Compatibility guidance and accessories

Many modules are designed for popular development platforms and are widely compatible with Raspberry Pi and microcontroller boards. When selecting accessories, consider connector type (BNC, SMA, F-type), impedance (50 vs 75 ohm) and power method (PoE vs local PSU). For a broader product view, visit All Products.

Selection criteria, troubleshooting and buying tips

Select by signal, connector and power

Start with the signal type (analogue RF, digital TV, IP video) and then pick the matching connectors and cables. For example, CCTV and many consumer video systems use 75 ohm coax with BNC or F-type connectors; professional RF often uses 50 ohm SMA or N-type. Check component pages for compatibility notes on connector gender and impedance.

Basic formulas and calculations

Use these quick checks when planning installations:

• Ohm's Law: V = I × R - verify supply voltage and current draw for cameras and encoders.
• Power: P (W) = V × I - size your power supplies with a safety margin (~20%).
• Cable loss: Longer coax or high-frequency runs increase attenuation; choose lower-loss cable or add amplifiers where needed.

Troubleshooting checklist

• No picture: confirm power, check cable continuity and connector seating.
• Poor reception: check antenna orientation and use proper impedance-matching components.
• Intermittent network stream: verify PoE power class, switch ports and bandwidth usage.
