Custom Video Security Cameras Alerts

You can customize recording settings of the surveillance system based on security events, video motion detection or schedules. Choose the exact events you want to view and when they occur, we'll let you know.

For example, you may want to see exactly when your child arrives to your Los Angeles or Orange County home from school, when a senior loved one takes their medication or when your small business opens in the morning, when you get a delivery. The possibilities are endless, and the choices are all yours.  Our professional security camera installers will set specific alerts for your particular situation, call us now for a free consultation or if you have any questions.

We consider many factors when choosing and installing a surveillance system for your home or business amongst those are:

Depth of field of a security camera system lens is the area along the line of sight in which objects are in reasonable focus. Depth of field

will increase with any of the following conditions:

• In high light situations where smaller apertures are used (higher f stop numbers, see fl 6 below)

• Wide angle lenses (shorter focal lengths)

• Focusing on objects at greater distances from the lens

The following. security camera chart shows the area in focus at different aperture settings (f stops). The lens in this case is

focused at a constant 15 feet.

When combining a larger formatted security camera lens (ie. 1/2") with a smaller formatted camera (ie. 1/3") the

picture produced will be more telephoto relative to the picture produced by the same lens with a

matching formatted camera. Use the following formulas to obtain an estimate of apparent focal


1" Lens with 2/3" Security Camera Focal Length .70

1" Lens with 1/2"  Security Camera Focal Length .50

1" Lens with 1/3" Camera Focal Length .34

2/3" Lens with 1/2" Camera Focal Length .73

2/3" Lens with 1/3" Camera Focal Length .55

1/2" Lens with 1/3" Camera

• /

Focal Length .75

Example : A 1/2" 4.5mm lens used on a 1/3" camera will appear to be a 6mm lens on a 1/2" camera

[4.5mm .75 = 6mm apparent focal length]

Note : Because focal length and field of view (f.o.v.) share an inverse relationship you must

multiply by the above factors to get the angular field of view of a lens. For example a 25min 1" lens

has a f.o.v. of about 29 ; However that same lens on a 1/3" camera would have an angular f.o.v. of

10 (29 x .34).
