And close enough, because sometimes the threat of security will do. Our simulacamera looks like the real thing, even though it isn't, with an activation light and a quite real motion detector that causes the "camera" to pan from side to side. The unit measures 3-3/4" x 2" x 2" with a 1-1/4" dia lens. It's mounted on an adjustable 4" x 1-1/8" x 3/4" arm attached to 3-1/8" dia baseplate with (2) 3/16" mounting holes. The angle adjusts from 45 to 180 degrees, and the motion detector starts the head swinging 20 degrees in either direction for approx (15) seconds. Takes (2) "AA" batteries, not included, but does include mounting screws and mollies-and a tiny, tiny price.

92835 DETECTOR CAMERA |
The in-between aluminum tripod: bigger than a mini but a lot easier to tote than a full-size version. Collapses to 14-3/4" long x a triangle approx 2-1/2" on a side. Has 4-draw legs with clutches that extend (3) feet, and a shaft that pulls up another 12" to a full 4-foot height. Includes a 1/4"-20 standard camera thread. Very useful item for small digital camera users.

38831 TRIPOD |
Direct from the U.S. Army, this desert-tan nylon pouch was made to hold a 2-qt non-sloshing bladder canteen. So authentic that it probably will have the original stenciling and user's name on it. Has a plastic latch, belt clips, an adjustable and detachable 42" shoulder strap. The cushy fake-fur lining insulates it in the winter. Wet the lining for a cooling effect in hot weather. Measures 8-1/4" x 7" x 3" with a little 3" x 2-1/4" pocket on the front. (Water purification tablets?) Don't carry water? It'd make a nice, warm traveling gerbil habitat. (There's even a drain hole in the bottom.)
