Hi @mat200Welcome mdm,
Congratulations you've done a great job - everything off hand looks fairly good.
PAL will be fine. Doesn't really seem to matter much with IP cameras.
I have read here that BI does not take advantage of additional graphics cards - just the chip instruction set in i5/i7 - thus why the CPU is so important. Thus you can save some money by not getting the graphics card.
NO Cat5. Cat5e OK. Cat6 better. Recommend Cat6 in general as the price different is not so much compared to cat5e - and if you are only buying 1 box you may want to use it else where.
Clip of my notes from SD wiki:
Lorex / Dahua OEM 6x 4K / 8MP security camera system w/ 8 port POE IP NVR 2TB HDD kit at Costco B&M YMMV for $799.99
Cat 5e / Cat 6 ethernet cable:
DO NOT buy CCA (Copper Clad Aluminum) wire - it is a fire hazard
- Recommended that you buy buik cat5e/cat6 cable and not use the cable which comes in the kit, as if you need to return it you will have to also return the cables.
- Recommended vendor for bulk Cat 5e / Cat 6 cable is monoprice, they often have sales during the weekend.
- Either Cat 5e or Cat 6 cable will work with these cameras. Normally Cat6 cable is a bit thicker due to the plastic separator in the cable. Also Cat 6 cable often has wires slightly thicker than what you see in Cat 5e cables. While a thicker copper wire means less voltage loss over the run, it may not be significant for most of us. Note the spec for ethernet and PoE is 100M / 328 feet.
- If you are pulling multiple wires through 1/2" EMT pipes or other tight spots it maybe better to use cat 5e.
- If you are only buying one bulk box of cable you may want to get cat6 in case you would like to wire up other locations.
- There are numerous types of Cat 5e / Cat 6 cable, you want to get Solid unshielded cable, either for in-wall installation or plenum rated cable ( better for multistory buildings and business type buildings ).
- If you plan to have the cables exposed to direct UV get a UV rated cable, or place the cable in conduit. Otherwise the cable will degrade over time.
- Also get RJ45 ends which are rated for solid wires, as well as a crimping tool.
- Remember to cut the cable longer than you think you will need, and leave some extra length in case you need to adjust the location a bit.
- Recommend pulling N+1 or more cables to each location, where N = number of cameras you plan to have. This way if you decide to add an additional PoE or ethernet device nearby you can in the future.
- If your attic is too short to easily work in recommending using Grey PVC pipe 3/4"+ and pushing the sections to the locations you want to run the cat5e/cat6 cabling to.
- Have a friend help you pull the cabling so you can reduce snags and knots which may cause breakages. Also remember not to pull the cable with too much force as it is more delicate than electrical cables that you may be used to pulling.
- You can use the pull tools which electricians use to help with the wiring pulls.
- Unshielded vs shielded cable - typically you can avoid using shielded cable, just try to keep the cable 1 foot or more from electrical lines, florescent lights, and electrical motors. If you must pass by something which produces EMF / electrical interference you can use a section of EMT pipe in that location to pass the cat5e/cat6 cable through.
- Thieves have been known to cut telcom cables to houses as well as cat5e/cat6 to cameras - if you feel the need to protect your cables do consider putting them in conduit or run the lines inside the wall. ( Metal EMT works well in most cases, in humid environments you may want to consider less strong non-metal conduit. )
Fancy tools for wiring
Drywall holes fixing
What about Cat6a? Does it perform better over longer distances or is that a myth? I have a few runs that seem long to me. It looks like most I've read say problems beyond 300M. Is that the distance from cam to switch or total distance all the way back to the router? Would my proposed setup work with 6a? Thanks again.
