Dahua has a new water proof junction box PFA130-E / PFA130E for Turrets ( PFA137, PFA139 )

Looks like Dahua is following @TechBill here, as he made a cover for the junction box earlier this year!

I don't see no royalty check in my mailbox! :( Naw, I am glad that they finally came out something to seal the junction box better. I wonder if I can just order a couple of the middle seal to use on the house exterior so I don't have to custom make it for each camera I install.

Anyone gotten this junction box yet? If so, will you take a picture of the middle seal itself out of the junction box so I can see how thick it is or if it have a grommet that seals around the box.

Thank you
Bill

Hi TechBill,

The middle seal looks like the same one from the PFA121.

iirc it is about 1" thick, with a hole and slot cut from the middle hole to the outside circle to allow you to put a cable into the hole.

Yes, I have one of those and already thought about that but the glue won't adhere to the junction box (using PVC conduit).

I realize this thread is over a week old but I just read it.
You can buy a 1/2" or 3/4" solvent weld PVC to EMT (male iron pipe) adapter at all home improvement stores as shown below. You use a conventional metal conduit lock ring to secure inside, then glue the PVC. This way you can use the stepped drill bit (Unibit) as @looney2ns suggested. They make nice, clean holes in PVC or cast aluminum.

Thanks for the reply. I wondered if they made something like that but didn't search for it since the install won't happen for a little while. Actually I will probably go with EMT since the boxes will probably be next to each other. If they will be further apart I will probably get that fitting.
 
this is a new one. I booked some. Can sell 2 weeks later I think.
 
I have used weatherproof boxes from Home Depot many times with rubber seal. Harbour freight has step drills cheaper then big box stores. I have taken a drill bit 1/4" and reamed slots in the bottom for wires from the camera to slide in and room for 4 network or BNC connected cameras in the 4x4x2" boxes. Run 3/4" pvc through house to basement to a 90 elbow with access to run wires easily. Couple pictures of how I found to be a decent setup and I have also screwed 1 camera to the cover of the box with hole bored through the lid for camera wires to go through

Remember to install drip loops for wires exposed outside.

Is the connection from a pipe to the box water-tight enough to have the pip enter from the top rather than the side or bottom?

Hi Mr_D,

The chance of that would be completely dependent on the quality of the installation and sealant / parts used during the installation - as well as how well the final installed product weathers over time.

In other words: Possible - Yes, Would I have hired help do that sort of work - No, too risky.
 
One of the best weatherproofing methods I've seen is called "Duc Seal". It's a grey, putty like, product that will adhere to conduit/boxes/cables. It's typically used with power entrance cables, for example. Just pull a piece off the "pug", roll it between your hands to make a rope, then press it firmly into position. It stay pliable for years, as in more than 20, and will keep most any joint, that doesn't move, water tight.

Perfect! Was looking for something like that to seal the air gaps within the conduit I have remaining going in from the attic to my closet. ( I have a short conduit section which I routed the cabling through into my "data center" closet )

Glad it will help. It can be removed and re-installed, too, which is handy at times. I've been using it since the 60's and it hasn't failed me yet. I think it'll act as fire stop as well, but don't quote me on that.

That is why in the pictures my wires enter the bottom of the box. No drip loop needed. I always did drip loops when I was with the Phone Company so water didn't follow the wire

They're good, too, but the advantage of duc seal is that one size fits all.
 
I find the glands are ok with cat5 wire and maybe some other. Bad part is the camera ends don't fit through the hole in glands. If they made a nut that split that would be nice. Camera ends for network cameras are about the same as BNC ends just fit through the hole in the glands
