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.

    $\begingroup$ @mobile_beginner_2015 You may add an addictional distortion effect to it like in here: blender.stackexchange.com/questions/33660/… $\endgroup$

    $\begingroup$ Thanks 3pointedit, this is indeed the effect I try to make $\endgroup$ Nov 12 '16 at 19:53
  • $\begingroup$ 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. $\endgroup$
