Community video intercom design

After installing the video intercom system in the community, residents can dialogue with outsiders through video communications and effectively prevent illegal intrusions. Now that the new residential quarters are beginning to install video intercom systems, how can the residential video intercom system be designed? The following solutions hope to help everyone.

demand analysis

It can realize video intercom between residential entrances and exits, stairways and occupants, and between management center and occupants. The voice and images of visitors can be clearly confirmed. Residents can contact the center through the emergency button for help. The system has eight custom zone alarm functions. The community is an intelligent community, and closed-end management is implemented. Building visual intercom is a system that occupies a large area of ​​intelligent investment in the community. The selection of equipment should be economical and cost-effective.

Appearance and use environment

(1) The outer surface of the plastic shell: smooth, no cracks, fading and permanent stains, no obvious deformation (shrinkage) and scratches

(2) The outer surface of the metal shell: flat, no obvious deformation and scratches, the surface coating can not expose the underlying metal, and there is no blistering, corrosion, gaps, burrs, pits, sand holes, and coating shedding.

(3) Buttons and switches: The operation should be flexible and reliable, the parts should be tightened without looseness, and the signs should be clear; the seals should be clear, and the certificate and label of each product should be clear, not misunderstood and difficult to clean.

(4) Protection capability: The mainframe, outdoor installation power box, shall comply with IP33; extensions, management machines, modulators, decoders, video distributors, sensor read heads, power boxes, alarm input devices, alarm output devices should be Conforms to the IP30 regulations; the housing of the main unit should be protected against abnormal disassembly.

(5) Logo: It should have the following clear and permanent logos, product specifications, power rating and major technical indicators. All manual controls shall be clearly marked with their purpose or icon symbol; corresponding characters or numbers shall be marked near the terminals; the conductors shall be numbered, coloured or otherwise identified.

Ambient temperature: -40°C to +45°C (outdoor equipment) -10°C to +45°C (indoor equipment)

Relative humidity: 10% to 95%

Stability requirements

(1) Continuous working time of the system: Under normal climatic conditions, continuous operation for 168 hours, no malfunction should occur (GA/T269-2001)

(2) System cycle working time: selective call, call, and electronic control unlocking under rated voltage, cycle 600 times, due to power failure or mechanical failure, there should not be equipment damage or contact adhesion, the key character is clearly identifiable .

(4) Average time between failures: Under normal operating conditions, the average is not less than 5000h

System Configuration

(1) Management Center: A color visual management center is installed in the management center. The management center computer can perform video intercom with the door-to-door machine through the system connection to realize mutual call and call functions between the user and the center.

(2) Doors of buildings and units: Install a black-and-white camera-headed visitor intercom door at the entrance of each building to allow the user to confirm the identity of the visitor and unlock the unit door. The user can monitor the situation at the entrance, and can directly talk with the management center; set the personal unlock password to unlock the access unit ladder password; and the owner can use the already set ID card to unlock the access control card.

(3) User indoor unit: A user indoor unit with a black-and-white indoor intercom visual band monitoring function is installed in each user's house. Not only can the door lock be unlocked, but also in a hands-free state, the management center can be directly called. Can call the occupant initiatively, the system requests to provide the emergency button to realize the emergency help.

basic skills

(1) Call function: After connecting between the host and the extension, two-way conversation can be realized, voice quality is clear, and no ringing phenomenon should occur.

(2) Surveillance function: After connecting the host and extension, the real-time image of the visitor captured by the host can be monitored on the extension monitor to identify the visitor.

(3) Networking function: Two-way communication can be realized between each extension and management machine

(4) Emergency call function: When an emergency occurs in a resident's house, an emergency call and an address code corresponding to each resident can be sent to the manager through the extension.

(5) Information release function: The management center should be able to send pictures and text information to the indoor unit. Indoor unit full screen display information content

(6) Alarm function: In the resident's house, professional zone alarms can be set up, and various alarm interfaces such as emergency buttons, infrared detectors, gas detectors, and door and window magnets can be provided. When an intrusion occurs in the house, the alarm condition can be immediately sent to the property. Security Center, indoor unit should have security features

(7) Access control function: online networking access control function can be realized through intercom system equipment

The above content is the residential video intercom system solution. The video intercom is the first line of defense in the residential community. After entering the household, the outsider can enter it. This is safe and convenient for the occupants. Therefore, the application of video intercom systems in the future will surely become more common in the community.
