Speco VLD2A — Multi-Format HD Analog Dome Camera User Manual

User manual for the Speco VLD2A Multi-Format HD Analog Dome Camera — covers safety warnings, device framework, DIP switch output mode selection, and installation steps.

Overview

This series HDTVI camera conforms to the HDTVI standard and supports high-speed, long-distance video signal transmission without delay.

Features

• High-performance CMOS image sensor, megapixel definition
• Supports HD video and control signal coaxial transmission
• 720P series: RG59 coaxial cable transmission without loss up to 800m
• 1080P / 4M series: RG59 coaxial cable transmission without loss up to 500m
• Supports HDTVI/HDCVI, AHD, and Analog outputs
• ICR switch for day/night surveillance
• OSD menu parameter adjustment
• Smart IR and DWDR functions
• DC12V power supply
• IP67 and IK10 compliant (weatherproof and impact resistant)
• Suited for retail stores, supermarkets, coffee shops, schools, hotels, office buildings, restaurants, etc.

Safety Warnings

• Power must conform to SELV (Safety Extra Low Voltage) requirements — Limited Power Source rated DC 12V or AC 24V per IEC60950-1 (check the device label for actual requirement).
• Do not connect two or more power supply sources to the device simultaneously — this may cause device damage.
• Install an easy-to-access power disconnect device before wiring, for emergency power-off.
• Do not aim the camera at strong light sources (sunlight, direct lighting) — can cause overexposure and reduce CCD/CMOS longevity.
• Keep the device within its rated humidity/temperature range; avoid wet, dusty, extremely hot/cold, or electromagnetically noisy environments.
• Do not allow water or liquid to enter the camera — may damage internal components or cause fire/lightning risk on indoor units exposed to damp.
• Do not touch the heat dissipation component directly (scald risk); do not disassemble — no user-serviceable parts inside.
• Use of a thunder-proof/surge device and proper grounding of the product's grounding holes is recommended.
• Never touch the CCD/CMOS optic directly; use a blower or alcohol-dampened dry cloth to clean the lens if needed.
• For the dome cover (optical component): remove dirt gently with an oil-free soft brush; for grease/fingerprints, wipe dry first, then clean from lens center outward with oil-free cotton or alcohol-soaked cloth.

Device Framework

The device has three physical connection points: a DC12V power input port, a BNC video output port, and a DIP switch for output mode selection.

DIP Switch — Output Mode Selection

Switch is ON when moved upward, OFF when moved downward.

Installation

Important: Before installing, confirm the mounting surface can sustain at least 3× the combined weight of the bracket and camera.

1. Use a wrench to loosen the three fixing screws on the enclosure and remove the dome cover.
2. Confirm the installation location and drill mounting holes.
3. Insert expansion bolts into the holes and fix them firmly.
4. Position the pedestal, pull the cable through the mounting hole, align the pedestal's bolt holes with the expansion bolts, then insert and fasten self-tapping screws to secure the pedestal.
5. Connect the video output port to the back-end encoding device and connect power.
6. Adjust the lens angle to the desired monitoring position while viewing the image on the back-end device.
7. Lock the fixing screws firmly and reattach the dome enclosure to the pedestal.

Once complete, verify the monitoring video via the back-end encoding device.
