At present, video surveillance is very popular, but also gradually entered the family, units, supermarkets and other business places。Ball machine, gun machine, head of all kinds。Wired and wireless options are wide。
Let's start with home video surveillance options。Good quality domestic brands on the market, including Hikvision and Dahua (also on the MG blacklist of suppressed products)。Imported SONY, Panasonic and so on。Look at the after-sales, or choose domestic has the advantage, the quality is also very stable。In addition, the current video surveillance is basically with infrared。The home installed wireless infrared hemisphere camera with its own pickup is enough。Conditional installation wired HD better。It has the advantages of stable operation, high clarity, long irradiation distance and rich adjustable parameters。But for one thing, the mainframe must be placed in a hidden place and locked in a sturdy metal case to prevent damage。If you want to increase the security, you can install an alarm host connected to the host。A SIM card can also be inserted into the 110 alarm center for higher levels of protection。
For families, video surveillance installed at the first entrance and exit of the care home is most appropriate。Vertical Windows and skylights have weak points, you can install a monitoring nurse。If there is a second floor, it is best to install a pair of infrared targeting alarms, plus smoke detectors。In this way, whether an intruder or a fire is detected, you can make an emergency response in the first time。
Unit installation。 Such as supermarkets and large shopping malls, we must first consider important areas, followed by other areas and external environment。Important areas, whether rectangular or square, the monitoring should be installed diagonally。This kind of spaced corridor, to a camera control coverage, obstacle shadow influence irradiation, to install a camera, important areas must be fully covered, as small as possible to leave dead corners。Except for dressing rooms and bathrooms。
In terms of video Settings, depending on how many hard disks are installed in your monitoring host, set how long to save the video to configure parameters。Key channels can be set for 24 hours or motion detection video。Other channels and external environments can be recorded by setting time periods or motion detection。If the funds are sufficient, other channels and external environments can be better cared for by adding a head。
The monitoring host should be placed in a 24U cabinet and locked for safekeeping according to the requirements of the public security。Half a month to a month patrol to see if there are no working cameras (commonly known as blind);Is there any twisting of the camera, is there any other object blocking, dust covering the camera, etc。 The monitoring host must be restarted once a month (without data loss).。Due to the high working temperature of the host for a long time, the accumulation of log cache, the memory is not released, and it is easy to crash and record interruption, affecting the authenticity of case restoration. Therefore, the monitoring host must be restarted once every half a month to once a month。
