A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Warning: Changes or modifications made to this equipment, not expressly approved by EverFocus or
parties authorized by EverFocus could void the user's authority to operate the equipment.

Precautions
1. Do not install the camera near electric or magnetic fields.
Install the camera away from TV/radio transmitters, magnets, electric motors, transformers and
audio speakers since the electromagnetic fields generated from these devices may distort the video
image or otherwise interfere with camera operation.
2. Never disassemble the camera beyond the recommendations in this manual nor introduce
materials other than those recommended herein.
Improper disassembly or introduction of corrosive materials may result in equipment failure or other
damage.
3. Try to avoid facing the camera toward the sun.
In some circumstances, direct sunlight may cause permanent damage to the sensor and/or internal
circuits, as well as creating unbalanced illumination beyond the capability of the camera to
compensate.
4. Keep the power cord away from water and other liquids and never touch the power cord with wet
hands.
Touching a wet power cord with your hands or touching the power cord with wet hands may result
in electric shock.
5. Never install the camera in areas exposed to oil, gas or solvents.
Oil, gas or solvents may result in equipment failure, electric shock or, in extreme cases, fire.
6. Cleaning
For cameras with interchangeable lenses, do not touch the surface of the sensor directly with the
hands. Use lens tissue or a cotton tipped applicator and ethanol to clean the sensor and the camera
lens. Use a damp soft cloth to remove any dirt from the camera body. Please do not use complex
solvents, corrosive or abrasive agents for cleaning of any part of the camera.
7. Do not operate the camera beyond the specified temperature, humidity or power source ratings.
Use the outdoor camera at temperatures within -40°C ~ +50°C ≦95% / -40°F ~ +122°F ≦95% and
the indoor camera at temperatures within -5°C ~ +50°C ≦85% / 23°F ~ +122°F ≦85%; this device
is not rated as submersible. The input power source is 24 VAC~ / PoE. Be sure to connect the proper
+ / - polarity and voltage, as incorrect polarity or too high a voltage will likely cause the camera to fail,
and such damage is not covered by the warranty. The use of properly fused or Class 2 power limited
type supplies is highly recommended.
8. Mounting
Use care in selecting a solid mounting surface which will support the weight of the camera plus any
wind, snow, ice or other loading, and securely attach the camera to the mounting surface using
screws and anchors which will properly support the camera. If necessary (e.g. when mounting to
drop ceilings) use a safety wire to provide additional support for the camera.

1. Introduction
The EPN series is a high-performance IP speed dome supporting up to 22x optical-zoom and dual streams
from H.264 and MJPEG. The series comes in two types: outdoor (EPN4122 / 4220 / 4220p), indoor
(EPN4122i / 4220i / 4220pi). Equipped with a weather-proof (IP66) and vandal-proof (IK10) housing, the
outdoor models meet a wide variety of needs for outdoor surveillance.
EverFocus IP speed dome provides Auto Tracking function to detect movement in the camera’s field of
view; and variable pan/tilt speeds ranging from 360°per second to 0.01°per second with 0.1°position
accuracy for fast and accurate monitoring. A maximum of 192 preset points can be configured for precise
location of target areas. Features like 360°endless rotation, 16 tour sequences, 4 patterns are all provided.
The IP speed dome also features Wide Dynamic Range (WDR) function, which can provide clear images
even under back light circumstances where intensity of illumination can vary excessively. The DNR (Digital
Noise Reduction) function is designed for reducing the noises in the images, allowing the camera to better
distinguish between real motion and image noise, and thus results in a possibility to store more video
evidence on the connected storage devices.
A built-in micro SDHC card slot is also provided. You can power the camera by connecting the camera to a
24 VAC power supply or a PoE switch. Since the EPN series IP speed dome conforms to ONVIF / PSIA for
compatibility with other network video devices, it interoperates with a wide variety of hardware and
software systems. You can also use EverFocus Mobile Applications to remotely view the live views of the
cameras through your handheld devices; or use EverFocus CMS to remotely manage multiple IP devices
connected on the network.

3.5.2 Important Note for Installation
Before installing, insert a micro SD card into the main body and replace the 3 desiccant bags inside
the top housing. The desiccant bag loses its effectiveness after you open the camera. To keep the
camera’s interior dry, it is highly recommended to replace the desiccant bags every time when you
open the camera.
3.5.2.1 Replacing the Desiccant Bags
1. On the Top Housing, slightly press the black plastic socket backward and lift up the base
board.
2. Remove the desiccant bags from the top housing.
3. Stick the supplied 3 new desiccant bags inside the top housing.
Note: Ensure Not to place the desiccant bags under the position of the fan.
4. Insert the base board into the black plastic socket. The base board should click firmly into
position. Make sure the pin connector on the base board is lined up with the pin connector
on the main body when you press the two together.

3.5.2.4 Optionally Setting Up the DIP Switch
To allow the control device, such as a keyboard, to recognize and then control multiple cameras,
you need to set up the ID address for the cameras using the DIP switch on the Camera Main Body.
You can also set up the Protocol and Baud Rate for the cameras.
Note: Please ensure to turn off the power when setting up the DIP Switch. The new values will
only take effect after restarting the camera.

Camera Main Body
ID Address
The ID address of the camera should be set to correspond properly with the control device, such
as a keyboard. The eight switches on the right correspond with the binary code of the ID address,
allowing up to 256 ID addresses (0 ~ 255) to be set up. Please refer to the sticker on the camera
main body or the following diagram for setting up the ID address. The default ID address is 1.

3.5.3 Wall-Mount Installation
1. Replace the desiccant bags inside the top housing. See 3.5.2.1 Replacing the Desiccant Bags.
2. Drill 4 screw-depth holes for mounting the bracket base plate and then drill a through-wall hole
for inserting the camera cables. You can optionally drill a second through-wall hole to separate
cable feeding (see Step 4).
3. Attach the waterproof silicon pad to the bracket base plate for waterproofing.
4. Feed the camera’s cables through the conduit in the wall mount bracket.
