Cat5 or Cat6

I bet your local telecommunication installers would. If you know the footage, probably get dirt cheap instead of buying a full box/full roll.

Where exactly on the cable/RJ connector do you apply the grease?

I should have clarified, but this stuff is useful for connections that are outdoors. Even with the "waterproof" connectors you can have some problems. You simply put a glob of it in the female portion of the RJ45 connection (camera side) and then plug the male into it. Your connection is now far more corrosion and water resistant. I've seen some photos of what happens when the corrosion sets in and it isn't pretty.

Who has the best quality and price for cat5 or Cat6 direct burial cable. Thanks

"direct burial". That's a new term to me. Keep in mind I'm a newbie to this so this isn't criticizing. Just asking for explanation.

I've heard "plenum cable" which I believe implies that its solid, not stranded and appropriate for walls/attics. I've also gathered that solid pure copper, not CCA (copper-clad-aluminum) is preferred but obviously more expensive. Stranded cables are more ideal for jumpers wiring at the switch or where you'd want flexibility but not mandatory. Whereas using stranded inside walls/attics is frowned upon.

anyone want to share knowledge for the group?
 
Direct Burial cable is a cable that is waterproof and the outer jacket is very firm and impervious to many things to a degree. If you want your cable protected in conduit or directly into the ground, direct burial cable is the way to go.
Plenum cable (aka CMP) is a cable that the outer jacket does not give off toxic fumes when burnt. Usually spec'd for hospitals, govt buildings, daycares, etc.
PVC (aka CMR) cable is what is installed 85% of the time. Standard indoor cable that will put off toxic fumes when burnt and not at all rigid or impervious.
I have seen installations where someone ran 200' of PVC cable in underground conduit (being metal or PVC pipe) to a destination thinking the conduit would be itself waterproof. Nay Nay. Direct burial cable even in conduit due to it's waterproofing ability.

It is rated for direct buried use. As in dig a trench, put wire in, cover with dirt. No need for conduit or anything. Usually it has a tough poly out sheath and then another inner sheath. Sometimes it will have a metallic sheath between them. Along with some type of grease or jelly

+1 to @Holbs last.
I might add you can, in a pinch, use the more expensive CMP (Plenum) where CMR (Riser) is suited but NOT vice-versa.

Also, he's spot-on regarding water finding its way into underground conduit....it's a fact of life.

and take into consider the $$$ amount. There is a reason why CMR is most popular...cheapest. CMP is nearly 2x's the price tag. Actually do not know the price tag of direct burial (boss man buys the stuff).
If I had to run cat5/6 or any low voltage cable in my house...I would go CMR. As if during a fire, I would pause and say "hay...that CMR is going to put off toxic fumes so I best get out" while the couch, carpet, etc puts out way more toxic fumes.
 
Never had an issue with non-burial. Can anyone show burial ones that are suggested? links.
 
first pic is direct burial. see the outer black jacket? it's firm and weatherproof with a green metal foil for grounding/lighting protection purposes. but yet, a shovel digging down could still nick the copper inside if strong enough.
second pic is direct burial armored. same as direct burial but with a substantial robust green armor shield.

Nice - how much is a good direct burial. I might try this if any issues with current setup running underground.
 
Regarding water getting into underground conduit (from my Dec. 2018 post):

"Water usually gets into "perfectly sealed" underground conduit by way of not-so-airtight, above-ground boxes: the sun heats the ground, the ground heats the air in the conduit, expanding it and pushing air out, the sun goes down, the ground cools which cools the air in the conduit and it contracts therefore drawing in the outside and moisture-laden air (it's after sundown) via those above-ground boxes, that air cools down inside the conduit, causing the moisture in it to condense and it travels to the lowest point(s) in the conduit run where it collects. Over time this cycle repeats many, many times and you end up with water in the conduit.

For this reason I have always used outdoor-rated, flooded-burial or direct-burial conductors in underground conduit. Water WILL get into underground conduit....just a fact of life."
