2.4GHz wireless camera Q&A
General/MiniAirWatch/NiteCam2
General
Q1: The wireless camera system is connected to my TV input, but
I cannot see the camera picture?
A1: Please locate the remote control of your TV and look for the
input/VCR button. Press the input/VCR button once if the wireless
camera receiver is plugged into input 1 and press twice if the
wireless camera system is plugged into input 2 and so on. On some
TV sets, the input can be found by first channel to channel 2,
then down a channel once or twice to get to the correct input
in which the wireless camera system is plugged to. Please reference
the TV set user's manual to get further instruction on the input
selection.
Q2: Can I connect a wireless camera system to a VCR or
DVR to record?
A2: Yes, a wireless camera system can be connected to the input
on the VCR/DVR to record. First, note what channel/input the TV
is set on when playing video VHS tape from the VCR or when playing
recorded video files from the DVR and set the TV to that channel/input.
Next, know which input on the VCR or DVR the wireless camera system
is plugged into, ie. Input 1, Input 2, etc. Then, reference the
VCR or DVR user's manual to find what channel the VCR or DVR has
to be on to display the input, in this scenario, the input number
in which the wireless camera system is connected to. In general,
the input on the VCR or DVR can be found by channel to channel
2, then down channel once or twice. In the process of finding
the right input, look for the camera picture to show on the TV
output display. If it displays, then the VCR or DVR is ready to
record.
Q3: Why is there a horizontal line going through the display
output of my TV?
A3: Adjust the antenna on the receiver carefully and/or location
of both the camera and receiver for better receptions. Avoid setting
both receiver and camera(s) on other electronic devices, metal
objects, and away from magnetic shield devices such as refrigerators,
microwave ovens, other 2.4MHz products, etc.
Q4: Can other manufacturer camera(s) be used with the wireless
receiver?
A4: Yes, other manufacturer cameras can be integrated with the
wireless receiver. Make sure the camera(s) being integrated matches
the frequency channel of the wireless receiver; channel 1 = 2414MHz,
channel 2 = 2432MHz, channel 3 = 2450MHz, & channel 4 = 2468MHz.
Q5: What are possible interferences that exist?
A5: 2.4GHz cordless phones, satellite dishes, and 2.4GHz wireless
computer networks (Wi-Fi Router) are the top three products on
the market today that seem to cause interference problems with
wireless camera systems. Strong static interference, large horizontal
lines rolling upward, an increased noise level, and an unsteady
picture are all possible problems the wireless camera system can
produce. Please refer to the other equipment manufacturers for
exact frequency specifications. If the wireless camera is channel
selectable (not all models), please try to change channels until
an acceptable picture is displayed. When using multiple wireless
cameras, make certain they are using different channel numbers
and set them apart at least 2 meters (6.5 ft) from each other.
Q6: What is the viewing range of the 2.4GHz wireless indoor/outdoor
camera(s)?
A6: The industry term "Line of Sight" is a base measurement
for range. Our 2.4GHz frequency line of sight maximum distance
from the transmitter to the receiver is about 300 feet. However,
the maximum range for an indoor situation is about 100 feet and
depends on certain factors such as the thickness of a wall and
the number of walls/stumbling blocks between the camera and receiver.
A stumbling block can refer to human body, wood wall, cement wall,
or metal wall, which represent weak, medium, and stronger possibilities
of signal transmission.
Q7: What does 4 channel selectable mean?
A7: It means being able to manually change the channel on the camera.
Since other items that operate on the 2.4GHz wireless frequency
such as cordless phones, satellite TV dishes, and wireless routers
for computers produce a frequency in the same range, it is possible
to adjust your picture quality by changing the dipswitch position
on the camera (dipswitch feature is available on some camera models
and not all). By changing the camera’s frequency and carefully
adjusting the receiver antenna, interference can be minimized.
Q8: How many more wireless cameras can I add?
A8: The Mini-AirWatch and OutdoorWatch receivers can handle up
to a total of 4 cameras (can be mixed with SecurityMan indoor
and outdoor wireless cameras). Be sure to use different channel
numbers for each camera. Please use a receiver and 4 wireless
cameras in one location.
Q9: Can the wireless system connect to a PC and be monitor over
the internet?
