for. Just make sure the connector is not installed on the top of the box.
