Thanks a bunch!I'd suggest Duct Seal instead of silicon seal. Duct Seal is an electrical putty that will remain pliable and can be removed, should it become necessary, should a need arise. You can pick it up at Lowes or Home Depot in the electrical department or from Amazon to save a trip to the store.
WOW! If I did that, I would be headed for divorce court. I have a wood stove in the basement, I remember cutting the floor for vents and yes It can get a bit hot at times. You in ways have given me some Inspiration running cams down my driveway and to the back of my property, Looking forward to seeing the final product.Installed 2" PVC pipe in floor for 6 cables. Overkill but never know when I want to add more cables. Used a hole cutter this time. Sprayed water with a plant mister while cutting since it smoked some. You really have to be careful when doing this. Sawdust, carpet underlay etc should be thoroughly sprayed with water - in the cut, under the carpet edge, down in the hole. Used slightly undersized round saw, then finished hole with dremel. Wanted the pipe to be tight. Last pic shows I almost made a few cables too short. Table was pulled away from the wall a coupe of feet and 2 cables came even to back of NVR.
Bryan I currently have 6 cameras installed in the woods with about 10 different IR sources on trees as well as 2 4port switches. The furthest run for me is about 100m but the loads are constantly changing as I add more cameras / lights. I run 48 volts out to the trees. There I use a 12 volt buck voltage reducers like this one:. . . The voltage drop on the 14 awg was enormous. will take about 18V to get 12V at the end. Couldn't afford 1000ft of 12 awg.
Sheeeit..that's a good idea. I've already installed 2 wire direct burial 14AWG and bought a cheap variable 12 to 24V power adapter at 2.5 A. Not planning to use anything but a 15 LED IR light and a mic, but if I had to ever upgrade that would be a big help. I have bought those DROK boards in the past for stepping up 12V car batteries to 19.5V for a laptop, and regulated 12V to my router from a car battery. Never had a problem. Thanks for the idea.Bryan I currently have 6 cameras installed in the woods with about 10 different IR sources on trees as well as 2 4port switches. The furthest run for me is about 100m but the loads are constantly changing as I add more cameras / lights. I run 48 volts out to the trees. There I use a 12 volt buck voltage reducers like this one:
Amazon.com: Down Voltage Regulator, DROK Car Power Supply Step-Down Module DC 20-55V to DC 12V 10A 120W Waterproof Buck Converter Volt Transformer Reducer Board: Home Audio & Theater
it's all of $18.00 and will provide 12 volts out up to 10amps with any input voltage from 20-72V input
To get the 48 volts I use something like this:
It's all of $21 and will supply up to 10 amps (480w)
What will that get you? Well, if you are drawing 2 amps on that 12 volt side there will be about 1/2amp draw on the 48volt side. If you use 18ga wire (assuming 1000' run or a total of 2000' of wire) the resistance ~13ohms. You will get a voltage drop in the wire of 13ohms*1/2amp=6.5 volts. So the buck device will get 48-6.5= 41.5 volts. Twice what it needs to operate fine. You could triple your 12volt load and still be fine. Plus you would probably save over $100 in wire cost.
The big advantage for me is having that 48volts out there. It gives me flexibility to extend my camera coverage. I already have 2 switches powered by 12volts mounted in the trees - and can add more. No need to pull any more cat5 wire.
I'm not retired and i still want cheap solutions.Working on junction box while weather is changing.. Yes I know I use cheap solutions..retiree.
I don't want to rain on your parade, Bryan, but moles dig near the surface when they're looking for food, and they eat a lot which means they dig a lot. They also dig tunnels, think freeways, down around eight inches to a foot to be able to commute to grazing areas. I don't know if they'll chew on wire/cable though.
I think I've seen those somewhere!
