Not too long ago, I got redeployed to the security division of a university in Florida and was tasked to take care of a system of cameras. Primarily, just what I have to do is monitor feeds from security cameras that are set up all over the school stadium, including those around the entrances and hallways. Considering that I had never dealt with surveillance systems which cover such a huge extent, I made a decision to know a lot more about them.   Surveillance systems generally consists of a number of video cameras plus a multiple-channel DVR. Such a DVR can hold from 4 to as much as 16 cameras. Given that all the video feeds are saved into it, this DVR connects all the footage in one structure for much easier viewing.   Some surveillance systems keep the video recordings on the hard drive of a separate DVR. Some other models can input the video footage at a built-in USB recording device.   There are those that have motion detection-enabled recording, which signifies that the DVR just captures motion to save disk space. This feature can even save me time in the future when there will be a need to play a specific recording again.   I also found out about two types of surveillance systems, wired and also wireless. According to the handbook, the university makes use of a 16 channel wireless DVR system. This setup was less costly since it was purchased as a set and it was simpler to set up, also.   A comparable monitoring system is further utilized at the university main hall and at the faculty building however I’m not assigned to those places.   Apparently, these kinds of surveillance systems chosen by the school management comprise of wireless cameras which are simpler to reposition and set up in various areas. wired cameras, that have nonstop power supply, are provided as well.   These color bullet cameras spread all over the university stadium are small and hardly obvious. Considering that they are day\/night cameras, they are great for 24\/7 surveillance and can record videos clearly even during evening.
