Frequently Asked Questions
Why is my CCTV DVR not recording in Dhaka?
The most common causes are: (1) hard drive full — check available storage in DVR menu, (2) hard drive failed — DVR shows "HDD error" or "HDD not found," (3) recording schedule disabled accidentally, (4) hard drive not formatted for the DVR. BAYAS diagnoses DVR recording issues for BDT 700–1,200 and fixes on the same visit in most cases.
How much does DVR hard drive replacement cost in Dhaka?
A 1TB surveillance-grade HDD (Seagate SkyHawk or WD Purple) costs BDT 3,500–5,000 installed, including formatting and DVR configuration. 2TB: BDT 5,500–8,000. 4TB: BDT 9,000–13,000. Standard laptop or desktop HDDs should never be used in DVRs — they are not rated for continuous recording and fail within months.
Can BAYAS fix my Hikvision/Dahua DVR at my home in Dhaka?
Yes. BAYAS services Hikvision, Dahua, CP Plus, and generic DVRs at your home. We bring replacement HDDs, power supply units, and video cables to diagnose and fix on the spot. Password reset, remote viewing reconfiguration, and HDD replacement are all done at your location.
My CCTV remote viewing app stopped working — can you fix it?
Yes. Remote viewing failures after a router change or ISP IP update are the most common CCTV issue in Dhaka. BAYAS reconfigures port forwarding, DDNS, and DVR network settings on-site for BDT 700–1,500. We also set up Hik-Connect (Hikvision) or DMSS (Dahua) P2P cloud access which eliminates port forwarding entirely.
