Ltl Acorn 6210 Water Resistance Tests

Ltl Acorn 6210MMX

Don't all die of shock. This is what we've all been waiting for.
A 6210 with a water tight case.

Camera under test: 

Ltl Acorn 6210MG S/N 202001037 – This test camera is the re-designed case as of October 2012

Purpose of test: 

To determine its resistance to water ingress during heavy rainfall with at least a ten degrees centigrade drop in case temperature during the first five minutes from the start of the test.

Reason for test:

The camera case is a sealed unit at normal air pressure but with any sudden drop in external case temperature (e.g. cold heavy rain following heating by sun), the air inside starts to contract and form a vacuum. As the vacuum increases any weakness in the case seals will cause the seal to break down at some point and

Ltl Acorn 6210 Water Resistance - Final Analysis

Acorn 6210 water/condensation problem update 07.07.2012

I'm very happy and relieved to be able to say that the reason for the condensation problem in the Ltl Acorn 6210 Trail Camera has been identified.

After lengthy tests and analysis the cause of water getting into the control panel is, at long last, understood; and some final changes to the case upgrade are now being made.

I don't know exactly how long this will take, but it will be as fast as possible.

I will post a full explanation of the problem and how it was solved at a later date. Users of cameras which have this problem should remove the rubber bung (external power supply input) from the base of the camera.

Since its launch at the end of 2011 the Acorn 6210 has had a problem with water entering the case. At first faulty sealing around the PIR detector windows was thought to be the reason; but it rapidly became apparent that water was entering around the bottom door seal.

Figure 1 shows a gap in the case rib which runs around the front and sides of the bottom of the case. This rib buts against the seal in the door and for some reason it was not continued along the back edge in front of the hinge. This has since been identified as the reason for water ingress of the control panel.

Figures 2 and 3 show the effect of water collecting in the bottom door and soaking into the screen layers. Water also gets into the control panel switches, causing random signals to the control electronics and making the camera unusable until it has been thoroughly dried out.

Figure 4 illustrates the secondary issue of condensation. Fogging of the camera lens is caused when the body of the camera heats up in the sun and evaporates water from the control panel into the
