Best way to boost Analog CCTV cam signal - 1000' RG59 cable

Recommended Posts

Hi ,

 

Having a cam at a gate that is 1000' RG59 cable with 2 splices

 

Signal is too poor at the DVR and cable is underground.

 

Any way to improve this ?

Hi is your camera 12v ?

26VAC & 12VDC

 

It's now connected to 26VAC

 

 

Hi . Then I would use a bi-wave.2100/2200 .. I have never had a problem using them over that distance

 

Video - power - audio or PTZ control over 1 coax cable.

You will need to put 12v to cam not 24v

Toss , When you said measuring the resistance to check the join , what reading should I expect and how to do it ?

 

-Should I measure the DC resistance with a DVM ?

-Or the impedance in AC , how ?

-Connect a load at one end and measure at the other end ?

 

 

Tks !

1) short inner to outer at one end and measure DC ^ at other ( return loss )

You will need to know your cable type/specs which may present a problem if it's not your cable and has been buried

Tks !

 

For a burial 1000' RG59 (inner 20AWG solid) with braid 95% , what would be approximately the resistance ?

 

Possible ~41 ohms over 1000' ?

 

Possible 10dB loss on 1000' ?

It is hard to say without more info. If it is 20awg 95% "pure copper" then 41^ seems a bit high. The 10dB loss would depend on what frequency it is measured. If you swept a cable from 1Mhz to 1Ghz the attenuation would vary from about 2dB @ 1Mhz to 40 dB @ 1Ghz over 100m
