With an operating temperature range of 41-113 degrees F (5-45 degrees C), the TV-IP301W is clearly not designed to be an outdoor camera. It does have a heavy, solid feel since it is housed in an aluminum case and weighs in at 450g (15.9 oz).
The case is held together with two long screws that run from the back of the camera, through an extruded channel to the front of the camera. Removing those two screws and the antenna/antenna connector allows the case to slip apart.
Inside, you'll find a motherboard that's connected to a daughter board that contains the RF components, the I/O connector, and the microphone/audio out jacks.

The two boards, shown in Figure 3 above, plug into a third board (refer to Figure 4) that's mounted behind the lens assembly.

Pulling the two circuit boards apart reveals the RF module, shown in Figure 5 below. The wireless module is an OEM RF module made by Cellvision Systems in Taiwan. It uses a Ralink RT2500 802.11b/g Chipset.
