CCTV Surveillance Lens Chart

CCTV Surveillance Lens Chart

CCTV Camera is about clear picture; this clarity in image or picture captured depends upon its resolutions power, Lens etc. Different Lens and resolution capture image or picture in different way and mode. While selecting CCTV Camera one should focus on security camera’s resolutions & lens. Get information below about “Resolution & Lens”

Lines of Resolution:

Everyone while selecting CCTV Cameras focus on quality of video & image produce by security cameras. Every camera performance varies; this is based on number of horizontal lines. This horizontal lines is the chip in the camera provides is variation in performance. These lines help each CCTV camera to produce high quality video; the higher the lines of resolution the better will be video quality.  

Performance Color Black & White
Standard 330 Lines 380 Lines
Medium 420 Lines 470 Lines
High 480 Lines 580 Lines

Lens:

The lens determines the field of view the camera provides. Lenses range from 2.8mm to 18mm on an average. The larger the lens size the farther it will view. The draw back to a 12mm or 18mm lens is that the horizontal view narrows to as little as 15 feet.

Lens Distance Width
2.8 mm 10 feet 15 feet
3.6 mm 30 feet 30 feet
6 mm 60 feet 20 feet

*Many of our customers require a standard fixed wide angle 3.6mm lens. They are designed to be installed in a corner, provide a 90 degree field of view, and provide effective surveillance in a 30 x 30 foot area.

If you need to adjust the angle and are not sure when viewing a cash register or looking down aisles, we recommend a varifocal lens which you can adjust manually based on the angle and distance of the camera to the subject. For example, with a cash register we recommend a 4-8mm varifocal lens so you can manually adjust and capture the money, hands, and register close up. When in doubt, go with a varifocal adjustable lens.

Selections Tips for CCTV Camera Lens

3 easy steps for proper selection of security camera lens.

  • Which suit better Manual/Auto Iris or DC Lens?

Manual Iris will produce better result when surrounding illumination remains fix; Ideal for store and office place.
We recommended Auto Iris when light frequently changes.

  • What type of focal length lens is required?

Note: Smaller Focal Length number – field of view will be wider
To view maximum area of office, stores etc. go for 2.8 or 4 mm lens; this will help you to view distance and wide.
To view minimum or limited area like entrance, only cash counter etc go for 8mm; it will make narrow view and objects look closer.
Varifocal lens give the flexibility of choosing better area view
