Analog wireless is found in three frequencies: 900 MHz, 2.4 GHz, and 5.8 GHz. Currently, the majority of wireless security cameras operate on the 2.4 GHz frequency. Most household routers, cordless phones, video game controllers, and microwaves operate on the 2.4 GHz frequency and may cause interference with a wireless security camera.
The common nighthawk or bullbat (Chordeiles minor) is a medium-sized [3] [4] crepuscular or nocturnal bird [3] [5] of the Americas within the nightjar (Caprimulgidae) family, whose presence and identity are best revealed by its vocalization.
Nightjars can occupy all elevations from sea level to 4,200 m (13,800 ft), and a number of species are montane specialists. Nightjars occupy a wide range of habitats, from deserts to rainforests but are most common in open country with some vegetation. [8] The nighthawks are confined to the New World, and the eared nightjars to Asia and ...
When roosting on the ground during the day, this medium-sized (20–23 centimetres (7.9–9.1 in) long) nightjar is mainly variegated grey, with a browner collar. It has a shadowy form with easy, silent moth-like flight; this nightjar is relatively short-tailed, and lacks white in the wings or tail. The song is a churring trill.
While most individual nodes in a WSAN are expected to have limited range (Bluetooth, Zigbee, 6LoWPAN, etc.), particular nodes may be capable of more expansive communications (Wi-Fi, Cellular networks, etc.) and any individual WSAN can span a wide geographical range. An example of a WSAN would be a collection of sensors arranged throughout an ...

The least nighthawk (Chordeiles pusillus), at 6.3 inches (15–19 cm) and 23 grams (0.81 oz), is the smallest of all Caprimulgiformes, while the Nacunda nighthawk (Chordeiles nacunda) is one of the largest nightjars in the world measuring at 11-13 inches (28–33 cm).
Six specimens of nacunda nighthawk were found to average 159 g (5.6 oz) in body mass, with range of 130 to 188 g (4.6 to 6.6 oz). [5] Its very large size, large head, and pale body with highly contrasting black primaries make the nacunda nighthawk easy to identify. [6] This species is noteworthy for its partially diurnal habits.
