How can I do a monitoring/guard CCTV camera effect like pictured below with blender? enter image description here

If you are trying to achieve this effect on the right:

before and after security cam effect

Use the compositor and distort the source image with a Lens Distortion Node in projector mode. This can make it appear like a fisheye lens. Security cameras have a wide field of view. You could add horizontal lines to simulate an old tube monitor screen. Use a wood texture node and scale the x axis to 0 and the y or vertical axis to a very large value, then multiply it with the source, after distortion.

Also security or guard cameras operate in low light so you could remove the color with a Hue Saturation Value node.

distortion and texture effect

scale texture for lines

For extra value you could add glare to the source image to blow out highlites and make a slightly blurry image, as these cameras often have poor optics. If you are making this effect in 3D I would still suggest using the compositor.

    @mobile_beginner_2015 You may add an addictional distortion effect to it like in here: http://blender.stackexchange.com/questions/33660/how-to-achieve-this-effect-screen-tearing-glitch-in-blender-and-what-is-this – Paul Gonet Nov 12 '16 at 13:53

    Thanks 3pointedit, this is indeed the effect I try to make – mobile_beginner_2015 Nov 12 '16 at 19:53
  • I'll up the anti... try generating a completely glitched piece of geometry along a roughly horizontal alignment. If it animates fast even better. Feed the normals to a displace node and intermittently glitch it, for that broken feed vibe, or do a vertical drag of the object to simulate a feed roll. – troy_s Nov 14 '16 at 04:03
  • You mean like this other BStack answer? http://blender.stackexchange.com/questions/33660/how-to-achieve-this-effect-screen-tearing-glitch-in-blender-and-what-is-this?rq=1 – 3pointedit Nov 14 '16 at 05:25
  • Looks like. I did it for some video footage ways back. You can do a bubble distort (squished horizontal isosphere) or jaggy glitch (spikey cubes, densely squished horizontally) etc. It is pretty great when animated, surprisingly. Oh and if you do it, post an animated GIF from here for example @3pointedit http://gifmaker.me – troy_s Nov 14 '16 at 15:30
