How a Home Security System is Set Up
[ad#block]Electrical Question: I bought some 5V Foscam Surveillance Cameras recently and had them installed. We tested the cameras and they were working properly when they were plugged in with original adapters. After they installed them, only 1 is working. I am pretty sure it is because they had to extend the power cord to the areas where the cameras are mounted. We tested them again, and when they are plugged in with an original adapter they work. Currently, the one camera that is working, is the one closest to the power supply. They people who installed them said that they tested the volts at the cameras and were getting 5v before the cameras were turned on. I have my doubts, but anyways, do you have suggestions as to how to solve this problem?

Thanks,
Kerry

Thanks for your electrical question Kerry

Home Security System

Surveillance Camera Power Supply
Kerry, each surveillance camera may be requiring its own separate power supply, and may to function if the power supply is shared by more than one surveillance camera. A power supply voltage level may drop down when the device is actually attached to the power supply, so the power supply must be rated to provide enough power for the connected device. To verify this you should consult the owners manual or the installation manual which came with the surveillance cameras. These manuals and all of the documentation should have been left with you, and the system should have been fully tested and functional by the installing security system contractor.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
