3.Remote Control
Remote control instructions: remote control is divided into two types: infrared remote control and wireless remote control.
Please read the following contents according to the actual remote-control type.
3.1 Code Matching for Wireless Remote Control
One to One Code Matching:
Press the "set" button and "[CAMERA NUMBER]" keys combined for 3 seconds, LED indicator
starts flashing. When the camera receives the signal the power on LED indicator will go off if
the code matching was successful. The camera can then be controlled by this remote control after
one to one code pairing. Otherwise please clear the code matching of this remote control or
use another remote control to pair with the camera again. If one to one code matching failed, the
red LED light flashes for 20 seconds and then goes off, the camera will stop code match and turn
on sleep mode; Press any key to wake up the camera and restart code matching procedure.
Note: After code matching is successful, please select the camera address to control it.
Clearing Code:
Press the "set" button and "[CAMERA NUMBER]" keys combined for 3 seconds, the LED indicator
starts flashing. The camera will power off and on, the LED indicator will go off if code clearing successfully.
Sleep Mode and Wake Up:
Press any key to wake up the camera from sleep mode.

3.2 Keys Introduction for IR Remote Control
1) In this manual, “press the key” means a click rather than a long-press, and a special note will be given if a long-press
for more than one second is required.
2) When a key-combination is required, do it in sequence. For example, “【*】+【#】+【F1】” means press“【*】”first
and then press“【#】” and last press“【F1】”.
1. Standby Key
The camera enters standby mode if long pressed for 3s on standby key;
Long press 3s again on the standby key, the camera will self-check again and return to HOME position (If preset 0
position is set, the camera will return to preset 0 position).
2. Camera Selection
Select the camera address to control.
3. Focus Control
Auto: auto focus mode
Manual: manual focus mode
Focus + (near):Press【FOCUS +】key (Valid
only in manual focus mode)
Focus -(far):Press【FOCUS -】key (Valid only
in manual focus mode)
Press and hold the keys, the action of focus will
keep continue and stop as soon as the key is
released.
4. Zoom Control
ZOOM +: press【ZOOM +】key to zoom in
ZOOM -: press 【ZOOM -】key to zoom out
Press and hold the keys, the action of focus will
keep continue and stop as soon as the key is
released.
5. Set and Clear Presets
