Introduction to Perimeter Security

According to the different geographical environment and safety level requirements on site, different types of electronic fences can be used according to the actual situation to achieve outdoor safety protection. In order to make everyone understand the various electronic fences, the common types of electronic fences are introduced as follows:

(1) Electronic pulse electronic fence:

Function description: 
The electronic pulse fence is an active intrusion prevention system, which counters intrusion attempts, repels intruders, delays the intrusion time, and does not threaten human lives. The pulse electronic fence consists of electronic cables with charged pulses. The non-lethal pulse high voltage generated by the electronic cable can effectively repel the intruder and send the intrusion signal to the security department monitoring equipment to ensure that the management personnel can timely understand the situation of the alarm area and quickly deal with it.

Applicable places: 
Applicable to any place (such as: military bases, government agencies, judicial systems, key cultural relic sites, borders, private residences, real estate agents, industrial heavyweights, factories, warehouses, etc.). Install on existing perimeter fences, walls, or free-standing. The system automatically adapts to changes in environmental and field conditions. Varies according to regional conditions. For example, in foggy and windy weather, the system can maintain the highest alarm value. It is easy to construct, does not need welding, and will not be threatened by erosion.

(2) Buried fiber optic cable:

Function description: 
The buried optical fiber cable is composed of buried induction cable and intrusion detection sensor. Through invisible (buried underground) intrusion detection sensors, invisible electromagnetic fields are generated around buried induction cables. When someone interferes with the electromagnetic field, an alarm will be triggered to remind the management personnel to inspect and deal with the defense zone.

Applicable places: 
Suitable for outdoor and indoor areas without magnetic field interference. The electronic fence induction cable can be buried in any medium, such as soil, sand, clay, concrete and other environments, thereby forming a unified, concealed volume detection field based on terrain. Weather changes have little impact on it, such as rain, snow, wind and sand (but will have a certain impact on thunder days with magnetic field induction), and the safety is high.

(3) Vibration type electronic induction cable:

Function description: 
The vibration type electronic induction cable is composed of a vibration induction cable and a vibration sensor. Vibration sensors can be installed on existing enclosures and walls. For the fence, any real attempt to climb or break the fence will be detected, and the alarm will be activated to alarm. For the perimeter fence, the vibration sensor and sensor cable are attached to the existing fence. The vibration of the peripheral fence is received through the vibration sensor. For attempts to climb the cut, set off behavior. Will cause the alarm of the alarm.

Applicable places: 
Applicable to outdoor fences and outer fences (such as: chain mesh, welded mesh, barbed barrier mesh, etc.). This system has little effect on weather changes.

(4) Tension-type electronic cable cover:

Function description: 
Tension type electronic wire is composed of ordinary metal wire and tension detector. This system connects various types of regular wires through tension detectors. Each tension detector converts any manpower and mechanical force (force change) that attempts to climb and cut the wire into an electronic signal and transmits it to the control Center to achieve the purpose of alarm.

Applicable places: 
It is suitable for outdoor fences made of metal wires (such as ordinary wire, double braided wire, barbed wire, etc.). Weather has little effect on this system. Mostly suitable for military facilities, airports, industrial sites, petrochemicals, etc.

(5) Microwave radiation:

Function description: 
Microwave radiation consists of a microwave sensor (generally composed of a transmitter and a receiver) that is separated from the transceiver. By establishing an invisible microwave space energy field between the transmitter and receiver. The receiver will generate an alarm for any attempt to cross the area.

Applicable places: 
Suitable for indoor and outdoor, according to different environments (such as: open space, etc.) can be customized installation method. The impact on climate change has increased.

Other Door Accessories

Sectional Door Accessories: motor 220V-380V, control box, spring break device, cable break device , aluminum alloy rope pulley, enhanced shaft bracket, air bag system, duplex enhanced guide wheel bracket.

Detail introduction for above main accessories

1.Motor and controller:

The garage door operator is designed for residential overhead sectional and tilt doors.

The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel.

Rolling code remote control with max. 20 pcs hand transmitters.

The operator is equipped with a manual release lever which allows manual operation of the door in case of power failure.

The controller has a security LOCK function which prevents operation of the door from transmitter.

2.spring break device:

Sectional doors are hinged and they bend in the tracks as the door opens and closes. Many of these doors are counterbalanced with extension springs, also designated "stretch springs," and they have seven characteristics. The length is the measurement of all the coils pressed together. This, along with the inside diameter of the coils and wire size - the thickness of the wire from which the springs are made - determine the stretch, the distance the spring is extended - normally half the door height, and pull, the force the spring pulls when stretched its normal length. The type of ends determine how the ends of the spring are mounted. The initial tension is the percentage of pull needed to separate the coils. This is determined by the pitch with which the springs are wound. On sectional garage door springs this is normally 15 percent. For example a 100 pound pull spring requires 15 pounds of weight to separate the coils; when a door is open the two springs will support 15 pounds of door weight without any stretch.

Most extension springs are made of oil tempered wire. These are normally coated or painted. Some springs are made of galvanized wire.

Determining the right type of sectional door roller for your garage door tracks can be a little confusing, especially when you do not know what you need to look for in a garage door roller. To simplify things, there are two primary things you need to be aware of. First are the actual dimensions of the roller, and second is purpose that you will be using the door for. You can read below about measuring your roller and choosing the right quality of material for your door.
