HD21E – Airborne Ethernet IP Streaming Bullet Camera

The HD21E has the option for different cable configurations and different lens options.

Cable Type

HD21E standard model ships with a cable seal for the mating ethernet cable.  The 2.1×5.5mm barrel power connector includes a watertight plug for protection when not in use.  The cable extends ~17-18″ from the back of the camera to the connectors.

Factory Standard Model:  RV-CAM-HD21E-(_._mm)

HRS Power Connector

The power connector is available with a Hirose LF07WBJ-6P connector, or a customer-specified connector.

Lenses: RV-LENS-M12-##.##mm

The HD21E lens is protected by a scratch resistant polycarbonate window and sealed aluminum hood.  For the most demanding applications, a Sapphire window may be available.  HD21E has an IR cut filter installed on the image sensor by default.  Because the IMX327 sensor is sensitive to NIR wavelengths, daylight images would appear with a reddish tint without a filter.  Some lenses also have IR coatings or IR cut filters installed.  IR-filtered lenses are denoted with the “IR” suffix in the part number.

The HD21E Micro HD Bullet Camera has the option of lenses from 160 degree wide angle to 8 degree zoom.  Lenses are a fixed focal length M12 or S-Mount type with an adjustable focus.  Some lenses may not be compatible with the waterproof lens hood.

When referring to a single “FOV” angle, Rugged Video literature is considering the diagonal FOV; however, for many applications it is important to also know the horizontal and vertical angles.  The table below lists the actual FOV angles measured using most standard lenses with the HD21E camera.  To illustrate the effects of lens distortion, we have measured FOV at both the center and the edges of the image.  Measurements are provided for reference only and may be slightly different than those measured by different methods.

Additional focal lengths and vari-focal lenses are available as special order options.  While most lenses and lens hoods are stocked, some less common waterproof lens hoods may be non-stock with leadtimes of 4-8wks.

HD21E features a standard 1/4″-20 mounted boss on the back of the camera and a wrap around collar for use with standard camera mounts.  The aluminum collar is designed to reduce vibration and stress, by supporting the camera from the center mass.

Available Mounts

A number of off-the-shelf mounts are available for the HD21E, each using the standard 1/4″-20 stud.

Big Mite – is a cast aluminum collar, machined ball, and spud. The spud can be bolted directly to a solid surface using a #8 to 1/4″ flat machine screw.  The collar is then clamped to the spud and locks the ball in place.  The Big Mite is a larger version of the MiniMite designed to support larger cameras in high vibration environments.

Mini Mite – is a cast aluminum collar, machined ball, spud, and extension with a flat base option. The spud can be bolted directly to a solid surface using a #4 to #10 flat machine screw.  The collar is then clamped to the spud and locks the ball in place.  Alternatively the spud can be affixed to the flat base which can be attached to a solid surface using 4 x #4 or #6 screws.  The Mini Mite is designed for smaller cameras like the HD29, HD19, HD30, or HD21E.

Ultra-Clamp Mount – is a cast aluminum frame with a poly-carbonate injection molded adjustment attachment.  This mount is clamped to a secure bar or flat with a hand screw.  Additionally the top may be removed and mounted directly to any surface using a 1/4″-20 screw.  This mount can hold any size Rugged Video camera.	Ultra Clamp Mount with Adjuster Arm
Locking Suction Mount – Is an injection molded poly-carbonate mount with the same aluminum collar and ball as the Big Mite.  The suction mount features a wide cup that can attach to any smooth, hard, clean surface.  The suction cup is secured with a lever that creates additional vacuum within the cup.  This mount can hold any Rugged Video camera, but should only be used inside the cockpit for portable installations.  The mount is secured with air-pressure and thus should be tethered to avoid injury should a change in pressure occur, or the mount was to lose pressure.

2.1″ Pedestal Mount – is a cast aluminum collar, machined ball, and formed steel flat base with overall height of 2.1″. The base can be attached directly to a solid surface using 3 x #4 screws.  The ball is secured with friction by using a winged screw.  The pedestal is designed for smaller cameras like the HD29, HD19, HD30, or HD21E.
