説明

Most cameras record. Very few of them remember on your behalf. The distance between footage and evidence is structure: eight channels arriving on one clock, one timeline, one index that can be searched by what moved instead of by the hour you happened to look.

The Sentry Ledger pairs an eight-channel 5-IN-1 DVR with four 3K 5MP weatherproof cameras and a 20 metre cable run for each. The recorder speaks every language an older building already contains - TVI, AHD, CVI, CVBS and IP - so a working analogue install does not have to be discarded to gain resolution. Recording and playback run at up to 3K Lite, and advanced H.265+ compression is what keeps the drive measured in weeks rather than in days.

The part that changes daily use is Motion Detection 2.0. Deep-learning classification separates human and vehicle targets from the moving branch, the passing shadow and the animal crossing the yard, so an alert is a decision instead of a notification. Live view reaches an iPhone, an iPad or an Android handset, HDMI and VGA outputs drive a local monitor up to 1080P, and audio travels back to the recorder on one RCA channel or eight channels over coaxial cable. In IP enhanced mode the same chassis accepts twelve channels.

This is not a camera kit. It is a searchable memory for the property you are responsible for.

Where It Belongs

This system belongs wherever a single vantage point is not enough. A courtyard with one entry road and three blind corners needs eight channels more than it needs one expensive camera. A workshop wants the door, the bay, the loading apron and the yard on the same timeline so a missing pallet can be traced in minutes. A farm or stable needs human and vehicle classification so that the movement that matters is separated from the movement that does not. Where a legacy analogue installation already exists, the 5-IN-1 input means the wiring stays and the resolution rises, which is the least expensive upgrade path available to most small sites.

Support That Answers

Every unit is checked before dispatch and shipped from the regional warehouse you select at checkout. Before purchase and after it, questions are answered by the same team that listed the product, not by a script.

Frequently Asked Questions

Q: Can this replace the analogue cameras I already have?

A: The DVR accepts TVI, AHD, CVI and CVBS signals alongside IP, so existing analogue cameras can stay on the cable while the 5MP cameras in the kit cover the positions that matter most. Image quality is decided per channel, which lets an upgrade happen in stages instead of in one purchase.

Q: How long will the recorder keep footage?

A: Retention is a function of channel count, resolution, motion load and drive size. Advanced H.265+ compression reduces the bitrate per stream, and the kit is offered with 1 TB, 2 TB or 4 TB drives; eight channels at 5MP on a 4 TB drive with H.265+ and motion-based recording is measured in weeks. Higher traffic areas shorten that window.

Q: Can it tell a person from a car?

A: Yes. Motion Detection 2.0 performs deep-learning human and vehicle target classification on all analogue channels, so those two classes can be selected for alerts while foliage, shadows and small animals are filtered out.

Q: Do the cameras work at night?

A: Each lens carries an IR cut filter that automatically switches the sensor between day and night capture, keeping daylight colour accurate and low-light performance usable. All four cameras are built for indoor and outdoor mounting.

Q: Can I watch the feeds from my phone?

A: Live view is supported on iPhone, iPad and Android devices, and HDMI or VGA outputs let a local monitor show the same channels up to 1080P.

Q: What is included, and can the system grow?

A: The kit is a complete eight-channel recorder with four 5MP cameras and 20 m of cable per camera, in the drive size you choose. Two IP channels can be added to the eight analogue inputs, and IP enhanced mode extends the recorder to twelve channels.

Q: Which warehouse ships my order?

A: Checkout offers the United States, Australia, Czech Republic, Spain and United Kingdom variants, so the kit can be dispatched from the regional warehouse closest to the delivery address.

Solid Kit, Plan Your Drive Size

Eight channels plus four cameras on 20m cables each - the recorder was set up in an afternoon. I started with 1TB and will move to 4TB because I keep 3K on all four cameras. H.265+ helps, just be realistic about retention.

Alerts That Actually Mean Something

Human and vehicle classification is the reason I replaced my old recorder. It used to ping on every passing cat and I had turned notifications off entirely. This one only flags people and cars, so I read the alerts again.

Replaced Four Cameras And Kept The Wiring

I was quoted for a complete reinstall because my old analogue cameras were supposedly obsolete. This kit took the existing coax and the 5MP cameras went onto the same runs. The 5-IN-1 inputs are the reason I bought it and phone viewing worked on the first attempt.
