Frequently Asked Questions

For homes, a 4 to 8 channel DVR or NVR kit with 2MP or 4MP cameras gives clear footage and covers typical property sizes. Hikvision, Dahua and EZVIZ are popular choices. For wire-free setups, EZVIZ Wi-Fi cameras are a common option.

DVRs process analogue HD-TVI or HD-CVI cameras over coax cable. NVRs process IP cameras over Ethernet, usually with PoE power. IP and NVR offer higher resolution and smarter analytics; analogue is cheaper and simpler to cable in existing homes.

Yes — without storage the system cannot record. For 4 cameras recording 24/7 at 2MP plan on 1TB; for 8 cameras plan on 2TB or more. Use surveillance-grade drives such as WD Purple or Seagate Skyhawk for continuous write reliability.

Most modern systems include free mobile apps — Hik-Connect for Hikvision, gDMSS for Dahua, EZVIZ App for EZVIZ. Setup is typically a QR scan from the recorder plus an account login.
