Analogue CCTV was supposed to be dead, and it is not, for one practical reason: existing coax cabling works and replacing it costs more than the cameras. The Sentry Eight is built for that reality. It delivers 8 megapixels over standard BNC coax at AHD resolution, so a system installed years ago can move from 2MP to 8MP by changing the camera rather than the wire in the wall.
The imaging chain is the part that decides whether 8MP is real or interpolated. A Sony CCD sensor at 1/3 inch with a 3.6mm lens produces a genuine 3840 by 2160 style frame detail level with a 90-degree viewing angle, which is wide enough to cover a driveway or a shopfront corner without the fisheye distortion of a 2.8mm lens. H.265 compression halves the bitrate against H.264 at equivalent quality, which is what lets an older recorder keep its retention window at the higher resolution.
Night performance uses full-colour rather than infrared-only, with an IR-cut filter that switches automatically at dusk. That combination gives colour identification under low light, which matters because a colour image of a face or a vehicle is worth more than a monochrome silhouette. Face detection, face recording and playback are handled in the camera, so the recorder does not need to be capable of analytics itself.
The housing is metal and rated IP66, mounted as a bullet on wall or soffit with the cable exiting through the base. It is a closed-system camera, which means it expects a DVR rather than an app, and it comes with a three-year warranty, which is longer than the one-year norm for this class.
Resolution only matters if the recorder can keep it and the lens can frame it.
Key Features
- True 8MP AHD Full 8 megapixel detail over coax BNC, an upgrade path for existing analogue systems.
- Sony CCD sensor 1/3-inch sensor with a 3.6mm lens for genuine detail rather than upscaled interpolation.
- Full-colour night vision IR-cut filter switches automatically at dusk so night footage stays in colour.
- H.265 compression Roughly half the bitrate of H.264, which preserves retention at higher resolution.
- 90-degree viewing angle Wide enough for a driveway or shopfront without the distortion of an ultra-wide lens.
- On-camera face detection Face recording and playback handled in the camera, so the DVR needs no analytics.
- Metal IP66 housing Weatherproof bullet body for indoor and outdoor mounting in rain and dust.
- Three-year warranty Longer than the one-year cover typical of this class of camera.

Where It Belongs
This is the camera for a shop, a yard, a small warehouse or a home perimeter where coax is already in place and a full IP refit is not justified. It suits the owner replacing failing 2MP cameras one at a time, and the installer who wants colour night footage without buying an NVR. Because analytics sit in the camera, it also upgrades an older DVR that has no detection features of its own.
Frequently Asked Questions
Q: Will this work with my existing DVR?
A: It needs an AHD-capable DVR, which most units made after 2017 are. Check that your recorder supports 8MP AHD and H.265 before ordering, since an older 2MP recorder will downscale the image.
Q: Does it need a separate power supply?
A: Yes, it uses a standard 12V DC feed alongside the BNC video cable, unless your DVR supplies power over the coax. Most installations already have that pair in place.
Q: Is the night footage really in colour?
A: It is colour under low light rather than in complete darkness. With some ambient light, street lamps or a security light, the image stays in colour; in total darkness it falls back to infrared.
Q: Can I view it on a phone?
A: Yes, through the DVR app rather than the camera itself. The camera is a closed-system device, so remote viewing is handled by the recorder.
Q: What does face detection actually do?
A: It recognises and records faces within the frame and can trigger an email snapshot. It is not facial recognition against a database, so it flags that a face was present rather than who it was.
Q: How far can it identify a person?
A: With 8MP on a 3.6mm lens, expect useful identification at roughly 10 to 15 metres in daylight. Beyond that the frame stays wide but facial detail drops off.
Q: Is the housing really metal?
A: Yes, a metal bullet body rated IP66. That is the reason it survives coastal air and direct rain better than the plastic housings common at lower price points.
