What the AI looks for in Surveillance Accessories

Surveillance hard drives
Use surveillance-class drives (for example WD Purple or Seagate SkyHawk) in NVRs and DVRs, and check the recorder's maximum supported capacity. They are designed for continuous multi-stream writes, and recorders cap the drive size they recognize.
Network cable
Use solid pure-copper Cat5e or Cat6, with outdoor/UV-rated jacket for exterior runs, and keep runs within 100 m. Copper-clad aluminum (CCA) cable causes PoE voltage drop and failures, and indoor jackets crack outdoors.
PoE switches and injectors
Match the standard (802.3af, 802.3at/PoE+, or 802.3bt) to each camera and confirm the total power budget exceeds the sum of all cameras. PTZ and IR-heavy cameras draw more power, and passive 24V injectors can damage standard PoE devices.
microSD cards
Use high-endurance cards made for continuous recording, within the camera's maximum supported capacity. Ordinary cards wear out quickly under constant writes.
Mounts and junction boxes
Buy mounts and junction boxes listed for your exact camera model or the same brand's housing pattern. Screw patterns and housing shapes vary by brand and model.
Analog connectors
For analog HD systems, match BNC connectors and siamese (coax + power) cable to the DVR and camera type. Mixing standards or using poor connectors causes video loss and interference.

Brands that matter

  • WD Purple: Western Digital's surveillance-class hard drive line.
  • Seagate SkyHawk: Seagate's surveillance-class hard drive line.
  • SanDisk: High Endurance microSD cards for dashcams and cameras.
  • Samsung: PRO Endurance microSD cards for continuous recording.
  • TP-Link: Affordable unmanaged and managed PoE switches.
  • Netgear: Reliable PoE switches with clearly stated power budgets.
  • Ubiquiti: UniFi PoE switches for UniFi-based systems.

What to avoid

  • Copper-clad aluminum (CCA) Ethernet cable for PoE runs
  • Desktop hard drives in a 24/7 recorder
  • Standard microSD cards in continuously recording cameras
  • Passive or non-standard PoE injectors with 802.3af/at cameras
  • Generic mounts with no stated compatibility for your camera model

Questions

Do I need a separate PoE switch if my NVR has PoE ports?

Only if you need more camera ports or more power budget than the NVR provides, or if cameras are too far from the NVR for a single cable run.
