Surveillance DVR NTSC PAL

This article will go over toggling the NTSC / PAL video setting on the iDVR-PRO video surveillance DVRs. NTSC is the video standard for the United States. Most countries outside of the United States use PAL video.

If you are getting the following error(s) on the iDVR-PRO DVR and are not seeing video, then most likely the unit is not on the correct setting.

Errors you will see:

"Error Invalid Connection SD(NTSC)"

" Error Invalid Connection SD(PAL)"

To resolve this, we will need to change the AC POWER Frequency in the iDVR-PRO system menu. Please follow the instructions below.


2. Now change the AC POWER FREQUENCY to 60hz (NTSC) or 50hz (PAL)

Security Camera System Quote

Did you know? CCTV Camera Pros can provide a complete surveillance system quote that includes any iDVR-PRO model with cameras, cables, connectors, power supplies, and monitors? We can even mix and match SD and HD security cameras because the latest iDVR-PROs are hybrid. They work with CCTV, AHD, and HD-TVI type cameras. As you have probably already seen on our website, we have 2, 4, 8, and 16 camera surveillance systems in pre-made packages. However, it is not possible for us to package up every combination and quantity of all the different camera models that we carry. So, we can also provide you with a custom quote with as many cameras as you need and a mix of any combination of camera model(s) based on your project requirements.
