I. PRODUCT FEATURES
a) What is a network video server?
Answer: TeleEye NX301 network video server converts analogue cameras’ video into IP-based streams and transmits this video through the LAN, Internet and mobile network.
b) Why you need a network video server?
Answer: When there are many existing analogue cameras installed in different sites, users can use network video server to converts these analogue cameras to IP-based that allows cameras to transmit video through different network directly.
c) What are the advantages of using network video server?
Answer: Users can enhance existing security CCTV system by just adding a network video server to converts existing analogue cameras to IP-based with lower cost relatively. It adds value to existing network infrastructure and can lower the cost of ownership.
d) What is switchable IR-cut filter?
Answer: The IR-cut filter can be switched automatically under different environment. The IR-cut filter is on when there is in daytime with a sufficient lighting. The IR-cut filter is off where there is at night with an insufficient lighting and the camera changes to monochrome mode.
f) What is the advantage of the auto iris IR lens?
Answer: Since the wavelength of IR light is significantly longer than that of visible light, the focus of ordinary lens will be shifted between daytime and IR operation, making the image blur at night-time. The built-in auto-iris lens with zero focus shift in TeleEye IR cameras produce sharp images under both visible and IR illuminations environment.
e) What is back light compensation (BLC)?
Answer: BLC is a technology that allows cameras to adjust the light level compensation to fit the environment and provide a clear images and video.
f) What is 3-axis adjustment?
Answer: The lens in a camera can be rotated horizontally or vertically. The camera can be mounted to ceiling, wall or slope. The viewing angle can be adjusted easily after installation.
g) What is auto gain control?
Answer: Auto gain control is to maintain a constant output voltage by adjusting the amplifier automatically even the input voltage is unstable.
