Using Them In The Wild

If you are wondering what a CCTV camera installation looks like at a commercial scale, the CCTVcamerapros.com site has detailed one of their installations. They write that some of the specific requirements included the ability to record video and audio from six separate medical training rooms and have it be ported to a central location or monitoring room.

They also wanted the ability to be able to display live video from each of the rooms to a separate and dedicated computer monitor inside the monitoring room. Further, they required that extra monitor be used solely to display multi-camera views.

Another important requirement for them was that they needed the functionality to be able to log into the system over their personal business network to be able to view the cameras and also hear audio.

One final requirement, that was a little tricky, was that this university system wanted to be able to get live audio from their dedicated monitors, they also want to be able to plug in headphones and tap into the individual audio of that particular camera's view.

The CCTV camera installation specialists got to work installing CCTV cameras in the ceilings of rooms with 2.8 mm lenses for high-quality and wide-angle views.

They also began installing stand-alone surveillance microphones in the ceiling tiles of specific rooms. They used an 18 channel and 12 volt DC central power supply unit to provide power to all of the different microphones and cameras. They used pre-made Siamese cables to connect between the video cameras.

The dedicated displays were built out using 19 inch computer monitors. And a high-tech CCTV DVR was used to enable the video recordings. Display monitors were then connected to DVR displays to enable multi-camera CCTV camera views.

And all of the audio output of the dedicated monitors was then split and input into DVR audio inputs as well as the plate-mounted jacks to enable headphone connections. A tricky install, but one that the end user was evidently satisfied with.
