Security monitoring engineering maintenance

Daily maintenance of maintenance personnel:

   Software maintenance:

1. Check the video playback regularly to prevent the video settings from being changed due to accidental situations.

2. Regularly check the video playback, and check the video playback to find if there is a period of time when the video is not recorded, so as to find the problem and prevent the loss from being recorded during this time when the accident occurs.

3. Regularly check whether the monitoring is recording, to prevent the software database from being damaged due to a sudden power failure. If the database is damaged and not repaired, then the situation that the recording cannot be made will occur, and then the database must be repaired manually.

4. Regularly check the operating system log to prevent damage to the hard disk and prevent the system from recording

Hardware maintenance:

1. Keep the computer environment of the monitoring system clean and prevent too much dust, high humidity, and high temperature from causing problems with hardware such as hard disks and system motherboards.

2. Regularly check the system wiring to prevent disconnection or leakage.

3. Regularly check the connection of the equipment to prevent the loose connection between the wire and the equipment, which will cause the equipment to work abnormally

4. Regularly check the connection between the network cable and the device to prevent the network cable from falling off and loosening to cause the system to work abnormally

5. Regularly clean the front-end camera to prevent dust from affecting the monitoring effect for a long time.

6. Regularly check the outdoor protective devices to prevent the equipment from being destroyed.


A small compilation of security knowledge

Access control system

The access control system is a brand-new access management method: allow persons with authority to enter the designated area, and reject persons without authority. The protagonist of the system is the card reader or password keyboard installed on the door side. They transfer the read data to the local controller, and confirm whether they can pass according to the database compiled in advance.

  CCTV

CCTV is an effective tool to prevent the loss of items, capture important suspects, and record the entire incident process in modern collective activity venues. The complete monitoring system includes: camera, matrix, picture splitter, control equipment, and digital video recording. ICD has extensive practical experience in this field. Whether it is a surveillance system for small offices or a large-scale complex surveillance system, ICD is also trustworthy.

Biometrics

Biometrics uses computers and advanced scanning technology to make use of the uniqueness of certain physiological characteristics of the human body for identification. With the development of PC technology, the speed of PC has made remarkable progress, the price is no longer expensive, and the application of biometric technology in access control is more and more accepted by people.

Fingerprint recognition

Fingerprint recognition is based on the fingerprint of a single finger.
Fingerprint recognition is an image analysis of the fingerprint of a single finger. The registration time takes 5 seconds, and the recognition time only takes 1 second.
The fingerprint machine also supports proximity cards, magnetic media cards, smart cards, and strip cards. The standard capacity of fingerprint storage is 512 people, up to 32,000 people.

Palm recognition

The palm shape recognition machine scans and records the three-dimensional images of four fingers and part of the palm as the recognition object.

Iris recognition

The iris is more unique than fingerprints, and even twins will not have the same iris.

Selection of protective cover and protective cover

The protective cover is an important component in the monitoring system. It is a protective device to make the camera work normally under the conditions of dust, rain, high and low temperature, etc.

Protective covers are generally divided into two categories. One type is a protective cover for indoor use. This protective cover has a simple structure and a low price. Its main function is to prevent the camera from dusting and has certain security protection functions, such as anti-theft and anti-vandalism. The other type is the outdoor protective cover. This protective cover is generally an all-weather protective cover, that is, it can make the camera installed in the protective cover work normally regardless of the harsh conditions such as wind, rain, snow, high temperature and low temperature. Therefore, this protective cover has the functions of cooling, heating, rain and snow. At the same time, in order to enable the camera to take images normally in rain and snow, a controllable wiper is generally installed in front of the glass window of the all-weather protective cover.

The current all-weather protective cover is a protective cover that uses semiconductor devices to heat and cool. This protective cover is equipped with semiconductor elements, which can be automatically heated or cooled, and the power consumption is small.

In addition, there are hemispherical and spherical protective covers. These protective covers have a universally adjustable bracket and have a beautiful shape.

The protective cover is divided into indoor type and outdoor type. The indoor protective cover is mainly dustproof, and some also have a concealing effect, making it difficult for the monitoring occasions and objects to be monitored. The function of the outdoor protective cover is to protect the sun, rain, dust, frost and condensation. Generally, the outdoor protective cover is equipped with a temperature relay, which automatically turns on the fan to cool when the temperature is high, and automatically heats when the temperature is low. When it rains, the wipers can be controlled manually. The glass of some outdoor protective covers can also be heated. When there is frost on the protective cover, it can be heated to defrost.
