B/W Color

The NetMedia MODJBOX (SC01, SC02, SC03) self contained camera and modulator converts its video signal to a selected
television channel. It is powered over the same coax cable that returns the video broadcast signal for One Wire Video™
installation. It mounts in a typical single gang junction (light switch) box and is viewed with a television tuner. Equipment
that does not have a tuner, such as a security monitor, Quad display, or DVR, will require a demodulator (any TV tuner device
with a composite video output such as a VCR) to convert the video for its use.

DO NOT CUT OR SPLICE THE CAMERA’S CABLES. MODIFYING THE UNIT IN ANY WAY WILL VOID THE WARRANTY. DAMAGE FROM
EXPOSURE TO MOISTURE, STATIC DISCHARGE, OR OTHER HARMFUL ENVIRONMENTAL FACTORS IS NOT COVERED BY THE WARRANTY.

Installation Procedures:

1. Set the channel with the switches as shown in Figure 1. Choose an unused channel that matches the tuning mode of the
televisions. With antenna tuning, choose a UHF channel from 14-69. With cable tuning, choose a CABLE channel from 70-94
or 100-125. There must be at least one blank channel on either side of the modulated channel to separate it from any other
broadcast, cable, or modulated source. When combining with cable service, be aware that digital data typically interferes
with channels 80-117, even when not subscribed to digital services. Channels 120-125 often work without any filtering.

2. Ensure that the camera is grounded with the ground strap as shown in the FCC Information. Connect a coax cable from
the camera’s F connector to the “MOD” side of the Power Injector. Connect the “TV” side of the Power Injector to the
grounded coax from a television or distribution system. Connect the 12V DC 300mA power supply to an AC outlet and
the Power Injector. The camera picture is now available on the programmed TV channel.

3. Install Camera Assembly into junction box (not included) and adjust for proper viewing.

4. Snap the dark or clear Lens Cover into the Cover Plate (not included) by pressing all four corners in simultaneously.

5. Attach the Cover Plate to the Junction Box. Silicon or similar sealant may be used as needed.

Frequently Asked Questions

Q- When using the Dark Lens Cover, why does the picture look too bright, dark, or strange?

A- The dark lens covers make the camera less obtrusive but they may not work well under some conditions. The cover that ships with the

color camera is similar to tinted sunglasses; it needs bright light in order to provide a good picture. The cover that ships with the B&W
camera only passes infrared (IR) wavelengths; it needs incandescent, IR, or sun light in order to show anything. This can lead to
unexpected results. The image will be dark under bright flourescent lights but bright when viewing dark grass or trees. Vegetation and
other items can appear quite strange when seen through the IR spectrum. Use the clear lens cover when the dark one is not suitable.

Q- When using the Clear Lens Cover, how can I make the camera less visible?

A- Try painting the inside of the lens cover black while leaving a small clear area for the camera to see through.

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 do I find out if the camera is working when I can’t see it on any televisions?

A- Start with a basic setup: connect camera to coax, coax to power injector, power injector to TV with no amplifiers, splitters, filters, cable

boxes or other devices involved. Set the camera to a channel that matches the TV mode: 14-69 for Antenna tuning; 70-94 or 100-125 for
Cable tuning. If the TV can tune channel 70 or above, then it is probably in Cable tuning mode. Set a simple channel like 20 or 120 and
look for it on the TV. Check power, power injector direction, connections, cables, TV tuning mode, and camera switches to correct any
problems. You must see the camera picture to confirm that it works in this basic setup before moving on to more complex setups.

Q- Why does the camera or cable service picture go bad when the two are combined together?

A- The signals should be combined at the beginning of the distribution system before the cable service goes through any splitters. Make

sure you are not using any diplexers to split or combine. Once done, there is either interference or the signals are not balanced. Most
interference comes from invisible digital data that is on the line even when not subscribed to it. Set the camera for a clear channel, try
120, or use a filter to remove the digital/analog interference. When there is no interference you can balance the signals by amplifying
the weaker, snowy one before the two are combined. 10 to 20dBmV is usually enough, too much will degrade the other signal.

Q- Can the camera be combined with digital cable service?

A- Yes. The difficulty is in finding a clear channel for the camera. The digital data usually takes up the analog channel range of 80-117 so

channel 120 is a good place to start. Analog 120 on the TV will not conflict with digital 120 on the cable box. If you cannot find a clear
channel then you will have to use a notch or low pass filter on the cable service before you combine it with the camera. Make sure the
filter does not remove any subscribed digital services including an Internet connection. If only one location is using the digital services
and it does not need to see the camera, you can split its run off before the main line is filtered and combined with the camera. This
prevents the filter from disrupting the digital data while enabling the camera to appear on the rest of the TV’s.

Q- How can I see the camera when the TV uses a cable box?

A- There are a few ways but they all involve bypassing the cable box and using the TV tuner to see the camera. Combine the camera with

the cable service and check its picture by connecting the coax directly to the TV. Any splitters, filters, or amplifiers you use for
combining are separate from the ones used to bypass the cable box. After verifying the camera picture, split the coax two ways with
one side going to the cable box. If you use the cable box S-Video or composite output then the other side of the splitter goes directly
to the TV. If you use the cable box coax output and there is only one coax input on the TV, then you must use a ch. 3/4 filter (included
with NM-ACB3) and recombine the coaxes as shown in Figure 5. In any case, view the cable box through the appropriate TV
connection, Video 1, ANT 2, channel 3/4, then change the TV (not the cable box) to the camera channel.
