Due to the optical zoom, it is also possible to clearly capture images of objects about half a kilometer away.  In addition, having a CMOS sensor, it is able to detect distant moving objects and take high-resolution images.<hr>

 These are called PTZ (pan, til, zoom) cameras.  This camera can capture video up to 360 degree angle around.  This means that if a video is captured at a certain angle, its image can be viewed up to 360 degree boundary in all its right, left, upper and lower places.  Not only that, if the camera has a tracking sensor, the movement of something can be captured automatically.  This means that if someone makes some movement in front of the camera of this technology or if someone walks, the camera will follow him and rotate automatically.<hr>

 Zahirul Islam, owner of PC Net Computers, said that they are selling UNV PTZ Prime category IPC6222ER-X30-B model camera at Tk 45,000.  It is a CCTV camera with the latest security technology.  This high resolution camera can hold video as well as audio.

 As a modern form of CCTV, fishy cameras (fixed cameras) are used to view more places.  In addition, there is a dome camera (moving camera).

  The footage was captured on a mobile phone from a police cyber forensic computer monitor.  A few officials were reviewing all the footage of Iqbal's movements on a computer.  At this time, he captured the footage from a monitor on his mobile phone.<hr>

 If you look closely at the published footage, you can see the black border of the computer monitor around it.  And at the bottom of the screen, the menu of video player software is visible.  The footage was zoomed and played during the analysis in the forensic lab, so that Iqbal's movements could be clearly captured.  High-tech CCTV camera footage has made it possible to zoom in this way.

  The 360-degree angle footage was being verified from various angles by zooming in and zooming out on the forensic lab computer.  At this time a person holds it on his mobile phone.  The camera has 360 degree angle footage so it can be zoomed in and the position can also be changed.  There is no reason to edit the video here.
