This document describes the KOCOM KVM-624 Video Doorphone, a system designed for home security and communication. It provides detailed information on its functions, technical specifications, usage, and maintenance.

Function Description

The KOCOM KVM-624 Video Doorphone serves as a communication and security device for residential use. It allows users to identify visitors, communicate with them, and even open the door remotely if an automatic door opener is installed. The system comprises a monitor (KVM-624) and one or more door cameras (KC-D33 or KC-MB20).

Visitor Identification and Communication: When a visitor presses the call button on the door camera, the monitor's screen automatically turns on, displaying the visitor's image, and a call signal rings. The user can then pick up the handset to communicate with the visitor. The screen remains on for 3-4 minutes during communication or until the handset is replaced. If communication continues for more than 3-4 minutes, the monitor screen will turn off automatically.

Checking Out Door Side: Users can proactively check the outdoor area by pressing a camera button on the monitor. This action turns on the screen automatically, displaying the outdoor view for approximately 3-5 seconds before turning off.

Identifying Visitors Without Handset: The system allows for visitor identification without needing to pick up the handset. When the call button on the door camera is pressed, the monitor screen turns on automatically, displaying the visitor's image for about 30 seconds, enabling easy identification.

Automatic Door Opening: For enhanced convenience, the doorphone can be integrated with an automatic DC door lock. After communicating with a visitor, pressing the "Door Key" button on the monitor will automatically open the door. This feature requires the prior installation and connection of a compatible automatic DC door lock.

Monitor Controls: The KVM-624 monitor features a 4-inch flat monitor for clear viewing. It includes "Camera1" and "Camera2" buttons to view visitors from respective cameras without lifting the handset. A "Door Key" button facilitates automatic door opening. A "Brightness Control Knob" allows adjustment of the monitor screen's brightness, and a "Call Signal Volume Control Knob" manages the volume of the incoming call signal. The handset is used for two-way communication.

Door Camera Features: The door cameras (KC-D33 and KC-MB20) are equipped with a pinhole lens camera for capturing images, a C-Mic for audio input, and a speaker for audio output. A "Call Button" is present for visitors to initiate a call to the house. A "Power Lamp" indicates the ON/OFF status of the camera.

Usage Features

Installation Precautions:

Location: Both monitor and camera must be installed away from direct light and counter light. The camera should be installed in a rain-free location.
Monitor Height: Standard height for the monitor is 1,450mm ~ 1,500mm from the ground, centered around the braun tube.
Camera Height: Standard height for the door camera is 1,400mm ~ 1,450mm from the bottom of the camera to the floor. Care must be taken with camera height to ensure the lens angle covers the desired view.
Environmental Factors: Avoid installing in humid places, near heat sources (dresser, humidifier, heater), areas exposed to dust, metals, harmful gases (like hydrogen sulfide), water, chemicals, or strong magnetic fields (TV, speaker).
Wiring: Use designated wiring materials. Communication cables should be installed separately from power cables to prevent interference. The wiring for monitor-to-monitor communication is 7-wired, with specific cable types and maximum distances (e.g., TIV 0.65 for 50m, Coaxial cable for 100m). Door opener cable should be TIV 0.5 or above for a maximum of 10m.
Temperature: If installing during winter at temperatures below -5°C, allow 2 hours or more after installation before connecting to prevent condensation.
Pipe Sealing: Seal PVC pipes with adiabatic substances to prevent air circulation, which minimizes temperature differences and moisture/condensation on the door camera window.

Operation Guidelines:

Cleaning: Never use wet hands, volatile benzene, or paint thinner for cleaning. Regularly clean the camera window with soft cloths to maintain clear picture quality.
Handling: Avoid dropping the monitor or door camera and protect them from strong impacts.
Disassembly: Do not attempt to disassemble the device, as it contains electronic precision components and generates high voltage internally.

Maintenance Features

General Maintenance:

Cleaning: Regularly clean dust from inside the product. Failure to do so can cause fire. For internal inspection and cleaning, contact a local sales agent.
Power Disconnection: Always ensure the power plug is detached from the outlet or circuit breaker is turned off before putting hands inside the equipment.
Chemicals: Do not expose the product to benzene, thinner, hot water, or spray detergent directly onto it.
Moving Equipment: Always detach the plug from the outlet when moving the equipment.
Cable Connections: For equipment with cables connected to terminals, contact a local sales agent or qualified electrician.
Fuse Replacement: Use insulated tools or contact an A/S center when replacing fuses.

Troubleshooting (Cautions for Abnormality):

Broken Power Cable: If the power cable is broken (exposed core or short-circuit), replace it immediately with a new one to prevent fire and electric shock.
Abnormalities: If communication is unavailable, images are not displayed, calling is not possible, or abnormal sounds are heard, immediately detach the plug, turn off the circuit breaker, or remove batteries (if applicable). Then, request repairs from a sales agent or A/S center.
Foreign Substances: If foreign substances enter the equipment, immediately detach the plug, turn off the circuit breaker, or remove batteries (if applicable). Then, request repairs from a sales agent or A/S center.
Smoke or Smell: If smoke or an unknown smell emanates from the equipment, immediately detach the plug, turn off the circuit breaker, or remove batteries (if applicable). Ensure no more smoke or smell is present before requesting repair. Do not attempt personal repairs.
Physical Damage: If the equipment is dropped or its cabinet is broken, immediately detach the plug, turn off the circuit breaker, or remove batteries (if applicable). Then, request repairs from a sales agent or A/S center.
Storage: Avoid direct exposure to sunlight and store the equipment in a dust-free, low-temperature environment to prevent fire and electric shock.

Warranty: KOCOM provides a one-year free repair warranty from the date of purchase for product defects under proper use. However, the warranty does not cover breakdowns due to:
