General
**900MHz wireless product general Q&A may correlates with 2.4GHz wireless Q&A, please referes to SecurityMan 2.4GHz wireless camera Q&A for general troubleshooting including possible causes of interference, how to connect to TV/VCR, transmission distance range, etc.
**The 900MHz wireless cameras can support up 2 cameras maximum.
 CUcam1
Q1: Can i add more than one camera to my receiver or use more than one CUcam1 kit in the same location?A1: No, the receiver for CUcam1 can only support one camera (906MHz) and two CUcam1 kit cannot be used in the same location.  However, more than one receiver can be use in different rooms in the same location, the camera will pick up the same camera image.
Q2: I lost my antenna for the receiver, will it still work?A2: Yes, it will still work.  However, it will affect the performance and shorten the distance between the receiver and camera.  Contact us or you local eletronic stores for an antenna for better picture quality.
Q3: What should I do with the three white switches on the back side of the receiver?A3: This is model dependent, if you have a receiver with the three switches, switch all three white swtiches to the “UP” position.
Q4: Thre is no picture from my camera?A4: Check all connections to the camera and the receiver.  Make sure the camera and the receiver are both ON and that the camera is in range of the receiver.
Q5: The image from the camera is choppy and/or keeps cutting out?A5: The wireless receiver may be out of range of the camera.
Q6: I can not hear any sound out from my television?A6: Check the connections between the receiver and the television, specifically the red and white connector are plugged in correctly into the audio port, please refer to your television manual for audio color codes.  Check the volume setting on the television to be on.  There may  not be a sound source close by the wireless camera where the microphone is located, test audio by making sound/noise near the camera. 
Q7: I already have a surveillance DVR (digital video recorder); can I connect CUcam1 to it for recording and playback?A7:  Yes, depending on the DVR’s connector interface, an “RCA (female) to BNC (male)” converter may be require to adapted from the CUcam1 receiver to the DVR interface
Q8: Can I connect CUcam1 to my TV DVR (digital video recorder)?A8: No, most TV DVR does not have video input port to connect our receiver into for recording.  Although they are both called “DVR”, but they have different purposes and functionalities.
Q9: Why does the camera displays black and white instead of color?A9: When the light sensor detects the area to have low lux level or low light level, the IR (Infra Red) LED will automatically comes on and therefore turning the camera image to black and white, this is normal when the IR becomes active.
Q10: Does CUcam1 interfere with other 2.4GHz/2.5GHz wireless cameras or Wi-Fi network routers?A10: No, CUcam1 uses 900MHz avoiding interference with other 2.4GHz and 2.5GHz wireless cameras.  Since Wi-Fi wireless routers or AP uses 2.4GHz band, it will not conflict with 900MHz CUcam1 system.
Q11: Can i use CUcam1 in other countries beside the United States?A11: It depends.  Most Europe and Asia countries uses 900MHz & 1800MHz GSM cell phones which can conflict with CUcam1 900MHz band.   
CUcam2 (discontinued)
Q1: Can I connect a 3rd 900Mhz SM-302TX camera to the receiver?
A1: No. The SM-302RX receiver can only support a total of 2 900Mhz channel cameras.
Q2: I have both SM-302TX cameras connected at once, but only one can display an image, what is wrong?
A2: It is possible that each SM-302TX camera was set to the same frequency (ie. Ch.1 906Mhz). Make certain that one of the outdoor cameras is set to Ch.2 924Mhz. The channel 1, 2 switches are located on the rounded thicker area underneath the rubber flap, near the camera’s own power jack.
Q3: I have the receiver connected to a DVR recorder, how comes it records one camera at a time?
A3: The receiver SM-302RX receives two cameras images one at a time and outputs/displays one at a time every 5 seconds or so in rotation. It is recommended to buy one more receiver, and set the first receiver for channel #1 and the 2nd receiver for channel #2. Then, connecting two receivers to a DVR recorder’s video inputs for recording both cameras at the same time and able to monitor or playback both cameras at the same time.
ClearCam II (discontinued)
Q1: Can I adjust the focus on the ClearCam II camera?
A1: Yes, the focus can be adjusted; please remove the front lens cover by turning it counter-clock-wise (as illustrated in Q2, Step 4 below), remove the circular foam surrounding the lens off, hold or grip onto the camera lens and then turn to adjust the focus. Note: if more room is needed in order to better grip the lens, please remove the two screws that holds the infrared LEDs and circuit board and carefully pull out the board, as illustrated in Q2, Step 5 below.
Q2: My ClearCam II camera image looks great during the daytime but becomes dark or has a bright hallo in the center and cannot make out an image during the nighttime?
A1: Try adjusting the brightness, sharp, hue, and contrast of the TV output for better image contrast.
A2: Adjusting the transistor brightness/contrast knob as follow:
Tools Required:
• box cutter or pen knife.
• size 1/8” philips or flat head screwdriver
Optional Item:
• black colored electrical tape
Step 1
Disconnect the 12V power adapter plug from the SM-8123T camera power jack.Step 1
Step 2
Turn counter clock wise to loosen the antenna & position it down away from the visor.Step 2
Step 3
Next, slide the sunshade back about 1 ½” towards the rear of the camera.Step 3
Step 4
Unscrew by turning counter clock wise to remove the lens cover from the camera.Step 4
Step 5
Use a screwdriver to remove two small screws located on the Infra-Red circular board, one located on the left side below the IR sensor & the other on the board’s upper right side.Step 5
Step 6
Gently hold & move the IR circular board slightly out, enough to see the inner square video board with lens. Do not overstretch the IR circular board to prevent from disconnecting its three wires. The IR circular board needs to be physically held or using electrical tape attached to the camera’s top area. The adjustment resistor is located just above the four solder joints on the inner square video board.Next, check to see if there are any white pastery covering over the adjustment resister, if no pastery proceed to step 7. If there are white pastery; use a blade tip to gently make an ‘X’ or ‘+’ shaped cut over the white glue located on the video board’s middle left side to reveal the adjustment resistor. Then make a small cut right above the adjustment resistor. This will allow the screwdriver to be placed & fit over the cut. Position the blade carefully to avoid cutting a wire or scratching the inner video board surface.Step 6
Step 7
It’s not necessary to remove any white glue, as it provides component protection from metal objects, & facilitates the screwdriver rotation process.If the antenna was removed, then screw it back into the camera. Reconnect the 12V power adapter jack into the camera. Hold & point the camera across a well lighted room. Use the screwdriver to slowly turn the resistor, about a millimeter length at a time, while adjusting the image. Turn the resistor clockwise to brighten image, colors or counterclockwise to darken image, colors.Step 7
Step 8
If the IR circular board is attached to the camera’s top area with electrical tape, then remove it. Place the IR board over the inner video board. Next, hold the IR board & camera body together & give the camera a quick day & night test.After adjusting the image to desired levels, disconnect the 12V power adapter jack from camera. Carefully tuck the IR circular board’s three wires into the camera, align the holes, & secure it with the small screws.Step 8
Step 9
Screw on the front portion of the camera (lens cover) tightly & slide the sunshade towards the front. Finally, reposition the antenna upward.Step 9
Step 10
Reconnect the 12V power adapter jack to the SM-8123T camera. It is ready to use.Step 10

PalmWatchIII (discontinued)
Q1: For the SM-8209T indoor camera, can I use the AA batteries & the 8V power adapter both at once?
A1: No. If the 8V power adapter is connected & is used to turn on the camera, then remove the AA batteries from the battery compartment.
