Cable over 300 ft?? Is cable messed up now from water??

[Treez 0]

Hello everybody. This is a two part question and I'm hoping some nice folks will help out. I'm just a property owner with a Swann DVR9 4200 and have tried to find a cable longer than 300 ft but Swann told me I could only use 300 ft at the longest. Is this true? If not, what cable can I use to have power and video that is longer than 300ft?

 

Also, I have a cable that shows great during the day but night vision is all messed up. I'm almost positive the water got in the connects of the cable because both cameras I hook up to it does the same thing and the same cameras are fine on another cable. Is this cable junk now? Or can I do something besides compressed air (I tried that) that might fix the cable?

 

I'd sincerely appreciate any and all help!!

Your DVR seems to be for analog cameras. So 300 ft can not be an issue, at all, in most of DVRs. But these days some DVR makers tend to use very cheap components that may deteriorate performances over a long distance cable. Make sure to Test and Confirm your cable before real field installation. Yes, the cable could be bad or of poor quality, based on your comments. Just in case, as to night performance, google "IR refelction or read some of threads discussed in this forum.

Thank you for your response! I'm not quite positive what cable I should get if I want a length of over 300ft, can you suggest a specific cable for me? Also, I'll take a pic of what the camera is doing at night time but I'm almost positive it's not "IR Reflection". You can't make out any picture at all, it used to work fine so I'm almost certain the water got in the connection. Should I through away this cable now or can I do something for it to work again? It's a 300 ft cable that I would have to throw away unless it's junk now. Again, thanks for your response!!

Most of cables are manufactured from China. I am not user or installer. But we have to buy cables on several occasions. It seems that the brand names can not be controlled or guaranteed. You better check out local dealers in your area. RG59 pure copper cable can go very long distance when compared to aluminum cladded.

Sunnykim, thank you for your replies. It seems as if you're the only helpful person in here and I thank you for that. This is a pic (1st pic) of what this camera looks like at night time. No IR reflection, I believe just a bad cable. It's fine in daytime (pic 2). Thank you.

And this is the cable in question.

The same video scene and the same camera on the same cable.

The difference comes from day & night.

But No IR issue, as said.

What's left?

Moisture at night leaks into the damaged cable?

Really no idea.

Thank you for your responses!

Any chances of electric power running short at night?

You may turn some cameras off just to test this

This happens recently?

No ma'am, nothing like that has happened. Tonight I'll unplug all of the other cameras and see if that makes a difference. I'm almost positive it was water that got into the connections. I wrap the connections up with a ziploc bag and tape it up real good but it's still not waterproof obviously so water probably got in. I paid $70 not long ago for this cable so I'm hesitant to junk it and buy another just yet. When I get a new cable I'll go about wrapping up the connections differently this time.

Get a good water dispersing contact cleaner spray. Pull the connections apart, spray, wipe clean and dry and try again.

 

A good way to seal is to use self amalgamating tape that 'melts' together after you tape it to form essentially a waterproof wrap.

I will do both of your suggestions, thanks a lot for the response!

RG59U Siamese cable can go much further than 300 ft.

[Treez 0]

Thanks for the response, Jburn. When I asked Swann before about RG59 cable they gave me an answer something along the lines of "sometime they work and sometimes they don't".

 

It sounds like if I ordered some RG59 cable I'd have to add some bnc connections to it? Or maybe a power connector? I appreciate any and all advice!!

And does it make sense to anybody that the cable would show day time but not night vision??

 

I thought for sure it was the camera that was bad at first but when I switched cameras with one that works great on another cable, as soon as night time rolled around it showed the same as the other camera. Both cameras show good on another cable but bad on this one. I figured it was the cable that was bad but why does it show just fine during daytime? Doesn't make sense.

Maybe because at night, the night vision is pulling more power than during the day. So for some odd reason, the more power being pulled at night on that cable is a bad combo, so goes back to the cable being bad?

Ok, thanks for the reply and explanation, badmop. I appreciate any and all responses!
