If the proper power is not supplied to your CCTV equipment, it can cause it to lose signal or in some cases cause your camera(s) to fry!  Two essential things to consider include Voltage and Amperage (you also want to keep in mind loss of power like Voltage Drop. Below is a table for expected voltage drop based on cable used and distance

  24 AWG 22 AWG 20 AWG 18 AWG 16 AWG 14 AWG 12 AWG  
DC 100mA 216 feet 342 feet 594 feet 867 feet 1,379 feet 2,197 feet 3,508 feet
DC 200mA 108 feet 171 feet 297 feet 433 feet 689 feet 1,098 feet 1,755 feet
DC 300mA 72 feet 113 feet 198 feet 289 feet 459 feet 732 feet 1,169 feet
DC 400mA 54 feet 85 feet 148 feet 216 feet 344 feet 549 feet 877 feet
DC 500mA 43 feet 68 feet 119 feet 173 feet 275 feet 439 feet 701 feet
DC 750mA 28 feet 45 feet 79 feet 115 feet 183 feet 293 feet 467 feet
DC 1000mA 21 feet 34 feet 59 feet 86 feet 137 feet 219 feet 350 feet

That said, we wanted to share with you a quick reference guide and overview regarding the voltage and amperage that powers your CCTV security cameras.  Keep in mind, this is a beginner reference guide and does not take into account everything involved with CCTV camera power supply.  Each scenario is different, so to get a full understanding of the specifications you require, please give us a call and one of our knowledgeable representatives can help you - 1-877-926-2288

Most of the below data concerning voltage and amperage can be considered for 99% of systems.  Cameras will usually use either a 24VAC or 12VDC current. You can select by filtering out the voltage requirement at cctv power supplies section
