New Installation Questions -- Cat5 Splice, IR Illum, Etc

[lely09 0]

1st Question:

Putting together a project and have run into several questions seeing if anyone has some insight. The home (aka project location) has been prewired with RG-59 and Cat5 runs to each camera location. Unfortunately one of the locations isn't long enough to reach the location where the camera needs to go. Does anyone have any suggestions for splicing? I was thinking of adding an outdoor box making a connection on both old and new cat 5 ends and coupling them together.

 

I was going to then use a video balun for the CMB Monalisa analog that I'm throwing up there. Can Cat5 be put right into an altronix power supply (the power wires i mean not the ones connected to the video balun)? If not how do you power it up if the camera isn't a POE.

 

2nd Question:

How many things can you power on one cat5? I will also be mounting several IP cameras with heaters, an IR illuminator and running video from each IP camera. Will one Cat5 serve the job or do I need to run 18/2 for each "extra" thing ie.. heater, Illuminator, etc.

 

3rd Questions:

Has anyone done online backup of an analog DVR? Essentially the purpose would be so that if say the location with the physical DVR and it's internal hard drive where removed or in some way perished there would be a second cloud backup of the information.

 

Thanks everyone in advance for all of your insight and knowledge

 

Cheers!

I just use "beanie" crimps to splice Cat5e for analog. It doesn't have to maintain perfect twists all the way through.

First, keep in mind that PoE means "Power over Ethernet"... with an analog camera, you're not using ethernet. Cat5e does not equal ethernet.

 

The baluns you can get with RJ-45 jacks usually use the brown pair for video, and the other pairs for power, separating them out into a pair of red and black "tails" for easy connection. With straight passive baluns, you can just split out the pairs you want for power and video and connect them whatever way is most convenient - run them into the power can and then extend the video with RG59 patch cables, or run them to the DVR and then extend the power with some 18/2 or station wire, or separate out long sections of the Cat5 and run each pair straight to where it needs to go... or whatever. We've recently been running the cables past the back of the DVR on their way to power can, then slitting the jacket close to the DVR, extracting the blue wire (our own standard for video), connecting it to the balun there, and then strapping the balun right to the outside of the wire to keep everything tidy. Done this on the last three sites and it keeps things really clean.

With IP cameras, you either want to use PoE, or run separate power. You don't generally want to be separating out pairs for power yourself (it CAN be done, but it's not recommended).

I am needing some of the same info.

Run power on cat 5 seams ok but IR Unit Hmmmmm

Need to look at what camera pulls for example 700ma

and what IR unit pulls 1 or 2 amps.

I have been thinking about laying out a test and checking it.

Cat 5 burns up easy, just look at what it did to i think it was the MGM casino fire.

Seams like i always have to go back to 18-2 so i can power long runs and or camera with IR unit.

 

Question 3 is do like the dispensories do. Use a single channel server to record 1 camera on the DVR off sight, then you will see who tampered with it, stole it, whatever. Law says they have to keep 3 days of video off sight.
