FAQs
Can I add extra wireless cameras to my Swann Nighthawk Camera pack?
Yes, the Swann Nighthawk Camera can be set to any of 4 channels the receiver is capable of using but you will not be able 
to view two wireless cameras on the same frequency or channel at the same time. Each additional camera must be set to a 
different channel on your receiver. 
Swann recommend a maximum of 3 wireless cameras for optimum reception quality but 4 cameras can be set up 
successfully with careful camera placement. 
?
Can other devices interfere with the Swann Nighthawk Camera?
Yes, some common causes of interference are Wireless LAN equipment, cordless 2.4GHz telephones and microwave ov-
ens (while they are actually cooking). Using the Swann Nighthawk Camera which has 4 switchable channels will allow you 
to change to a channel that is further away from the interference source to minimize the potential for lines and noise 
on your screen/recording.
?
How do I connect my Swann Nighthawk Camera to a TV/VCR?
The Swann Nighthawk Camera receiver comes with an AV cable which plugs into the Video ‘in’ and Audio ‘in’ connectors 
on your TV or VCR. These plugs are commonly referred to as ‘RCA plugs’ and are similar to the connectors used by game 
consoles and DVD players. If you plug your Swann Nighthawk Camera’s receiver into your VCR so that you can record 
the footage, you will need to select the AV channel on your VCR and then the channel on your TV that you normally use 
to watch video movies from your VCR.  If you plug your Swann wireless receiver directly into your TV, you can view the 
images on the appropriate AV channel, but you will not be able to record. 
?
Can I use my Swann Nighthawk Camera outdoors?
The Swann Nighthawk camera has an enclosed metal case and weather resistant cap to make it suitable for outdoor 
applications. Weather resistant cameras are able to be used in the outdoors if shielded from direct sun, rain, temperatures, 
snow and wind. Camera power supplies must never be left exposed.
?
How far can I see during the day with the Swann Nighthawk Camera?
In daylight it is most useful to measure the optical range of the camera in terms of Distance to Subject (DTS). DTS is a 
measurement of the ideal distance to view a subject from a camera viewing a 6ft/1.8m tall person from head to toe on a 
standard television. This assumes the camera is viewing from 3ft/0.9m off the ground. 
The DTS for the Swann Nighthawk Camera is 2.5m. 
?
I have more than one wireless camera. Can I view or record these cameras simultaneously?
The Swann Nighthawk Camera receiver is only capable of displaying an image from one wireless camera at a time. To view 
or record more than one camera you must set the switch at the back of the receiver to ‘Loop’. This will make the wireless 
receiver automatically cycle through the 4 channels sequentially, and linger on each for about 5 seconds before repeating 
the sequence.

What is ‘infra-red’ night vision?
Infra-red night vision allows cameras to ‘see in the dark’. It is the method of using IR LEDs (Infra-red Light Emitting Diodes) 
as illumination for a camera with a sensor that can ‘see’ infra-red light. Infra-red light provides the illumination needed to 
capture clear images in total darkness or low-light conditions. 
?
How does ‘infra-red’ night vision work?
Infra-red light is a part of the light spectrum that is not visible to the human eye. When there is insufficient visible light to see 
an object a Swann Nighthawk camera automatically activates its IR mode and sees the light from the IR LEDs using its IR 
image sensor. The resulting image is displayed as a black & white picture on your screen.
