DigiairWatch/2 & DigiLCDDVR2/4 Q & A
Q1: Why does “Warning SD card ejected unsafely” pop up whenever I remove the SD card from the receiver? 

A1: This is just a visual indication that the SD card was ejected before it was unmounted.  Please use the “SD Unmount” option under the Playback/SD Card settings prior to ejecting/removing the SD card from the DVR.


Q2: Why there is no audio?


A2: Please try adjusting the volume on the monitor that the DigiairWatch is plugged into.  Next adjusting the volume on the receiver by pressing the “Up” arrow key. Check the connections between the receiver and the TV, specifically the red and/or white connector(s) are plugged in correctly.  Check the volume settings on the TV. Also, remember that the range of the microphone is not the same as the range of the camera.  The camera will detect anything in front of it that it sufficiently lit, however a microphone will only pick-up sound within a few feet (unless the sound is very loud).


Q3: Can the receiver record 4 cameras at the same time and how can I accomplish it?


A3: Yes, the receiver treats every channel separately and each channel has its own recording table.  In Quad Mode, make sure “1” is highlighted in blue, and press “Record” button, then press “Camera” button to switch to Channel 2, and “2” is not highlighted in blue, and press “Record” button.  Repeat the same for Channel 3 and Channel 4.


Q4: Why the image becomes black and white at night time?


A4: Because the night vision on the camera is triggered automatically when the light sensor detects that there is not enough candle light.  Once the infrared kicked in the images will become black and white, this is normal.


Q5: There is no image on the LCD screen or on the TV screen?


A5: Make sure the camera is getting power from the 5VDC power adapter.  Ensure that the camera is paired with the receiver by pairing instructions (reference user manual).  Check that the channel you are displaying is the one paired with the camera. If all above fails, try moving the camera closer to the receiver, and be sure there are no obstacles (such as walls or metal sheets) in between the camera and the receiver blocking the signal.


Q6: The image from the camera(s) is choppy and/or keeps cutting out?


A6: The wireless receiver may be out of range of the camera(s). Try setting the camera(s) and/or receiver to different locations and elevates both the cameras and receivers as high up as possible.


Q7: What’s the recommended distance when paring new cameras?


A7: For best results, pairing should be done within 20 feet.  After successfully being paired to the receiver you can then unplug and mount the camera in the desired location.


Q8: Why is it not recording?


A8: First please adjust the correct recording setting.  Next make sure SD card is inserted and is NOT locked by adjusting the tab on the side of the SD card.


Q9: What do I do when my SD card becomes full?


A9: There is no need to worry about this issue because the system has an automatic “Overwrite” feature that prevents the SD card from ever becoming full.


Q10: Can I add more than one camera to my receiver?


A10: Yes, you can add a total of 4 cameras to the receiver.


Q11: What does ’clear line of sight’ mean?


A11: “Clear line of sight’ means that there are no obstructions which may interfere with the transmission of the wireless signal.  Obstructions include items such as studs, walls and certain electronic devices.


Q12: Can I use two receivers (SM-371DR and/or SM-804DR) to monitor one camera (SM-816DT) at the same time in two different rooms?


A12: No, one camera cannot be paired to multiple receivers (SM-371DR, SM-804DR).  However, one receiver can paired up to 4 cameras.


Q13: I kept on getting “SD Card Error” message when i inserted the SD card into the SD card slot, why?


A13: Please make sure that the SD card is formatted using FAT32 file system format and not NTFS file format.  Double check to make sure that the SD card is inserted correctly (the SD pins are facing away from you), and the lock/unlock switch on the SD card is set to unlock position.


Q14: I’ve ordered the DigiairWatch2, DigiLCDDVR2, or DigiLDDVR4 systems, can I purchase more receivers/monitors to set one receiver for one camera to monitor both audio and video from each of the camera?


A14: Yes, additional receivers/monitors can be purchased for the purpose of monitoring one camera per receiver or to feed into other recorders.


Q15: Is there a volume control on the DigiairWatch, DigiairWatch2, DigiLCDDVR2, and DigiLCDDVR4 systems?


A15:  Yes, press the “Up” or “Down” buttons to control the increase or decrease of your receiver’s volume in both live view and playback respectively.


Q16:  Why is it that when I setup my date/time on the SM-804DR/SM-371DR and then restarting the device(s), the date/time always reset to November 01, 2011?


A16: Please be sure to leave the power adapter plugged into the SM-804DR/SM-371DR for several hours before attempting to power off the device(s).  Doing so will allow the date/time to sustain when the receivers are turned off.


Q17:  How many sets of DigiairWatch systems and DigiLCDDVR2 systems can I use in one location?


A17:  Up to 7 sets of varieties of DigiairWatch and DigiLCDDVR2 systems can be installed and use in one location.


Q18:  I accidentally changed the TV Standard from NTSC to PAL, and now the image on the monitor is rolling, how can I change it back to NTSC?


A18: please do the following:

a)  Turn off your SM-804DR or SM-371DR and then turn it back on, wait 30 seconds.

b)  Press “Menu” button once

c)  Press “OK” button once

d)  Press DOWN ARROW button three times

e)  Press “OK” button once

f)  Press the UP ARROW button once

g)  Press “OK” button once, done!


Q19: Do you have a larger screen for the SM-371DR 7″ monitor?


A19: No. The reason for this is that the SM-371DR is equipped with an AV output port (located above the power port) that will allow you to connect the current 7” monitor to a larger monitor of your choice (10”, 32”, 47” etc).


Q20: Why does my wireless camera occasionally get disconnected?


A20: There are several factors which may cause occasional wireless connectivity issues.  Here are some of the most common factors:

•Your connectivity is being affected by environmental surroundings such as cell phone towers, a strong radio frequency interference from nearby RF emitting devices, or even concrete, brick and metal.
•You are too far away from the wireless receiver.

Due to FHSS technology (Frequency Hopping Spread Spectrum) the signals emitted from a wireless router may occasionally collide with a wireless camera and cause the camera image to freeze, or appear choppy.


Q21: WIll the DigiLCDDVR/DigiAirWatch systems interfere with my cell phone, iPad, access point and WiFi router?


A21: The DigiLCDDVR and DigiAirWatch series uses 15 differenet channel frequencies that automatically jumps from one frequency to the next every 5 seconds.  Meaning when there are channel frequency conflict, our system will automatically modulate to antoher channel frequency to avoid the interference.  Conflicts may occur when the DigiLCDDVR/DigiAirWatch systems are place dtoo clos to other devices (such as a cell phone, iPad, access point, WiFi router…).
