Are the cable connectors corroded/tarnished?

What is the voltage measurement at the camera?

I have used several Vitek outdoor vandal proof dome cameras and have been very pleased with them. I have not tried any of their bullet cameras yet so I can't comment on those.

The wire can be painted for protection from weather.

Lorex has a pinout of the DIN connectors on their website support section:

Hey!

 

Moved into my mates house few months ago. I've noticed he has cctv. I asked, "Does it work?" He said his brother set it up. It used to go into a box and come out of a small tv on top. Cut a long story short he has now gone and we have no box. What would the box have been? I know the cameras are years old. Have the connections changed? I'm good at building computers. Could I build one so these cables can go into it and record?? Any help would be appreciated, I'll upload some pics of what is here.

 

Those connectors on the camera cables are 6 pin DIN. The original system may have been made by LOREX. Lorex now makes adapter cables that adapt the old 6 pin DIN cables to use modern BNC or RCA connectors. That way, the existing cameras can plug directly into modern DVR systems.

Here are links to the two versions of adapter cables:

Several things to check:

Poor connections, maybe a bad connector either on the camera or on your cable.

Bad cable.

The power is too low at the camera (low voltage).

The switching power supply in the metal box can generally be repaired. They are just like the power supplies used in coin operated video arcade game machines. In arcade use, the power supplies have three output voltages, +5v, +12v, and -5v. In a security camera application for 9 cameras the power supply is usually a single output 12vdc @ 5 amps.

In general, the electrolytic capacitors fail most of the time. Replacing them usually gets the power supply going again. There are times where there might be cold solder joints, bad transistors, or bad diodes causing problems.

If you cannot repair the old switching power supply, this new one from Jameco Electronics should work:

Jameco's part number for it is 323599 and it's just $20.95

The Jameco supply is a "Mean Well" brand and it's model # RS-75-12 (12vdc @ 6 amps).

I used the # 3142 board from t-mart to repair that Q-See camera.

I just replaced one of those boards in an older Q-See box camera. The camera had been vandalized and the board was smashed. I went to t-mart . com and bought a new board of better resolution. That new board required me to solder it in since there were no cables with it. The connector pinout did not match the original, but hey, it worked and brought a camera back from the dead.

X2. You can not run low voltage wire/cable in the same conduit as high voltage or line voltage.

X3. That violates the codes.

In my local theaters, we use Sealtite conduit around the movie projectors. The projectors leak oil all the time and the Sealtite prevents oil from getting on the wiring.

Here is a link to Sealtite conduit:

Maybe you need one of those outdoor covert cameras hidden inside a security floodlight bulb? Or perhaps one hidden in a mailbox or a pinhole camera installed in the exterior wall?

A friend owns his own ATM in his business. It is a rear loading type that is built into a wall. I installed a bullet camera above the ATM for facial shots.

Radio Shack would also have fuses for that power supply.

In general, switching regulator power supplies will shut down if there is a short circuit or overload on it's output terminals.

I would think that by now most companies would have support for IE9. Granted, I do not like IE9 myself and don't use it. I've left all my computers with IE8 and only use that when I need to. Otherwise, I use Firefox all the time.

I'm surprised they just didn't use spray on contact cement to hold the camera in place!

Ground loop or maybe AGC problem/adjustment in the camera?

Yes, the 1/4"-20 thread has been standard in photography for like 100 years now. It is for mounting cameras to a tripod.

I can safely say I've never seen any of those movies and I have no desire to see them.

A lot of late model pinball machines use those blue tinted infrared LED's and phototransistors to optically sense when the ball has passed certain areas of the playfield.

I'm assuming this tinting filters out all unwanted light so only pure infrared light is emitted/detected.

What would I say to the guy?

"You've learned a valuable lesson today"

My Digital Labs 7" portable tv also has a built in rechargeable battery. It has a 2 hour run time. it has worked out very well for me in adjusting/setting up cameras. Heck, I even use it to test out new cameras straight out of the box so I can be sure I don't have any D.O.A. cameras.

I use an RCA to BNC adapter on the end of the AV cable that comes with the tv.

On an old J-Win JV-TV2040 system, they used the 4 pin DIN setup for their cameras.

Here is the pinout their system has:

1: Power (12 volt dc)

2: Ground

3: Video

4: Audio
