Prison Video Intercoms in Correctional Facilities: Two Real-World Project Examples
Correctional facilities often need more than a standard telephone.
In locations where staff need visual identification, controlled communication or direct interaction between secure areas, a prison video intercom can provide a more suitable communication point than a voice-only telephone.
The challenge is that equipment used in prisons, jails and detention facilities must also be physically robust, easy to operate and compatible with the facility’s communication architecture.
This case study looks at two correctional projects that used IP video prison communication terminals in real installations and explains what engineers and integrators can learn from them.
Why Use a Prison Video Intercom?
A prison video intercom combines voice communication with a camera and display in a fixed, rugged terminal.
Depending on the project configuration, this type of equipment can be used for:
secure communication points
housing units
controlled access areas
visitation locations
staff-to-occupant communication
identification before access is granted
direct communication with a control room
For correctional projects, the main question is not simply whether a terminal supports video.
The more important questions are:
Where will it be installed? Who will use it? How will calls be routed? What level of vandal resistance is required? And how will the terminal connect to the existing SIP or IP infrastructure?
These questions are especially important because correctional communication equipment is often installed in high-use, security-sensitive areas.
Project Example 1: IP Video Prison Phones for a Correctional Facility in Colombia
One documented correctional project used 200 IP video prison phones for a prison installation in Colombia. The project reference identifies the equipment as an IP video prison phone deployment for El Salvador Prison.
Photographs from the project show fixed wall-mounted communication terminals installed inside the facility, with a handset and large integrated display.
This type of installation illustrates an important point for correctional communication design:
The terminal becomes part of the building infrastructure
A prison video phone is not a portable device.
It is a fixed communication point that needs to be considered together with:
wall mounting
cable routing
network access
power
user reach
viewing angle
handset position
control-room routing
That means the terminal should be selected early enough in the project that mounting and network requirements can be coordinated with the rest of the facility.
Video changes the communication workflow
A standard inmate telephone is mainly a voice endpoint.
A video terminal can support applications where the receiving party needs visual information as part of the interaction.
That may be useful in controlled communication, access, visitation or staff-supervised applications.
The exact function depends on the software platform and facility operating procedures, so the video terminal itself should not be treated as a complete prison management system.
It is better to think of it as a rugged video communication endpoint within a larger SIP, control-room or facility communication architecture.
Project Example 2: Large IP Video Prison Phone Deployment in Hong Kong
A second documented project involved 350 IP video prison phones for a correctional facility in Hong Kong.
The project images show multiple video communication stations installed in individual booth-style positions, indicating a larger multi-user deployment rather than a single security intercom.
This type of project highlights a different design challenge:
Large deployments require repeatable installation
When hundreds of terminals are involved, consistency becomes important.
Engineers and integrators need to consider:
consistent mounting height
repeatable cable entry
network addressing
SIP provisioning
power distribution
terminal labeling
maintenance access
spare equipment strategy
standardized configuration
The equipment itself is only one part of the project.
A 300-unit installation becomes an infrastructure deployment.
That means documentation, provisioning and serviceability matter almost as much as the physical terminal.
What These Two Projects Tell Us
The two documented projects together account for 550 IP video prison phone units: 200 in one correctional project and 350 in another.
The important lesson is not the quantity alone.
The projects show that fixed video communication terminals can be used both as:
individual secure communication points
and as
large-scale multi-station communication systems.
That distinction matters when specifying equipment.
A single secure-door video intercom and a 300-terminal inmate communication system may use similar endpoint technology, but the system architecture behind them can be very different.
What to Consider When Specifying a Prison Video Intercom
For engineers and security integrators, several points should be reviewed before selecting a terminal.
1. Physical construction
Correctional equipment should be selected for the actual installation environment.
Important considerations can include:
metal construction
tamper-resistant mounting
protected controls
handset protection
reinforced cord
flush or surface mounting
resistance to heavy daily use
The required design depends on whether the terminal is installed in a staff-controlled location, visitation area, housing unit or other secure space.
2. Voice and video requirements
Not every correctional communication point needs video.
Voice-only phones may still be more appropriate where the main requirement is simple calling.
Video becomes more useful where visual communication is part of the operational process.
Examples may include:
controlled access
supervised communication
visitation
identification
staff-to-secure-area communication
3. SIP and network integration
For an IP-based prison video intercom, the terminal should be evaluated as part of the wider communication network.
Typical architecture may look like:
Prison Video Intercom → Ethernet / PoE → SIP Platform / IP PBX → Control Room or Authorized Endpoint
Compatibility with the selected PBX, SIP server or video platform should be confirmed during project design.
4. Power
PoE can simplify installation where supported because power and network connectivity can share the same Ethernet infrastructure.
But PoE availability, switch capacity and cable length still need to be checked during system design.
5. Call routing
Before ordering equipment, the project team should define where calls go.
For example:
control room
security desk
staff station
visitation endpoint
central communications room
A video intercom should be configured around the facility workflow, not the other way around.
6. Maintenance and replacement
For large correctional projects, spare units, configuration backups and replacement procedures should be planned in advance.
A system with hundreds of endpoints should not depend on individually rebuilding each unit after replacement.
LightCom LC213-KB-DP-S for Correctional Video Communication
For projects requiring a vandal-resistant SIP video communication terminal, LightCom offers the LC213-KB-DP-S Vandal-Resistant SIP Video Intercom with LCD Keypad.
Product details:
The LC213-KB-DP-S is intended for secure communication applications where voice, video, display and keypad functionality are required in one fixed terminal.
Typical correctional applications may include:
secure access points
controlled communication areas
visitation locations
housing-unit communication
staff-to-occupant communication
corridor communication
control-room-connected video stations
For large projects, the terminal configuration should be reviewed together with the SIP platform, network architecture, mounting location and required user workflow.
Prison Video Intercom vs Standard Inmate Phone
The two product types should not be treated as direct replacements for each other.
A standard inmate phone is usually the better choice when the requirement is simply:
pick up handset → place or receive controlled voice call.
A prison video intercom is more appropriate where the project requires an additional visual communication layer.
In practice, many correctional facilities may use both.
For example:
housing unit: rugged inmate telephone
secure entrance: video intercom
visitation: video terminal
staff area: SIP telephone
help point: fixed intercom
This is usually more practical than trying to use one type of device for every location.
A Useful Design Principle
One lesson from real correctional projects is that the best communication terminal is not always the one with the most features.
It is the one that fits the exact location and workflow.
Before selecting a prison video phone or intercom, project teams should ask:
Who is using it?
Who are they calling?
Is video actually required?
How will it connect to the network?
How will it be mounted and protected?
How will replacement and maintenance be handled?
If those questions are answered first, product selection becomes much easier.
Conclusion
Prison video intercoms can be an effective part of modern correctional communication systems, particularly where fixed voice and visual communication need to be combined.
The documented projects reviewed here show that IP video prison communication terminals have been deployed both in large-scale installations and controlled communication environments, including projects with hundreds of endpoints.
For engineers, integrators and correctional facility project teams, the key is to treat the terminal as part of the overall communication architecture—not as an isolated device.
LightCom’s LC213-KB-DP-S provides a vandal-resistant SIP video endpoint for projects requiring voice, video, display and keypad functionality in a fixed correctional communication terminal.
