Import 700m Wireless Av Sender For Cctv Camera — Buy in Bulk from Supplier in China

The 700m Wireless AV Sender from Shenzhen Pakite Net transmits analogue video and audio signals over the 2.4 GHz ISM frequency band, a licence-free spectrum segment used globally for short-range wireless devices. The manufacturer claims an operational transmission range of up to 350 metres without signal degradation, though this figure depends on line-of-sight conditions, antenna height, and local RF congestion from Wi-Fi networks, Bluetooth devices, and microwave ovens. The unit is compatible with composite video sources including CCTV cameras, DVD players, DVRs, IPTV set-top boxes, and satellite receivers, accepting standard RCA connectors for video and stereo audio. Power is typically supplied through a mains adapter, with the specific input voltage and current draw not stated in the source data. The product is positioned at security installers and systems integrators who need to extend camera feeds without trenching cables through existing structures.

The 2.4 GHz band offers 83.5 MHz of spectrum in most regions, divided into 14 channels of 22 MHz width with 5 MHz spacing, though channel overlap means only three non-overlapping channels (1, 6, 11) are usable for interference-free deployment. Shenzhen Pakite Net does not specify whether the sender uses fixed-frequency analogue modulation or frequency-hopping spread spectrum, nor does it state the occupied bandwidth or channel bandwidth. Typical 2.4 GHz AV senders in this class employ FM or AM modulation of the composite video signal, with audio sub-carriers at 5.5 MHz or 6.0 MHz depending on regional standard. Buyers should request the modulation scheme, actual transmit power in dBm or milliwatts, and receiver sensitivity figures to calculate link budget for their specific installation environment.

Intended buyers include CCTV installation contractors, retail security managers, and residential integrators who require rapid deployment without structural cabling permits. The 350 metre open-field range reduces substantially indoors; a rule of thumb is one-third to one-half through standard masonry, and less through reinforced concrete or metal-stud walls. The source mentions flexible MOQ but does not state a figure, nor does it list specific model numbers, FCC or CE certification identifiers, or RoHS compliance documentation. Incoterms and lead times are absent. Importers should request a sample unit for field range testing in their target environment before committing to volume, because 2.4 GHz propagation characteristics vary significantly with daylight hours, weather, and neighbouring RF activity.

Shenzhen Pakite Net is located at Futian Caitian Road, Guangzhou, 518000, Shenzhen, China. The address lists Guangzhou as the city in the street line while the postal code and administrative context place it in Shenzhen, a discrepancy that buyers should clarify with the supplier directly. The company holds an imported tier classification and a harbor trust tier on the platform. The response rate is recorded at 0.00 percent, with an average response time of zero hours, which suggests no platform-mediated communication has occurred or the supplier has not engaged with enquiries through this channel.

The supplier profile does not disclose year of establishment, number of employees, factory ownership status, annual turnover, or named clientele. No quality management certification (such as ISO 9001) or industry-specific accreditation is cited. The source description mentions relevant certifications without identifying standards or issuing bodies. Buyers should therefore treat the company as an unverified trading entity or manufacturer until independent due diligence is completed. A direct factory audit, video conference with engineering staff, or third-party verification through a service such as SGS or Bureau Veritas would provide necessary assurance before large-volume commitment.
