LOGOUT

It is recommended that you log out from your

DVR when you will be away from it for an

extended period of time - especially if others

have access to your system.

This will not shut down the DVR, but merely

require that a user log back in to control the

system.

SETTINGS

Unlike computers, the DVR does not store its operating system (ﬁrmware) on the hard drive,

but instead it stores it on the mother board so your settings will be retained even if you switch

hard drives. You are able to backup your settings onto a USB drive much like a video ﬁle. This

is useful if you are experimenting with optimizing your settings and do not want to start over

from the factory defaults if you do not like the results.

You are also able to restore the factory

defaults using this menu.

6.1 CONNECTING A PTZ CAMERA

Some QS-Series DVRs can support one or more Pan/Tilt/Zoom, or PTZ cameras. These

cameras connect to the DVR through the same ports as a conventional camera, but the

control wires connect through the RS485 block on the back of the DVR. Picture 6-1, below,

is only a representation and your actual connector may look different. Please consult Chapter

2 Installation and Connection to ﬁnd the diagram representing your model for the

location of your connector block.

The RS485 connector uses a single-direction protocol meaning that it can send commands

out to the camera(s) but not receive any data back from the unit. Video images will be

delivered through the video cable as with any other camera.

The DVR is set by default for RS485 to be disabled for each channel. Therefore, PTZ settings

must be enabled before PTZ cameras can be utilized. This system supports 26 of the most

common protocols including Pelco-D and Pelco-P.

When connecting a PTZ camera, the following should be taken into account:

• The 485 port of this DVR cannot parallel connect with the 485 port of another device

• The voltage between the A and B lines of the camera should be less than 5V.

connected to this port, but you may

require an expander port to do so.

STEP 2. Connect the other end of

the cable to the proper pins in the

connector on the camera

STEP 3. Connect the camera video and

power cables as you would any other

camera.
