Two-way communication energy-saving and efficient long-distance transmission intelligent protection

With the development of society, people have raised the need for indoor security, and smart wireless alarms have appeared in people's eyes. The wireless alarm device for this test is the Hikvision DS-PWB1 wireless alarm kit. Hikvision DS-PWB1 wireless alarm kit is a wireless alarm system consisting of a wireless alarm host, a wireless passive infrared detector, a wireless emergency button, a wireless remote controller and a wireless door sensor. They are responsible for each other and at the same time they are linked to each other to provide comprehensive security protection for users of small and medium-sized projects.

The host in this wireless alarm set supports Ethernet, WIFI, GPRS three communication methods to upload alarm information to the management center, and can set main and standby redundancy. The two-way 433MHz wireless RF communication is used between the host computer and each detector. The communication distance is long and the data transmission is safe and reliable . The alarm set adapts to the working temperature range of -10°C to +55°C, and the working humidity is 10% to 90%. There are many installation scenarios. Configuration and operation with voice guidance prompts, more intelligent.

Smart Wireless Alarm Host

The size of the wireless alarm console is 130.06mm×130.33mm×22.99mm, and the weight of the bracket is 356g. It can be placed directly on the desktop without the weight of 257g. It can be installed on the wall . The power input is DC5V, and a spare lithium battery can be installed at the same time. When the power is off, it does not affect the use of the device. The lithium battery (3000mAh) for charging and discharging can be normally standby for 8 hours. The transmission frequency is 433MHz, the transmission distance is up to 800 meters in the open area , the channel bandwidth is 20/40MHz, and the measured transmission signal passes through the two walls and weakens. If you need to transmit farther or penetrate more walls, you can install signal relay. Device, effectively increase the transmission distance.

Wireless alarm host interface includes a mini USB2.0, an RJ45 network port, a speaker output, and built-in Reset key. Which supports the cover tamper host, was immediately disassembled upload alarm information, the alarm information transfer AES-128 encryption. The host supports the heartbeat detection function and automatically detects the detector's online status at certain intervals to prevent the probe from dropping and the platform does not know. In addition, the host supports automatic detector registration, the host transmits a broadcast, and the detectors within the coverage automatically recognize the registration.

In the whole system, the device plays the biggest role in the linkage control and alarm information sending , its configuration is simple, the entire operation voice guidance prompts , WiFi function can be configured with a key, a wireless host supports 32 wireless zones, 8 wireless Remote control, 32 network users. At the same time because of the use of wireless WiFi connection network , thus avoiding the cumbersome wiring.

Four smart supporting equipment

If the smart wireless alarm host is likened to the brain, other detection devices are eye, nose and other sensing organs. Each detection device can have a built-in battery, which can be used for about two years after the battery of the required model is powered on. It is not necessary to install a power cord , is easy to install, easy to debug, easy to maintain, safe and stable, and is more suitable for security operations .

Wireless door magnetism : consists of two parts, through magnetic connection, when the magnetic force disappears, it will automatically generate alarm information and send it to the gateway. Suitable for doors, windows and other environments. The size is 84mm × 25mm × 20.99mm, weighs only 37g, support (pre-shell, back cover) tamper switch, when the alarm is triggered, the indicator light shows red, and transmits the corresponding alarm information to the alarm host.

Wireless button : the size is 70mm × 29mm × 15mm, weight is only 22g, support tamper switch, the user can use the wireless button for emergency help, when the alarm is triggered, the indicator light shows red, and transmits the corresponding alarm message to the alarm host.

Remote control : The distance of the remote controller in the open area is 300m. When the button is pressed, the indicator lamp is red. It contains 5 buttons, namely, arming (at home, going out), disarming/alarming, and emergency assistance, which can realize arming and disarming. , emergency help, wireless remote control and other functions.

Wireless passive infrared : size is 117mm × 63mm × 46mm, weight 140g, with 2 tamper switches, installed in the height of 1.8m ~ 2.4m, the detection range of up to 12m, detection angle of 85 °, monitoring speed of 0.3 ~ 3.0m/s, the infrared detector's LED light contains the signal, power, alarm, tamper-indicating functions, and the detection alarm is quickly detected after the arming.

Two-way communication energy-efficient

Hikvision DS-PWB1 wireless alarm set mode two-way radio frequency communication 433MHz, frequency modulation is not easy to break, two-way communication to trigger an alarm after only two packets, i.e., sending an alarm and return alarm signal received, the host power <5.6 W, low power consumption, low interference. The one-way communication of other conventional alarm devices triggers five consecutive bursts of alarms, resulting in high power consumption and large interference.

The two-wire communication between wireless alarm kits also has anti-replay attack capabilities . Each time it sends a different packet, the data packet fails in time. Automatic power adjustment is also supported to reduce interference and reduce power consumption. In addition, after the user is disarmed, the detector can enter a sleep state, wake up again when armed, and save more power. The detector supports self-contained battery undervoltage alarm reporting. After undervoltage, it can work normally for 1-2 months , fully demonstrating its energy saving.

Platform and Mobile App Management

Hikvision DS-PWB1 wireless alarm kit is matched with its professional software iVMS-A100. The software management center can realize functions such as remote arming and disarming, configuration, alarm cancellation, and video review . It is worth mentioning that the software can import electronic maps. More intuitive to add equipment, view alarm information, electronic maps can also be tampered, anti-repeated to add equipment.

The wireless alarm set supports the mobile phone APP function. It can realize the timely delivery of alarms, remote arming and disarming, and can link video applications.
