SWaP stands for size, weight, and power. These three factors describe how much physical space equipment occupies, how heavy it is, and how much electrical power it consumes. SWaP-C adds cost to the evaluation, recognizing that integration and procurement decisions also depend on budget.
A low SWaP design provides the required functions within strict physical and energy limits. SWaP-C adds a fourth element: an option that saves weight or power may carry a higher purchase or integration cost.
Why SWaP-C Matters in Defense Systems
Every additional component competes for space, payload capacity, and available energy. On a UAV, extra weight can affect endurance and the payload available for cameras and other sensors. On a vehicle, electronic systems have to fit around existing equipment and operate within available electrical and cooling capacity.
Power consumption also affects heat generation. A device that consumes less power may be easier to integrate into a compact enclosure, but engineers have to consider processing capacity, input and output connections, environmental protection, and ability to maintain SWaP numbers.
These trade-offs are especially important in low SWaP systems for military and airborne applications. The design must support required video functions without exceeding the host platform’s limits.
Designing Video Systems for Low SWaP
Maris-Tech develops embedded video and edge-computing platforms for applications where conventional computing equipment may be too large or power-hungry. Depending on the product, a single unit can integrate video encoding, decoding, streaming, recording, and onboard processing functions.
Combining functions on a purpose-built platform can reduce the need for multiple separate devices, cables and power connections. Hardware acceleration and embedded processing architectures also help match computational capability to the available power budget. The appropriate design depends on the number of cameras, required resolution, video format, latency, and any onboard AI workload.
SWaP must be evaluated against the actual mission requirements. A platform supporting several high-resolution inputs may have a different power and thermal profile from a simpler single-camera encoder.
Where SWaP-C Matters Across Defense Platforms
Compact video systems are relevant to UAV payloads, autonomous platforms, armored vehicle upgrades, and deployable observation equipment. In each case, integrators must balance physical limits against the need for reliable video capture, processing, and transmission.
Maris-Tech offers compact embedded video-processing products and OEM modules for integration into larger systems. Engineers should check required interfaces, processing functions, environmental conditions, dimensions, weight, power draw, and cost against the relevant product specifications.
In practice, SWaP-C engineering is a balance between capability, size, weight, power, and cost. A product is suitable when it meets the mission’s requirements within the available integration budget and physical constraints.

Frequently Asked Questions
What do SWaP and SWaP-C stand for?
SWaP means size, weight, and power. SWaP-C includes cost as an additional design and procurement consideration.
Why are low SWaP systems important in defense?
Military and UAV platforms have limited space, payload capacity, and available power. Low SWaP systems help fit required capabilities within those constraints, while SWaP-C also accounts for cost.
How does Maris-Tech address SWaP-C requirements?
Maris-Tech integrates video-processing functions into compact embedded platforms. Integrators can compare each product’s published dimensions, weight, power requirements, and cost against their mission needs.
