  • Huge field of view with ultra wide 2.10 mm focal length
  • Compatible with many EYESPYVIDEO.com cameras (see below)

  • 96 degrees vertical view
  • 160 degrees diagonal view
  • One of the widest fields of view available for EYESPYVIDEO.com cameras


The LS-21 (2.10mm focal length) can be used to provide an extremely wide field of view. However, the picture will have an "artifically" wide field of view with fairly severe curvarture of the video image. Unfortunately, there is NO way to provide such a wide viewing angle without this type of distortion.

This is a fixed lens with one specific field of view. There is no way to adjust the lens focal length for a dynamic viewing angle. For applications where multiple viewing angles may be required, please consider using a varifocal / zoom lens camera.

This micro board lens has a 12mm diameter thread mount, making it compatible with the following EYESPYVIDEO.com models: BW-4EX, BW-4LL, BW-4HAD, BW-4HR, BW-8HAD, CC-5EX, CC-5HR, CC-7HRM, CC-1SBHR, CC-8HAD, CC-8HR, TVD-CBHR,and TV-BCSHR. Because of its physical size, this lens cannot maintain the weatherproof seal on EYESPYVIDEO.com outdoor cameras and simply will not fit our camera models with built-in Infrared illumination.

The LS-21 has the absolute widest viewing angle of any "normal" lens available for our CCTV video cameras. The only wider angle lenses we stock are the LS-12 and LS-17. The LS-12 (1.24mm) has a tunnel-vision effect, and the LS-17 (1.70mm) is very large with a 'peephole' shape.

  • The new CC-5XDWDR Color Weatherproof Bullet Camera has incredibly clear 700 TV lines of resolution, Digital Wide Dynamic Range and 2D Digital Noise Reduction.
  • The wide dynamic range (WDR) function of a camera is intended to provide clear images even under extreme light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark. It also offers amazing low light capability.
  • Digital Noise refers to the random dot pattern that is superimposed on the picture as a result of electronic noise; the 'snow' that is similar to what can be seen with poor (analog) television reception or on VHS tapes. The Digital Noise Reduction feature reduces that "noise" from the cctv camera image.
  • This is the best bullet camera we have seen in terms of performance.
  • If you are installing a new system or upgrading an existing one this would be the best choice. It is cutting edge so you won't have to worry about having out-dated equipment 6 months from now.
  • Feel free to call us at 800-568-9291 for more information.
