Usage

Indoor/Outdoor · Do not run inside

walls or underground

Indoor/Outdoor · In-wall or along wall

Other Notes:

· If a cable run exceeds 200ft, we recommend using the RG-59 cables shown in the right two

columns of this table which are available through www.Q-SeeStore.com.

· Longer cable runs will require a stronger power supply or for the power supply to be closer to

the camera.

To maintain video quality:

· Video quality is always enhanced by using shielded cables.

· To prevent video signal loss, run one continuous cable between the camera and DVR for best

results. If more length is required, use the minimum number of inter-connection points possible.

PRECAUTIONS: FREQUENTLY ASKED QUESTIONS:

CAUTION! Risk of electrical shock.

To prevent

electric shock, do not remove screws or cover.

Handle camera with care.

Do not hit, shake,

puncture or drop the camera as this could cause

damage and prevent proper operation.

Do not attempt to disassemble camera.

There are

no user serviceable parts inside. Service should be

performed by a qualiﬁed Q-See technician only.

Avoid excessive moisture within camera or

adapters.

Do not use strong or abrasive detergents

when cleaning camera body. Clean with dry cloth or

mild detergent, wiping gently.

Do not use camera beyond prescribed voltage range.

Only use included power supply. Ensure power input

source conforms to local voltage. Voltage outside of

range could cause damage or abnormal performance.

Avoid strong light.

Do not aim camera at sun or

aim strong light directly into the lens as it will degrade

image quality and could cause damage. Camera should

ideally be placed out of direct sunlight for improved

performance.

Protect from elements.

Indoor/outdoor cameras are

weatherproof but direct exposure to excessive rain, sun

or marine environmental conditions will degrade their

performance and shorten the life of the product.

Indoor-only cameras should NEVER be used outdoors.

Even if sheltered from direct exposure, they will still be

damaged by dust and moisture in the air.

Below are some frequently asked questions regarding cameras. Additional information, plus live chat (during regular

business hours) can be found at www.Q-See.com/Support

Lines in the video images. Check the cable. If you connect a camera that is working to the cable of the

camera that has the lines and it too shows lines, replace the cable. If you are in an area with a lot of electrical

interference, switch to a shielded cable such as RG-59.

No video from camera. Check all connections and make sure that camera is connected to proper power supply.

Check to see that the camera is receiving power by cupping hand over lens. You should see a faint red glow from

the LEDs. Check camera on known functioning cable to determine if issue lies with camera or cable.

Cable extended to more than 60 feet and no video or video only during the day. The camera power supply/

power splitter combination is only designed to power cameras up to 60 feet. Any cameras beyond that distance

will need their own power supply which is available at www.Q-SeeStore.com

Dark video image. Some cameras feature an infrared cut ﬁlter to improve daytime video images. This can

sometimes become stuck. Place a hand over the lens for 10 seconds to trigger night vision mode. You may hear a

soft click as the ﬁlter resets.

Upside down video image. Change the orientation or position of your camera to correct. Or, use the video ﬂip

option in your DVR’s Camera Settings menu.

Camera looking through window has video image during day, but not at night. The LEDs on the camera

act as a ﬂashlight and, at night, this light is being reﬂected by the window back at the camera. You will need to

reposition the camera outside the window.

Camera video is very dark during one time of day, but lighter during others. The camera may be positioned

so that the sun shines directly into it. This will backlight the subjects in the camera’s ﬁeld of view and cause them

to appear dark and washed out. Reposition the camera to avoid this, keeping in mind that the sun will change

positions over the course of a year as well as during the day.

Camera on metal building has excessive static. The camera will need to be seperated from the metal building

by using a rubber gasket.

WARNING! Always check state and local laws before

installing cameras and cables. (2011 NEC 820.44)
