SECTION 1: SYSTEM OVERVIEW
What you need
The DVR is the central component of your security system. To install the DVR, you need: :
• PC compatible monitor
• Uninterruptible power supply (UPS) (highly recommended). This device is used to ensure system stability during voltage
surges, sags, and outages. If a UPS is not available, a power strip with strong surge protection is highly recommended.
To have a functioning system, you also need: s
• CCTV (analog) security cameras. The DVR9004N, DVR9008N, and DVR9016N DVRs support many camera models.
• Microphones for audio monitoring (optional)
• Extension cables for the cameras with cable adapters ( if needed) to connect to the DVR (BNC video terminations, RCA audio
terminations)
• RS485 extension cable (for PTZ cameras). Consult your local electrical codes for gauge and shielding requirements.
• Powering equipment to support the cameras (usually provided with each camera)
• Access to an Ethernet LAN (optional) to use the networking capabilities of the DVR
• Tools to install the cameras and route power and video extension cables
• Fasteners to attach the cameras to the mounting surfaces
