The AX-70TN Indoor / Outdoor Wired Short-Range Photoelectric Detector from Optex is compact in design with an IP65-compliant, highly durable structure. Rubber packing is used for all conceivable points where water, dust, or bugs may penetrate, such as wiring holes, wire ports, and the outer chassis. Preventing these factors helps deliver performance with higher reliability in severe outdoor environmental conditions. In addition, the length between the upper and lower optics and the width of the optics are ideally engineered to produce an intelligent detection pattern, which reduces false alarms by detecting only human intruders.

Featuring two Fresnel lenses, the ISC-BPR2-WP12 Blue Line Gen2 Pet-Friendly PIR Motion Detector from Bosch provides accurate motion detection within its wide, 94° field of view. It covers a large 40 x 40' area with its 77-zone, 7-layer pattern lookdown lens and features up to three selectable lookdown zones. This detector features a pet immunity function, which allows it to distinguish between humans' and pets' motion. It can negate signals caused by one or two pets, up to 45 lb each.

First Step Processing (FSP) technology analyzes motion, limiting false alarms. For increased reliability, the detector's sensitivity is automatically adjusted based on signal amplitude, polarity, slope, and timing. The detector also adjusts its sensitivity to compensate for weather, ensuring accurate operation in varying weather conditions. Installation is quick with its self-locking enclosure and built-in bubble level.

Once the Hue Motion Sensor Detector from Philips is connected to your Philips Hue Bridge via the Philips Hue app, it will automatically turn your Hue lights on when motion is detected. This sensor is wireless and runs using battery power, making it suitable for use in hallways, bathrooms, basements, garages, and more. The app lets you choose which scene or lighting setting should be triggered when motion is detected, such as a crisp white light or a gentle night light, with further adjustments that be made using the integrated daylight sensor. Once motion is no longer detected, the lights will automatically turn off.

Please bear in mind that a Philips Hue Bridge is required for use.

The VX-402R Multi Stabilized Wireless Outdoor Detector from Optex is a 40 x 40' wireless-ready, outdoor detector that provides the necessary stability and reliability for an outdoor PIR sensor. This battery-powered detector includes a backbox that accepts most manufacturer's wireless transmitters and allows installers to save valuable installation time and labor costs because no trenching, installing conduit, or pulling wire is required. False alarms from animals as well as environmental nuisances are greatly reduced with its design and dual PIR detectors. The VX-402R's dual PIR's create two detection areas (upper and lower) that must be simultaneously compromised in order to go into alarm. In addition, the detection length can be limited to avoid unwanted detection. By limiting the detection range, false alarms due to unwanted movement such as cars, people, or animals outside the protected area can be eliminated.

The battery-operated detector is compatible with all existing wireless technology, thereby allowing for low cost simple outdoor installations, while providing high detection capability.

B&H # BABE12594 MFR # BE12594

The Pursuit-200 Metal Detector from Barska knows the difference between trash and treasure, so you won't waste time digging up bottle caps and nails while more important objects wait to be discovered nearby. Its LED display shows what a buried object is likely to be; you can search for specific types of objects with the Discriminate function, and ignore certain types with the Notch function. The Elite-200 is sensitivity-rated to find a quarter buried 8.7" deep.

The detector has a built-in speaker, but there's also a 3.5mm jack for user-supplied headphones if you want to hear the detector's signal tones more clearly. The 10" search coil is sealed for water-resistance and can be used in shallow water. A low-battery indicator warns you when it's time for a fresh power supply. The detector's stem extends to 47" and is equipped with an arm rest for comfortable use, and the unit's controls, as well as a headphone jack and volume knob that are easy to reach.

The LEI-515 SDI Presence Detector from Link Electronics is a unit designed to monitor (2) serial component digital signals and automatically switch to a backup auxiliary source in instances of signal failure. This module also features "audio follow video" functionality, which is switched internally with a captive-screw terminal sub-module. This unit supports both Composite and Component video signals.

This unit's input receiver device monitors the incoming signal level and produces a DC voltage proportional to the amount of gain and equalization necessary to recover and reshape the signal. If automatic gain/EQ voltage exceeds the threshold voltage, this device will switch to auxiliary input.

Adjustment features give this unit the ability to select auxiliary input before data errors are visible in the primary input. Front panel switches allow you to override the automatic changeover functions and choose either video source. Dual front-panel LEDs indicate the presence or absence of video input signals. Switching is accomplished with an active 2:1 multiplexer and a 75Ω matched-impedance relay allows the input signal to pass through even if power is lost.

The RF Wireless Signal Detector from KJB Security Products is a counter-surveillance device which locates hidden bugs that send digital transmissions using standards like Bluetooth, Wi-Fi, and analog signals broadcast at up to 12 GHz. The unit can detect a variety of conventional bugging devices including FM-modulated transmitters, digital transmitters, GSM bugs, etc. Using sound to detect transmitters, the unit can produce a loop-back effect with a microphone to pick up and transmit the beep. When a signal is detected the demodulation display will flash and the detector will sound depending on the type of transmission detected. The extra antenna allows the device to avoid interference from external sources in cities or near broadcasting towers.
