I. Distorted or unmarked lines in the process of integrated wiring
Here all system wiring is incorporated into the integrated wiring. The wiring system project is the longest construction cycle in the entire project, and the largest amount of manpower investment. It is also the most important part of the entire system. In the construction of the modern community, it is mostly a concealed project and they are all permanent links. In the wiring, there is often a phenomenon that the line marking is disordered or even not marked, leaving a lot of trouble for the installation, debugging, and maintenance of the project. The line is not marked when the equipment is installed and debugged. It is necessary to input the manpower twice to measure the line after the completion of the project. If the label is still not marked or even unmarked, it will cause difficulties for the maintenance work. Therefore, each line must be marked clearly in the wiring process. This will not only save installation cost, but also facilitate installation and debugging of the project. The reasons for this kind of site are mostly caused by the insufficiency of engineering management. The solution is to provide all-round training for construction personnel and strict requirements in construction.
Second, there is no waterproof sunscreen outdoor wiring termination
Lines that need to be outdoor terminated must have water and sun protection and other measures to delay the life of the system and system stability. Line terminations are susceptible to aging due to non-water-proof sun protection measures, resulting in system instability and the like, resulting in high rates of return repairs and even causing system defects in case of maintenance failures.
Solution:
1, in the indoor termination of the line as much as possible in the indoor termination, even if the extension of some lines, the bus system can be hand-in-hand wiring;
2. The outdoor termination part can be sealed to delay the aging. The disadvantage of this method is that it is inconvenient in the system maintenance and line maintenance. If the line needs to be dismantled, it must be resealed.
3, can increase the outdoor wiring box, all the outdoor termination of the line into the wiring box termination, this method not only solves the problem of outdoor termination waterproof sunscreen, and easy maintenance.
Third, the installation height of the intercom host is not suitable
Most intercom host installations are based on the bottom 1.5m of the host. However, because the heights of the hosts are different from each other, the height to be installed must be based on the entity. The height of the camera should be used as the standard. In order to make visitors more clearly visible on the indoor extension. Some cell units have a ladder in front of the door. This results in the height of the station where the visitor is not the height of the bottom door frame of the unit door, but the next or even two steps. Therefore, the height of the host installation site must be fully considered. Happening.
Fourth, the host is not rain
Some hosts are installed on the wall of the unit door, which may cause the host to be exposed due to the small canopy of the building body, which may cause the host to suffer from sunlight and rain, thereby affecting the stability and service life of the equipment.
Solution:
1. The door machine can be installed on the unit door so that it will not cause the main unit to burst out of the canopy;
2. If the host must be installed on the wall, it can increase the size of the canopy or add protective devices to the host.
Fifth, the closed circuit monitoring system in the same line and strong circuit
In the closed-circuit monitoring and wiring, the phenomenon of parallel and even the same pipeline with the strong electric circuit often appears. This phenomenon is mainly caused by poorly designed and unreasonable design, but it is not that we can arrange any wiring in this case. As long as we strive to strive for construction, we can still increase the stability and reliability of the system. Otherwise, the monitoring image will be seriously distorted.
Solution:
1, the use of better shielding or even double shielded cable;
2. It is possible to have multiple line tubes even in the same pipeline, and do not wire with strong circuits in the same line tube;
3, especially in the elevator wiring, because the elevator is a strong power, greater impact, we must strive for distance from the strong circuit, even if it is a centimeter will make the image signal several times better;
4, increase anti-interference equipment.
VI. Exposure of Householder's Privacy in CCTV System
The monitoring of the community is very easy to see in the homes of the residents. The privacy of the owners will be revealed unconsciously. If video data is transferred unjustly, it will cause great harm to the owners and may even cause a lawsuit.
Solution:
1. Install a suitable location. The cameras in the community should be installed mainly in public places such as squares and traffic arteries;
2, the camera should avoid facing the direction of the house.
Seven, parking lot reader location is not suitable
At present, readers in the market are ID and IC. Readable distances range from 10 to 10 meters. For medium-to-long-distance readers, the distance between readers is relatively long. Normal drivers do not take the initiative to take the cards. In the car waiting for the car next to the card reader will automatically read the card, and for the 10 cm proximity card reader, the driver must roll down the window out of the card in front of the reader to brush it to the reader to collect data , so the reader must be installed in the driver's most accessible position. In some quarters, due to site conditions, vehicle readers cannot turn in and out. Turning in and out cannot read cards properly, so that the driver must walk out of the car to swipe the card, causing inconvenience to the owner. Solution: Fully inspect the site and choose the right location to install the parking management equipment.
Eight, perimeter protection system is installed as normally closed alarm
The general alarm mode can be divided into two types. One is the normally open mode alarm, and the other is the normally closed mode alarm. However, the normally closed mode alarm is not suitable for use in the perimeter protection system because the normally closed mode alarm is normally open. In the normal state, when the signal line is disconnected due to some factors, the system still prompts for a normal state and does not alarm, and the normally open mode alarm will alarm as soon as the line is disconnected to achieve the purpose of automatic detection of the system. The choice of which type of alarm has its advantages and disadvantages, but the line break is much greater than the chance of short circuit, so I suggest that the normally open mode alarm in the perimeter protection system is more appropriate.
Nine, electronic patrol route is not suitable
Electronic patrols are divided into cable patrols and wireless patrols, because wireless electronic patrols have many advantages such as easy installation, simple maintenance, and stable system. They have gradually replaced the traditional cable patrol system, and bad patrol lines will make patrols. Distracted. It may make it necessary for patrolling personnel to enter the lawn to reach the patrol point, especially for the patrol personnel in rain and snow.
Solution:
1. The patrolling line should be designed and installed with S-type line to fight for no dead ends;
2. The patrolling point should be installed at a place easily accessible by patrol personnel, usually at the roadside, in front of the unit doorway, etc.
Tenth, home networking alarm system infrared detectors facing the window
The home-networking alarm system brings a sense of security to the households, but more false alarms can cause residents to be bothered. The level of false positives is not only related to the selection of the root product, but also has a close relationship with the installation of the equipment. Most of the anti-theft devices installed in the home are infrared detectors. If the installation of infrared detectors faces the windows and the electrical appliances with large variations in temperature, there will be more false alarms. The most common problem in installation is that the effective range of the detector reaches the outside of the window, so that outdoor environmental factors cause more false alarms.
Solution: Make the detector toward a stable indoor environment.
In the process of installation and debugging, there will always be such problems, but we should strive to reduce the occurrence of these problems, so as to avoid more problems and difficulties in the future use and maintenance.
