Security Video Camera

NM-VIDVCAM

Varifocal Day/Night Color

The NetMedia VIDVCAM Varifocal Day/Night color camera manually zooms from 3.5mm to 8.0mm in focal length to meet a variety
of surveillance requirements. It mounts to a typical round 4 inch junction box and is viewed with a security monitor. Other junction
boxes from your local hardware store may also be used after replacing the round base with another that has a 1/2 inch diameter
hole for the elbow bracket. To view the camera on a single standard television, use the TV’s composite RCA Video Input jack.

DO NOT CUT OR SPLICE THE CAMERA’S CABLES. MODIFYING THE UNIT IN ANY WAY WILL VOID THE WARRANTY.

Installation Procedures:

1. Ensure that the camera is grounded with the ground strap as shown in the FCC Information.

2. Connect a grounded video cable from the viewing device (monitor, Quad, DVR, modulator, etc.) to the camera’s
Video Connector. Adapters, such as BNC to F or RCA, may be used where appropriate.

3. Connect the 12V DC 300mA Power Transformer from an AC outlet to the camera’s Power Input Connector.

4. Mount the base to the junction box (not included) and direct the camera assembly towards the intended viewing
area. Remove the Lens Casing and loosen the zoom and focus set screws. Adjust the zoom and focus of the Varifo­cal Lens for proper viewing. When satisfied, secure all adjustment points.

FCC Information (U.S.A.):

Important: This product, when installed as specified below,
meets FCC requirements. Modifications not expressly
approved by NetMedia may void your authority, granted by
the FCC, to use the product. Failure to follow all installation
instructions could void your FCC authorization to use the
product in the USA.

Security Cameras:
FCC compliance requires fastening the included grounding
strap and ring from the camera’s BNC connector to the
camera’s base as shown in Figure 4. The connecting cable’s
shielding must be grounded. If the cable is not grounded, the
camera base must be mounted to a grounded metal electrical
junction box.

Frequently Asked Questions

Q- Why do the light areas of the picture look washed out?

A- The camera’s automatic iris must decide how much to open for shadow areas or close for light areas. When a

picture has both light and shadow, the camera adjusts the iris based on the percentage of each area in the image.
If it decides to open more for the shadow portions then the light areas will be overexposed. In addition, cameras
that are designed for low light or infrared sensitivity typically favor the shadow areas and look more washed out
under bright conditions. Try adjusting the image field so that more light areas are visible and see if the iris closes
to improve the picture. It is normal though, that as the lighting conditions change throughout the day, so will the
camera iris and the picture’s dark or light areas.

Q- Why are the shadow areas too dark to see much detail?

A- This is like the washed out question above except opposite. In this case, the camera’s automatic iris is opening

more for the light areas at the expense of the shadow areas. Try adjusting the image field so that more shadow
areas are visible and see if the iris opens to improve the picture. Keep in mind though, that the camera still does
need some kind of light in order to see. If necessary, add some lighting to the dark area to improve visibility.

Q- How can I see the camera on my TV without using an expensive security monitor?

A- The composite video signal from the camera can be plugged directly into one television’s RCA Video Input jack

and viewed when that TV is switched to the proper input. Another option is to feed the camera signal into a
modulator. A modulator, such as NetMedia’s MM70, changes the video to a UHF or Cable channel and allows the
signal to be distributed to all your TV’s along with the existing antenna/cable/satellite service.

Q- How can I increase the length of the power cord?

A- The camera has a minimum power requirement of 12V DC 150mA (it ships with a 12V DC 300mA transformer). You

may use another power supply and cable but the connector needs to be just like the power jack of the included
transformer, 5.5mm outer dia., 2.1mm inner dia., center positive. Do not cut the cables coming out of the camera

or you will void the warranty. Do not reverse the polarity on the power jack or you will damage the camera
and void the warranty. The power supply, along with the cable type and length, will affect the voltage that is

available to the camera. There must be at least 12V DC under load at the camera in order for it to function properly.

Q- How can I use this camera if there is only one coax running to its location?

A- This camera was designed for use with separate power and video cables. NetMedia does however, offer One Wire

Video™ solutions for various installation applications. In this case, you could use the Power Over Coax
(NM-POCSET) modules to supply power through the video coax to this camera. NetMedia’s CAModulator products
are cameras with modulators already built into them. They also require only one coax for both power and video.
Modulated video requires a tuner for viewing so monitors, quad displays, and DVR’s cannot directly accept that
type of signal.

Q- What do the switches inside the “D” Day/Night camera adjust?

A- The Day/Night camera comes with a switch connected inside to adjust some of its performance characteristics.

The switch functions are listed below (Figure 5). The default settings (All OFF) are usually best but adjusting these
may be helpful under certain conditions. The AGC switch will force the camera to remain in color mode instead of
changing into black and white mode when the light level drops below its normal crossover threshold.
