Security Camera Mounting Tips

Security Camera Mounting Tips

security camera mounting tipsWhen investing in a security camera solution, there are many questions that can come up. One that I hear most often is, “Where should I put my cameras to get the best coverage?” Below, I will uncover some camera mounting tips that will save you time, money and headaches.

  • Entrance/Exit Areas – This is how people get in to your home or business and, more importantly, this is how they leave your home or business. Mounting a camera above an entrance/exit area that will give you a good clear visual on who is coming and going is highly recommended.
  • Areas of Importance – If you have a room or area that has valuables or is of high importance, it is highly recommended to put a camera viewing the area of importance.
  • High Traffic Areas – It is recommended to put a camera (or cameras) up in high traffic areas or areas that will have multiple people. This could include a lobby, sales floor, shipping/receiving dock, etc.
  • Parking Lot/Driveway – There is a lot that can happen in a parking lot (for a business) or a driveway (for a home). It is recommended to have cameras viewing these areas. If your budget allows, you might also consider putting up LPR (License Plate Recognition) cameras at the entrance/exit area of your parking lot to capture license plates of people who are coming onto and leaving your property. Technology is available now that will allow you to trigger an alert or set off an alarm if a license plate comes onto the property that you banned. This could be a shoplifter, ex-employee, etc.

BONUS: Megapixel IP cameras provide a higher resolution and more clarity than analog cameras. In many cases, you can use one megapixel IP camera in place of multiple analog cameras.

Mounting cameras correctly to get the right view of your home or business is critical to getting the desired footage, if something were to happen.

Security Camera Lens Calculator

Security Camera Lens Calculator

security camera lens calculatorThe lens on a security camera is one of the most important things you need to look into.  Why?  Because, the lens determines how up close or far away your view is.  A camera lens providing a zoomed in view of the entrance/exit area to a parking lot is going to be much different a camera lens viewing a wide angle shot of a sales floor.  How do you know which lens is right for you?  You will need a lens calculator.

There are many lens calculators out there, but in the past 7 years, I keep going back to the same one.  It can be found at the following link:

http://www.vihon.com/Vihon_Calculators/Vihon_Lens_Calculator/body_vihon_lens_calculator.html

Follow the steps below to make use of this easy to use lens calculator:

  1. Select the “Imager Format”.  This is the type of chipset your camera has.  Most cameras are either 1/3″ or 1/4″.
  2. Next, in the “Distance to Object” field, enter how far away the camera will be from your target area that you want to view.
  3. Next, in the “Lens Focal Length” field, enter the mm lens you are looking at.  For example, if you are looking at a 3.6mm lens, you would enter “3.6”.
  4. Next, under “Specify F.O.V. Perspective–>”, select the “Horz.” radio button.
  5. After you have done this, click “CALCULATE”.  The calculator has produced what your field of view will be, which can be seen in the “Horiz. Field-of-View” and “Vert. Field-of-View” fields.

You will also be able to see what the “Horz. FOV” is for the specified “Lens Focal Length” and “Imager Format” that you have used.  For instance, a 1/3″ chipset camera with a 3.6mm lens has a 68.47 degree field of view.

Hint:  All numbers populated in the calculator are the same unit (as far as feet, meters, yards, etc).  If you populated the “Distance to Object” in “feet”, then the horizontal and vertical field of views will be populated in “feet”, as well.
