Zenith Security Co. ZS-SPC/37 Mini Screw-Head Hidden Pinhole CCTV Camera (Analogue, 800TVL, Audio)
Product Features
- Covert 9 mm camera disguised as a screw head — 3.7 mm pinhole lens, 70° view
- Standard-definition analogue (CVBS) colour video, approx. 800 TV lines, PAL/NTSC — not HD
- Built-in microphone with separate audio output
- 12 V DC, 70 mA (power supply not included); yellow = video, red = 12 V, white = audio
- Connects to any DVR or XVR with an analogue (CVBS) channel — most Hikvision, HiLook and Dahua Turbo HD / XVR recorders
The ZS-SPC/37 is a tiny colour pinhole camera whose lens sits behind what looks like an ordinary screw head, so it can be fitted flush into a panel, shelf edge, ceiling tile or cabinet where a visible camera would be noticed. It is an analogue, standard-definition (CVBS) camera — around 800 TV lines, PAL 786 × 576 — not a high-definition camera, and it is intended for adding a discreet channel to an existing DVR rather than for identification-quality footage. It has a built-in microphone; recording audio is regulated more strictly than video in the UK, so check the covert camera guidance before enabling it.

What you need to use it
- A DVR or XVR with a spare analogue (CVBS) channel. Most Hikvision, HiLook and Dahua Turbo HD / XVR recorders accept CVBS on their coax inputs; an IP-only NVR will not.
- A 12 V DC supply — a spare output on a multi-way CCTV power supply is ideal.
- RG59 or shotgun coax back to the recorder, terminated with a BNC — see bulk coaxial cable.
For a higher-resolution covert camera, see the 2 MP Dahua HAC-HUM3201B HD-CVI pinhole or the 2 MP IP pinhole camera. Sizes are measured by hand; allow 1–3 mm. Call 01902 902251 if you are unsure whether your recorder will accept it.
