Night Hawk™ FAQs
What kind of image quality can I expect from the Swann Nighthawk Camera?
The Swann Nighthawk Camera has a 1/3” color CMOS image sensor and a resolution of 380 TV Lines or
628 x 582(PAL), 510 x 492(NTSC).
CMOS stands for Complimentary Metal Oxide Semiconductor. CMOS sensors are medium quality sensors that are com-
monly used in digital cameras and many low-powered image devices such as USB webcams. CMOS sensors usually don’t
handle variations in light conditions as well as CCD image sensors and are less sensitive so are not as powerful in low light
conditions.
The Swann Nighthawk Camera is wireless for video transmission so you may occasionally see lines or hear static on the
screen. If this disturbance is excessive try the following to improve the picture quality:
•
Look for other wireless devices such as cordless phones and wireless LAN’s that operate in the same area and
could potentially interfere with your camera. If possible, try switching these devices off to identify whether the
picture quality of your Nighthawk Camera improves.
• Since walls and other physical barriers may generate some interference, position your Swann Nighthawk Camera
as close to the receiver as possible.
• If you are using less than four cameras with your wireless receiver, try setting the switch at the front of the
camera to a different channel. You may do this by removing the weatherproof cap from the front of the
camera and changing the configuration of the switch located at the left side of the lens. Sometimes you will
receive better picture clarity when the camera is transmitting at a different frequency. Adjust your receiver to
the new channel accordingly.
• Connect your camera to the AC power adapter rather than the 9V battery. As power is drained from the battery
you will notice a decline in the image quality of your Swann Nighthawk Camera.

How does the Swann Nighthawk camera work?
Wireless video transmission is made possible with the use of video transmitters and receivers. The Swann Nighthawk
camera comes with a built-in video transmitter and a separate video receiver. The video signal is sent wirelessly through
a specific radio frequency (2.4GHz) to the receiver which is connected directly to a TV, monitor or VCR using an RCA
AV cable.

My Swann Nighthawk Camera worked for a few hours before the screen went black. Is it faulty?
The Swann Nighthawk Camera is packaged with a 9v battery and an 8v power adapter. If you decide to connect the
camera to the supplied battery it will make the camera kit totally wireless but you will notice that the video quality will
deteriorate as the battery is drained within 3 – 6 hours. If the screen does go black and you have the camera connected
to a battery, plug it into the 8V AC power adapter to determine if it is an issue with the camera or the battery.
?
Is the Swann Nighthawk Camera totally wireless?
The Swann Nighthawk Camera is wireless for video transmission. Both the wireless camera and their receiver should be
powered by electricity to function over long periods of time. They should be located within 6ft (2m) of a power source
and plugged in. A Swann wireless receiver uses an RCA AV cable to transfer the video signal received from a Swann
wireless camera to your TV, monitor or VCR with AV connections, so must be located near your TV, monitor or VCR.
?
What is the maximum wireless transmission distance of the Swann Nighthawk Camera?
Due to the many variables in building construction and other causes of interference, the useful range can vary but is
usually around 150ft (45m), depending on local conditions.
