A database of signals from the effects of various weather conditions, animals and birds was recorded at its own 0.5 Ha test site. The main factors that worsen the tactical and technical characteristics of optoelectronic and vibration detectors have been identified and systematized. To improve the noise immunity of signal generation, algorithms for nonlinear digital signal processing were synthesized and investigated, as well as special optical filters were selected that significantly reduce the effect of solar glare. Today, time has proven that with proper installation of the SPLAV detectors, neither weather conditions, nor birds, nor sunlight lead to false alarms.
The circuit design solutions of the detectors are minimized to the analog part with a significant mathematical load, coupled with micro-consuming algorithms, which led to long-term autonomous operation from a single battery and fantastic reliability of the devices. Thus, during the entire period of mass production of the SPLAV L50RA detector, there were only a few cases of their failure solely after mechanical impact, for example, snow falling from the roof. Therefore, with an official 24-month warranty, the company often continues to service the sold devices free of charge, as long as they are of interest to the buyer.
Unlike radio-beam systems, passive infrared detectors "SPLAV" do not emit anything, do not have any mutual influence on each other and are not so sensitive to the underlying surface.
Radio channel detectors of the RA, RA2, GSM series with autonomous power supply are extremely convenient for installation, since no cable laying is required. One battery is enough for 7 years of battery life with one alarm per day, and the GSM version battery charge is up to 2 years.
The wired versions of the L50, L70, and V10 mini detectors have both normally-closed and normally-open contacts.
For autonomous radio channel detectors, integration with many security systems is possible through the relay outputs of receivers or open collector expanders.
All the devices offered by ZHURIN ELECTRONICS to create complex systems are easy to install, configure and operate. For example, to deploy the SPLAV-DBK complex (a mobile perimeter security kit), no special knowledge is required, no installation and connection of wires are required, or sensitivity is adjusted. It is enough to arrange the sensors so that the perimeter is blocked, check the system for activation and you can be sure of the safety of the object.