A9: No. The wireless indoor and outdoor camera system does not
contain any software for pc connection (such as internet or remote
monitoring capability). In order to connect this system to a pc,
a DVR capture card or video recording card needs to be added on
to the computer, providing input jacks. Please reference the add-on
card instructions on how to hook up and operate.Q: Can I connect
the wireless system to my TV if there is only a coaxial input
and not the required A/V inputs?
A. Yes, if your TV has only the coaxial inputs on the rear and
not the A/V RCA style input jacks, you can still hook-up your
receiver with the use of a coaxial to RCA converter (an RF Modulator).
These are add-on devices that accept the coaxial cable from your
TV and the A/V cables from the receiver as inputs, sending the
signal to your TV. Then, turn on your TV, select channel 3, and
adjust your camera’s viewing angle.
Q10: Can I connect the wireless system onto a DVR to record?
A10: Yes. There are 2 options.
1. One channel recording: connect one wireless receiver to one
of the video inputs of the DVR. If there are four wireless cameras
connected to the receiver (loop mode must be on) the DVR will
record the four cameras in a one by one sequence. It is then possible
to review the recorded files in sequence or expand the picture
to full screen using the DVR buttons.
2. Multiple channel recording: example, connect four wireless
receivers (each receiver having a different frequency camera)
into the DVR’s four video inputs. All four cameras can then
be recorded simultaneously and it is possible to review the files
as a single camera display or as a quad display.
Q11: Does a wireless camera still need a power adapter?
A11: Yes it does. A camera wireless camera would not be operable
without some source of power to it. This source of power can come
from either the AC outlet (using the adapter) or from a 9 volt
battery.
Q12: Is there anyway to extend the distance of video transmission
for the wireless camera?
A12: No, due to FCC limitations on transmission power. It is possible
to use a high powered booster (i.e. 1 watt, 5 watt, etc..) to
extend the viewing range of the wireless camera system. Using
a power booster for these purposes is illegal in the U.S.A. and
restricted by the FCC.
MiniAirWatch
Q1: Is there a battery that can last more than 3 hours
on the indoor camera?
A1: Yes, please use a brand new 9 volt battery. A new battery can
last between 6-7 hours. The 9 volt battery provided in the original
package is good for temporary applications such as finding the
desired location or a temporary location for video surveillance
need. The camera picture will then degrade when this battery begins
to drain. Please note that the 9 volt battery will drain as long
as it is connected to the camera, regardless of whether the receiver
is on or off.
Q2: Can the Mini-AirWatch be used outdoors?
A2: No. It is designed for indoor usage. For outdoor security applications
please consider the OutdoorWatch (kit) or add-on outdoor wireless
camera SM-823T, which is designed to withstand outdoor weather
conditions and has a night vision capability.
Q3: How do I setup the camera stand?
A3: There are 3 pieces to a stand along with 2 screws. Looking
from the front view, the top piece is square (this holds the body
of the camera), the middle piece is triangular with a circular
diameter base of 15/16î (this piece clamps itself to the
outer base-notch of the square piece and tightens in with the
longer of the two screws), and the base is the circle piece which
is 1 and 5/16î in diameter (the 15/16î circular base
of the triangular piece seats itself on top of the 1 and 5/16î
circular base and tightens in with shorter of the two screws).
NiteCam2
Q1: I have both SM-202T cameras connected at once, but only one can display an image, what is wrong?
A1: It’s possible that each SM-202T camera was set to the same frequency (ie. Ch.1 2,414Mhz). Make certain that one of the outdoor cameras is set to Ch.4 2,468Mhz. The channel 1 & 2 switches, adjustable for up to 4 frequency combinations, are located on the rounded thicker area underneath the rubber flap, near the camera’s own power jack. The other available Ch.2 & 3 can be used to improve image quality should interference or statics become present.
Q2. Can I use a 9V alkaline battery to power on the SM-202T camera & stay completely wireless?
A2: No. The package does not include a 9V battery clip, & a 9V battery would not supply enough current to fully turn on the camera. For indoor use only, please consider the SecurityMan SM-BP3600 Lithium-Ion rechargeable battery, able to provide up to 18hrs of camera usage on a 3hr 15min charge time. The SM-BP3600 battery is not weatherproof, thus not designed for outdoor use.
