Description
The Ajax DoorProtect Plus is a wireless sensor that monitors three distinct threat types on any door, window, or hatch it is fitted to. A reed switch detects when the opening is breached. An accelerometer detects shock, picking up impacts from forced entry, glass breaking nearby, or an attempt to hammer through the door. A tilt sensor detects the angular movement that occurs when someone tries to lever or prise the frame. Any one of these events can raise an alarm independently, or you can configure the hub to require more than one signal before escalating, depending on how you want to balance sensitivity and false alarm risk.
This listing is for the Ajax DoorProtect Plus in Black, professionally supplied and installed by CCTV Aware, Ajax Certified Specialists covering Essex, London, Hertfordshire, and Kent.
Three detection methods in one sensor
A basic contact sensor only tells you a door has been opened. The DoorProtect Plus also tells you when someone hit it, and when someone tried to force it without opening it at all. The shock sensor operates at three sensitivity levels, adjustable through the Ajax app, and includes an option to ignore single shock events so that a delivery driver dropping something nearby does not trigger a false alarm. The tilt sensor threshold is adjustable between 5 and 25 degrees, letting you tune precisely how much angular movement constitutes a genuine threat at your specific installation point.
Third-party detector input
The DoorProtect Plus includes a terminal for wiring in any third-party NC-type detector. This makes it straightforward to bring an existing wired sensor, such as a glass break detector or a smoke sensor at the same entry point, into the Ajax system through a single device rather than adding separate components for each signal.
Two magnets, five years of battery life
The kit includes both a large and a small magnet, giving you more installation options depending on the gap and frame type at each door or window. The sensor runs on a single pre-installed CR123A battery with a calculated life of up to five years. It connects to your Ajax Hub 2 or range extender at a radio range of up to 1,200 metres, with tamper detection active throughout.

Yes. We can install CCTV as discreetly as possible, depending on your property and coverage requirements.
Options can include:
- Compact camera styles
- Higher mounting positions where appropriate
- Tidy cable routes and minimal visible trunking
- Recorder installed out of sight in a secure location
If your priority is a low profile install, tell us at quotation stage so we can recommend the best approach for your layout.
The recorder (DVR or NVR) is normally installed indoors in a secure, sensible location with good ventilation.
Common locations include:
- A cupboard or utility area
- An office
- A comms cabinet or rack
We typically install it near your internet router if you want remote viewing on your phone, as it needs a network connection.
If you have a preferred location, let us know during the quote stage and we will advise if it is suitable.
In many cases, yes.
Whether you can add cameras later depends on:
- How many spare channels your recorder has
- Whether the recorder has spare capacity on the hard drive
- Whether cable routes and power options are available
If you think you might expand in future, we can design the system with this in mind, for example fitting an 8 channel recorder for a 4 camera install, or leaving suitable cable routes.
Yes. Your CCTV system records locally to the recorder (DVR or NVR). If your broadband drops out, it will still continue recording as normal.
What you will lose during an internet outage is:
- Remote viewing from your phone or PC
- Push notifications and alerts to your phone
- Remote playback access
Once the internet comes back online, remote viewing and notifications will resume.
Recording time, also known as retention, depends on a few things:
- Number of cameras
- Camera resolution (for example 6MP, 8MP)
- Recording mode (continuous 24/7, motion only, or a mix)
- Frame rate and bitrate settings
- The hard drive size fitted to your recorder
As a rough guide, higher resolution and 24/7 recording will reduce retention. Motion based recording can greatly increase retention, but it depends on how busy the scene is.
We generally specify our systems to give you a retention period of 21 days.
Hikvision CCTV systems can support a multitude of notifications that can be configured to perform various actions from alerting your mobile phone to activating a parking barrier.
That being said, this guide talks about the three main notification options.
Motion Detection
In its simplest form, this is when an object enters the camera view area and a motion is triggered.
Line Crossing
An invisible line can be drawn on a particular area of your camera view area, for example the driveway threshold or the garden boundary. Once an object crosses over that line (from either way) - a line crossing is triggered.
Intrusion Detection
This is similar to Motion Detection but more specific. With Intrusion Detection an invisible quadrilateral shape can be drawn on a particular area of your camera view, for example directly outside your front door. Once an object then enters that area - an intrusion detection is triggered.
With all of the options above, the system is unable to detect the difference between a human, pet or other object. This can often result in false notifications being triggered to the user. In addition to this, if the system generates the notification - it is then down to your broadband provider (router) to push the notification out to your mobile device. This will often fail if your provider is not quite up to scratch or your mobile phone is currently in an area with poor coverage.
Because of this, we do not provide support on notifications that are sent to your mobile device.
Unfortunately, no.
We are authorised and Certified by Hikvision UK to supply and install their products.
We are unable to provide you with an installation only service if you have purchased your own equipment as we are not insured to do so.
