HIKVISION - DS-2SF8C442MXG1-ELWY/14 - 4 MP, 42× Zoom, Dual-Channel PTZ

DS-2SF8C442MXG1-ELWY/14 — 4 MP, 42× Zoom, Dual-Channel PTZ

The DS-2SF8C442MXG1-ELWY/14 is a dual-channel PTZ: one fixed wide-angle camera that records continuously, and one 42× zoom PTZ in the same housing. That solves the problem every single-lens PTZ has — while the zoom is pointed at one thing, nothing is watching everywhere else. Here the fixed channel keeps recording the whole scene whatever the PTZ is doing.

Both channels are 4 MP on 1/1.8" sensors. The PTZ channel reaches 252 mm with IR to 300 m and 150 dB WDR; the fixed channel has white light to 30 m. Smart linkage (manual tracking, auto-tracking, tracking takeover, linked tracking capture) lets the fixed channel spot movement and hand the target to the PTZ to follow. One cable, one IP address, one licence on the recorder.

This is an 8-inch, 11.5 kg unit on 802.3bt PoE or 36 V, with the fuller analytics set — loitering, people gathering, fast moving and parking detection on top of the usual line crossing and intrusion. It is specified for large sites: a distribution yard, a compound, a long perimeter.

What you'll need

• An NVR with enough channels and bandwidth — a dual-channel camera uses two: see NVRs
• 802.3bt PoE or a 36 V supply at 2.5 A: see PoE switches
• A bracket rated for 11.5 kg, on a mounting that does not flex at 252 mm: see CCTV accessories

Frequently asked questions

What does dual-channel actually give me?

Two cameras in one housing on one cable. The fixed wide channel records the whole scene continuously, so you still have evidence of everything that happened while the PTZ was zoomed in elsewhere. On a single-lens PTZ, that footage simply does not exist.

Does it use two channels on my recorder?

Yes. Budget two channels and the bandwidth for both streams. That matters when you are sizing the NVR and the storage, so tell us how many of these you are fitting and we will work it out with you.

Will the PTZ follow a target automatically?

Yes. Hikvision lists manual tracking, auto-tracking, tracking takeover and linked tracking capture for this model — so as well as following a target it will grab a still at the moment of handover.

Will standard PoE power it?

No. It needs 802.3bt or a 36 V supply at 2.5 A. An 802.3af or 802.3at switch will not run it, and an undersized supply is the usual reason a PTZ resets when it moves.

How far does it see at night?

Hikvision quotes IR to 300 m on the PTZ channel and white light to 30 m on the fixed channel. That is the illumination range, not the identification range.
