Installers needing a compact wired bullet camera

This camera suits installers who need a small-form-factor analog camera for outdoor or indoor surveillance. The IP67 weatherproof rating supports exposed mounting. OSD configuration is handled via an AD-Key remote controller. Buyers who require integrated infrared LEDs for zero-light recording should consider other models. The fixed 3.7 mm focal length does not allow optical zoom or field-of-view adjustment.

3.7 mm fixed lens focal length

The 3.70 mm fixed board lens determines the viewing angle and identification distance for every installation. A wider lens would cover more area but reduce detail at range. A narrower lens would increase detail but limit coverage. Verify that this focal length matches the scene width and target distance required for the specific mounting position.

Questions about this item

What type of recorder or monitor must I already have to connect this 1920 x 1080 analog camera?

You need a DVR or monitor that accepts a standard analog video cable input, as the camera transmits over a wired cable connection.

Will this 3.7 mm lens camera work with the existing coaxial cabling I already have installed?

Yes, the camera uses a standard cable connection compatible with typical coaxial infrastructure used for analog CCTV systems.

How can I verify the 0.1 Lux low-light performance is functioning after installation?

Check the live feed in dim conditions; the OSD menu, accessible via the AD-Key remote controller, lets you confirm 3D DNR, BLC and D-WDR are active.
