H.264 Standalone DVR AB-H5004AL

The AB-H5004AL is a standalone digital video recorder that uses H.264 compression and supports triplex operation for up to four simultaneous users. It records up to 120 fps, offers loop‑through, composite/S‑VHS and VGA outputs, and includes audio and alarm inputs and outputs. The unit provides network connectivity via static or dynamic IP, RS‑485 for PTZ control, and optional secondary storage through USB or CD‑RW in AVI format.

The chassis is built from injection‑moulded ABS plastic, a common material for surveillance equipment, giving the device durability in indoor installations. Typical units of this class are rated for storage temperatures of - 20 °C to 65 °C and operating temperatures of - 5 °C to 50 °C with 20‑80 % relative humidity, matching the specifications listed. Standard industry practice is to use three 3.5‑inch HDDs, each up to 2 TB, although the supplier states unlimited HDD space within the three‑drive limit.

These DVRs are suited for small‑to‑medium security projects such as retail stores, offices, and remote monitoring stations where four camera feeds are required. The product ships with a standard 12 V DC, 5 A power adapter and can be ordered with bulk packaging; however, the exact minimum order quantity and incoterm details must be confirmed directly with the supplier. Prospective buyers should request a sample unit and verify firmware version before finalising a bulk purchase.

Abest Industrial Limited is based in Shenzhen, Guangdong Province, China, at Rm2010, Qing'an Hangkong Mansion Baguasi Rd, Futian District. The supplier is classified as an imported tier with a harbor trust tier, indicating that it participates in cross‑border trade and meets basic verification standards on the platform.

The company lists electronic surveillance products, including the AB‑H5004AL DVR, but does not disclose detailed corporate history, employee count, or revenue figures. Its response rate is currently recorded as 0 %, so buyers should initiate contact early and request a clear communication schedule before committing to large orders.
