Important Notice:
A hidden camera is a still or video camera used to film people without their knowledge. The camera is "hidden" because it is either not visible to the subject being filmed, or is disguised as another object. Hidden cameras have become popular for household surveillance, and can be built into common household objects such as smoke detectors, clock radios, motion detectors, ball caps, plants, and cell phones. Hidden cameras may also be used commercially or industrially as security cameras.
A hidden camera can be wired or wireless. The former will be connected to a TV, VCR, or DVR, whereas a wireless hidden camera can be used to transmit a video signal to a receiver within a small radius (up to a few hundred feet).

The Signal Analysis Meter is a full-featured handheld signal performance meter providing a complete signal test system in easy-to-carry protective case. Signal Analysis Meter allows choice of 4 pre-programmed user-selectable band plans accessed via keypad entry for easy measurement of broadcast, CATV, CATV/HRC, and SUB/VHF channels. Direct-entry channel or frequency tuning selections provide maximum flexibility in head-ends and distribution networks that employ narrow digital signals or non-standard frequency applications. The meter displays instantaneous digital signal levels when testing digital carrier levels. The large LCD screen displays signal level as a bar-graph with digital numeric readout. This backlit display provides screen illumination in dimly lit work-spaces, allowing behind rack and night meter operation. Signal Analysis Meter enables testing of carrier-to-noise, multiple channels, and full, reduced, and single band scan for complete testing flexibility. The meterí»s functions include not only signal measurement when AC/DC voltage is present under test, but, when selected, voltage-level display.
Full-channel operation 5-870MHZ Frequency Range
4-keypad channel plans (TV, CATV/STD,CATV/HRC,SUB/VHF) enable quick switching between sources
Single keypad frequency or channel selection provides compatibility with channel, data, and other narrow bandwidth carriers
Full spectrum-analyzer scan provides display of up to 100 channels simultaneously
Carrier-to-noise testing provides accurate testing of system performance anywhere in the head-end or distribution system
Large easy-to-read backlit Graphic LCD display provides quick-glance signal reference even in dimly lit work environments
AC/DC voltage readings and compatibility allow measurements through input connector, enabling signal and voltage measurements when voltage is present in tested signal without costly adapters
8-Hour rechargeable NiMH batteries provide cost savings
Automatic power shut-off feature extends time between recharges
Bright orange high impact plastic housing and soft leatherette-vinyl protective case with belt clip included
S8808 CATV Signal level meter is a measuring instrument especially designed for CATV technician. It is complete digital display with clear and correct reading and the using of microprocessor makes it has high capacity, more accurate and more flexible to operate. Meanwhile it has the character of small size, lightweight, and easy carrying, so it is more suitable to be used outside and fixing TV.
