BT 1000-7SS1 Digital Baby Monitor Teardown

23 July 2013
The following is an overview of a teardown analysis conducted by IHS Benchmarking.

Summary Points

BT Digital Video Baby Monitor 1000

  • Basic Package includes one baby (camera) monitor and one parent unit
  • Can connect up to 4 cameras
  • 2.8 Inch LCD color screen on parent unit
  • Device features 'Speed-Pixel' ISM (2.4GHz) communications
  • Plastics, enclosures and box contents have a potential to be higher than our estimates because of very low volume and brief lifetime. Much of this should be 'outside' our analysis as NRE charges and tooling are usually handled separately, as transactions, from per item charges,

Pricing and Availability

Volume Estimations

7,500 Annual Production Volume
1 Product Lifetime (Years)

For the purposes of this teardown analysis, we have assumed an Annual Production Volume of 7500 units and a Product Lifetime Volume of 1 year(s).

Teardown volume and production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

Not Included in Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

We do provide an Excel tab 'Overall Costs' where a user can enter their known pre and post production costs to build a per unit cost reflective of theirs actual expenditures.

Country of Origin

For the purposes of this analysis, we are assuming the following country(ies) of origin for each level of assembly, based on a combination of 'Made In' markings, and/or assumptions based on our knowledge of such equipment.

Baby Unit - China
Box Contents - China
Parent Unit - China

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as combo modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. "Auto inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design Complexity

Component counts by assembly and the number of assembly are indicators of design complexity and efficiency.

Component Qty: 514 - Parent Unit
Component Qty: 549 - Baby Unit
Component Qty: 12 - Box Contents
Component Qty: 1075 - Grand Total
