ZoneMinder with Foscam C1 Cameras

I recently had the task of setting up a ZoneMinder server on Ubuntu Linux to record motion events from three (3) Foscam C1 V2 cameras. The instructions online for these cameras on the ZoneMinder website did not work for me, so here are the settings that ended up working for me.

First off, the settings on the ZoneMinder website say this:

———————-

General

  • Source Type: FFmpeg

Source

  • Source Path: rtsp://<user>:<password>@<ip>/videoMain
  • Remote Method: RTP/RTSP
  • Target Colorspace: 32 bit
  • Capture Width: 1280
  • Capture Height: 720
  • Deinterlacing: Disabled

———————-

However, when I choose source type: FFmpeg in my version of Zoneminder (1.30.2) the Remote Method options are only:

Note, RTP/RTSP, as the instructions suggest, is not an option. The correct option, as the images below show, is TCP.

———————-

In order to get these cameras to work in ZoneMinder, first, in the camera admin GUI go under Network –>Onvif.

Enable Onvif and specify your RTSP port. For this example I used port 1010. I was using multiple cameras so I used ports 1010, 1011, and 1012. Use whatever you like. Next, here are the settings in ZoneMinder that worked for my setup with these Foscam C1 V2 cameras.

Of course, replace the Source Path with your login information and RTSP port. The correct format is

rtsp://<user>:<password>@<ip>:<rtsp_port>/videoMain

If after following this guide, ZoneMinder is only displaying a blue screen when viewing a camera or ZoneMinder is not communicating with the camera(s) properly, update the firmware on your cameras, reboot the cameras and restart ZoneMinder.

I hope this helps!

 

Acoustic Research AR Model R Repair

Today we had the pleasure to bring this beautiful Acoustic Research – AR Model R back to life. This is a 60W per channel unit that was built in the early 1970’s and was one of the first direct coupled solid state amplifiers.


Our customer stated the main AC fuse would blow as soon as you turn the unit on. Upon our initial diagnostic, we discovered the main power rectifier diodes in the power supply were damaged. One was split it half, one was blown to who knows where,  and the other two were dead shorted. These are 3A 200V diodes so this unit must have been hit with a fairly significant surge, or something in the power supply section was shorted.

We replaced the four rectifier diodes and thoroughly tested all other components in the power supply section. To our surprise, all other diodes, resistors and capacitors in the power supply section tested OK. At this point we examined the rest of the unit and touched up several solder connections. The amplifier protection fuses were still good so it was our assumption that the amplifier section had no major issues, but we tested it anyways. Everything was well within specs.

Now it was time to power up! We replaced the blown main AC fuse with a 4A fuse and then slowly brought the unit up to 120V AC using a Variac. We hooked up an input source, some speakers, and had sound output out of both channels! The controls were extremely scratchy so they all got a nice bath in DeOxit. The quality of sound that this unit produced was amazing.

The unit now works 100% and our customer is happy to have it back in a working condition. For more information on the Acoustic Research model R, click here.

LED Strip Repair / Replacement

One of the most common issues televisions have is having sound but no picture. This can be an issue with the LED back lighting of the TV. While a single LED can last quite a long time, LED strips can still fail in newer televisions, causing your TV to not function properly, or the screen to be dim in areas. We can usually repair this issue! By replacing the damaged LED strips, we can have you TV working like it was new. Please contact us for more information.
