Recording– Check if cams have a slot for an SD Card. Also find that you can preserve recording in the cloud or not.

Users Review About The Product

Socrates Garcia gives her responses as-

  • Excellent cam but only after you set it up. Do not mount it until you set it up for your DVR (use CVBS to setup first) and set the night mode to Auto. The paper that comes with it does not tell you. The included pictures on amazon gave me the clue. But once you set it up before permanently mounting it, WOW, the picture quality is amazing. 
  • I had to set mine up for TVI 4MP at 15 FPS to work. The limiting factor is my NVR, the cam can still go up to 5k so keep trying and save your settings before switching to your NVR’s supported camera mode. Do not change the camera modes with your DVR’s supported mode, looks like it must be set up using CVBS and then save the settings. 
  • Then switch the settings back after you select “save and reboot” unplug the power and turn it back on, now use the joystick and press for 5 seconds to select your NVR’s mode. Will buy 2 more since they are that good.

Jrod gives his opinion:

  • I love this varifocal camera for its price, quality, and features. I prefer this type of camera over the bullet style because you can adjust all the axis on a turret-style camera and you cannot do it on the bullet.
