Power over Coax Camera

In-Wall Junction Box Mounted

B/W Color

This general purpose surveillance camera utilizes a built-in NetMedia Power over Coax (PoC) Video Encoder and external
PoC Video Decoder to exchange power and video across a single coax cable, such as RG6. There is no need to run multiple
cables to the camera location! It mounts in a typical single gang junction (light switch) box and is viewed with a security
monitor or television. To view the camera on a single standard television, use the TV’s composite RCA Video Input jack.

Product Includes:

1. Camera Assembly (Camera, Camera Bracket, PoC Video Encoder, F-Connector Cable).

2. NetMedia PoC Video Decoder and 24V DC 200mA Power Transformer.

3. Mounting Screws and RCA Video Cable.

4. Two Lens Cover Inserts (Dark Lens Cover, Clear Lens Cover).

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

Installation Procedures:

1. Connect a coax cable (RG6 recommended) to the F-connectors of the camera and Video Decoder. Each
Camera/Decoder pair needs a dedicated point-to-point wiring circuit. Do not connect the Camera/Decoder coax to

video distribution equipment! Doing so could damage this product and/or the other attached devices!

2. Connect a video cable from the viewing device (monitor, Quad, DVR, modulator, etc.) to the Decoder’s RCA Video Out
Connector. Simple adapters, such as RCA to BNC, may be used where appropriate.

3. Connect the 24V DC 200mA Power Transformer from an AC outlet to the Decoder’s Power Input Connector.

4. Install Camera Assembly into the Junction Box (not included) and adjust for proper viewing.

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

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

Frequently Asked Questions

Q- Can I connect the camera coax to video distribution equipment?

A- NO! Do not connect the F-Connector coax of the camera or Decoder to other video equipment! Doing so

could damage this product and/or the other attached devices! The Decoder ouputs DC voltage on the coax

that other equipment may not be prepared to handle. Each camera and Decoder pair needs a dedicated
point-to-point circuit; nothing else can share the coax. Also, the camera itself will not work properly with RF
splitters, diplexers, and amplifiers. The RCA Video Out jack of the Decoder can connect to composite video
equipment such as monitors, TV’s, DVR’s, and modulators.

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

A- The composite video signal from the PoC Decoder 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 Decoder 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- Is there some way I can get One Wire Video

™ over coax with other cameras?

A- Yes, the NetMedia PoC Video Encoder and Decoder can be purchased as a set, NM-POCSET, for use with popular

12V DC cameras. The Encoder will accept the camera’s composite video signal and output about 150mA of
regulated 12V DC power.

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- 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.

NM-POCJBOX

Q- Will the camera work at distances beyond 100 feet?

A- Though we do not recommend or support doing so, some people find that the camera functions satisfactorily at

distances greater than 100 feet. At that range, the video quality degrades as the cable length increases but until
the power gives out over the next few hundred feet, it may still be acceptable for your application.

Q-What is the difference between Power over Coax and modulated devices?

A- Both are similar because they enable One Wire Video™ using a single coax. They differ though in their type of

video output signal. Our modulated devices, such as the RM70 (which supplies remote power for popu;ar 12VDC
cameras), output a TV channel that requires a TV tuner to view. This is handy for distributing the signal to all the
TV’s with the same coax, splitters, and amplifiers that transmit the local antenna, cable, or satellite signal. It is more
inconvenient though, for using the signal with equipment that does not have a tuner such as a security DVR or
Quad screen display. Our PoC modules and cameras output a composite video signal that is directly compatible
with such equipment. Whole house distribution can still be accomplished with PoC by modulating the output of
the DVR or Quad.
